The Edwards MC3 Tricuspid annuloplasty ring, Model 4900, is intended for use in patients to correct annular dilatation, increase leaflet coaptation, reinforce annular suture lines, and prevent further dilatation of the annulus.

The Edwards MC3 Tricuspid annuloplasty ring, model 4900, consists of two primary components: the implantable annuloplasty ring and the template/ lanyard assembly (or holder). The implantable annuloplasty ring is constructed of titanium alloy and has a sewing ring margin that consists of a layer of silicone rubber, covered with polyester velour cloth sewn with a single seam.

The Edwards MC3 Tricuspid annuloplasty ring can be used in tricuspid valve repairs. The oval tricuspid ring conforms to the configuration of a normal tricuspid orifice. The ring has one rectilinear segment corresponding to the septal leaflet and one long curved segment corresponding to the anterior and posterior leaflets. The ring is open at the anteroseptal commissure. The annuloplasty ring is provided on an integral template which holds the ring during the plication to the annulus. A feature of the Edwards MC3 Tricuspid annuloplasty ring is that the rigid template is designed not to interfere with the tying of sutures and contains a retrieval system during the removal process. After implantation, this rigid template is removed.

The model 1150 handle may be utilized to facilitate ease of suture placement and annuloplasty ring implantation. The snap-fit assembly of the handle and template/lanyard assembly allows for connecting and disconnecting of the two components.

The Carpentier-Edwards Physio annuloplasty ring is intended for the correction of mitral valve insufficiency, or mixed mitral insufficiency and stenosis, where treatment does not necessitate a replacement of the natural mitral valve.

The Carpentier-Edwards Physio annuloplasty ring, Model 4450 is constructed of Elgiloy bands separated by polyester film strips and has a sewing ring margin that consists of a layer of silicone rubber covered with a woven polyester cloth.

The mitral annuloplasty ring conforms to the configuration of a normal mitral annulus. It is kidney-shaped with one long curved segment corresponding to the posterior leaflet annulus. A rectilinear portion corresponds to the anterior leaflet annulus. Transverse colored threads indicate the anterior and posterior commissures.

The ring exhibits characteristics of differential flexibility. While retaining stiffness, the annuloplasty ring is also flexible in the portion corresponding to the anterior leaflet. The flexibility is increased in the posterior regions of the ring. Along the annular plane the ring is stable with a saddle-shaped curve for apposition to the aortic root.

The design is intended to provide support after annuloplasty surgery. The ring maintains a fixed maximum annular dimension to prevent excessive distension of the natural valve annulus while adapting to the dynamic motion of the mitral annulus throughout the cardiac cycle.

The holder, designed to facilitate ring implantation, is manufactured from an amorphous polymer. The annuloplasty ring is mounted on the holder with three retaining sutures.

The handle, Model 1150, may be utilized in conjunction with the holder to facilitate ease of suture placement and implantation. The middle section of the handle is malleable, allowing the handle to be adjusted (bent) in a configuration convenient for use. The handle is packaged separately. The snap assembly of the handle and holder allows for connecting and disconnecting the two components at appropriate times during the surgical procedure.

TransForm™ McCarthy Mitral Annuloplasty Ring (TF) is indicated for use in patients undergoing surgery for diseased or damaged mitral valves. The ring provides support for and restricts expansion of the mitral annulus.

The TransForm™ McCarthy Mitral Annuloplasty Ring is an implantable, semi-rigid annuloplasty ring for mitral valve repair with the stiffened portions at the anterior and posterior segments. The ring is flexible at the commissure regions to allow physiological movement of the annulus. Stiffener placement allows the ring to maintain its "D" saddle shape during systole and a flat planar "O" shape in diastole. The stiffeners consist of MP35N 0.71 mm diameter (polished and formed) alloy. An elastic silicone core and braided polyester fabric form the ring body. The TransForm™ Annuloplasty Ring has four green radial markers: two markers at the left and right trigones and two markers at the mid-anterior and mid-posterior. The ring conforms to the natural mitral annulus throughout the cardiac cycle. The interrupted stiffeners within the silicone core provide semi-rigid elastic flexibility. Elasticity of the "D" to "O" or circular transformation, accommodates remodeling of the annulus, while creating inward forces to maintain circular annular geometry against physical expansion. The size range of TransForm™ is from 24mm to 40mm with 2mm increments. Size refers to the internal CC diameter of the ring. Rings are intended to be implanted on the patient's mitral annulus to reduce and stabilize the annulus.

This FDA 510(k) clearance letter details the review of a new medical device, the TransForm™ McCarthy Mitral Annuloplasty Ring, for substantial equivalence to a predicate device.

Like their predicate devices, the subject MEMO 3D, MEMO 3D ReChord and MEMO 4D Semirigid Annuloplasty Rings are supplied as sterile, nonpyrogenic ring pre-mounted on disposable holders.

Both the predicate and subject devices are manufactured by embedding a superelastic metallic alloy inner core with medical grade silicone.

The resulting silicone sheath around the inner core is then encased within a tubular knitted fabric coated with a thin layer of turbostratic carbon (Carbofilm™). The fabric is then sewn along its length with a Carbofilm™ coated polyester thread.

Both the predicate and subject devices MEMO 3D ReChord and MEMO 4D Semirigid Annuloplasty Rings feature a fully removable system (i.e., the ReChord System) in the posterior curve of the annuloplasty ring, composed by a series of loops made by a single piece of yellow surgical thread retained in place by a single piece of blue surgical thread.

The MEMO 3D and MEMO 3D ReChord Annuloplasty Rings are manufactured in 8 different sizes, from 24 to 38 mm, with 2 mm increments.

The MEMO 4D Annuloplasty Ring is manufactured in 10 different sizes, from 24 to 42 mm, with 2 mm increments.

A complete set of accessories is available separately to properly size the annulus and implant the MEMO 3D, MEMO 3D ReChord and MEMO 4D annuloplasty ring.

The provided document is a 510(k) summary for the Memo 3D Semirigid Annuloplasty Ring, Memo 3D ReChord Semirigid Annuloplasty Ring, and Memo 4D Semirigid Annuloplasty Ring. This type of submission focuses on demonstrating substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria through a standalone study.

Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving device performance in the way a clinical study report would.

Specifically:

1. A table of acceptance criteria and the reported device performance: Not provided. The submission focuses on showing that changes in raw materials and manufacturing (alternative suppliers for PET fabric and suture thread, and a different sewing path) do not alter the fundamental characteristics or performance compared to the predicate devices.
2. Sample size used for the test set and the data provenance: Not applicable in the context of a 510(k) submission primarily relying on non-clinical testing for material and manufacturing changes.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
4. Adjudication method: Not applicable.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is an annuloplasty ring, not an AI-powered diagnostic tool.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable.
7. The type of ground truth used: Not applicable.
8. The sample size for the training set: Not applicable.
9. How the ground truth for the training set was established: Not applicable.

Summary of Non-Clinical Performance Data Provided (Section VII):

The submission relies on the following non-clinical performance data to demonstrate substantial equivalence:

• Biocompatibility testing
• Mechanical characterization of the PET fabric from the alternative supplier.
• Mechanical characterization of the PET suture thread from the alternative supplier and the alternative sewing path.
• Mechanical testing of the final device manufactured with the new suppliers' materials and sewing path.
• Quality control testing to evaluate the Carbofilm™ coating on the PET fabric and suture thread from the alternative suppliers.
• LAL test to evaluate endotoxin contamination on the new materials and final devices.

Clinical Performance Data (Section VIII):

The document explicitly states: "No clinical testing was conducted in support of the subject devices, as the indications for use are equivalent to those of their predicate devices (K071327, K142221, K180411). The non-clinical testing referred to in this submission supports the substantial equivalence of these devices."

Therefore, the approval is based on the substantial equivalence of the modified devices to already cleared predicate devices, supported by non-clinical testing to ensure that the changes in raw materials and manufacturing methods do not adversely affect the safety and effectiveness of the device.

The SimuPlus flexible annuloplasty ring and band are in patients undergoing surgery for diseased or damaged mitral valves. The band is indicated for the same use for tricuspid valves. The SimulPlus flexible annuloplasty ring and band provide support for the mitral annulus or tricuspid annulus (band only) and restrict expansion of the annulus.

The SimuForm semi-rigid annuloplasty rings are for use in patients undergoing surgery for diseased or damaged mitral valves. The SimuForm semi-rigid annuloplasty ring provides support for the mitral annulus and restricts expansion of the annulus.

The SimuPlus flexible annuloplasty ring (Model 7700FR) and band (Model 7700FB) consist of a flexible braided polyester fabric with a 3 mm cross-section. The ring or band may be implanted in the mitral annulus to stabilize the annulus following valve repair. The band may be implanted in the tricuspid annulus to stabilize the annulus following valve repair. The ring and band are marked at three points by colored sutures. Two markers correspond to the trigones (mitral valve) or septal commissures (tricuspid valve), and a central marker identifies the centerline of the ring or band. The individual ring or band size (26 mm to 42 mm increments) refers to the circumference between the green trigone markers on the ring or band. Silicone markers, impregnated with barium sulfate and tungsten, enable radiographic visualization. The ring and band are mounted to a holder to ease positioning and implantation.

The SimuPlus annuloplasty ring and band holder incorporates a chordal reference line to assist the surgeon during chordal repair procedures. A laterally stretched suture is present across the holder opening above the typical area of leaflet coaptation. This suture helps approximate the level of the annular plane. If the surgeon decides to include artificial chords in the valve repair, the chordal reference line may be useful when determining the level at which to tie the artificial chord knots. The chordal reference line does not require any additional steps to remove. It is removed with the holder after the retention sutures are cut.

The SimuForm semi-rigid annuloplasty ring (Model 7800RR) consists of a MP35N wire stiffener in the posterior segment, running from trigone to trigone. The ring stiffener is enclosed within a close-coiled MP35N spring that passes around the circumference of the annuloplasty ring. The spring is covered by a thin silicone sheath. Braided polyester fabric is used to cover and form the body of the ring. The ring has two green markers to indicate the anterior and posterior trigones. A green demarcation suture runs around the upper face of the ring. The individual ring size (24 mm to 40 mm in 2 mm increments) refers to the inner circumference between the green trigone markers on the ring. The internal spring and stiffener provide radiographic visualization around the circumference of the ring.

The SimuForm annuloplasty ring holder incorporates a chordal reference line to assist the surgeon during chordal repair procedures. A laterally stretched suture is present across the ring holder opening above the approximate area of leaflet coaptation. This suture helps approximate the level of the annular plane. If the surgeon decides to include artificial chords in the valve repair, the chordal reference line may be useful when determining the level at which to tie the artificial chords knots. The chordal reference line does not require any additional steps to remove. It is removed with the holder after the retention sutures are cut.

I am sorry, but based on the provided text, there is no information about acceptance criteria or a study proving that a device meets those criteria. The document is a 510(k) premarket notification for annuloplasty rings and bands, arguing their substantial equivalence to previously marketed predicate devices.

The key points from the document are:

• Device: SimuPlus Flexible Annuloplasty Ring, SimuPlus Flexible Annuloplasty Band, SimuForm Semi-Rigid Annuloplasty Ring.
• Purpose: To gain clearance for these devices by demonstrating they are "substantially equivalent" to predicate devices (Simulus Flexible Annuloplasty Ring and Band, Simulus Semi-Rigid Annuloplasty Ring).
• Changes:
  • SimuPlus (Flexible): Updates to product name, indications (minor phrasing changes), labeled size range (to align with industry sizing, no change to implant construction or dimensions), handle compatibility, and language for instructions for use (eIFU/paper IFU).
  • SimuForm (Semi-Rigid): Updates to product name, handle compatibility, and language for instructions for use (eIFU/paper IFU). No change to the implantable ring, its intended use, principles of operation, or size range.
• Conclusion: "The modifications to the Simulus devices do not impact the intended use or alter the fundamental scientific technology of the devices. There is no change to the implantable rings and bands. The SimuPlus and SimuForm rings and bands are therefore substantially equivalent to the currently marketed predicate devices."
• Performance Data: "Performance testing was not required to support labeling changes made to align with standard industry sizing." This explicitly states that performance testing was not done for this submission, as the changes were deemed not to affect fundamental performance.

Therefore, the requested information regarding acceptance criteria, device performance studies, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth types, and training set details cannot be extracted from this document. This document focuses solely on demonstrating substantial equivalence based on the nature of the changes made and comparison to predicate devices, rather than presenting new performance data against specific acceptance criteria.

The Physio Flex Annuloplasty Ring, model 5300, is indicated for the correction of mitral valve insufficiency, or mixed mitral insufficiency, where treatment does not necessitate replacement of the natural mitral valve.

The Physio Flex annuloplasty ring is a semi-rigid, open, mitral annuloplasty ring with an asymmetrical open anterior segment. The ring has an asymmetrical open anterior segment corresponding to the mitral annulus below the aorto-mitral curtain. The complete portion of the ring begins at the anterolateral commissure and extends beyond the posteromedial commissure and the posteromedial trigone into the anterior annulus. The ring design has a rectangular Nitinol core which enables different flexibilities in-plane and out-of-plane. The ring flexibility progressively increases in-plane from size 24 mm to 30 mm. It remains relatively constant from size 30 mm to 40 mm. For each ring size, the out-of-plane flexibility is greater than the in-plane flexibility. The ring also has a progressive saddle height with a complete posterior saddle and an open anterior saddle. The ratio of the saddle height to the A-P (antero-lateral to postero-medial) dimension progressively increases from size 24 mm to size 36 mm. It remains constant from size 36 mm to 40 mm. The Nitinol core is covered with a silicone sleeve and an external, knitted, polyester cloth. The sewing cuff is designed for ease of needle penetration and suture placement. A green circumferential suture line placed between the outer perimeter of the ring and the outer perimeter of the Nitinol core identifies the suture placement area. The ring has two commissure markers and a mid-posterior marker to facilitate orientation during implantation. The ring incorporates a holder with a proximal arm for connection to handle models 1150 and 1151. The holder arm is designed with a section made of stainless steel that can be bent to facilitate access and positioning of the ring on the valve annulus. The Physio Flex annuloplasty ring is available in sizes 24, 26, 28, 30, 32, 34, 36, 38 and 40 mm. The Physio Flex annuloplasty ring is designed to be used with sizer model 1252.

The provided text describes a 510(k) premarket notification for the "PHYSIO FLEX Annuloplasty Ring, model 5300". This document reports on the substantial equivalence of the new device to a predicate device, K083470 Carpentier-Edwards Physio II annuloplasty ring, model 5200.

The document discusses functional/safety testing performed to support substantial equivalence, but it does not provide specific acceptance criteria or an analytical study involving human readers or AI-assistance. The tests mentioned are device-specific and relate to its physical properties and biocompatibility.

Therefore, most of the requested information cannot be extracted from the provided text as it is focused on a medical device (annuloplasty ring) and its physical performance, not on a diagnostic algorithm or image analysis tool.

Here's a breakdown of what can and cannot be answered based on the provided text:

1. A table of acceptance criteria and the reported device performance

The document lists "Ring parachuting, Holder removal, Fatigue Life Analysis, Magnetic Resonance, Corrosion Resistance, Biocompatibility" as performance testing areas. However, it does not provide specific numerical acceptance criteria or the reported device performance for these tests. It only states that these data "demonstrate the device is substantially equivalent to the predicate."

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the document. The text mentions "representative samples of the devices underwent testing," but does not specify the sample size or data provenance.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This is not applicable and not provided. The device is a physical annuloplasty ring, not a diagnostic tool requiring expert interpretation for ground truth.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This is not applicable and not provided. As above, the testing described is for physical device performance, not for diagnostic accuracy requiring adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This is not applicable and not provided. The document describes a physical medical device (annuloplasty ring), not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This is not applicable and not provided. The document is about a physical medical device, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

This is not applicable. The "ground truth" for this device would be its physical and biocompatible properties meeting engineering specifications, rather than a clinical diagnosis.

8. The sample size for the training set

This is not applicable and not provided. As this is a physical device and not an AI algorithm, there is no "training set."

9. How the ground truth for the training set was established

This is not applicable and not provided.

In summary, the provided text primarily focuses on establishing substantial equivalence for a physical medical device. It does not contain the detailed information about acceptance criteria or specific study methodologies that would be relevant for a diagnostic or AI-powered medical device.
