Device Description
Major components of the SUPER SHEATH (PROPOSED) are a sheath and a dilator. In addition, a guidewire is covered under this premarket notification. The guidewire is placed in the gudiewire case including inserter. The sheath for the SUPER SHEATH (PROPOSED) is named as the SUPER SHEATH (PROPOSED) Introducer Sheath and is available in 4F- 9F diameters and in lengths ranging from 7 to 25 cm. Some types of sheaths have radiopaque markers. The SUPER SHEATH (PROPOSED) are provided sterile and are intended for one procedure use only. The one-piece construction of the sheath shaft and hub allows smooth passage of concomitantly interventional medical devices. The sheath shaft and hub are made of Ethylene Tetrafluoro ethylene (ETFE) and polyamide. The hubs, color-coded by French size, contain a hemostatic valve to minimize blood leakage during a procedure. A side tube equipped with a three-way stopcock is attached to the sheath hub. The side tube extension may be used for fluid and medication administration, as well as blood sampling. Some types of sheaths contain a marker band that is embedded in the shaft approximately 2.0 mm from the distal tip. The dilator is an open tapered plastic tube with an integral luer hub for guidewire insertion. The dilator is inserted into the introducer sheath. The dilator is longer than the sheath with a rounded tapered distal tip. The dilator facilitates and supports the entry of the sheath into the patient's vasculature. Once the sheath is in place the dilator is removed. There are two different dilator distal tip sizes, 0.038" and 0.035" guidewire compatible. The 4F dilators are only available with a 0.035" guidewire lumen dilator. The 5-9F dilators are available with a 0.035" or 0.038" guidewire lumen. The 4bes are made from Polypropylene (PP). The 9F dilator tubes are made of Fluorinated Ethylene Propylene (FEP). The dilator tubes are attached to the inner hub with a metal bush. The sheath hub and the dilator hub lock using a rotating motion. The SUPER SHEATH (PROPOSED) has a polypropylene suture wing which is color coded by French size. The suture wing is a small projection near the hub with a hole in it for correct placement of the sheath using sutures. The uncoated guidewire is made of a stainless steel coil wrapped tightly around an inner mandrel that tapers at the distal tip. The flexible tip is J-shaped available in diameters of 0.035" and 0.038". The guidewire, with inserter, is available in 45 cm and 80 cm lengths. The inserter is used strictly for guiding the guidewire into a cannula or introducer.
More Information

Not Found

No
The device description focuses on the physical components and materials of a sheath, dilator, and guidewire, with no mention of software, algorithms, or data processing that would indicate AI/ML. The "Mentions AI, DNN, or ML" section is explicitly marked as "Not Found".

No.
The device is described as an introducer sheath and dilator, indicated for the "introduction of diagnostic and interventional devices" into the vasculature. Its primary role is to facilitate the insertion of other devices, not to provide therapy itself. While it enables therapeutic procedures, it is not inherently therapeutic.

No

The device is an introducer sheath, guidewire, and dilator used to facilitate the introduction of other diagnostic and interventional devices into the vasculature. It does not perform diagnostic functions itself.

No

The device description clearly outlines physical components such as a sheath, dilator, and guidewire, made of materials like ETFE, polyamide, polypropylene, and FEP. It also mentions physical features like radiopaque markers, hubs, side tubes, and suture wings. There is no mention of software as a component or function of the device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for the "introduction of diagnostic and interventional devices inserted into the peripheral and coronary vasculature." This describes a device used in vivo (within the body) to facilitate other procedures, not a device used in vitro (outside the body) to examine specimens from the body.
  • Device Description: The description details a sheath, dilator, and guidewire designed for insertion into blood vessels. These are all components used directly in a medical procedure on a patient.
  • Lack of IVD Characteristics: There is no mention of analyzing biological specimens (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The device's function is purely mechanical and procedural.

Therefore, the SUPER SHEATH (PROPOSED) is a medical device used for vascular access, not an in vitro diagnostic device.

Since the same name as predicate device is used, the new device under application is hereinafter called "the SUPER SHEATH (PROPOSED)" and the predicate devices are called "the SUPER SHEATH (K052557)" and "the 3.3F SUPER SHEATH (K121504)", respectively, for convenience of discussion in this application.

We are claiming substantial equivalence to product codes DRE and DYB.

f. Description of the device

Major components of the SUPER SHEATH (PROPOSED) are a sheath and a dilator. In addition, a guidewire is covered under this premarket notification. The guidewire is placed in the gudiewire case including inserter.

The sheath for the SUPER SHEATH (PROPOSED) is named as the SUPER SHEATH (PROPOSED) Introducer Sheath and is available in 4F- 9F diameters and in lengths ranging from 7 to 25 cm. Some types of sheaths have radiopaque markers. The SUPER SHEATH (PROPOSED) are provided sterile and are intended for one procedure use only.

The one-piece construction of the sheath shaft and hub allows smooth passage of concomitantly interventional medical devices. The sheath shaft and hub are made of Ethylene Tetrafluoro ethylene (ETFE) and polyamide.

The hubs, color-coded by French size, contain a hemostatic valve to minimize blood leakage during a procedure. A side tube equipped with a three-way stopcock is attached to the sheath hub. The side tube extension may be used for fluid and medication administration, as well as blood sampling. Some types of sheaths contain a marker band that is embedded in the shaft approximately 2.0 mm from the distal tip.

The dilator is an open tapered plastic tube with an integral luer hub for guidewire insertion. The dilator is inserted into the introducer sheath. The dilator is longer than the sheath with a rounded tapered distal tip. The dilator facilitates and supports the entry of the sheath into the patient's vasculature. Once the sheath is in place the dilator is removed. There are two different dilator distal tip sizes, 0.038" and 0.035" guidewire compatible. The 4F dilators are only available with a 0.035" guidewire lumen dilator. The 5-9F dilators are available with a

0.035" or 0.038" guidewire lumen. The 4bes are made from Polypropylene (PP). The 9F dilator tubes are made of Fluorinated Ethylene Propylene (FEP). The dilator tubes are attached to the inner hub with a metal bush. The sheath hub and the dilator hub lock using a rotating motion.

The SUPER SHEATH (PROPOSED) has a polypropylene suture wing which is color coded by French size. The suture wing is a small projection near the hub with a hole in it for correct placement of the sheath using sutures.

The uncoated guidewire is made of a stainless steel coil wrapped tightly around an inner mandrel that tapers at the distal tip. The flexible tip is J-shaped available in diameters of 0.035" and 0.038". The guidewire, with inserter, is available in 45 cm and 80 cm lengths. The inserter is used strictly for guiding the guidewire into a cannula or introducer.

Note*: There are two different dilator distal tip sizes, 0.038" and 0.035" guidewire compatible. Note that the 4F dilators are only available with a 0.035"guidewire lumen dilator. The 5-9F dilators are available with a 0.035" or 0.038" guidewire lumen.

SUPER SHEATH (K052557) referenced regulation number 870.1310 and product code DRE. However 3.3F SUPER SHEATH (K121504) for additional sizes utilized regulation number 870.1340 and product code DYB, which are referenced by the current submission. Citation of 870.1340 /DYB is presumably the most current regulatory practice as evidenced by 3.3F SUPER SHEATH (K121504).

Regarding the main body of the SUPER SHEATH (PROPOSED), major components are a sheath and a dilator. In addition, a guidewire is covered under this premarket notification. The guidewire is placed in the Gudiewire case including inserter. The only difference from the SUPER SHEATH (K052557) is the modifications of material change of the sheath shaft.

In order to evaluate any effects of the above changes on safety and effectiveness for the main body, biocompatibility testing and bench testing including shelf-life testing were performed.-Biocompatibility testing demonstrated that the SUPER SHEATH (PROPOSED) does

Regarding packaging of the SUPER SHEATH (PROPOSED), packaging integrity test and sterility test demonstrates the packaging works as a sterile barrier for the SUPER SHEATH (PROPOSED) and is substantial equivalent to the packaging of the 3.3F SUPER SHEATH (K121504).

Based on above, we concluded that the modification did not raise any new safety or effectiveness concerns compared to the SUPER SHEATH (K052557) for main body and the 3.3F SUPER SHEATH (K121504) for packaging.
