The device description and performance summary focus on a mechanical fastener and delivery tool for surgical occlusion, with no mention of AI/ML or related technologies.
Yes.
The device is designed to occlude the left atrial appendage, which is a therapeutic intervention, as evidenced by the "Intended Use" and "Summary of Performance Studies" sections discussing its effectiveness in achieving complete occlusion and its use in treating patients undergoing cardiac surgery.
No
The device is an implantable system designed for the occlusion of the left atrial appendage, not for diagnosing a condition. Its purpose is therapeutic.
No
The device description clearly states that the TigerPaw System consists of an implantable Fastener and a hand-held disposable Delivery Tool, which are physical hardware components.
Based on the provided information, the TigerPaw® System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- TigerPaw® System Function: The TigerPaw® System is an implantable device and a delivery tool used to physically occlude the left atrial appendage within the patient's body during open cardiac surgery. It is a surgical tool and implant, not a device that analyzes biological samples.
- Intended Use: The intended use clearly states it's for "occlusion of the left atrial appendage, under direct visualization, in conjunction with other open cardiac surgical procedures." This describes a surgical intervention, not a diagnostic test.
Therefore, the TigerPaw® System falls under the category of a surgical device or implant, not an IVD.
N/A
Intended Use / Indications for Use
The TigerPaw® System is indicated for the occlusion of the left atrial appendage, under direct visualization, in conjunction with other open cardiac surgical procedures.
Direct visualization, in this context, requires that the surgeon is able to see the heart directly, without assistance from a camera, endoscope, or any other viewing technology. This includes procedures performed by sternotomy (full or partial) as well as thoracotomy (single or multiple).

Device Description
The TigerPaw System consists of an implantable Fastener and Delivery Tool designed for occlusion of the left atrial appendage, under direct visualization, in conjunction with other open cardiac surgical procedures. The Fastener is composed of linearly spaced connectors overmolded with a soft silicone. The spacing between the connectors along with the silicone gives the Fastener an ability to conform to the anatomy and completely exclude the LAA. The TigerPaw® System also includes a hand-held disposable Delivery Tool. The Delivery Tool consists of a pistol grip handle with triggers that when actuated close jaws that in turn mate the two sides of the permanently implanted Fastener together.

Summary of Performance Studies
Extensive bench, animal, and cadaver evaluations were performed on the TigerPaw System. This testing consisted of in vitro bench testing, including connector tensile testing and pressure leak testing of fasteners; in vivo animal evaluation composed of a total of six acute canine and six chronic canine survived for six months with corresponding histopathology; and in situ cadaver evaluation comprising 14 specimens with varying disease history including gross pathology. Finally, a 60 patient clinical study was conducted.
Clinical study: This study was conducted to assess the safety and effectiveness of surgical Left Atrial Appendage (LAA) occlusion, using the LAAx, Inc. TigerPaw System (delivery system and implant/Fastener), as a concomitant procedure to other open chest cardiac surgery procedures including valve repair / replacement, coronary artery bypass grafting (CABG), and cardiac ablation procedures. The primary safety outcome was the rate of device related adverse (AE) and serious adverse events (SAE) assessed peri-operatively, and at 30 days post procedure. The primary effectiveness outcome was the percentage of patients with complete occlusion of the LAA assessed peri-operatively, both visually (implant/Fastener applied fully across the LAA Os) and via Transesophageal Echocardiography (TEE), and at 90 days post procedure also using TEE. Secondary safety endpoints included Major Adverse Cardiac Event (MACE) rates. Secondary effectiveness endpoints included the assessment of the size of residual LAA cavity remaining after application of the TigerPaw® System compared with a pre-defined target (≤ 6 mm).
Key Metrics
There were no unanticipated adverse events (AE) with one minor device-related tissue tear repaired with suture. Complete Left Atrial Appendage (LAA) occlusion was visually confirmed in each of the 60 treated patients and confirmed by Transesophageal Echocardiography (TEE) in 56 patients with one patient requiring adjunctive use of suture to achieve LAA closure. There were zero incidences of bleeding or leakage from the area of the device footprint. Fifty-four out of 54 evaluable patients followed up at the final 90 day period were confirmed to have complete LAA occlusion via TEE with zero leaks or communication between the LAA and LA and no late device-related AEs.

Comparison to Predicate Device(s):
The design of the TigerPaw® System is similar to the USGI device in that they are devices designed to place titanium or stainless steel staples in various types of tissue. The TigerPaw® System is similar to the Synovis predicate in they both use a non-absorbable material to reinforce suture-lines and staple-lines. All devices are packaged sterile and are for single patient use. Further, the TigerPaw® System and the predicate devices have the same or similar intended use.
Device Evaluation:
Extensive bench, animal, and cadaver evaluations were performed on the TigerPaw System. This testing consisted of in vitro bench testing, including connector tensile testing and pressure leak testing of fasteners; in vivo animal evaluation composed of a total of six acute canine and six chronic canine survived for six months with corresponding histopathology; and in situ cadaver evaluation comprising 14 specimens with varying disease history including gross pathology.
