Intended Use
The Tigertriever Revascularization Device is intended to restore blood flow by removing thrombus from a large intracranial vessel in patients experiencing ischemic stroke within 8 hours of symptom onset. Patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA), or who fail IV t-PA therapy, are candidates for treatment.
Device Description
The Tigertriever 13 device is a stentriever that is comprised of an adjustable nitinol braided mesh, stainless steel shaft, nitinol core wire and a handle. The shaft connects the mesh and the handle by the core wire that runs inside the shaft from the distal end of the slider activation element in the handle. The mesh is expanded when the physician pulls the slider, since the wires of the mesh are completely radiopaque, the physician sees the mesh under fluoroscopy and controls it until it conforms to the vessel diameter. The design of the wire mesh is optimized to penetrate the clot and encapsulate it during retrieval. The Tigertriever 13 Revascularization Device is supplied sterile and is intended for single-use only by physicians trained in neuro-interventional catheterization and the treatment of ischemic stroke.
More Information

No
The description focuses on the mechanical design and function of a stentriever device for clot removal, with no mention of AI or ML capabilities.

Yes
The device is intended to treat a medical condition (ischemic stroke) by removing thrombus, which directly addresses disease and aims to restore normal physiological function (blood flow).

No

This device is a therapeutic revascularization device (stentriever) used to remove blood clots in patients experiencing ischemic stroke. Its purpose is to restore blood flow, not to diagnose a condition.

No

The device description clearly outlines a physical, hardware-based medical device (stentriever) comprised of materials like nitinol, stainless steel, and a handle, intended for mechanical thrombus removal. It is not a software-only device.

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

Here's why:

  • Intended Use: The intended use is to "restore blood flow by removing thrombus from a large intracranial vessel." This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
  • Device Description: The device is a "stentriever" designed to physically interact with and remove a clot within a blood vessel. This is a medical device used for treatment.
  • Lack of Diagnostic Elements: There is no mention of the device analyzing biological samples (blood, tissue, etc.) or providing information about a patient's health status based on such analysis.
  • Performance Studies: The performance studies focus on the device's mechanical function, safety, and ability to remove clots in a model and animal setting. They do not involve diagnostic metrics like sensitivity, specificity, or AUC, which are typical for IVDs.

In summary, the Tigertriever Revascularization Device is a therapeutic medical device used for the treatment of ischemic stroke, not a diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-Clinical Performance Data:

  • Biocompatibility: Based on Comaneci Embolization Assist Device (DEN170064) due to shared manufacturing. Tests included Cytotoxicity, Irritation, Sensitization, Hemocompatibility, Pyrogenicity, Acute Systemic Toxicity, and in vivo thrombogenicity (for Tigertriever model). All tests showed acceptable results (non-cytotoxic, non-irritant, no sensitization, pass hemocompatibility, non-pyrogenic, non-toxic, and thrombogenicity comparable to predicate).
  • Sterilization and Shelf life: Sterilized by 100% Ethylene Oxide, supports 2.5-year shelf life.
  • Bench Tests:
    • Simulated use test: Performed in an in vitro tortuous path anatomical model. The device effectively retrieved clot and restored flow.
    • Radial force: Measured within 1.5mm and 2.5mm diameters, comparable to predicate device.
    • Durability: No damage after delivery and withdrawal testing; established acceptable performance for 3 passes.
    • Delivery, deployment and retrieval: Demonstrated acceptable performance in an in vitro tortuous path anatomical model.
    • Torque strength: Withstood 5 rotations without damage.
    • Dimensions test: Conformance to specifications, minor differences from predicate do not affect performance/safety/effectiveness.
    • Tip flexibility: Met acceptance criteria.
    • Kink resistance: Demonstrated acceptable performance under simulated anatomic tortuosity.
    • Tensile test: Met acceptance criteria based on ISO 10555-1.
    • Particulates: Particulate generation similar to predicate device.
    • Austenite Finish (Af) Temperature: Met acceptance criteria.
    • Coating integrity assessment: No damage to PTFE core wire coating observed after simulated use (performed with Comaneci device).
    • Corrosion: No corrosion observed (performed with Comaneci device), met acceptance criteria based on ISO 10555-1.

Pre-Clinical Animal Testing Data:

  • Study Type: Two pre-clinical studies (sub-acute and 30-day chronic time points) in a swine model.
  • Sample Size: Not explicitly stated, but "animals were assessed" and "in each tested vessel three passes were performed."
  • Key Results: Full reperfusion demonstrated in all procedures. No evidence of vessel damage (dissection, perforation, clot formation) related to device deployment. Histopathological assessment considered acceptable. Device demonstrated acceptable safety and clot retrieval performance.

Device Description

The Tigertriever 13 device is a stentriever that is comprised of an adjustable nitinol braided mesh, stainless steel shaft, nitinol core wire and a handle. The shaft connects the mesh and the handle by the core wire that runs inside the shaft from the distal end of the slider activation element in the handle. The mesh is expanded when the physician pulls the slider, since the wires of the mesh are completely radiopaque, the physician sees the mesh under fluoroscopy and controls it until it conforms to the vessel diameter. The design of the wire mesh is optimized to penetrate the clot and encapsulate it during retrieval. The Tigertriever 13 Revascularization Device is supplied sterile and is intended for single-use only by physicians trained in neuro-interventional catheterization and the treatment of ischemic stroke.

Comparison of Technological Characteristics with the Predicate Device

The Tigertriever 13 Revascularization Device is substantially equivalent to the Tigertriever 17 Revascularization Device (model: TRPP7166) previously cleared as part of K203592. The two devices have the same indications for use and principles of operation, and similar technological characteristics. There are minor differences in dimensions between the two device models; however, they provide physicians with a slightly broader range of lengths and diameters to accommodate the range of large vessel occlusion (LVO) dimensions. This difference in dimensions does not raise new questions of safety or effectiveness. A summary of the technological characteristics of the Tigertriever 13 Revascularization Device in comparison to those of the predicate device is presented in the table below.

Non-Clinical Performance Data

As part of demonstrating safety and effectiveness of the device and in showing substantial equivalence to the predicate device, Rapid Medical Ltd. completed a number of non-clinical performance tests. The device meets all the requirements of overall design, sterilization, and biocompatibility. Testing results confirm that the design output meets the design specification for the device.

Biocompatibility

Biocompatibility of the Tigertriever 13 was based on the biocompatibility testing data for the Comaneci Embolization Assist Device (DEN170064). The two devices share the same manufacturing process and same manufacturing environment. In addition, the two devices are intended to be used in the same anatomical locations and are identical in terms of frequency and duration of exposure. Biocompatibility testing was completed for Comaneci device and consisted of the following tests: Cytotoxicity, Irritation (Intracutaeous Reactivity), Sensitization, Hemocompatibility, Pyrogenicity, Acute Systemic and Toxicity Testing. In addition, in vivo thrombogenicity was performed for the Tigertriever model. Results of the biocompatibility testing indicate that Tigertriever 13 Revascularization Device is biocompatible and is substantially equivalent for its intended use.
