The Heli-FX EndoAnchor System is intended to provide fixation and sealing between endovascular aortic grafts and the native artery. The Heli-FX EndoAnchor system is indicated for use in patients whose endovascular grafts have exhibited migration or endoleak, or are at risk of such complications, in whom augmented radial fixation and/or sealing is required to regain or maintain adequate aneurysm exclusion.

The EndoAnchor may be implanted at the initial endograft placement, or during a secondary (i.e., repair) procedure.

The Heli-FXTM EndoAnchor™ Systems are each comprised of the respective Heli-FX Applier with EndoAnchor Cassette, containing ten EndoAnchor implants; the respective Heli-FX Guides; and the Ancillary EndoAnchor Cassette, containing five EndoAnchor implants.

The Heli-FX EndoAnchor System comprises the EndoAnchor implant, an intravascularly-applied suture, supplied with the Heli-FX Applier in a Cassette containing ten (10) EndoAnchor implants, or separately in an Ancillary Cassette containing five (5) EndoAnchor implants; the Heli-FX Applier, a catheter-based device for placement of the EndoAnchor; and the Heli-FX Guide, a deflectable sheath to position the Applier.

The EndoAnchor is an endovascularly-placed suture designed to attach aortic endografts to the native vessel wall. The EndoAnchor is manufactured from medical-grade nickel-cobalt wire and is wound in a helical shape. The leading end is sharpened to a conical point to act as an integral needle facilitating atraumatic deployment through the graft material and vessel wall. The proximal end of the EndoAnchor includes a diagonal crossbar, which functions as a suture anchor designed to prevent over penetration of the EndoAnchor. Ten (10) EndoAnchor implants are prepackaged into a cassette, which is supplied with the Heli-FX Applier. The cassette is designed to facilitate easy and accurate loading of the EndoAnchor into the Applier catheter. EndoAnchor implants are also supplied separately in an Ancillary Cassette containing five (5) additional EndoAnchor implants.

The Heli-FX Applier is designed to implant the EndoAnchor. The Applier implants one EndoAnchor at a time, and can be used to implant multiple EndoAnchor implants in a single patient. The Applier is designed for use with the Heli-FX Guide. The Applier is a 12Fr (OD) catheter with an integrated control handle. Two Applier lengths are available for anchoring in different regions of the aorta.

The Heli-FX Guide is a sterile, single use, disposable device designed to direct the Heli-FX Applier to the desired location for EndoAnchor implantation. The device is compatible with a 0.035" Guide wire. The Heli-FX Guide consists of a 12 Fr-compatible (inner diameter) Guide sheath with integrated control handle, and a matching 12 Fr OD obturator. Deflection of the distal tip of the catheter is accomplished by rotating the Control Knob located on the control handle. The Guide is available in both 62cm (16Fr OD) and 90cm (18Fr OD) working lengths. Multiple deflectable tip lengths are available to accommodate a range of aortic diameters. The Obturator is used during vessel access and is designed to follow the Guide wire and provide access through tortuous vasculature.

This document is a 510(k) summary for the Heli-FX EndoAnchor System, which is an endovascular suturing system. The purpose of this 510(k) submission is to demonstrate substantial equivalence to a previously cleared device (K171427) by stating that the Heli-FX EndoAnchor System is compatible with the Valiant Navion Stent Graft System.

Based on the provided text, the document states that "no new testing with the Valiant Navion Stent Graft System was needed" because "Adequate rationale was provided to support the compatibility of these systems based on the previously provided testing with the endografts that are currently listed as compatible with the Heli-FX EndoAnchor System in its IFU."

Therefore, the acceptance criteria and study information would refer to the previous submission (K171427) or prior testing, which is not detailed in this specific document. This document only describes the device and its intended use, and then asserts substantial equivalence based on prior testing and rationale.

Since the document explicitly states "no new testing," it does not contain the information requested in your prompt regarding acceptance criteria, device performance, sample sizes, expert details, adjudication methods, MRMC studies, standalone performance, or ground truth for a new study.

To provide the requested information, the details from the original 510(k) submission (K171427) would be required.
