The device description and performance studies focus on the mechanical properties and biocompatibility of a physical connector, with no mention of AI or ML.
No
The device is a connector for attaching a vascular graft, which serves as a component in a surgical procedure, rather than directly providing a therapeutic effect itself such as treating an illness or improving a medical condition.
No
The device is a vascular ring connector used to attach a vascular graft to native tissue, serving as a connector for surgical procedures rather than for diagnosing any condition.
No
The device description explicitly states the device is made of biocompatible titanium alloy and includes a braided ligature tape, indicating it is a physical medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to connect a vascular graft to native tissue during surgery. This is a surgical device used in vivo (within the body) for a structural purpose.
- Device Description: The description details a physical connector made of titanium alloy and ligature tape, designed for mechanical attachment.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (blood, tissue, etc.) to provide diagnostic information about a patient's health status. IVDs are used to perform tests in vitro (outside the body) on biological specimens.
The device is clearly a surgical implant/connector, not a diagnostic tool.

Intended Use / Indications for Use
The VASORING* VRC Vascular Ring Connector is indicated for use as a connector for attaching a vascular graft to native tissue where conditions preclude a conventional end-to-end sutured anastomosis.

Device Description
The vascular ring connector is made of biocompatible titanium alloy. Placed in the vascular prosthesis to form a Graft-Connector Unit, it can be used as an intraluminal graft. The braided ligature tape (Ethicon® Nylon Tape) is for tying the ring connector from outside of the blood vessel to provide sutureless anastomosis that is time-saving. There are two grooves on the outer surface of the connector: the narrow groove is for suture fixation between the connector and the vascular prosthesis; and the wider groove is for ligature fixation between the connector and the blood vessel. The titanium alloy allows the ring connector to be of thin-wall design which gives larger inner diameter while maintaining adequate mechanical strength at the anastomotic sites.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench testing was performed to ensure that VASORING* VRC will meet all functional and performance requirements for its intended use. The titanium alloy connector was also tested for material biocompatibility per ISO 10993 guidelines. Two pre-clinical animal studies were performed to investigate the thrombogenicity phenomena; a 4-hours study to assess immediate impact of using the VRC for anastomoses, and the other was a 20-week observation of the test animals. All bench tests, biocompatibility tests, and thrombogenicity studies demonstrated satisfactory performance of the VASORING* VRC connectors.

§ 870.3450 Vascular graft prosthesis.
(a)
Identification. A vascular graft prosthesis is an implanted device intended to repair, replace, or bypass sections of native or artificial vessels, excluding coronary or cerebral vasculature, and to provide vascular access. It is commonly constructed of materials such as polyethylene terephthalate and polytetrafluoroethylene, and it may be coated with a biological coating, such as albumin or collagen, or a synthetic coating, such as silicone. The graft structure itself is not made of materials of animal origin, including human umbilical cords.(b)
Classification. Class II (special controls). The special control for this device is the FDA guidance document entitled “Guidance Document for Vascular Prostheses 510(k) Submissions.”

The VASORING* VRC Vascular Ring Connector is indicated for use as a connector for attaching a vascular graft to native tissue where conditions preclude a conventional end-to-end sutured anastomosis.
6. Technological Characteristics
The VASORING* VRC Vascular Ring Connector is identical to the Meadox Intra-Aortic Graft polyester connector with respect to intended use. The titanium alloy ring is of cylindrical shape with an outside diameter ranging from 6mm to 30mm for use with various sizes of aorta to achieve proper anastomoses.
7. Performance Summary
Bench testing was performed to ensure that VASORING* VRC will meet all functional and performance requirements for its intended use. The titanium alloy connector was also tested for material biocompatibility per ISO 10993 guidelines. Two pre-clinical animal studies were performed to investigate the thrombogenicity phenomena; a 4-hours study to assess immediate impact of using the VRC for anastomoses, and the other was a 20-week observation of the test animals.
