GEM™ BIOVER disposable microvascular clamps are instruments which are used for all microsurgical procedures. They are used to occlude vessels during anastomosis, which is necessary as a result of vessel damage or thrombosis.

The GEM™ Biover Microvascular Clamps (Clamps) are arterial and venous clamps in both single and double clamp configurations, available in varying sizes. The clamps are sterile, disposable clamps for single use. The clamps are used in microsurgery, plastic surgery, and hand surgery for the temporary occlusion of blood vessels during an anastomosis. The clamps are available for arteries and veins. The clamping force is higher for the arterial clamps than for the veinous clamps. The clamps are identified by a product reference code and by the color of the clamp. The clamps for veins are green, and the clamps for arteries are yellow. The clamps are packaged individually in two Tyvek pouches (double pouched). The devices in the Tyvek pouches are gamma sterilized and are placed in cartons of 10. The clamps are used once and are disposed of after use.

The FLOW COUPLER Device is a single use, implantable device that is intended to be used in the end-to-end anastomosis of veins and arteries normally encountered in microsurgical and vascular reconstructive procedures. The FLOW COUPLER Device includes a pair of permanently implanted rings which secure the anastomosis and a removable Doppler probe that is press-fit onto one of the rings. When the FLOW COUPLER Device is used in conjunction with the FLOW COUPLER Monitor, the FLOW COUPLER System is intended to detect blood flow and confirm vessel patency intra-operatively and post-operatively at the anastomotic site. Post-operatively, blood flow can be detected on an as needed basis for up to 7 days. The FLOW COUPLER Doppler probe is not intended to be a permanent implant and should be removed 3 to 14 days post-operatively.

The GEM FLOW COUPLER System is designed for the detection of blood flow in vessels. The GEM FLOW COUPLER System consists of components as described below: 1. FLOW COUPLER Device (Product Code MVR) - single-use implantable rings used to secure anastomosis of small vessels. This includes a 20MHz ultrasonic Doppler transducer (probe) which attaches to one of the FLOW COUPLER rings, and an external lead. 2. FLOW COUPLER Monitor (Product Code DPW) - portable monitor that provides the audible output of the FLOW COUPLER Device's pulsed Doppler ultrasound signal. A varying audible signal is produced when the FLOW COUPLER Device (probe) detects flow.

The Microvascular Anastomotic COUPLER is to be used in the anastomosis of veins and arteries normally encountered in microsurgical and vascular reconstructive procedures.

The device is a sterile (gamma irradiation), single-use, implantable pair of rings molded out of high density polyethylene with six stainless steel pins on each of the ring. A probe-holder feature is molded on each of the paired rings to be a point of attachment for a sensor/probe at the site of anastomosis.
