Possis Medical, Inc's GuardDOG(R) Occlusion System

Possis Medical, Inc. has introduced the GuardDOG(R) Occlusion System for use during the treatment of peripheral vascular disease. The GuardDOG System enables physicians to quickly and effectively manage local blood flow while employing interventional techniques and devices to treat vascular disease.

The GuardDOG Occlusion System is the first guidewire-based occlusion device designed and marketed with the specific challenges of the peripheral vasculature in mind. It features a 0.035" diameter guidewire, preferred for peripheral interventions, and a soft, compliant, CO2-filled balloon providing quick inflation and deflation.

The GuardDOG Inflation device is used to inflate the occlusion balloon and seal the guide wire once it is in position. The GuardDOG Inflation device is a disposable C02 delivery device with two Possis Special 510k for the GuardDOG Occlusion System integrated syringes and a gauge. One syringe contains 20cc of C02 and the second syringe is used to evacuate air from the Occlusion Guide Wire. The gauge is used to measure pressure of C02 delivered. The GuardDOG Inflation device is packaged in Tyvek pouch for sterilization and then into a sealable can to maintain the C02 environment.

GuardDOG is a specially designed family of guidewires featuring a soft, compliant balloon at the distal tip. By inflating the balloon, the operator can temporarily and selectively occlude blood flow during interventional treatment.

Designed to facilitate delivery of over-the-wire interventional tools, the GuardDOG System can be delivered through 0.038" diagnostic catheters to the treatment site. The GuardDOG System can be inflated, deflated and positioned up to three times during a single procedure, improving efficiencies in both routine and complicated procedures. These GuardDOG System features enable physicians to manage blood flow and achieve desired occlusion in peripheral vessels 3-6mm in size.
