Abstract: A vascular clip for use in end-to-side anastomoses having a handle connected to a lower ring and an upper ring. The handle includes a resilient element biasing the two rings together so that the rings are closely juxtaposed when the clip is closed. The respective facing surfaces of each of the rings may be provided with a rough surface. A graft vessel or an artificial aneurysm may be sutured to the lower ring. The graft vessel or artificial aneurysm may be autologous or heterologous material or may be made of synthetic material. The handle may fit into a clip applier that facilitates the application of the clip. The handle and the clip applier may be of different shapes depending on the various applications of the clip.

The rings may also have different shapes and sizes to accommodate different kinds of anastomoses and different vessels of all sizes in all parts and cavities of the human or animal body.

Abstract: A device for creating an end-to-side anastomosis between a graft vessel and a recipient vessel having an extravascular member, such as an upper ring, an intravascular member, such as a lower ring, and means to fix the intravascular member in the recipient vessel, such as a handle with a resilient element biasing the extravascular member and the intravascular member together. A graft vessel is attached to the intravascular member around an edge of an opening in the intravascular member. Other means than a biasing resilient element may be employed to fix the intravascular member in the recipient vessel which do not require an extravascular member, such as expandable cylinders. In other embodiments, means may be employed to insert the intravascular member into the recipient vessel such as delivery systems that open an arteriotomy while simultaneously delivering the intravascular member into the recipient vessel.

Abstract: An apparatus and method for microsurgical training using cadaveric anatomy with filling of the vascular system by fluids under pressure to simulate the appearance and function of live surgery. One or more arteries on the specimen of cadaveric anatomy are cannulated and connected to an arterial reservoir having a flexible container holding an arterial fluid simulating the appearance of blood circulating in the arteries of the living organism from which the cadaveric anatomy is derived. Suitable static pressure simulating the arterial pressure appropriate to that of the living organism is applied to the air in an air-tight space surrounding the flexible container in the arterial reservoir. A pulsating machine provides air pulsations to the space surrounding the flexible fluid container to simulate the normal pulsations of the arterial system.
