Abstract

A cardiovascular tourniquet and surgical method of applying the same is disclosed for use in support of a cannula operatively inserted into a blood vessel with a purse string suture. Ends of the suture are drawn to close the blood vessel around the cannula and then passed through a tubular member having integrally formed rib-like sections spaced apart along its length. The tubular member is firmly secured alongside the cannula by at least a pair of spring clips fastened about the cannula and adapted to grasp the tubular member between its rib-like sections. An integral cap is further provided at one end of the tubular member for releasably clamping the suture ends drawn therethrough thereby preventing the suture from loosening during subsequent procedures and maintaining proper disposition of the cannula.
