A releasable, surgical clamp (10) for insertion through a surgical introducer sheath (11) and into a cavity (12) of a patient (13) during a minimally invasive surgical procedure. The releasable clamp comprises a continuous wire (39) that is shaped for insertion through the surgical sheath and into opposing jaws (14, 15). The jaws have a plurality of open and closed positions. One of the jaws has a retainer (16) that maintains the lateral displacement (17) between the opposing jaws and prevents the clamp from twisting off a vessel. A resilient assembly (18) including a torsion spring (19) and first and second resilient arms (20, 21) extending to the opposing jaws urges the jaws to a closed position. Each of the resilient arms includes a distal portion which cross each other urging the opposing jaws to a closed position. The clamp further includes a tubular, elongated containment member having a hollow passage (26) that extends therein for receiving the clamp and operating it between its open and closed positions.

[ What is claimed is:] [1.] A surgical device for minimally invasive procedures comprising:a surgical introducer sheath (11) for establishing access to a cavity (12) of a patient (13); anda releasable, surgical clamp (10) particularly adapted for facile introduction into, complete containment in and facile removal from the body of the patient (13) that is insertable through the surgical introducer sheath (11) and into the cavity (12) of the patient (13);wherein the clamp (10) comprises:first and second opposing jaws (14, 15) configured for insertion through the surgical introducer sheath (11) and having an open and a closed position, at least one of said opposing jaws (14 or 15) having a retainer (16) that forms an elongated loop having an atraumatic distal end (32) and that maintains a lateral displacement (17) between said opposing jaws (14, 15), said opposing jaws including said retainer engaging a vessel in at least three separated points when the vessel is positioned therein; anda resilient assembly (18) configured for insertion through the surgical introducer sheath and engagement therewith, extending to said opposing jaws (14, 15), and urging said opposing jaws (14, 15) to at least one of said open and said closed positions when engaging the surgical introducer sheath;whereby the clamp (10) can be contained completely within the cavity (12) of the patient (13) during engagement with the vessel.
