Releasable, surgical clamp
First Claim
1. A releasable surgical clamp, comprising:
- a U-shaped wire, wherein the base of the U-shape is located in a proximal portion;
a pair of arms located distal to the base and located partially in the proximal portion and partially in a middle portion and forming an open space in the middle portion, the interior distance between the arms in the middle portion being greater than the interior distance between the arms in the proximal portion, wherein the proximal portion is configured for sliding engagement with an engagement finger of an applicator; and
a jaw located distal to each arm, the jaws being biased closed and substantially coplanar when in a closed position.

Abstract
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.

9. A combination applicator and surgical clamp, the combination comprising:
-
a releasable, surgical clamp comprising, a U-shaped wire, wherein the base of the U-shape is located in a proximal portion;
a pair of arms located distal to the base and located partially in the proximal portion and partially in a middle portion and forming an open space in the middle portion, the interior distance between the arms in the middle portion being greater than the interior distance between the arms in the proximal portion; and
a jaw located distal to each arm, the jaws being biased closed and substantially coplanar when in a closed position; and
an applicator comprising an engagement finger, a push rod carrying the engagement finger thereon, and a slide pin contained within and extendable from the push rod, wherein when the slide pin is extended from the push rod, the engagement finger spreads the pair of arms apart. - View Dependent Claims (10, 11)
