Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
111 words
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.
Claim 2
Dependent Claim
111 words
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.
Claim 3
Dependent Claim
12 words
The clamp of claim 1 , wherein the U-shaped wire is continuous.
Claim 4
Dependent Claim
12 words
The clamp of claim 1 , wherein the U-shaped wire is flat.
Claim 5
Dependent Claim
41 words
A combination of the applicator and the clamp according to claim 1 , the applicator comprising the engagement finger in the open space, wherein relative movement of the clamp and the engagement finger transitions the jaws between open and closed positions.
Claim 6
Dependent Claim
19 words
The combination of claim 4 , wherein the applicator further comprises a push rod carrying the engagement finger thereon.
Claim 7
Dependent Claim
38 words
The combination of claim 4 , wherein the push rod is configured to push the clamp out of the applicator while the engagement finger is received in the open space between the pair of arms of the clamp.
Claim 8
Dependent Claim
26 words
The combination of claim 4 , wherein the applicator further comprises a slide pin moveable with respect to the engagement finger and abuttable against the clamp.
Claim 9
Dependent Claim
55 words
The combination of claim 7 , wherein the slide pin is contained within and is extendable from the push rod, and wherein the engagement finger spreads the pair of arms apart when the slide pin is extended from the push rod, and the jaws close to clasp a vessel when the slide pin is withdrawn.
Claim 10
Dependent Claim
151 words
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.
Claim 11
Dependent Claim
151 words
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.
Claim 12
Dependent Claim
11 words
The combination of claim 9 , wherein the wire is continuous.
Claim 13
Dependent Claim
11 words
The combination of claim 9 , wherein the wire is flat.
