Abdominal aortic clamp

Claim 2

A vascular clamp suitable for temporary occlusion of the abdominal aorta, comprising, in combination: first and second elongate rigid members slidable lengthwise relative to each other; first and second jaws parallel to each other and laterally extending respectively from adjacent one ends of said members and movable in a plane between open and closed positions; and first and second handles pivotally connected and extending laterally from respective adjacent other ends of said members in a direction opposite of said jaws for manipulating said jaws in said plane.

Claim 3

A vascular clamp according to claim 1 wherein: said jaws form spoon-like arcs for minimizing distortion of the posterior wall of the aorta when clamped therebetween.

Claim 4

A vascular clamp according to claim 2 wherein: a chord drawn between the ends of each of said jaws forms with said members an angle of approximately 100 degrees in the pivotal plane of said handles.

Claim 5

A vascular clamp according to claim 1 wherein: said first and second jaws each include a plurality of rows of serrated teeth aligned along the length of said jaws.

Claim 6

A vascular clamp, comprising, in combination: first and second elongate handles pivotally connected to each other and defining proximal ends having finger grips for manipulation in a single plane in scissors-like motion; first and second elongate rigid members, one end of each extending laterally from the distal end of respective ones of said handles and slidable lengthwise relative to each other; and first and second jaws parallel to each other and extending laterally from respective other ends of said members in a direction opposite of said handles and movable in opposition to each other in said plane.

Claim 7

A vascular clamp, comprising, in combination: first and second elongate handles pivotally connected to each other and defining proximal ends having finger grips for manipulation in a single plane in scissors-like motion; first and second elongate rigid members, one end of each extending laterally from the distal end of respective ones of said handles and slidable lengthwise relative to each other; and first and second jaws parallel to each other and extending laterally from respective other ends of said members in a direction opposite of said handles and movable in opposition to each other in said plane.

Claim 8

A vascular clamp according to claim 5 wherein: said jaws arch upward.

Claim 9

A vascular clamp according to claim 6 wherein: a chord drawn between the ends of each of said jaws forms with said members an angle of approximately 100 degrees in the pivotal plane of said handles.

Claim 10

A vascular clamp according to claim 5 wherein: said first and second jaws each include a plurality of rows of serrated teeth aligned along the length of said jaws.

Claim 11

A vascular clamp suitable for temporary occlusion of the abdominal aorta, comprising, in combination: first and second elongate rigid members, said first member slidable in a track formed along the length of said second member; first and second jaws parallel to each other and laterally extending respectively from adjacent one ends of said members and formed to grip opposite walls of the aorta; pivotally connected first and second handles defining proximal ends with finger grips, and distal ends operatively connected respectively to adjacent other ends of said first and second members for manipulating said jaws between open and closed positions; and said other end of said first member includes an aperture slidably receiving the distal end of said second handle, and said other end of said second member is rigidly connected to the distal end of said second handle.

Claim 12

A vascular clamp suitable for temporary occlusion of the abdominal aorta, comprising, in combination: first and second elongate rigid members, said first member slidable in a track formed along the length of said second member; first and second jaws parallel to each other and laterally extending respectively from adjacent one ends of said members and formed to grip opposite walls of the aorta; pivotally connected first and second handles defining proximal ends with finger grips, and distal ends operatively connected respectively to adjacent other ends of said first and second members for manipulating said jaws between open and closed positions; and said other end of said first member includes an aperture slidably receiving the distal end of said second handle, and said other end of said second member is rigidly connected to the distal end of said second handle.

Claim 13

A vascular clamp according to claim 9 wherein: said second member forms with said second handle an angle of approximately 120 degrees in the pivotal plane of said handles.

Claim 14

A vascular clamp according to claim 9 further comprising: locking means extending from said handles for maintaining said jaws compressed about the aorta.

Claim 15

A vascular clamp, comprising, in combination: first and second elongate handles pivotally connected to each other, defining proximal ends having finger grips for manipulation in scissors-like motion; first and second elongate rigid members, each operatively connected at one end to the distal end of one of said handles, said first member slidable in a track formed along the length of said second member, said one end of said first member includes an aperture slidably receiving the distal end of said first handle, and said one end of said second member is rigidly connected to the distal end of said second handle; and first and second jaws parallel to each other, each extending laterally from another end of a respective one of said members opposite its said one end.

Claim 16

A vascular clamp, comprising, in combination: first and second elongate handles pivotally connected to each other, defining proximal ends having finger grips for manipulation in scissors-like motion; first and second elongate rigid members, each operatively connected at one end to the distal end of one of said handles, said first member slidable in a track formed along the length of said second member, said one end of said first member includes an aperture slidably receiving the distal end of said first handle, and said one end of said second member is rigidly connected to the distal end of said second handle; and first and second jaws parallel to each other, each extending laterally from another end of a respective one of said members opposite its said one end.

Claim 17

A vascular clamp according to claim 12 wherein: said second member forms with said second handle an angle of approximately 120 degrees in the pivotal plane of said handles.

Claim 18

A vascular clamp according to claim 12 further comprising: locking means extending from said handles for maintaining said jaws compressed about the aorta.
