Abstract
Abstract A clamp for clamping a body structure in a patient. The clamp includes a flexible cable housed within a sheath. The cable and sheath extend between a clamp and a handle. The cable actuator. The cable extends through a sheath which is anchored at the clamp and the actuator for actuating jaws from a proximal end of the clamp. A malleable positioner is provided for positioning the clamp about the body structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
277 words
A method of clamping a structure in a patient, comprising the steps of: providing a clamp, a cable puller, a flexible sheath, a handle, and a flexible cable, the handle having a first sheath holder and the clamp having a second sheath holder, the sheath extending between the first and second sheath holders, the cable being at least partially housed within the sheath and generally conforming to a shape of the sheath, the cable also being coupled to the cable puller and the cable puller being adapted to displace the cable relative to the sheath, the clamp having a first jaw and a second jaw, the first and second jaws being movable relative to one another between an open position and a closed position, the first and second jaws being coupled to the cable so that the first and second jaws move between the open and closed positions when the cable is moved by the cable puller, the flexible sheath and flexible cable being deformable so that the cable puller can move the cable relative to the sheath when the flexible sheath is curved, the sheath and the cable each having a length of at least six inches; introducing the clamp into a patient; moving the cable puller thereby displacing the cable relative to the sheath and moving the first and second jaws to the open position; positioning the body structure of a patient between the first and second jaws after the moving step; clamping the body structure by moving the cable puller thereby closing the jaws around the body structure; and moving the first and second jaws to the open position and unclamping the body structure.
Claim 2
Independent Claim
277 words
A method of clamping a structure in a patient, comprising the steps of: providing a clamp, a cable puller, a flexible sheath, a handle, and a flexible cable, the handle having a first sheath holder and the clamp having a second sheath holder, the sheath extending between the first and second sheath holders, the cable being at least partially housed within the sheath and generally conforming to a shape of the sheath, the cable also being coupled to the cable puller and the cable puller being adapted to displace the cable relative to the sheath, the clamp having a first jaw and a second jaw, the first and second jaws being movable relative to one another between an open position and a closed position, the first and second jaws being coupled to the cable so that the first and second jaws move between the open and closed positions when the cable is moved by the cable puller, the flexible sheath and flexible cable being deformable so that the cable puller can move the cable relative to the sheath when the flexible sheath is curved, the sheath and the cable each having a length of at least six inches; introducing the clamp into a patient; moving the cable puller thereby displacing the cable relative to the sheath and moving the first and second jaws to the open position; positioning the body structure of a patient between the first and second jaws after the moving step; clamping the body structure by moving the cable puller thereby closing the jaws around the body structure; and moving the first and second jaws to the open position and unclamping the body structure.
Claim 3
Dependent Claim
44 words
The method of claim 1, wherein: the providing step is carried out with an introducer releasably coupled to the clamp; and the positioning step is carried out by manipulating the introducer so that the first and second jaws are positioned around the body structure.
Claim 4
Dependent Claim
20 words
The method of claim 2, further comprising the step of: disengaging the introducer from the clamp after the positioning step.
Claim 5
Dependent Claim
35 words
The method of claim 1, wherein: the providing step is carried out so that the first and second jaws move substantially parallel to one another when moving from the open position to the closed position.
Claim 6
Dependent Claim
20 words
The method of claim 1, wherein: the providing step is carried out with the contact surfaces comprising an elastomeric material.
Claim 7
Dependent Claim
19 words
The method of claim 1, wherein: the positioning step is carried out with the structure being a blood vessel.
Claim 8
Dependent Claim
25 words
The method of claim 1, wherein: the providing step is carried out with a spring biasing the first and second jaws toward the closed position.
Claim 9
Dependent Claim
32 words
The method of claim 7, wherein: the providing step is carried out with the spring having means for adjusting a force which biases the first and second jaws toward the closed position.
Claim 10
Independent Claim
254 words
A method of clamping a structure in a patient, comprising the steps of: providing a clamp, a cable puller, a flexible sheath, a handle, and a flexible cable, the handle having a first sheath holder and the clamp having a second sheath holder, the sheath extending between the first and second sheath holders, the cable being at least partially housed within the sheath and being coupled to the cable puller, the cable puller being adapted to displace the cable relative to the sheath, the clamp having a first jaw and a second jaw, the first and second jaws being movable relative to one another between an open position and a closed position, the first and second jaws being coupled to the cable so that the first and second jaws move between the open and closed positions when the cable is moved by the cable puller, the first and second jaws having atraumatic contact surfaces, the sheath and cable each having a length of at least six inches; introducing the clamp into a patient; moving the cable puller thereby displacing the cable relative to the sheath and moving the first jaw to the open position; and positioning a body structure of a patient between the first and second jaws after the moving step; and closing the jaws around the body structure by moving the cable puller; the moving step being carried out with the first and second jaws having jaw surfaces remaining substantially parallel to one another when moving between the open and closed positions.
Claim 11
Independent Claim
254 words
A method of clamping a structure in a patient, comprising the steps of: providing a clamp, a cable puller, a flexible sheath, a handle, and a flexible cable, the handle having a first sheath holder and the clamp having a second sheath holder, the sheath extending between the first and second sheath holders, the cable being at least partially housed within the sheath and being coupled to the cable puller, the cable puller being adapted to displace the cable relative to the sheath, the clamp having a first jaw and a second jaw, the first and second jaws being movable relative to one another between an open position and a closed position, the first and second jaws being coupled to the cable so that the first and second jaws move between the open and closed positions when the cable is moved by the cable puller, the first and second jaws having atraumatic contact surfaces, the sheath and cable each having a length of at least six inches; introducing the clamp into a patient; moving the cable puller thereby displacing the cable relative to the sheath and moving the first jaw to the open position; and positioning a body structure of a patient between the first and second jaws after the moving step; and closing the jaws around the body structure by moving the cable puller; the moving step being carried out with the first and second jaws having jaw surfaces remaining substantially parallel to one another when moving between the open and closed positions.
