Non-invasive surgical ligation clip system and method of using
First Claim
Patent Images
1. A method of using a clip system, comprising:
- (a) providing a clip having a pair of jaws coupled together and biased toward each other, at least one of the jaws being coupled to a flexing section;
(b) placing the clip in a lumen at a proximal opening of a needle, the needle engaging the flexing section to exert stress on the flexing section, thereby separating at least a portion of the first and second jaws;
(c) positioning a distal opening of the needle at an anatomical location within a patient'"'"'s body;
(d) reducing stress on the flexing section to allow the first and second jaws to move closer together around a tissue structure; and
(e) releasing the clip from the distal opening of the needle with the clip remaining in engagement with the tissue structure.

17. A clip system for application to mammalian tissue, comprising:
-
a needle including a needle bore that extends from a proximal opening to a distal opening, the distal opening being insertable into a patient'"'"'s body; and a clip device that inserts into the proximal opening, including; a first jaw having a first clamping section and a second jaw having a second clamping section opposing the first clamping section, at least a portion of the first and second jaws being able to separate from each other, and a first flexing section coupled to at least the first jaw, the first flexing section being adjustable between a first shape in which the first and second clamping sections at least partially engage one another and a stressed shape by compression of the first flexing section against the needle bore that causes the first and second clamping sections to be at least partially separated from one another; wherein, when the first flexing section is in the stressed shape, the clip device has a lateral dimension smaller than the inner dimension of the needle bore so that the entire clip device is deliverable from the proximal opening of the needle bore to the distal opening of the needle bore. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)

48. A clip system for application to mammalian tissue, comprising:
-
a needle including a needle bore that extends from a proximal opening to a distal opening, the distal opening being deliverable to a targeted internal tissue; and a clip device that inserts into the proximal opening of the needle bore and superelastically deforms therein without forming a permanent kink, the clip device including; a first jaw having a first clamping section and a second jaw having a second clamping section opposing the first clamping section and being biased toward the first clamping section, the distal portions of the first and second jaws being able to separate from each other, and a first flexing section coupled to at least the first jaw, the first flexing section being adjustable between a first shape in which the first and second clamping sections extend generally parallel to one another and a stressed shape that causes at least distal ends of the first and second clamping sections to separate from one another, wherein the first flexing section adjusts to the stressed shape by compression of the first flexing section against the needle bore; wherein, when the first flexing section is in the first shape, the clip device has a lateral dimension greater than the inner dimension of the needle bore, and wherein, when the first flexing section is in the stressed shape, the clip device superelastically deforms to a lateral dimension that is smaller than the inner dimension of the needle bore so that the entire clip device is deliverable from the proximal opening of the needle bore to the distal opening of the needle bore. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)
