Abstract
A solution is provided to release a tissue cinching loop within a body having a first thread having a first end and a second end, and a second thread having a first half having a first tip, a second half having a second tip, a bottom half having a link, and a top half, wherein the first end is inserted through the link. A first knot is formed around the first thread with the top half thereby forming a loop where the diameter of the loop decreases as the knot is pushed into the body and the first thread is pulled out of the body and where the loop is released within the body when the first end is pulled out of the body.
Claims21
A method for releasing a tissue cinching loop within a cavity, comprising:
- providing a first thread having a first end, a second end, a first segment adjacent the first end, a second segment adjacent the second end, and a link joining the first segment and the second segment;
- providing a second thread having a first closed loop and a second closed loop
- inserting the first thread through the first closed loop in the second thread such that the first thread passes once and only once through the closed loop, thereby positioning the two segments of said first thread in a generally parallel arrangement, each segment being on an opposite side of said first closed loop in said second thread;
- pulling said first thread first end and second end through a first opening and a second opening within the cavity;
- joining said first thread to the second thread such that the first and second segments of the first thread pass through the second loop of the second thread to form a cinching loop;
- pulling said first thread first and second ends away from said cavity;
- thereby forming a tissue cinching loop in the second thread;
- and
- removing said first thread from said cavity thereby releasing said tissue cinching loop within said cavity.
An apparatus to release a tissue cinching loop within a cavity, comprising:
- a first thread having a first end and a second end, a first segment adjacent the first end, a second segment adjacent the second end, and a link joining the first segment and the second segment, wherein the first and second segments are generally parallel;
- a second thread having a first closed loop comprising a first portion and a second portion, said portions being joined by a first link and a second link such that the first portion and the second portion are generally parallel;
- and
- a knot in the second thread, said knot forming a second closed loop of fixed dimension located adjacent to the second link of the second thread, said second closed loop being slidably disposed about the first portion and the second portion of the second thread;
- wherein the first thread passes once and only once between the first and second portions of the second thread and is disposed with the link of the first thread adjacent to the first link of the second thread such that the first thread first and second segments proximate the link of the first thread extend in a direction opposite the direction in which the first and second portions of the second thread leave the first link of the second thread.
An apparatus to release a tissue cinching loop within a cavity, comprising:
- a first thread having a first end and a second end, a first segment adjacent the first end, a second segment adjacent the second end, and a link joining the first segment and the second segment, wherein the first and second segments are generally parallel;
- a second thread having a first end and a second end;
- a first knot in the second thread, said knot forming a first closed loop of fixed dimension located adjacent to the first end of the second thread;
- and
- a second knot in the second thread, said knot forming at least one second closed loop located adjacent to the second end of the second thread, said at least one second closed loop being slidably disposed about the second thread between the first and second knots;
- wherein the first thread passes once and only once through the first closed loop of the first knot of the second thread such that the first thread first segment and second segment proximate the link of the first thread extend in a direction opposite the direction in which the second thread leaves the first knot of the second thread.
