Abstract
Suture clips configured to be placed in a predetermined path of a suturing needle that advances through a device inserted to a body cavity, and remotely operated from that position to secure and clamp suturing. In some embodiments, a suture tightening device is placed in the predetermined path and configured to capture the suture and shorten a length of tissue-engaged suture by pulling on the suture. In some embodiments, sensors are placed along the needle path and used to provide an indication of needle position and/or status.
Claims19
A bougie configured for placing suturing in a body cavity wall, the bougie comprising:
- a vacuum clamping domain, sized for insertion into the body cavity, and comprising surfaces defining an interior space, and apertures into the interior space configured to receive tissue of the body cavity wall upon application of suction thereto;
- a needle within the interior space, with suture attached to the needle;
- and
- a suture clip within the interior space;
- wherein the needle is actuatable to translate along a path within the interior space while carrying the suture through the tissue;
- and
- wherein the suture clip is positioned to capture the suture at a position along the path, and operable to clamp the captured suture
- wherein said bougie comprising a suture tightener at least partially within the interior space, said suture tightener also positioned to capture the suture at a position along the path, and operable, from outside the bougie, to move to apply a pulling force on the suture to reduce a length of tissue-engaged suture;
- and
- the suture tightener comprises an aperture positioned along the path, and the suture tightener captures the suture when the needle pulls the suture through the aperture of the suture tightener.

- and
- wherein the suture clip is positioned to capture the suture at a position along the path, and operable to clamp the captured suture
- wherein said bougie comprising a suture tightener at least partially within the interior space, said suture tightener also positioned to capture the suture at a position along the path, and operable, from outside the bougie, to move to apply a pulling force on the suture to reduce a length of tissue-engaged suture;
- wherein the suture captured by the suture tightener slides freely with respect to the suture tightener while the suture tightener moves to reduce the length of tissue-engaged suture;
- and
- wherein the suture tightener, when moved to reduce the length of tissue-engaged suture, doubles over the suture so that both ends of the suture are on a same side of the suture tightener.
