Abstract

The present disclosure relates generally to apparatus, devices, and methods for increasing force distribution at a suture-tissue interface. In some embodiments, a tissue suturing device may include a deployment device and a plurality of tissue supports deployable from the deployment device towards a target tissue. The plurality of tissue supports may each include a central opening for receiving a suture during deployment.

First claim

What is claimed is:

1. A tissue suturing apparatus for an endoscope, comprising:
a tissue suturing device extending from a distal end of the endoscope, the tissue suturing device comprising a plurality of tissue supports, wherein each of the plurality of tissue supports is deployable towards a target tissue, and wherein one or more tissue supports of the plurality of tissue supports is configured to receive a suture during deployment;
a deployment device comprising: a housing containing the plurality of tissue supports; and a cover extending across the housing, the cover including an opening to permit access to the plurality of tissue supports by a needle attached to the suture, wherein the plurality of tissue supports is contained within the deployment device prior to deployment; and
the needle, wherein the needle engages a tissue support of the plurality of tissue supports to deploy the tissue support,
the deployment device comprising an interior channel and a biasing device for biasing the plurality of tissue supports within the interior channel, wherein the plurality of tissue supports are arranged end-to-end within the interior channel.

2. The tissue suturing apparatus of claim 1 , the suture comprising:
a core; and
a sheath, wherein the sheath is operable to expand radially from the core in an area adjacent the target tissue.

3. The tissue suturing apparatus of claim 2 , wherein the sheath comprises a plurality of flexible strands.

4. The tissue suturing apparatus of claim 1 , wherein the plurality of tissue supports comprises one or more of a flexible washer, a sprayable adhesive, a pledget, or a spring-loaded wire.

5. A tissue suturing device, comprising:
a deployment device;
a plurality of tissue supports deployable from the deployment device towards a target tissue, wherein the plurality of tissue supports includes a central opening for receiving a suture during deployment;
a fixed end secured to a distal end of an endoscope;
a free end opposite the fixed end, wherein the deployment device is coupled to one of the fixed end or the free end;
a housing surrounding the plurality of tissue supports, the housing comprising an interior channel and a biasing device for biasing the plurality of tissue supports within the interior channel, wherein the plurality of tissue supports are arranged end-to-end within the interior channel; and
a cover extending across the housing, the cover including an opening for access to the plurality of tissue supports by a needle attached to the suture.

6. The tissue suturing device of claim 5 , the suture comprising:
a core; and
a sheath, wherein the sheath is operable to expand radially from the core in an area adjacent the target tissue.

7. The tissue suturing device of claim 6 , wherein the sheath comprises a plurality of flexible strands.

8. The tissue suturing device of claim 5 , wherein the plurality of tissue supports comprises one or more of a flexible washer, a sprayable adhesive, a pledget, or a spring-loaded wire.
