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.
Claims10
A tissue suturing apparatus configured to be coupled to an endoscope, the tissue suturing apparatus comprising:
- a tissue suturing device configured to be coupled to a distal end of an endoscope, the tissue suturing device comprising a needle movable with respect to the endoscope to be passed back and forth through tissue;
- and
- a housing containing a plurality of tissue supports mounted with respect to the tissue suturing device to be individually and sequentially deployed over the needle by passing the needle through a tissue support to puncture and extend through the tissue support, the tissue supports configured to be released from the needle to be deployed on the tissue, wherein the housing defines an interior channel and includes a biasing device biasing the plurality of tissue supports through the interior channel.
A method, comprising:
- providing a tissue suturing apparatus comprising:
- a tissue suturing device configured to be coupled to a distal end of an endoscope, the tissue suturing device comprising a needle movable with respect to the endoscope to be passed back and forth through tissue;
- and
- a housing containing a plurality of tissue supports mounted with respect to the tissue suturing device to be individually and sequentially deployed over the needle by passing the needle through a tissue support to puncture and extend through the tissue support, the tissue supports configured to be released from the needle to be deployed on the tissue, wherein the housing defines an interior channel and includes a biasing device biasing the plurality of tissue supports through the interior channel;
- passing the needle and a suture of the tissue suturing device through a target tissue, the tissue suturing device extending from a distal end of an endoscope;
- deploying a first tissue support from the tissue suturing device to a position along a first portion of the target tissue;
- and
- deploying a second tissue support from the tissue suturing device to a position along a second portion of the target tissue, wherein tightening the suture brings the first tissue support and second tissue support closer together.
