SUTURE DELIVERY DEVICE FOR SUTURING TISSUE

摘要

Systems are provided for delivering a suture to close a surgical opening. An elongated deployment member may have at its distal end a retracted counterforce member. The counterforce member may be inserted into the surgical opening and deployed to resist being withdrawn from the opening. A compression member may be slid down the elongated member to compress the tissue to be sutured against the counterforce member. Suture passers loaded with suture ends may be passed through needle tubes within the elongated member to emerge from the elongated member and pierce the tissue to be sutured, then deposit the suture ends with a suture catcher. The suture passers may be withdrawn, leaving the suture ends. The suture catcher may be retracted, retaining the suture ends and the device—elongated member, retracted suture catcher, and retained suture end—may be withdrawn from the surgical opening. The suture may then be completed.

主权项

1. A suture delivery device for suturing tissue comprising:
an elongated deployment member; a counterforce member disposed towards a distal end of the elongated deployment member, wherein the counterforce member is configured to transition between a retracted configuration that facilitates the counterforce member entering an incision and a deployed configuration that resists extracting the counterforce member from an incision; a compression member disposed towards a proximal end of the elongated deployment member with respect to the counterforce member, wherein the compression member is configured to resist entering an incision, and wherein the compression member and the counterforce member transition between a compressed configuration and an uncompressed configuration; a suture catcher disposed towards the distal end of the elongated deployment member, wherein the suture catcher is configured to transition between a retracted configuration that facilitates the suture catcher entering an incision and a deployed configuration that facilitates catching a suture; a first needle track associated with the elongated deployment member and oriented towards a first area of the suture catcher when in the deployed configuration; and a second needle track associated with the elongated deployment member and oriented towards a second area of the suture catcher when in the deployed configuration, wherein the first area of the suture catcher when in the deployed configuration and the second area of the suture catcher when in the deployed configuration are situated on the suture catcher to allow their placement on opposite sides of an incision.
