  • Patent number: 10194901
    Abstract: Systems and methods are provided for suturing tissue. An elongated deployment shaft carries a needle deployment assembly with needles carrying suture material and a stabilizer that is reconfigurable between an unexpanded insertion profile and an expanded profile. A catcher tube over the shaft having a catcher at a distal end may retain at least a portion of the needles carrying the suture material when the needles are passed through the tissue to be sutured into engagement with the catcher. A sheath over the catcher tube may sandwich tissue to be sutured against the stabilizer when expanded under control of first actuator. A second actuator may control the needles.

  • Publication number: 20170273683
    Abstract: Systems and methods are provided for percutaneously suturing tissue. An elongated deployment member having a guide member coaxially disposed over a shaft member may be used to carry a needle deployment member. The needle deployment member may be carried at a distal end of the elongated deployment member and include a plurality of needles releasably secured to the needle deployment member, wherein each needle is routed coaxially within the distal end of the needle deployment member. The needle deployment member may further include a needle pusher driven by a link coaxially disposed within the shaft member, wherein the needle pusher is configured to advance each needle through the distal end of the needle deployment member and coaxially over the proximal end of the needle deployment member to position the plurality of needles at a piercing angle in a proximal direction.
