摘要:
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. A first actuator may move the catcher tube distally relative to the shaft to decrease a distance between the proximal end of the stabilizer and the distal end of the stabilizer to expand the stabilizer and may move the sheath distally relative to the shaft to sandwich the tissue. A second actuator may deflect the needles radially outward to move proximally to pass through the tissue to be sutured and engage the catcher and then return a portion of each not retained by the catcher to a distal position for withdrawal of the device.
