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.

摘要： A knot may be formed in suture material using a device having an elongated body with a longitudinal axis and a holder. A rail portion of the suture material is secured with a first grasper on the elongated body and a non-rail portion of the suture material is secured with a second grasper on the holder. A plurality of helical windings may be created with the non-rail portion. Detaching the holder from the elongated body in a motion away from the longitudinal axis of the elongated body completes the knot. The holder may be wrapped around the elongated body in a knot-forming pattern.

摘要： Systems and methods are provided for suturing tissue. An elongated deployment shaft carries a needle deployment assembly with needles carrying suture material. A needle catcher is disposed over the shaft and configured to engage and retain at least a portion of each of the needles carrying the suture material when the needles are passed through the tissue to be sutured to a proximal position.
