Patent ID: 11076849

Abstract:
An elongated deployment shaft carrying a needle deployment assembly with needles carrying sutures and a stabilizer. A catcher tube over the shaft having a catcher assembly at a distal end may retain a portion of the needles when passed through the tissue into engagement with catcher assembly. The catcher and needle deployment assemblies are configured to asynchronously engage the plurality of needles when moved distally beyond the catcher assembly. A sheath over the catcher tube may sandwich the tissue against the stabilizer when expanded. A first actuator may move catcher tube distally to decrease distance between proximal and distal ends of the stabilizer expand it and may move the sheath distally to sandwich the tissue. A second actuator may deflect the needles outward to move proximally through the tissue and engage the catcher and return a portion of each not retained by the catcher to a distal position.
