Suture delivery with asynchronous needle capture

A method for delivering a suture comprising:

• providing an elongated deployment shaft, a needle deployment assembly carried by the shaft, including a plurality of needles carrying suture material, a stabilizer carried by the shaft at a location proximal of the needle deployment assembly, a catcher tube coaxially and slidably disposed over the shaft having a catcher assembly at a distal end, and a sheath coaxially and slidably disposed over the catcher tube;
• advancing the elongated deployment shaft to a desired position in a body;
• reconfiguring the stabilizer from an unexpanded insertion profile to an expanded profile;
• sandwiching tissue to be sutured between a distal end of the sheath and the expanded stabilizer;
• deflecting the plurality of needles radially outwards to a piercing angle from an insertion profile at a distal position with proximal movement relative to the shaft;
• moving the plurality of needles to a proximal position beyond the catcher assembly by passing through the tissue to be sutured;
• engaging the catcher assembly with a first subset of the plurality of needles at a first time when moved distally from the proximal position,
• engaging the catcher assembly with a second subset of the plurality of needles at a second time subsequent to the first time after further distal movement;
• retaining at least a portion of each of the plurality of needles carrying the suture material with the catcher assembly;
• and
• returning a portion of each of the plurality of needles not retained by the needles to the insertion profile at the distal position.
