Claim Text:
1. A vessel closure device, the device comprising: a guide member having a proximal end, a distal end, and one or more lumens extending from the proximal end to one or more openings adjacent the distal end, a distalmost end of the device being formed with a tapered portion disposed distal the one or more openings, a distal end of the tapered portion being the distalmost end of the device, the proximal end of the guide member being mounted to a proximal handle; a pair of needle guides disposed at least partially within the guide member, the pair of needle guides being configured to move between a first position wherein the pair of needle guides are substantially straightened at least partially within the guide member and a second position wherein the pair of needle guides at least partially extend through the one or more openings radially and distally away from both the guide member and the tapered portion, each of the pair of needle guides having a shaft of a needle disposed therein, a deployment angle of each of the needles relative to a longitudinal axis of the guide member is greater than a taper angle of the tapered portion relative to the longitudinal axis of the guide member, wherein upon the pair of needle guides extending radially and distally away relative to both the guide member and the tapered portion, each of the pair of needle guides is noncontiguous with the tapered portion; and an angle adjustment member movably attached to the guide member, the angle adjustment member having a proximal end and a distal end, the angle adjustment member being configured to move between a retracted position wherein the distal end of the angle adjustment member is positioned proximal to the one or more openings and an extended position where the distal end of the angle adjustment member is selectively positioned distal to the one or more openings with the pair of needle guides extending distally from the distal end of the angle adjustment member so as to deflect the pair of needle guides radially toward the guide member when the pair of needle guides are in the second position.
