Abstract
Abstract An apparatus and method are disclosed for applying a surgical clip to an exterior wall of a blood vessel to at least partially close a hole formed therein. The apparatus includes a handle portion, an elongated body extending distally from the handle portion and dimensioned to extend through a hole in the wall of a blood vessel, and a collapsible locator associated with a distal end portion of the elongated body and mounted for movement between a collapsed position and an expanded deployed position. The locator is adapted to expand within an interior lumen of the blood vessel to maintain the distal end portion of the elongated body in a desired location with respect to the hole in blood vessel wall such that a surgical clip releasably supported adjacent the distal end portion of the elongated body can be applied to the exterior wall of the blood vessel to close the hole formed therein.

Claim 10
Dependent Claim
70 words
An apparatus a recited in Claim 9, wherein a pair of diametrically opposed camming ramps are formed adjacent a distal end of the elongated body distal of the clip support structure, the camming ramps causing the opposed arms of the surgical clip to move between a closed position and an open position in response to longitudinal movement of the outer tubular member from the distal position toward the proximal position.
Claim 11
Independent Claim
31 words
An apparatus as recited in any one of the preceding claims, wherein an actuation handle is operatively associated with the handle portion and is mounted for manipulation through an actuating stroke.
Claim 12
Dependent Claim
64 words
An apparatus as recited in Claim 11, wherein movement of the actuation handle through a first segment of the actuating stroke causes the outer tubular member to move from the proximal position to the distal position, and movement of the actuation handle through a second segment of the actuating stroke causes the control rod to move from the distal position to the proximal position.
Claim 13
Dependent Claim
29 words
An apparatus as recited in Claim 12, wherein movement of the actuation handle through the second segment of the actuating stroke releases the control knob from an engaged position.
Claim 14
Dependent Claim
76 words
An apparatus as recited in Claim 12 or 13, wherein distal and proximal actuating members are supported with the handle portion and are operatively connected to the actuation handle, the distal actuating member connected to a proximal end of the outer tubular member and the proximal actuating member connected to a release tube which is dimensioned to interact with the control knob upon movement of the actuation handle through the second segment of the actuating stroke.
Claim 15
Dependent Claim
