Apparatus and methods for delivering a vascular closure device to a body lumen
First Claim
1. An apparatus for delivering a closure element into a passage communicating with an opening into a body lumen, comprising:
- an elongate member comprising proximal and distal ends;
an annular clip carried by the elongate member for closing the opening;
a locator member coupled to the elongate member, the locator member having a distal portion extending distally beyond the distal end of the elongate member;
one or more positioning elements on the distal portion of the locator member, the positioning elements being selectively expandable between a substantially axial collapsed configuration and a substantially transverse expanded configuration; and
a housing slidably disposed on the exterior of the elongate member, the housing configured for housing the clip and releasably holding the clip therein, the housing being actuable for advancing the clip distally towards the distal end of the elongate member.

Abstract
An apparatus for delivering a closure element into a puncture communicating with a blood vessel includes an introducer sheath, and a locator member disposed within the sheath, the locator member having a distal portion extending distally beyond the distal end of the sheath. A plurality of splines are provided on the distal portion of the locator member, the splines being selectively expandable between an axial collapsed configuration and a transverse expanded configuration. An actuator is coupled to the locator member for controllably expanding the splines. A housing is slidably disposed on the sheath for deploying a closure element, such as a vascular clip. The locator actuator may automatically collapse the splines upon advancement of the housing.

17. An apparatus for delivering an annular clip into a passage communicating with an opening into a body lumen, comprising:
-
an elongate member comprising proximal and distal ends;
a housing slidable along an exterior of the elongate member, the housing configured for releasably holding annular clip therein;
a locator member comprising a distal portion extending distally beyond the distal end of the elongate member; and
one or more positioning elements on the distal portion of the locator member, the positioning elements being selectively expandable between a substantially axial collapsed configuration and a substantially transverse expanded configuration. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. An apparatus for delivering a closure element into a passage communicating with an opening into a body lumen, comprising:
-
a tubular member comprising proximal and distal ends;
an annular housing overlying the tubular member and slidable towards the distal end of the tubular member;
an annular clip releasably carried within the housing; and
a locator member within the tubular member, the locator member having a distal portion extending distally beyond the distal end of the tubular member, the distal portion comprising a plurality of positioning elements, the positioning elements being selectively expandable between a substantially axial collapsed configuration and a substantially transverse expanded configuration. - View Dependent Claims (27, 28, 29, 30)

31. A method for delivering a closure element into a passage communicating with an opening in a wall of a body lumen, the method comprising:
-
positioning an elongate member through a patient'"'"'s skin towards the body lumen via the passage, the elongate member including a lumen extending between its proximal and distal ends; and
providing a locator comprising a distal portion extending beyond the distal end of the elongate member and into the body lumen;
expanding one or more positioning elements on the distal portion of the locator from a collapsed configuration to an expanded configuration;
withdrawing the elongate member and locator partially until the positioning elements in their expanded configuration contact the wall of the body lumen, thereby providing a tactile indication of a location of the distal end of the elongate member; and
delivering a clip located in a housing slidably mounted on the elongate member via the elongate member into the passage by advancing the housing distally along the exterior of the elongate member, the housing releasably holding the clip therein. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
