Apparatus and methods for sealing a vascular puncture
First Claim
1. A system for sealing a puncture extending through tissue, comprising:
- an introducer sheath comprising a proximal end, a distal end sized for insertion through a puncture, and a lumen extending between the proximal and distal ends;
an elongate positioning member sized for insertion into the introducer sheath lumen and having an expandable element on a distal end thereof and a tension indicator on a proximal end thereof; and
wherein the tension indicator comprises a distal housing portion substantially fixed on the positioning member proximal end, and a proximal housing portion movable proximally relative to the distal housing portion, the proximal housing portion biased distally towards the distal housing portion.

Abstract
An apparatus for sealing a puncture includes a positioning member including a proximal end, a distal end sized for insertion into a puncture, an expandable element on the distal end, and a tension indicator on the proximal end. The tension indicator includes a distal housing portion fixed relative to the proximal end, and a proximal housing portion or handle movable proximally relative to the distal housing portion. The handle is biased towards the distal housing portion such that, when sufficient tensile force is applied between the expandable element and the handle, the handle moves away from the distal housing portion. During use, the distal end is introduced through a puncture into a vessel, the expandable element is expanded, and the positioning member is partially withdrawn until the expanded element contacts a wall of the vessel and the handle separates from the distal housing portion, indicating that sufficient tension is applied.

10. A tension indicator apparatus for providing temporary hemostasis within a puncture extending through tissue to a body lumen, comprising:
-
an elongate member comprising a proximal end and a distal end sized for introduction into a puncture; an expandable element on the distal end sized for introduction into a puncture in a collapsed condition, the expandable element being larger than the puncture in an expanded condition; and a tension indicator on the proximal end for indicating when a desired tensile force between the distal end and the tension indicator is applied; and
wherein the tension indicator comprises a distal housing portion substantially fixed on the proximal end and a proximal housing portion movable proximally relative to the distal housing portion, the proximal housing portion biased distally towards the distal housing portion. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system for sealing a puncture extending through tissue, comprising:
-
an elongate positioning member comprising a proximal end, a distal end sized for insertion into a puncture extending through tissue, an expandable element on a distal end thereof, and a housing on the proximal end, the housing comprising a first housing portion substantially fixed on the proximal end, and a second housing portion movable relative to the first housing portion to allow the second housing portion to separate from the first housing portion biased distally towards the first housing portion, thereby providing a visual indicator that a desired force is being applied between the positioning member distal end and the second housing portion; a tubular member carried on the positioning member, the tubular member comprising a proximal end, a distal end sized for insertion into a puncture, and a lumen extending between the tubular member proximal and distal ends; a sealant disposed within the tubular member lumen; and a pusher member disposed within the tubular member lumen for deploying the sealant distally from the tubular member lumen when the tubular member is retracted proximally relative to the pusher member. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
