Vascular closure device with improved side loading

摘要

A tissue puncture closure device includes a vessel locator and a sealing plug delivery member. The vessel locator includes an expandable member. The sealing plug delivery member includes a carrier tube, a sealing plug, and a locking member. The carrier tube includes a distal end and a side opening, the side opening extending proximally from the distal end along at least a portion of a length of the carrier tube to provide lateral insertion of the vessel locator into an interior of the carrier tube. The sealing plug includes a lumen and a slot extending from a distal end to a proximal end of the sealing plug, wherein the slot provides lateral access of the vessel locator into the lumen. The locking member is operable to retain the vessel locator within the sealing plug delivery member.

1. A tissue puncture closure device, comprising:
a vessel locator comprising an expandable member; a sealing plug delivery member, comprising:
a carrier tube having a distal end and a side opening, the side opening extending proximally from the distal end along at least a portion of a length of the carrier tube to provide lateral insertion of the vessel locator into an interior of the carrier tube;a sealing plug having a lumen and a slot extending from a distal end to a proximal end of the sealing plug, the slot providing lateral access of the vessel locator into the lumen;a locking member operable to retain the vessel locator within the sealing plug delivery member; wherein the locking member rotates external to the carrier tube between a first rotated position covering at least a portion of one of the side opening of the carrier tube and the slot of the sealing plug and a second rotated position removed from covering the side opening and slot, the locking member being longitudinally repositionable relative to the carrier tube while in the first rotated position, the locking member configured to rotate around a longitudinal axis of the sealing plug, the locking member being positionable along a length of the carrier tube while in the first rotated position.
