Monorail system for vascular closure device and methods

摘要

A tissue puncture closure assembly including a wire assembly and first and second devices. The wire assembly includes a first wire member and a second wire member that each include a distal end portion and a proximal end portion. At least portions of the second wire member are arranged side-by-side with the first wire member. The distal end portion of the first wire member is connected to the distal end portion of the second wire member, and a proximal end portion of the first wire member is disconnected from the proximal end portion of the second wire member. The first device is operable to advance over the first wire member. The second device is operable to advance over the second wire member.

主权项

1. A tissue puncture closure assembly, comprising:
a wire assembly including: a first wire member having a distal end portion comprising a first length and a proximal end portion, the first wire member having a circular cross-sectional shape; a second wire member having a distal end portion comprising a second length and a proximal end portion, the second wire member having a crescent cross-sectional shape that follows an outer contour of the circular cross-sectional shape of the first wire member; wherein the first length and the second length are arranged side-by-side with each other and are fixedly connected to each other at a plurality of connection points along the first and second lengths, and the proximal end portion of the first wire member is arranged side-by-side with the proximal end portion of the second wire member wherein the proximal end portions are disconnected from each other; a first device having a distal end portion, the first device being configured to advance over the first wire member, the distal end portion of the first wire member configured to advance through a lumen in the first device past the distal end portion of the first device; a sealing pad deployable from a pad lumen in the first device, the sealing pad having a cross-sectional shape mirroring a cross-section of the pad lumen in the first device upon deployment from the pad lumen; a second device configured to advance over the second wire member.
