Rapid Deployment Artificial Chordae Tendinae System

摘要

An embodiment includes an apparatus comprising: a hollow needle with a narrowed inner diameter in a distal third of the needle; and a flexible chord coupled to proximal and distal conduits; wherein the distal conduit is in the needle and distal to the narrowed inner diameter and the proximal conduit is in the needle and proximal to the narrowed inner diameter; wherein: (a)(i) long axes of the proximal and distal conduits are substantially parallel to a long axis of the needle when the proximal and distal conduits are in the needle, and (a)(ii) the proximal and distal conduits are configured to rotate when deployed from the needle such that their long axes are not parallel to a long axis of the chord when the chord is fully extended. Other embodiments are described herein.

1. An artificial chordae tendineae kit comprising:
a hollow first needle including a first proximal end portion having a first proximal aperture, a first distal end portion having a first distal aperture, and a first middle portion coupling the first proximal end portion to the first distal end portion; a flexible first chord coupled to both a first proximal anchor and a first distal anchor; wherein the first proximal end portion includes a first proximal inner diameter directly adjacent the first proximal aperture, the first distal end portion includes a first distal inner diameter directly adjacent the first distal aperture, the first middle portion includes a first narrowed portion with a first middle inner diameter that is less than either of the first proximal inner diameter and the first distal inner diameter; wherein the first chord, the first proximal anchor, and the first distal anchor are all included within the first needle with the first distal anchor distal to the first narrowed portion and the first proximal anchor proximal to the first narrowed portion; wherein the first needle includes a long axis, the first chord includes a long axis, the first proximal anchor includes a long axis, and the first distal anchor includes a long axis; wherein the long axes of the first proximal and distal anchors are substantially parallel to the long axis of the first needle when the first chord is included within the first needle; wherein the first proximal and distal anchors are each configured to rotate when deployed from the first needle such that the long axes of the first proximal and distal anchors are each nonparallel to the long axis of the first chord; wherein the first proximal anchor is deformable and configured to deform to slide past the first narrowed portion.
