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.
