Abstract:

Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.

Abstract:

Fixation system for fixation of leaflets of a heart valve including an implantable fixation device having a first arm and a second arm, a first proximal element moveable relative to the first arm between a first position and a second position, and a second proximal element moveable relative to the second arm between a first position and a second position. The fixation system includes a delivery device having a catheter, a first proximal element line and a second proximal element line, and a handle having a first and second proximal element line handles coupled to the first proximal element line and the second proximal element line, respectively. The handle can include an interlock moveable between an unlocked position and a locked position.
