Abstract: An implant system and method of delivery includes a catheter system including a sling catheter having a plurality of distal openings and a delivery catheter, disposed within the sling catheter and having a distal port. Suture coupled anchors may be sequentially delivered by the delivery catheter to a cardiac treatment site by aligning the port of the delivery catheter with different openings of the sling catheter and pushing the anchor through the port and the sling catheter to embed the anchor into cardiac tissue such as tissue of a papillary muscle. Each anchor may have a linear configuration for translation within the delivery catheter and a biased configuration that inhibits its reentry into the sling catheter once deployed. Once all anchors are deployed, the suture may be tightened, the anchored portion of the sling catheter may be detached, and the catheter system withdrawn.

Abstract: A system for transluminal delivery of cardiac repair components into a heart includes a visualization catheter having an imaging device disposed at a distal end. An anchor lumen extends through the visualization catheter to an anchor port disposed on its distal wall. An adjustment mechanism is translatably disposed within the visualization catheter and configured to adjust a height of the anchor port relative to a septum of the heart. The imaging device may be used to visualize the placement of anchors expelled from the port into a tissue target. The adjustment mechanism enables accurate placement of multiple anchors along a consistent axis within the heart by rotating the visualization catheter to align the port with different tissue targets. The anchors may be coupled to sutures and the tissue targets may include papillary muscles that are reconfigured by pulling together and securing the sutures to approximate a healthy papillary structure.
