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the suture may be tightened, the anchored portion of the sling catheter may be detached, and the catheter system withdrawn.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: An alignment tool for loading a stent includes a plurality of arms each having a shaft with an engagement region moveable between a first, angled configuration relative to the shaft, and a second, straight configuration, with each engagement region having an inner surface shaped to mate with a stent holder. The alignment tool further includes a lock ring having a lumen configured to receive the plurality of arms, with the lock ring configured to slide over the arms between a first retracted position in which the engagement region of each arm is exposed and allowed to bias into the angled configuration, and a second locked position in which the lock ring extends over at least a portion of the engagement regions and compresses the engagement regions into the straight configuration. The alignment tool may also include a spring configured to bias the lock ring in the locked position.
