Abstract: A system for treating mitral regurgitation may include an outer sheath having a lumen extending to a distal end of the outer sheath, an intermediate sheath slidably disposed within the lumen of the outer sheath, the intermediate sheath having a lumen extending to a distal end of the intermediate sheath, and an inner sheath slidably disposed within the lumen of the intermediate sheath, wherein the inner sheath includes a first anchor disposed within a lumen of the inner sheath, the first anchor being configured to penetrate and secure to a first papillary muscle. The intermediate sheath may include a tissue grasping mechanism at the distal end of the intermediate sheath, the tissue grasping mechanism being configured to hold and stabilize the first papillary muscle for penetration and securement of the first anchor to the first papillary muscle.

Abstract: A medical stent includes an expandable structure that is moveable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable structure in the expanded configuration defining a relaxed diameter. The expandable structure retains its relaxed diameter along portions of the expandable structure that are not constrained by contact with vessel walls after deployment. Portions of the expandable structure that are compressed by contact with vessel walls after deployment are caused to move to a reduced diameter less than the relaxed diameter along portions. The compressed portions of the expandable structure may help prevent plaque from breaking loose. Uncompressed portions of the expandable structure may allow blood flow therethrough.

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 medical device may include a main shaft extending from a proximal end to a distal end; an actuator at a proximal portion of the medical device; an end effector positioned at a distal end of the main shaft and comprising a first jaw and a second jaw; a motor; and a torque amplification system. The torque amplification system may include a driveshaft coupled to the motor; a spring coupled to the driveshaft and configured to expand or contract in a proximal or a distal direction relative to the driveshaft; a hammer moveably coupled to the driveshaft; and an anvil coupled to the end effector and abutting the hammer. The anvil may be configured to provide a rotational power output to the end effector to move the first jaw and/or the second jaw.

Abstract: A catheter system includes a catheter. The catheter includes a catheter tip and an ultrasound assembly at least partially positioned within the catheter tip. The ultrasound assembly includes a first optical fiber coupled to an optical-to-ultrasound transducer and a second optical fiber coupled to an ultrasound-to-optical transducer. The optical-to-ultrasound transducer is configured to generate an ultrasound signal in response to a pulsed optical signal. The ultrasound-to-optical transducer is configured to generate an optical signal in response to a received ultrasound signal.

Abstract: A mitral valve leaflet repair system may include a delivery catheter having at least one lumen extending proximally from a distal end of the delivery catheter, a plurality of anchor elements disposed within the at least one lumen, each of the plurality of anchor elements being configured to extend through one layer of mitral valve leaflet tissue, and a securing element configured to secure at least two of the plurality of anchor elements together on one side of the mitral valve leaflet tissue. The at least one lumen may include a suction lumen configured to grasp a mitral valve leaflet prior to extending the plurality of anchor elements through one layer of mitral valve leaflet tissue.

Abstract: A delivery catheter as disclosed herein may be configured in various embodiments to minimize the potential for entanglement between cardiac repair components such as between sutures and coupled anchors. In various embodiments this is achieved by separating an anchor translation channel from a suture translation channel while maintaining the coupling between the anchor and the suture.
