Abstract: A replacement heart valve implant includes an expandable framework including a commissure post and defining a central lumen, and a valve leaflet disposed within the central lumen, the valve leaflet including a mounting tab secured to the expandable framework at the commissure post. The commissure post is configured to hold the mounting tab in compression. A tool for assembling a replacement heart valve implant includes a tool body comprising first and second body portions, first and second handle portions extending from the body portions, and first and second post engagement arms extending from the body portions. Translation of the first handle portion toward the second handle portion translates the first post engagement arm away from the second post engagement arm.

Abstract: A replacement heart valve system may include a replacement heart valve implant including an expandable framework configured to shift from a radially collapsed to a radially expanded configuration, wherein the framework is self-biased toward the radially expanded configuration, and a plurality of valve leaflets attached to the framework. The replacement heart valve system may include an implant delivery system including a handle and an elongate shaft assembly including a tubular member fixedly attached to the handle, and an implant holding portion configured to constrain the framework in the radially collapsed configuration. The elongate shaft assembly includes an expandable balloon disposed on the tubular member within the implant holding portion, the balloon being configured to shift between deflated and inflated configurations. When the framework is constrained within the implant holding portion, at least a portion of the framework extends distal of the balloon in the deflated configuration.

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 implantable medical device adapted to be implanted at an implantation site may be capable of being implanted in more than one rotational orientation at the implantation site. The implantable medical device includes an expandable body that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, and a radiopaque indicator that is disposed relative to the expandable body. The radiopaque indicator is adapted to be have a first appearance if viewed in a first rotational orientation and a second, different appearance if viewed in a second rotational orientation that is different from the first rotational orientation. As an example, the implantable medical device may be a catheter-delivered replacement aortic valve.

Abstract: A device for radially compressing a stent may include a housing including a central opening and a first iris positioned adjacent the housing. The first iris includes a first circumferential ring and a first plurality of arms extending radially inward from the first circumferential ring to define a first central opening. The device may include a second iris axially offset from the first iris and including a second circumferential ring and a second plurality of arms extending radially inward from the second circumferential ring to define a second central opening. Rotation of the circumferential ring(s) relative to the housing changes a size of their respective central opening(s). The plurality of arms may shift between a first configuration and a second configuration via rotation of the circumferential ring(s) relative to the housing.

Abstract: A replacement heart valve implant may include an expandable framework having a plurality of frame struts defining a lattice structure, each frame strut having a thickness in a radial direction from a central longitudinal axis; and a plurality of valve leaflets coupled to the expandable framework. The plurality of frame struts defines a lower crown proximate an inflow end of the lattice structure and upper crown proximate an outflow end of the lattice structure and a plurality of stabilization arches extending downstream from the outflow end of the lattice structure. The lattice structure includes a first circumferential row of x-connectors upstream of the upper crown and a second circumferential row of x-connectors downstream of the lower crown. The thickness of at least some frame struts connecting the first and second circumferential rows of x-connectors is less than the thickness of other frame struts of the plurality of frame struts.

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.
