Abstract: A biostimulator delivery system having a tether cable, is described. A connector can be mounted on the tether cable to connect to a biostimulator. The connector can be a protuberance that lodges within the biostimulator, or a threaded connector that screws into the biostimulator. The tether cable has a stranded cable configuration, including several strands extending about a core strand in a helical direction. The stranded cable structure resists breaking under bending stresses typically seen during a tether mode used during delivery of the biostimulator. The tether cable reliably secures the biostimulator to the delivery system in the tether mode. Other embodiments are also described and claimed.

Abstract: A biostimulator transport system includes a biostimulator coupling along a central axis, and one or more location guides. The location guides are deployable radially outward from the central axis. When deployed, the location guides engage anatomical landmarks. Other embodiments are also described and claimed.

Abstract: A loading tool for loading a collapsible prosthetic heart valve into a delivery device may include a body extending in a longitudinal direction between a proximal end and a distal end, an extension on the distal end of the body, and a slot extending through the extension from a free end of the extension toward the distal end of the body. The body may include a lumen extending between the proximal end and the distal end, the body lumen having a first diameter. The extension may have a lumen coaxial with the body lumen, the extension lumen having a second diameter less than the first diameter so as to define a shelf surface between the proximal end of the body and the free end of the extension.

Abstract: A prosthetic heart valve having an inflow end and an outflow end includes a collapsible and expandable stent having a plurality of commissure features, a plurality of first struts and a plurality of second struts. The plurality of first struts define a substantially cylindrical portion and the plurality of second struts have first ends attached to the cylindrical portion and free ends projecting radially outward from the cylindrical portion and configured to couple to adjacent heart tissue to anchor the stent. A collapsible and expandable valve assembly disposed within the stent has a plurality of leaflets coupled to the commissure features.

Abstract: A prosthetic heart valve having an inflow end and an outflow end includes a stent having a collapsed condition, an expanded condition, and a plurality of cells arranged in circumferential rows. The stent may include one or more securement features. One securement feature may be an anchor arm having a body portion and a free end extending from the body portion, the body portion being coupled to a perimeter of one of the plurality of cells, with the free end extending toward the inflow end in an expanded condition of the anchor arm. Another securement feature may include a flange formed of a braided mesh and having a body portion coupled to the stent and a flared portion adjacent the inflow end of the prosthetic heart valve. A valve assembly is disposed within the stent and has a plurality of leaflets.

Abstract: A delivery device and method for deploying a stent-graft within a body lumen of a patient are provided. According to one embodiment, the delivery device includes a tubular member lock that couples an outer tubular member of the device with an inner tubular member, such that as the outer tubular member is retracted to deploy the stent-graft, the distal-most end of the delivery device is also retracted. In one embodiment, the delivery device also includes a stent lock disposed on an intermediate tubular member that is configured to releasably couple the stent-graft and the intermediate tubular member. The inner tubular member and the outer tubular member are configured to be coupled to one another such that movement of the outer tubular member results in movement of the inner tubular member with respect to the intermediate tubular member so as to deploy the stent-graft.
