Abstract: Mechanisms are disclosed for securing a catheter in place to facilitate puncturing a hole through a vessel wall. The securing mechanisms include mechanically releasing arms that press against the wall of the vessel. The mechanically releasing arms are advanced out of the catheter. Outside of the catheter, the securing mechanisms angle or curve toward the vessel wall to contact the wall. The more the mechanically releasing arms are advanced, the closer the approach to the wall and the more force placed against the wall to anchor the catheter in place. The mechanically releasing arms include a plurality of wires that angle or curve toward the vessel wall when deployed, one or more wires that coil away from the catheter to contact the vessel wall when deployed, or a stopper arm with a curved endcap that contacts the vessel wall when deployed.

Abstract: Mechanisms are disclosed for securing a catheter in place to facilitate puncturing a hole through a vessel wall. The securing mechanisms include bubbles, meshes, flaps, or similar features that expand when activated to press against the wall of the vessel (e.g., coronary sinus). Activation of the securing mechanisms occurs through removal of a restraint (e.g., a cover) or by pushing or pulling a wire. The securing mechanisms activated by removal of a restraint may self-expand or may expand due to a spring within a mesh structure. The securing mechanisms activated by pushing or pulling a wire expand due to movement of the wire itself or due to movement of a component attached to the wire and to the anchor member.

Abstract: A delivery system includes a suture attachment mechanism for maintaining a connection to a heart valve after initial deployment, thereby allowing recapture of the heart valve if desired. A plurality of suture portions is provided along a distal end portion of the delivery system, each suture portion having a first end fixed to the delivery system and a second end releasably coupled to a retention member on the delivery system. A knob on a handle of the delivery system is actuated for causing the second end of each suture portion to be released from its respective retention member, thereby allowing the suture portions to be decoupled from the heart valve. The suture portions are located only along a distal end portion of the delivery system for improving reliability and consistency.

Abstract: A shunt comprises a central flow portion configured to fit at least partially within an opening in a tissue wall. The tissue wall is situated between a first anatomical chamber and a second anatomical chamber and the opening represents a blood flow path between the first anatomical chamber and the second anatomical chamber. The central flow portion is further configured to maintain the blood flow path from the first anatomical chamber to the second anatomical chamber. The shunt further comprises a barrier configured to alter growth of tissue around the shunt.

Abstract: Apparatuses, systems, and methods for prosthetic valves. An implantation site may comprise a native heart valve or another implantation site in examples. Examples may be utilized for improved anchoring and sealing of flow (e.g., paravalvular leakage) with a native heart valve having calcification. Examples may include breaking up calcification of a native heart valve to improve deployment to the native heart valve.

Abstract: An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. The implantable device can be removed using one or more of a cutting device, a capture device, and a stabilization component. The stabilization component can control the position of the implantable device while the cutting device resects one or more of the leaflets to which the implantable device is engaged.

Abstract: Examples of the present disclosure may be directed to reducing a tension force or a compression force in one or more shafts of the delivery system. An elongate catheter may include the one or more shafts. The tension force or compression force may result from residual tension or compression in a shaft resulting from movement of the shaft. The tension force or compression force may alternatively or in combination result from interacting forces across a plurality of the shafts. The tension force or compression force may hinder the operation of the delivery system and in instances may damage the delivery system. Systems, devices, and methods for reducing the tension force or compression force are disclosed herein.

The tissue wall is situated between a first anatomical chamber and a second anatomical chamber and the opening represents a blood flow path between the first anatomical chamber to the second anatomical chamber. The central flow portion is further configured to maintain the blood flow path from the first anatomical chamber to the second anatomical chamber, prevent in-growth of tissue within the opening, and expand in response to expansion of the tissue wall.
