Abstract: Various mechanically expandable prosthetic heart valves, as well as deliver apparatus, delivery assemblies, and methods for implanting such prosthetic heart valves. In one example, a prosthetic heart valve includes a mechanically expandable frame, a valve structure, and an actuator. The frame includes a plurality of struts and is movable between a radially compressed state and a radially expanded state. The valve structure includes a plurality of leaflets. The actuator is coupled to the frame and comprises an actuation lumen, a locking member, and a locking element. The actuation lumen is circumferentially spaced and axially parallel to the locking member. The actuation lumen is configured for receiving an axially movable actuation shaft that can move the frame between the radially compressed state and the radially expanded state. The locking element is rotatably coupled to the locking member and is configured to lock the frame at a desired state.

Abstract: A device may provide a fluid connection between fluid vessels, such as between an inferior vena cava and an abdominal aorta. The device may include a conduit structure for deployment in a first fluid vessel or a shunt structure for deployment within a passage between the first fluid vessel and a second fluid vessel that is adjacent to the first fluid vessel. The conduit structure may include a narrowed section to which the shunt structure is secured and in fluid connection therewith.

Abstract: Disclosed herein are reinforced expandable introducer sheaths and methods of using the same. The sheaths minimize trauma to the patient's vasculature by including a reinforcing member to improve the push force of the sheath while reducing the chances of kinking during delivery of a prosthetic device. The sheath can include a plurality of expandable rings aligned along the longitudinal axis of the sheath and coupled together to form an elongated tubular structure. The sheath can also include a plurality of radial members circumferentially arranged to form a tubular support structure. The radial members slidingly interconnected around the circumference of the tubular structure to facilitate radial expansion of the sheath.

Abstract: The expandable sheath and methods of use disclosed herein are used to deliver a prosthetic device through a patient's vasculature. The sheath is constructed to be expandable in the circumferential direction, while maintaining sufficient stiffness in the longitudinal direction to withstand pushing and resist kinking. The sheath includes a plurality of curved arms extending outwardly from a longitudinally extending spine. The curved arms move away from the longitudinal axis of the sheath when pushed radially outwardly by a passing prosthetic device, and move back toward the longitudinal axis once the prosthetic device has passed.

Abstract: Ultrasound probe systems and methods for using an ultrasound probe to assist during treatment of conditions of the human heart are provided. The method may comprise loading a medical instrument into a guide fastened to the ultrasound probe. The ultrasound probe may be inserted into a patient by way of an incision. The distal end of the ultrasound probe may be navigated to a location adjacent to an exterior surface of the heart. A treatment site may be identified on the exterior surface of the heart based on images obtained from an ultrasound transducer disposed within a distal end of the ultrasound probe. The medical instrument may be advanced within the guide to the treatment site and the medical instrument used for treatment. After treatment, the medical instrument may be withdrawn from the treatment site.

Abstract: An anchoring system and related methods are provided for treatment of dilated hearts and of functional valve regurgitation, the system comprising one or more self-expandable or manually expandable anchors and associated devices for fixating a valve splint within the heart. For example, a spade-shaped assembly may be configured to be deployed in a right ventricle of the heart and to stabilize a puncturing instrument to puncture the septum. Various puncturing instruments may also be part of the anchoring system, including one or more of a flexible needle having a multiplicity of slits disposed along the length of the needle, a trocar catheter with a retractable head, and a catheter needle having a blunt introducer to protect nearby tissue within the heart during advancing a guidewire. A cutter catheter and puncture location catheter may also be part of the system and be used during treatment.
