DEVICE FOR PERFORMING TRICUSPID REGURGITATION OPERATION
20220265255 · 2022-08-25 ·

A device for performing tricuspid regurgitation operation is proposed. The device for performing tricuspid regurgitation operation is easily inserted through the inferior vena cava, the tricuspid valve, and the pulmonary artery in sequence in order to treat tricuspid regurgitation (TR) which is a disease where blood from the right ventricle flows back into the right atrium through an empty space (i.e., orifice) formed by incomplete closing of the tricuspid valve (TV) which is positioned between the right atrium and the right ventricle of the heart. The device includes: a fixing member for pulmonary artery installed in the pulmonary artery; a fixing member for inferior vena cava installed in the inferior vena cava; a connecting tube connecting the fixing member for the pulmonary artery and the fixing member for the inferior vena cava to each other; and a blocking part passing obliquely through the tricuspid valve.

DEVICES, SYSTEMS, AND METHODS FOR RESHAPING A HEART VALVE ANULUS, INCLUDING THE USE OF A BRIDGE IMPLANT HAVING AN ADJUSTABLE BRIDGE STOP

Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial adjustability and retrievability years after implant. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilise an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.

PERCUTANEOUS ARTERIAL ACCESS TO POSITION TRANS-MYOCARDIAL IMPLANT DEVICES AND METHODS

A system for treating a heart includes a catheter that is advanceable into a chamber of the heart and that is repositionable within the chamber between a septal wall and an external wall to enable penetration of the septal and external walls via a needle that is disposed within a lumen of the catheter. A first guidewire is deliverable through the penetration of the septal wall so that a distal end of the first guidewire is disposed within another chamber of the heart. A second guidewire is deliverable through the penetration of the external wall so that a distal end of the second guidewire is disposed externally of the external wall. The first guidewire is connectable to the second guidewire to join or form a path within the chamber that extends between the septal wall and the external wall.

Fracturing calcifications in heart valves
09717513 · 2017-08-01 · ·

A device for fracturing calcifications in heart valves including a catheter (12, 22, 42) configured for percutaneous delivery to a heart valve, an fracture-producing element (14, 26, 46, 64, 66,82, 124, 152) disposed at a distal portion of the catheter and operative to vibrate and mechanically fracture calcifications when brought into contact with a calcification at a leaflet of the heart valve, and an energy source (34, 47, 79, 98, 152) operative to vibrate the fracture-producing element so that the fracture-producing element fractures the calcification without necessarily removing the calcification from the leaflet. The device may further comprise a valvuloplasty balloon (30), an embolic protection net (56) and a protective sleeve (110, 130).

Heart valve sealing devices and delivery devices therefor

An implantable prosthetic device includes a coaption portion, paddles, and clasps. The paddles are moveable from a closed position to an open position. The clasps are also moveable from an open position to a closed position. The implantable prosthetic device can be used to repair a native valve, such as a native mitral valve. Other embodiments are also described.

Apparatus and methods for alignment and deployment of intracardiac devices

Apparatus and methods are described herein for use in the alignment and deployment of a prosthetic heart valve, such as a mitral valve. In some embodiments, an apparatus includes a tube assembly and a needle assembly configured to be received through a lumen of an outer tube member of the tube assembly. The needle assembly includes an elongate needle having a distal tip configured to be inserted through the epicardial surface of a heart. An imaging probe is coupled to a coupling member and includes an imaging element. The imaging probe is configured to provide image data associated with a location of a commissural-commissural (C-C) plane and a location of the anterior-posterior (A-P) plane of the mitral valve and the annular region of the heart such that a prosthetic mitral valve can be positioned within the heart based at least in part on the C-C plane and the A-P plane.

Tissue anchor and anchoring system

A tissue anchor includes an anchor member formed from a generally flexible material. An activation member, which may be a tensioning member, causes proximal and distal end portions of the anchor member to move toward each other into a shortened configuration suitable for anchoring against the tissue. The tissue anchor can optionally be deployed and activated using a catheter device.

Visualization devices for use during percutaneous tissue dissection and associated systems and methods

A device and method for visualization of the intravascular creation of autologous valves, and particularly venous valve, is disclosed herein. One aspect of the present technology, for example, is directed toward a delivery catheter that can include a lumen configured to receive a dissection assembly and a trough having a plurality of transducers electrically coupled to a proximal portion of the delivery catheter. At least one of the transducers can be configured to emit a signal towards a portion of a blood vessel adjacent the trough, and at least one of the transducers can be configured to receive a reflection of the emitted signal.

Methods and apparatus for atrioventricular valve repair

Methods and devices are disclosed for minimally invasive procedures in the heart. In one application, a catheter is advanced from the left atrium through the mitral valve and along the left ventricular outflow tract to orient and stabilize the catheter and enable a procedure such as a “bow tie” repair of the mitral valve. Right heart procedures are also disclosed.

Aortic insufficiency valve percutaneous valve anchoring

An anchoring device for use within a cardiovascular structure includes an expandable ring having a central axis extending in a longitudinal direction. At least one leg extends from the ring in the longitudinal direction. The leg includes a first end connected to the ring and a free end, with at least one anchor connected to the leg. The anchoring device may be used to anchor a transcatheter heart valve within the cardiovascular structure.
