  • Publication number: 20250057594
    Abstract: The disclosure provides an elongate tissue dissection and removal catheter having a length and defining a longitudinal axis along the length of the catheter. The tissue dissection and removal catheter includes an outer tubular member having a proximal end, a distal end, and defining an elongate passage therethrough along its length, and a subassembly slidably disposed in the elongate passage of the outer tubular member. The subassembly includes first and second deployable stabilizers configured to expand in lateral width along a direction transverse to the longitudinal axis when unconstrained by the outer tubular member. Each stabilizer can define a curved free distal end that is configured to be received within a cusp of a respective cardiac valve leaflet.

  • Publication number: 20220117735
    Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An illustrative annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. An improved protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.
