  • Publication number: 20190298510
    Abstract: Medical systems, devices and methods for creation of autologous tissue valves within a mammalian body are disclosed. One example of a device for creating a valve flap from a vessel wall includes an elongate tubular structure having a proximal portion and a distal portion and a longitudinal axis; a first lumen having a first exit port located on the distal portion of the elongate tubular structure; a second lumen having a second exit port located on the distal portion of the elongate tubular structure; a recessed distal surface on the distal portion of the elongate tubular structure, wherein the recessed distal surface is located distally to the first exit port; and an open trough on the recessed distal surface extending longitudinally from the first exit port.

  • Patent number: 9949752
    Abstract: The present application pertains generally to medical systems and methods for creation of an autologous tissue valves within a mammalian body. In some embodiments, a system for creating an endoluminal valve from a blood vessel wall is provided. The system includes a tubular assembly having a longitudinal axis, a proximal end, a distal portion with a distal end, and a first lumen extending from the proximal end to a distal port located proximate the distal portion. The distal portion can have a supporting surface that extends in a longitudinal direction and is offset from a surface of the tubular assembly proximal the distal port. The system can further include a tissue dissection probe disposed within the first lumen.
