    摘要： An introducer sheath for the insertion of a medical device into a blood vessel having an expandable sheath. The sheath has a length, a thickness, and proximal and distal ends. The expandable sheath has a frame extending longitudinally between the proximal and the distal ends, and having an exterior surface and an interior surface that forms an interior lumen along the length of the frame. The frame is configured to achieve an expanded state and a contracted state, the expanded state forming an expanded cross-section in the lumen for passing a medical device therethrough. The frame has a smooth coating about the exterior surface and protrusions extending into the lumen along the interior surface. The introducer sheath can be introduced into a patient in the contracted state, with the distal end of the introducer sheath prevented from moving in the proximal direction by an abutment against a dilator end surface.

    摘要： A sutureless securing device for securing on an opening in a ventricular wall, includes: a hollow main body with an outer surface; a ring received at a first end of the hollow body, this ring being mobile along part of the outer surface of the hollow body; a tubular membrane covering the outer surface, whilst extending between the ring and the second end of the hollow body; a distal end of this tubular membrane, placed on the side of this second end, being self-expandable between a first configuration in which it has a tubular form, and a second configuration in which it defines a first flange extending radially, starting from the hollow body; the other end of this tubular membrane being able to be deformed by the displacement of the ring, such as to form a retention flange, the position of which can vary relative to the first flange.

    摘要： The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes interatrial shunting systems that include a shunting element having a lumen extending therethrough that is configured to fluidly couple the left atrium and the right atrium when the shunting element is implanted in a patient. The system can also include an energy receiving component for receiving energy from an energy source positioned external to the body, an energy storage component for storing the received energy, and/or a flow control mechanism for adjusting a geometry of the lumen.
