Abstract: Disclosed are various devices and methods for providing tissue access support. One exemplary device embodiment includes an elongated body having distal and proximal ends and extending along a longitudinal axis and defining a first lumen therein. A sealing member is coupled adjacent to the distal end of the elongated body and structured to seal to a first surface of a pericardial tissue. A support tube is provided having distal and proximal ends and extending along a longitudinal axis and defining a second lumen therein, wherein the support tube is slidably arranged in the lumen of the elongated body between first and second sliding positions. A securement member is coupled to the support tube and structured to engage at least a second opposing surface of the pericardial tissue. A guidewire is positioned in the second lumen of the support tube and includes a puncturing tip shaped to penetrate pericardial tissue.

Abstract: An implant for adding compliance to a blood vessel includes a first elongate rail shaped to contact an inner wall of a blood vessel and a second elongate rail shaped to contact an opposing inner wall of the blood vessel. Connectors extend between the first and second rails for providing a separation therebetween and maintaining the rails at locations on opposing sides of the lumen after implantation. The connectors push the rails outwardly for biasing the blood vessel toward a substantially oval shape. The connectors are preferably flexible for allowing the blood vessel to change shape during use for adding compliance to the blood vessel. The elongate rails are preferably curved or hemi-spherical for conforming to the shape of the inner wall of the blood vessel.

Abstract: A medical device includes a flexible catheter including a distal end, at least one lumen, and a longitudinal axis, an incision device coupled to the distal end of the catheter, and a distal tip coupled to and projecting from the incision assembly. The incision device comprises a wire that includes one or more electrodes for creating an incision through a pericardium. The wire has a first end fixed to an external surface of the distal tip and a second end extending through the distal opening of the distal tip. The wire is structured such that in a deployed configuration, (i) the portion of the wire extending from the first end of the wire to the distal opening of the body of the distal tip forms a shape comprising a protrusion extending relative to a longitudinal axis of the transcatheter and (ii) the electrode is positioned proximal to the protrusion.

Abstract: Systems and devices for accessing an inner space between two layers of tissues are provided. A system can include a helical coil within a catheter delivery system. The helical coil can be delivered to the treatment site at which point it can be turned to penetrate and traverse tissue to reach an inner space. The system can further comprise a gas supply system for providing gas to help displace one or both tissue layers to create more access space within the inner space. A tool, prosthetic, or other device can be transferred via the catheter system into the inner space to perform a procedure therein.

Abstract: Exemplary transection devices for making incisions through the pericardial membrane or parietal layer of the pericardium are described. These examples share the characteristic that they are deployed intravascularly through the RAA, IVC, SVC, or via a subxiphoid approach. One example is a pericardial tissue transection device comprising an elongated body with a proximal end and a distal end and extending along a longitudinal length. An incision assembly is coupled to the distal end of the elongated body. The incision assembly comprises an incision member having first and second ends each coupled to the incision assembly and aligned with the longitudinal length of the elongate body. At least a portion of the incision member is structured to reversibly extend laterally from the elongated body.

Abstract: Disclosed is a medical device comprising an incision assembly coupled to a catheter and an incision opening defined along the incision assembly. A retractable cutting apparatus is disposed within the incision opening and comprises a first incision member comprising at least one first cutting surface and defining a first member proximal end rotatably fixed proximate to a distal end of the incision opening and the at least one cutting surface is located on a bottom edge of the first incision member. A second incision member comprises at least one second cutting surface and defines a second member distal end attached to the first incision member at a connection point between a first member distal end and the first member proximal end of the first incision member, and wherein the at least one second cutting surface is located on a bottom edge of the second incision member.
