Abstract: Examples of transection devices are disclosed. One example includes an elongated body having a U-shaped notch, wherein the U-shaped notch includes a wall surface extending from a surface of the elongated body and an upper extension extending from the wall surface substantially parallel with the longitudinal axis of the elongated body. An incision member located in the U-shaped notch preferably extends from the elongated body toward the extension of the U-shaped notch at an angle. The incision member is well suited for cutting pericardial tissue as it passes through the U-shaped notch.

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: 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.
