摘要：
The present disclosure provides medical devices for creating a channel in a biological soft tissue. The devices comprise an integral rotatable tool formed by an elongated distal member and a proximal shaft, the elongated member having a distal end portion and a proximal end portion, the distal end portion comprising a tissue piercing tip of a pyramid-like shape, and the proximal end portion comprising an elongated prism-like portion having at least three surfaces and respective prism edges, with at least one of the prism edges between the surfaces being configured as a tissue cutting blade, and the proximal shaft interfacing and extending from the prism-like portion and having a cross section larger than a cross section of the prism-like portion at the interface. In some embodiments, the device comprises an intermediate portion extending between the distal end portion and the proximal end portion and having a frustum shape, thereby forming a smooth transition between a base portion of the tissue piercing tip and the proximal end portion.
