    摘要： Tissue-penetrating guidewires with shaped tips, and associated systems and methods are disclosed. A patient treatment system in accordance with one embodiment of the disclosure includes a tissue-penetrating guidewire that in turn includes a flexible segment having a distal portion and a proximal portion. The flexible segment is elongated along an elongation axis. A penetrating member is positioned at the distal portion and includes at least one blade segment having a tapered outer peripheral surface and an adjacent generally sharp edge. The blade segment extends to a distal end of the penetrating member to form a generally blunt tip. In operation, the guidewire can be connected to an electrical current source to deliver high frequency current to the penetrating member.

    摘要： Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes an elongated intravascular guidewire that includes a first branch and a second branch fixedly secured relative to the first branch at a first location and releasably secured relative to the first branch at a second location. At least one of the first and second branches is movable relative to the other between a first position in which the first and second branches form a closed shape, and a second position in which the first and second branches form an open shape. A controller can be operatively coupled to the first and second branches to control (e.g., in a fixed increment manner or a continuously variable manner) a distance between a portion of the first branch and a portion of the second branch while the first and second branches form the closed shape.

    摘要： Methods and systems for securing tissues, e.g., cardiovascular tissues, are disclosed. A method in accordance with one embodiment of the invention includes inserting a portion of a catheter into an opening between a first portion of cardiovascular tissue and a second portion of cardiovascular tissue. The method can further include drawing the first and second portions of the cardiovascular tissue into contact with each other by drawing a vacuum in a region adjacent to the first and second portions of cardiovascular tissue via the catheter while the catheter is positioned between the first and second portions. The tissue portions can be fused by heating the tissue from within the opening, e.g., via radio frequency energy. This technique, and associated catheter system, can be used to close a patent foramen ovale or other openings in cardiovascular tissue.

    摘要： A catheter for insertion into and treatment of tissue in a patient comprises a radio frequency (RF) electrode having an elongated body that conducts electrical RF energy to a conductive tip. An insulating sleeve surrounding the elongated body prevents leakage of RF energy from the elongated body when the catheter is being inserted into the tissue of the patient. In a first mode of operation, the conductive tip is exposed outside the insulating sleeve and the RF electrode delivers first RF energy capable of producing sparks that erode the tissue of the patient and create a tunnel through which the catheter can advance into the tissue of the patient. In a second mode of operation, the insulating sleeve is retracted to expose a portion of the RF electrode. Second RF energy is delivered to the volume of tissue around the catheter to necrotize the tissue by heating without producing sparks.
