摘要： The invention relates to a catheter assembly for slitting a dissection membrane (4) of an aorta of a patient. The assembly comprises a first catheter (2) configured to be inserted into a true lumen (6) located on a first side of the dissection membrane (4), a second catheter (8) configured to be inserted into a false lumen (10) located on a second side of the dissection membrane (4), and an electrically conductive wire (12) configured to be arranged to be electrically conductively joined to the first catheter (2) and the second catheter (8). The wire (12) is further configured to be energized with electrical current such that the dissection membrane (4) can be slit by the wire (12). Also described is a method of slitting a dissection membrane (4) of an aorta of a patient, comprising the steps of (a) arranging a first catheter (2) to extend at least partially within a true lumen (6) of the aorta located on a first side of the dissection membrane (4), (b) arranging a second catheter (8) to extend at least partially within a false lumen (10) of the aorta located on a second side of the dissection membrane (4), (c) arranging an electrically conductive wire (12) so as to be electrically conductively joined to the first catheter (2) and the second catheter (8), (d) applying an electrical current to the wire (12); and (e) slitting the dissection membrane (4) by moving the wire (12) relative to the dissection membrane (4).

摘要： Devices including, but not limited to, a self-expandable member having a proximal end portion and a main body portion are disclosed. The self-expandable member is movable from a first delivery position to a second placement position, in the first delivery position the expandable member being in an unexpanded position and having a nominal first diameter and in the second position the expandable member being in a radially expanded position and having a second nominal diameter greater than the first nominal diameter for deployment within a vessel or duct of a patient. The expandable member includes a plurality of cell structures with the cell structures in the main body portion extending circumferentially around a longitudinal axis of the expandable member and the cell structures in the proximal end portion extending less than circumferentially around the longitudinal axis of the expandable member. At least some of the struts have one or more wires or ribbons (661, 662, 663) wound thereabout so as to enhance the average deflection stiffness.

摘要： An intravascular catheter device is provided for use during a surgical procedure. The catheter device includes a catheter tube having an expandable portion with a plurality of struts each defining an outer surface. The expandable portion is operable between a closed position, wherein the expandable portion has a first diameter, and an opened position, wherein the expandable portion has a second diameter that is larger than the first diameter. An incising element is provided on the outer surface of at least one of the struts. The incising element has a sharpened edge that extends outwardly in a radial direction from the outer surface of the strut for creating an incision in atherosclerotic material located within a blood vessel when the expandable portion is in the opened position.

摘要： Techniques are described for treating an occlusion in a patient. In one example, a system comprises an atherectomy device (10) configured to remove an occlusion from a body lumen and a positioning device (50,80) that positions the atherectomy device adjacent to the occlusion. The positioning device comprises a tubular body (52) having first and second ends (56,58) and defining a lumen (60) therebetween, at least two fins (54A,54B,54C) engaged to the tubular body, wherein in a deployed state, the fms extend radially outward from the tubular body, and wherein in an undeployed state, the at least two fins wrap about one another and about the tubular body, a guide wire (62) extending through the lumen, and first and second stopper members (66A,66B), each of the first and second stopper members engaged to the guide wire, wherein the first stopper member and the second stopper member substantially prevent movement of the tubular body along the guide wire.
