    摘要： Techniques are described for treating an occlusion in a patient. In one example, a system includes an atherectomy device configured to remove an occlusion from a body lumen and a positioning device that positions the atherectomy device adjacent to the occlusion. The positioning device includes a tubular body having first and second ends and defining a lumen therebetween, at least two fins engaged to the tubular body, wherein in a deployed state, the fins 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 extending through the lumen, and first and second stopper members, 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.

    摘要： An attachment mechanism and method for attaching or coupling a guide wire to a catheter for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The attachment mechanism generates friction forces against the guide wire to couple the guide wire to a catheter, which design permits a greater force to be used on the guide wire during a re-canalization procedure. The invention also encompasses use of the attachment mechanism in conjunction with active catheters, which have vibration-generating means to oscillate the distal end of the catheter or a component in the distal end of the catheter, to add vibration motion, preferably axial vibration motion, to the increased force that may be applied to the guide wire for purposes of penetrating an occlusion. The methods of the invention relate to methods of attaching the guide wire to the catheter and methods of treating a vessel having a partial or total occlusion.

    摘要： A wireguide set is provided for changing access between two access sites. The wireguide set includes a wireguide and a catheter. The wireguide passes through one access site while the catheter passes through another access site. The wireguide and catheter are connectable to each other inside the patient's body. Once connected, the catheter can pull the wireguide through the access site of the catheter. The wireguide set may be used to treat peripheral arterial disease occlusions in the lower leg where it is difficult or impossible to gain access through the occlusion from a femoral site.

    摘要： A method and systems for treating chronic total occlusions, particularly those that are difficult to treat, is disclosed. In this approach, recanalizing the CTO is achieved using a combined antegrade and retrograde approach. The proximal end of the occlusion is penetrated using an antegrade wire, using a traditional approach. Using collateral vessels, the distal end of the occlusion is crossed in a retrograde fashion and by appropriately maneuvering each member, a continuous channel is created. Additional elements such as capture devices, dilators and injection catheters are also disclosed.
