摘要： Devices including, but not limited to, a self-expandable member having a proximal end portion and a main body portion. 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.

摘要： The present invention provides an obstruction removing device and a method for making the obstruction removing device. The method includes two mandrels with an elongate element being wound around the first mandrel and then wrapped around the second mandrel. The mandrels are movable relative to one another so that the second mandrel may be moved closer to the first mandrel after winding the element around the first mandrel and before winding the element around the second mandrel.

摘要： A device including a self-expandable member having a proximal end portion and a main body portion. 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. In one implementation the cell structures have dimensional and material characteristics that result in about a −1.5N to a about a −3.5N overall reduction in radial force along the length of the expandable member per millimeter of expansion during about an initial 0.50 mm diametric range of expansion from the nominal diameter and that results in about a −0.10N to about a −0.50N overall reduction in radial force along the length of the expandable member per millimeter of expansion during subsequent diametric ranges of expansion.

摘要： A device including a self-expandable member having a proximal end portion and a main body portion. Each of the self-expandable portions consists of a plurality of cell structures formed by intersecting strut members. In one implementation, at least one proximal cell structure in the proximal end portion has one or more struts that have a width and/or thickness greater than the width and/or thickness of the majority of strut members in the main body of the expandable member. In another implementation at least some of the intersecting strut members have a thickness to width ratio of greater than one. Attached to at least one of the proximal-most cell structures in the proximal end portion is a proximally extending flexible wire having sufficient length and flexibility to navigate the tortuous vasculature of a patient. In another implementation, the device is delivered to the treatment site through the lumen of a delivery catheter.
