Claim Text:
1. A catheter having a distal region and a proximal region, comprising: an elongate shaft extending from the distal region to the proximal region and defining a lumen therebetween; means for occluding a body vessel disposed over a portion of the distal region of the elongate shaft, the means for occluding the body vessel being longitudinally translatable along the elongate shaft and being unsecured to the elongate shaft; and means for activating the means for occluding the body vessel disposed over the elongate shaft, wherein the means for occluding the body vessel is reversibly movable between a first position in which the means for occluding the body vessel has a first length and a second position in which the means for occluding the body vessel has a second length that is less than the first length, wherein the means for occluding the body vessel bas a first diameter at the first position and a second diameter at the second position, where the second diameter is greater than the first diameter, wherein the means for occluding the body vessel comprises a distal portion, a proximal portion and an intermediate portion, and the means for occluding the body vessel is configured such that at least the intermediate portion is displaced radially outwardly when moving from the first position to the second position, and wherein the means for occluding the body vessel is configured such that the distal portion of the means for occluding the body vessel rotates with respect to the proximal portion of the means for occluding the body vessel in moving from the first position to the second position.
