3 . The intracorporeal assembly according to claim 2 , wherein the tubular member comprises a radiopaque marker disposed near the tubular member distal end.
4 . The intracorporeal assembly according to claim 2 , wherein the elongate member has an elongate member length equal to or less than the tubular member length.
5 . The intracorporeal assembly according to claim 2 , further comprising a lubricious coating disposed on the tubular member.
6 . The intracorporeal assembly according to claim 2 , further comprising a lubricious coating disposed on the tubular member wall inner surface and the tubular member wall outer surface.
7 . The intracorporeal assembly according to claim 2 , further comprising a slit extending through the tubular member wall along a portion of the tubular member length.
8 . The intracorporeal assembly according to claim 2 , further comprising a slit extending through the tubular member wall along a distal portion of the tubular member length.
9 . The intracorporeal assembly according to claim 2 , further comprising a slit extending through the tubular member wall along a proximal portion of the tubular member length.
10 . The intracorporeal assembly according to claim 2 , further comprising a slit extending through the tubular member wall along an entire tubular member length.
11 . The intracorporeal assembly according to claim 3 , further comprising an eyeloop slidably engaged along the tubular member slit, wherein the eyeloop defines a eyeloop opening extending through the eyeloop.
12 . The intracorporeal assembly according to claim 11 , wherein the elongated shaft extends through the eyeloop opening.
13 . The intracorporeal assembly according to claim 2 , further comprising a gripping surface disposed on the tubular member near the proximal end.
14 . The intracorporeal assembly according to claim 1 , further comprising a guide catheter surrounding a portion of the tubular member disposed about the elongated shaft.
15 . A method comprising:
a) placing an elongate shaft having a proximal portion outside a subject vasculature and a distal portion within the subject vasculature;
b) expanding a balloon that is disposed on the distal portion within the subject vasculature;
c) moving a tubular member that is disposed about the elongate shaft from the proximal portion of the elongate shaft to the distal portion of the elongate shaft to surround a portion of the balloon.
d) removing the tubular member, balloon and elongate shaft from the subject vasculature.
16 . The method according to claim 15 , wherein the expanding a balloon further comprises lodging the balloon within the subject vasculature.
17 . The method according to claim 16 , wherein the moving a tubular member dislodges the balloon from the subject vasculature.
18 . The method according to claim 15 , wherein the removing the tubular member, balloon and elongate shaft are removed from the subject vasculature at the same time.
19 . The method according to claim 15 , wherein the moving a tubular member comprises moving a tubular member disposed about the elongate member from the proximal portion outside a subject vasculature to the distal portion to surround a portion of the balloon within the subject vasculature.
20 . The method according to claim 15 , further comprising placing the tubular member on the elongate shaft before placing the elongate shaft within the subject vasculature.
21 . The method according to claim 15 , further comprising placing the tubular member on the elongate shaft after placing the elongate shaft within the subject vasculature.
22 . The method according to claim 15 , wherein the moving a tubular member comprises moving a tubular member disposed about the elongate member from the proximal portion outside a subject vasculature to the distal portion to surround a portion of the balloon and collapse the balloon within the subject vasculature.
23 . The method according to claim 15 , wherein the moving a tubular member further comprises sliding an eyeloop slidably engaged in a longitudinal slit along a length of the tubular member in a proximal direction as the tubular member is moved in a distal direction along the elongate member, wherein the eyeloop defines a eyeloop opening extending through the eyeloop and the elongate member extends through the eyeloop opening.
24 . The method according to claim 15 , wherein the moving a tubular member further comprises moving a tubular member that is disposed about the elongate shaft and within a guide catheter from the proximal portion of the elongate shaft to the distal portion of the elongate shaft to surround a portion of the balloon.
