Abstract:
1. A method of applying vascular therapy to a wall of a body vessel, the method comprising: introducing a medical device attached to a distal end of a catheter in a compressed configuration into a body vessel and traversing through the body vessel to a point of treatment, the medical device comprising a tubular frame defining a lumen about a longitudinal axis, the tubular frame having a distal end, a proximal end, and a middle region therebetween, the middle region of the tubular frame including a plurality of members with slots therebetween, where the middle region of the tubular frame is moveable from a compressed configuration to an expanded configuration, where in the compressed configuration the members lie in immediate contiguous proximity to each other, and in the expanded configuration each of the members comprises two bends and a contacting portion therebetween, the contacting portion displaced radially outward from the longitudinal axis to form interstices between adjacent members, and a sleeve encompassing a portion of only the contacting portion of the members of the middle region of the tubular frame, radially expanding the members of the middle region of the tubular frame from the compressed configuration to the expanded configuration so that the contacting portion of the members is placed in close proximity to the body vessel wall and the sleeve is urged to contact the wall of said body vessel; and maintaining the sleeve in contact with the wall of said body vessel to apply vascular therapy at the point of treatment within the body vessel, where the point of treatment comprises a lacerated hole extending laterally through the entire wall of said body vessel, the sleeve covering the entire lacerated hole to promote hemostasis when the sleeve is in contact with the wall of said body vessel, while the interstices permit fluid flow to areas distal to the point of treatment, the catheter remaining attached to said medical device while the fluid flows through the interstices.
