Abstract
The disclosure pertains to valvuloplasty devices which include a first outer shaft, a second inner shaft, a plurality of elongate members disposed therebetween and adapted to be expanded radially by relative motion between the first outer shaft and second inner shaft and a circumferential member disposed about the central portions of the plurality of elongate members, wherein the circumferential member is urged by radial expansion of the plurality of elongate members to contact the valve to be treated thereby effecting a valvuloplasty and methods of use therefor.

-
inserting a valvuloplasty device intravascularly into a patient, said valvuloplasty device comprising; an outer shaft; an inner shaft; a plurality of elongate members disposed between the distal end of the outer shaft and the distal end of the inner shaft and affixed thereto; and a circumferential member affixed to the plurality of elongate members and disposed between the distal end of the outer shaft and the distal end of the inner shaft; advancing the valvuloplasty device to a position within a valve to be treated; reducing a distance between the distal end of the outer shaft and the distal end of the inner shaft thereby causing a central portion of the plurality of elongate members disposed between the distal end of the outer shaft and the distal end of the inner shaft to expand to a radially expanded configuration and press the circumferential member against the valve to be treated; increasing the distance between the distal end of the outer shaft and the distal end of the inner shaft thereby causing the central portion of the plurality of elongate members disposed between the distal end of the outer shaft and the distal end of the inner shaft to contract radially; removing the valvuloplasty device from the patient in a radially contracted configuration in which the distal end of the inner shaft extends distally beyond the distal end of the outer shaft and the plurality of elongate members disposed between and operably connected to the inner shaft and the outer shaft are generally parallel to a longitudinal axis of the inner shaft. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
