ABSTRACT:
The subject invention relates to a method and apparatus particularly suitable for use in dilating occluded blood vessels. The apparatus includes a tubular catheter having a balloon member connected to the distal end thereof. The balloon is initially located in an inverted manner with the free end thereof being connected to a reinversion member. A tubular sheath is telescopically mounted within the catheter surrounding said balloon member. In operation, the balloon member is everted by sliding the sheath beyond the distal end of the catheter. Fluid pressure can be utilized to facilitate eversion and to laterally expand the balloon member after it has been extruded through the occlusion. The sheath also aids in reinverting the balloon member.
