Abstract: An angioplasty apparatus for facilitating accurate placement of a lumen stent for dilating a stenosis, the apparatus includes arcuate low pressure balloon segment(s) connected at a distal end of a guiding catheter with gap(s) to facilitate blood flow during a stenting procedure. Optimal positioning of a stent at a lumen bifurcation is facilitated to obviate any tendency of a stent to miss a proximal end of a stenosis branch lumen while concomitantly preventing the stent from protruding into an original lumen, such as a patient's aorta.

Abstract: An angioplasty apparatus and method, with a self-expanding stent, for facilitating accurate placement of the self-expanding stent for dilating a patient's blood lumen stenosis, the apparatus includes arcuate, low pressure, balloon segment(s) connected at a distal end of a deployment catheter assembly with axial gap(s) to facilitate continuous blood flow during a stenting procedure.

Abstract: An angioplasty apparatus and method including a balloon stent, for facilitating accurate placement of a lumen stent for dilating a stenotic site, the apparatus includes arcuate, low pressure, anchor and/or marker and guide balloon segment(s) connected to a stent deployment catheter at at least one of a proximal and distal end of a wire mesh stent with circumferential gaps in the anchor and/or marker balloon segment or segments to facilitate blood flow and contrast media during a stenting procedure. Optimal positioning of a stent at a stenotic lumen site is facilitated by selective injection of marker fluid into one or more low pressure, anchor and/or marker balloon segment(s).
