Abstract: Systems for imparting pulsatile energy to cardiovascular tissue are provided. Aspects of the systems include a console assembly comprising a potential source, a manifold assembly operably connected to an output of the console assembly, wherein the manifold assembly comprises an oscillator configured to generate pulse energy from energy transmitted from the potential source and a catheter assembly operably connected to an output of the manifold assembly.

Abstract: Pulsatile balloon catheter systems are provided. Aspects of the systems include: a pulse generator; and a balloon catheter assembly operably connected to the pulse generator. In embodiments, the balloon catheter assembly includes: a proximal connector operably connecting the balloon catheter assembly to the pulse generator and configured to transduce a first pulse energy generated by the pulse generator to a second pulse energy; a distal balloon; and a catheter component, where the catheter component includes a fluidic passage operably positioned between the proximal connector and the distal balloon, which passage is configured to propagate the second pulse energy from the proximal connector along the fluid passage to the distal balloon. Also provided are balloon catheter assemblies and kits that include the same. Also provided are systems and methods for assessing vessel compliance in-vivo. Also provided are systems and methods for determining system state of balloon catheter systems.

Abstract: A method and apparatus provide techniques for stenting ostial legions and other restenosis in vessels through a stenting apparatus that includes both a guidewire and a separate marker wire. In some examples, the marker wire is threaded through a tubular body of the stenting apparatus and in other examples, the marker wire may be threaded externally through the tubular body. In both such examples, the marker wire may be aligned with a radiopaque marker of the apparatus to guide marker wire positioning.

Abstract: An angioplasty balloon catheter with an added channel for delivering medication or removing body fluids distal to the site of angioplasty is disclosed. The balloons are especially useful in the treatment of occlusions in saphenous vein grafts, the coronary and carotid arteries, arteries arising from the aorta and branches thereof and in veins flowing to the heart or their tributaries and sub tributaries thereof.

Abstract: An apparatus for interventional treatment of atherosclerosis at a vascular bifurcation includes structure for receiving a first guidewire and a second guidewire. An exit for the second guidewire is located in a central section of the structure. A first balloon portion is secured to the structure so a proximal end is located adjacent the exit. A second balloon portion is secured to the structure so a distal end is located adjacent the exit on a side of the exit opposite the first balloon portion. An annular gap is defined between the proximal end of the first balloon portion and the distal end of the second balloon portion. The annular gap, at a radial outermost location relative to the structure, has a width that is equal to or less than a width of the annular gap at a radially innermost location relative to the structure. The apparatus also includes an expandable stent that is mountable about the first and second balloon portions.

Abstract: An apparatus for use with an expandable stent having oppositely disposed first and second terminal edges. The apparatus has a catheter shaft with a lumen, and an inflatable balloon with oppositely disposed first and second end portions and an internal chamber. The internal chamber is in fluid communication with the lumen of the catheter shaft, and receives inflation fluid to inflate the balloon. The balloon has cylindrical inner and outer surfaces that extend between the end portions. The cylindrical inner surface is secured to the catheter shaft at first and second attachment sites adjacent the first and second end portions, respectively. At least one of the first and second end portions of the balloon has a toroidal shape defined by an arcuate end surface that intersects the cylindrical inner and outer surfaces at a common radial plane. A respective one of the attachment sites is located adjacent the one end portion lying adjacent the common radial plane.

Abstract: Perfusion guard is a first of a new generation of devices for interventional cardiology. It encompasses an improved debris collection system with a novel perfusion system. It uses an occlusive balloon to provide total protection from debris from interventional procedures. Distal perfusion is maintained using a variety of endogenous or exogenous perfusion substances delivered through an isolated lumen. These substances may be the patients' blood, artificial blood substitutes or biocompatible perfusion fluids. A therapeutic device or catheter may be introduced through a separate port or may be modified to be delivered over the device. Thus the device provides a safe and improved means of carrying out interventions while protecting from debris generated from these procedures and maintaining perfusion to the segments beyond the site of intervention.
