The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.

Abstract: A catheter system for pressure wave and inertial impulse generation for intravascular lesion disruption at a treatment site includes a catheter including an elongate shaft and balloon coupled to the elongate shaft. The catheter system includes a light guide disposed along the elongate shaft and at least partially within the balloon, where the light guide is in optical communication with a light source and a balloon fluid. The catheter can include a first focusing element located at a distal portion of the light guide and in optical communication with the light source. The first focusing element can direct light from within the light guide to a first location at a first distance away from the distal portion of the light guide to initiate plasma formation in the balloon fluid away from the distal portion and to cause rapid bubble formation, thereby imparting pressure waves at the treatment site.

Abstract: A catheter system (100) for placement within a treatment site (106) at a vessel wall (208A) or a heart valve includes an energy source (124), a balloon (104), an energy guide (122A), and a tissue identification system (142). The energy source (124) generates energy. The balloon (104) is positionable substantially adjacent to the treatment site (106). The balloon (104) has a balloon wall (130) that defines a balloon interior (146). The balloon (104) is configured to retain a balloon fluid (132) within the balloon interior (146). The energy guide (122A) is configured to receive energy from the energy source (124) and guide the energy into the balloon interior (146) so that plasma is formed in the balloon fluid (132) within the balloon interior (146). The tissue identification system (142) is configured to spectroscopically analyze tissue within the treatment site (106). A method for treating a treatment site (106) within or adjacent to a vessel wall (208A) or a heart valve can utilize any of the catheter systems (100) described herein.

Abstract: A catheter system includes a catheter having an elongate shaft, a balloon and a light guide. The balloon expands from a collapsed configuration to a first expanded configuration. The light guide is disposed along the elongate shaft and is in optical communication with a light source and a balloon fluid. A first portion of the light guide extends into a recess defined by the elongate shaft. A protection structure is disposed within the recess and is in contact with the first portion of the light guide. The light source provides pulses of light to the balloon fluid, thereby initiating plasma formation and rapid bubble formation within the balloon, thereby imparting pressure waves upon a vascular lesion. The protection structure can provide structural protection from the pressure waves to the first portion of the light guide.

Abstract: Embodiments herein relate to systems and methods for intravascular lesion disruption. In an embodiment, a catheter system for imparting pressure to induce fractures upon a vascular lesion within or adjacent a blood vessel wall is included. The system includes a catheter configured to advance to a vascular lesion, the catheter including an elongate shaft that defines at least a first orifice for fluid flow; a balloon, coupled to the elongate shaft, that surrounds the first orifice where the balloon can expand from a collapsed configuration suitable for advancing the catheter through a patient's vasculature to a first expanded configuration suitable for anchoring the catheter in position relative to a treatment site; and a propulsion system configured to propel a fluid from the first orifice toward the balloon wall to create an inertial impulse in a vessel wall to transfer momentum to the vascular lesion. Other embodiments are also included herein.
