ARCH SHAPED LASER CATHETER

摘要

Devices, methods and systems for removing unwanted tissue from within a patient's vasculature system are provided. Specifically, a laser ablation catheter having a tip with an open, arched-shaped cross section is described. The cross section of the tip enhances the catheter's ability to ablate, separate, and/or dilate the various layers within a patient's vasculature, thereby facilitating the removal undesirable lesions and fibrous tissue within a patient's vasculature.

主权项

1. A catheter comprising:
a shaft having a proximal end and a distal end; a tapered portion coupled to the distal end; a tip coupled to the tapered portion, wherein the tip comprises an open arch-shaped cross sectional profile taken along a plane perpendicular to a longitudinal axis of the tip and/or the shaft, wherein the tip is at least partially constructed of metal, and a plurality of optical fibers having an exposed end, wherein the optical fibers are encapsulated within the shaft, the tapered portion and the tip, and wherein the exposed end of the optical fiber is exposed at the tip.
