MATERIAL REMOVAL CATHETER HAVING AN EXPANDABLE DISTAL END

摘要

Catheters for ablation and removal of occlusions from blood vessels are provided. Laser cutting systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Catheters include expandable distal ends to facilitate, in some cases, relatively high bodily material removal rates compared to other devices.

主权项

1. A catheter system for cutting bodily material of a subject, the catheter system comprising:
a catheter having a wall, the wall comprising a distal end carrying a cutting instrument adapted to cut bodily material of the subject, the distal end being reconfigurable from a collapsed configuration to an expanded configuration, the wall further comprising an orifice disposed at the distal end, the orifice being in fluid communication with a lumen extending proximally from the distal end, the lumen being adapted to receive cut bodily material; and a release mechanism coupled to the catheter, the release mechanism being actuatable to reconfigure the distal end from the collapsed configuration to the expanded configuration.
