NOVEL ENHANCED PTNA RAPID EXCHANGE TYPE OF CATHETER SYSTEM
First Claim
1. An intracerebral rapid exchange balloon catheter system effective for accessing and dilating blood vessels within the brain, comprising, in combination:
- a catheter comprising a RX port with length of between at least about 25 cm and about 50 cm for providing catheter support within and above the carotid siphon and distal vertebral arteries;
a conformable, semi-compliant balloon, the balloon manipulable to gain forward progress through intracranial vessels substantially narrowed by plaque in combination with at least a guidewire; and
a tip disposed at a distal end of the catheter.

Abstract
Novel systems enable PTNA rapid exchange (RX) types of systems for ICAD, support balloon test occlusion, treatment of vasospasm after sub-arachnoid hemorrhage (SAH) and facilitate aneurysm neck remodeling during coiling embolization. The systems disclosed include an embodiment having a catheter comprising a RX port for providing catheter support within and above the carotid siphon and distal vertebral arteries, a conformable, semi-compliant balloon manipulable to gain forward progress through intracranial vessels substantially narrowed by plaque in combination with at least a guidewire, and a tip disposed at a distal end of the catheter.
