MICROCATHETER SYSTEM
First Claim
1. A system for use in a vascular procedure, which comprises:
- a guidewire dimensioned to remotely access a neurovascular space;
a microcatheter including;
a catheter member defining a longitudinal axis and having a longitudinal length and with proximal and distal ends; and
a catheter hub connected to the proximal end of the catheter member, the catheter hub dimensioned and adapted to be selectively released from the catheter member;
an interventional treatment element for passage within the catheter member of the microcatheter, the interventional treatment element adapted to perform treatment on the lesion within the vasculature.an outer guide positionable over the catheter member of the microcatheter upon removal of the catheter hub, the outer guide advanceable over the catheter member to a location proximate the lesion.

Abstract
A system for use in a vascular procedure includes a guidewire dimensioned to remotely access a neurovascular space, a microcatheter for positioning over the guidewire, an interventional treatment element for passage within the catheter member of the microcatheter, and an outer guide positionable over the catheter member of the microcatheter upon removal of the catheter hub. The microcatheter includes an elongated catheter member and a catheter hub. The catheter member defines a longitudinal axis and has a longitudinal length and with proximal and distal ends. The catheter hub is connected to the proximal end of the catheter member and is dimensioned and adapted to be selectively released from the catheter member. The outer guide is advanceable over the catheter member of the microcatheter after the catheter hub is released from the catheter member to a location proximate the lesion. The interventional treatment element is adapted to perform treatment on the lesion within the vasculature

14. A method for performing a neurovascular procedure, comprising:
-
accessing a treatment site within a neurovascular space with a guidewire; advancing a microcatheter over the guidewire to traverse remote locations in the neurovasculature to access the treatment site and penetrate a lesion located at the treatment site without the assistance of an independent outer guide support positioned about the microcatheter; removing the guidewire from the microcatheter; introducing an interventional treatment element through the microcatheter to a location adjacent the lesion within the neurovasculature; treating the lesion with the interventional treatment element; removing a catheter hub member from the microcatheter leaving an catheter member of the microcatheter within the neurovasculature; positioning an outer guide over the catheter member of the microcatheter and advancing the outer guide to a location proximate the treatment site; and withdrawing the microcatheter through the outer guide. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
