Catheter assembly for intracranial treatment
First Claim
1. A catheter assembly for intracranial treatment of a tissue region of the brain of a patient comprising:
- an outer catheter having a proximal end, an opening at the proximal end, at least one element and at least one aperture, the outer catheter defining a lumen in communication with respect to the opening and the at least one aperture, the element being adapted to monitor brain activity within the tissue region, to electronically stimulate the tissue region, or to provide information on a precise position of the element when the element is located entirely within the brain and being mounted proximal to a distal end of the outer catheter upon an exterior surface of a distal portion of the outer catheter, the proximal end including an attachment member formed thereat and adapted to be directly attached to the patient'"'"'s skull after the outer catheter is placed in the tissue region; and
an inner catheter sized to be received within the lumen and having a passageway and at least one port in communication with respect to the passageway.

Abstract
A catheter assembly for intracranial treatment of a patient is provided having both outer and inner catheters. The outer catheter has at least one element and defines a lumen in communication with at least one aperture and an opening. The inner catheter is sized to be received within the lumen and includes a passageway in communication with at least one port. The element can be in the form of a contact or sensor. The outer catheter can include an inflatable balloon distal to an element. The balloon is adapted to seal upon inflation the tract created by the outer catheter when inserted into the brain. The outer catheter may have a flexible channel extending outward from the body of the catheter that permits the inner catheter to be inserted into the body through the channel. The inner catheter is preferably configured for removable engagement to a tapered fitting on the outer catheter.
