Method and apparatus for fluid delivery
First Claim
1. A method for delivering fluid to a brain of a subject, the method comprising the steps of:
- making a first incision in the subject in order to implant one or more catheters in the brain of the subject at a first location;
making a second incision in the subject at a second location different from the first location;
subcutaneously implanting a first part of a modular fluid delivery apparatus in the subject, the first part of the modular fluid delivery apparatus comprising a first length of tubing having a first end and a second end, the first end having a first fluid connector portion attached thereto and the second end being connected to the one or more catheters;
closing the first and second incisions such that the first part of the modular fluid delivery apparatus and the one or more catheters are entirely subcutaneously implanted within the subject; and
prior to the step of closing the second incision, accessing the one or more implanted catheters through the second incision by;
(i) providing a second part of the modular fluid delivery apparatus, the second part comprising a second length of tubing having a third end comprising a second fluid connector portion;
(ii) connecting the first fluid connector portion to the second fluid connector portion; and
(iii) delivering the fluid to a tissue of the brain by pumping the fluid to the one or more implanted catheters through the first and second parts of the modular fluid delivery apparatus.

Abstract
A method for delivering fluid to a brain of a subject is disclosed. This method includes the steps of: making one or more incisions in a subject; implanting one or more catheters in the brain of the subject; subcutaneously implanting a first part of a modular fluid delivery apparatus in the subject, the first part of the modular fluid delivery apparatus comprising a first length of tubing having a first end and a second end, the first end having a first fluid connector portion attached thereto and the second end being connected to the one or more catheters; and closing the one or more incisions such that the first part of the modular fluid delivery apparatus and the one or more catheters are entirely subcutaneously implanted within the subject.

8. A method for implanting an apparatus for delivering fluid to a brain of a subject, the method comprising the steps of:
-
making a first incision in a scalp of the subject at a first location in order to insert one or more catheters into the brain of the subject, each of the one or more catheters being connected by a length of tubing to a first fluid connector portion; making a second incision in the subject at a second location different from the first location; and closing the first and second incisions to thereby entirely subcutaneously bury the one or more catheters, the first fluid connector portion, and the length of tubing within the subject, wherein, after the second incision has been surgically closed, the first fluid connector portion is configured to only be accessed through a subsequent surgical procedure that includes a step of making a further incision in the subject to uncover the first fluid connector portion, the further incision configured to allow connection of a second fluid connector portion to the first fluid connector portion. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
