Abstract
A method for delivering fluid to the brain of a subject using an intraparenchymal catheter, the method comprising the step of inserting the catheter into the brain using a posterior to anterior approach and methods of treating neurodegenerative disorders using this delivery method, as well as methods for delivering fluid to an elongate structure of the brain using an intraparenchymal catheter, the method comprising the step of inserting a catheter into the brain along an insertion axis that is substantially aligned with a long axis of the elongate structure.
Claims15
A method for delivering a fluid to a brain of a subject, the method comprising delivering the fluid to the brain by inserting at least one intraparenchymal catheter into a target volume of the brain using a posterior to anterior approach along an insertion axis that is substantially aligned with a long axis of the target volume,
- wherein the target volume is at least one of the putamen, globus pallidus and the head of the caudate nucleus, and
- the catheter is inserted along a trajectory through an occipitoparietal region, the trajectory substantially parallel to an anterior commissure-posterior commissure plane.
A method for treating a neurodegenerative disorder, the method comprising delivering a fluid to a brain of a subject by inserting at least one intraparenchymal catheter into a target volume of the brain using a posterior to anterior approach along an insertion axis that is substantially aligned with a long axis of the target volume,
- wherein the target volume is at least one of the putamen, globus pallidus and the head of the caudate nucleus, and
- the catheter is inserted along a trajectory through an occiptoparietal region, the trajectory substantially parallel to an anterior commissure-posterior commissure plane.
A method for delivering a fluid to an elongate structure of a brain of a subject, the method comprising delivering the fluid to the elongate structure by inserting at least one intraparenchymal catheter having a step into the brain using a posterior to anterior approach along an insertion axis that is substantially aligned with a long axis of the elongate structure,
- wherein the step is located within the elongate structure,
- the elongate structure is at least one of the putamen, globus pallidus and the head of the caudate nucleus, and
- the catheter is inserted along a trajectory through an occipitoparietal region, the trajectory substantially parallel to an anterior commissure-posterior commissure plane.
