Abstract

Claims (20)

1 . An implantable system for measuring intracranial pressure (ICP) in a brain, the system comprising:

an implant comprising:

a body having a proximal side and a distal side, wherein the distal side is configured to be adjacent an outer portion of a skull,

a pressure conduction catheter coupled with the distal side of the body,

at least one sensor configured to obtain data, and

a processor, configured to receive said obtained data and determine an ICP based at least in part on the obtained data; and

a retaining mechanism comprising:

a distal surface configured to be adjacent at least a portion of the skull,

a proximal surface opposite and spaced apart from the distal surface, and

an inner surface defining a central lumen that extends between the distal surface and the proximal surface of the retaining mechanism and having an inner geometry, wherein the inner geometry is configured to receive the implant body and at least a portion of the pressure conduction catheter therethrough, and wherein the proximal surface of the retaining mechanism is positioned at or below the outer portion of the skull.

2 . The system of claim 1 , wherein the implant further comprises:

the pressure conduction catheter configured to extend into the brain and including a plurality of ports; and

a diaphragm configured to deform in response to changes in ICP at the plurality of ports.

3 . The system of claim 1 , the implant further comprising at least one standoff coupled with and extending distally away from the distal side of the body and spaced radially outward from a central axis of the body.

4 . The system of claim 1 , wherein the inner surface of the retaining mechanism further comprises at least one retaining protrusion configured to engage the implant.

5 . The system of claim 4 , wherein the at least one retaining protrusion comprises at least one engagement structure that extends radially inward toward a central axis of the retaining mechanism.

6 . The system of claim 1 , wherein the inner surface of the retaining mechanism further comprises threads configured to engage the implant.

7 . The system of claim 1 , wherein the retaining mechanism further comprises an outer surface comprising at least one tissue engaging structure.

8 . The system of claim 7 , wherein the at least one tissue engaging structure comprises one or more of i) adhesive, ii) a locking pin, or iii) one or more screws extending from the distal surface of the retaining mechanism configured to engage bone.

9 . The system of claim 1 , wherein the retaining mechanism comprises a gasket.
