Abstract
An intraosseus shunt can comprise a shunt body and a valve. The shunt body can be configured for insertion into bone and can have a fluid inlet, a fluid outlet, and a flow passage extending within the shunt body between the fluid inlet and the fluid outlet. The flow passage, the fluid inlet, and the fluid outlet can be configured for cerebrospinal fluid flow therethrough to cancellous bone. The valve can be attached to the shunt body and configured to control flow through the flow passage. A method of shunting biological fluid away from a hyper-pressurized biological cavity to a bone can comprise (i) creating a passage through cortical bone to provide access to cancellous bone, and (ii) positioning the shunt into the passage. The valve can control communication between the biological cavity and the cancellous bone.
Claims20
An intraosseus shunt comprising:
- a shunt body configured for insertion into bone and having a fluid inlet, a fluid outlet, and a flow passage extending within the shunt body between the fluid inlet and the fluid outlet, wherein the flow passage, the fluid inlet, and the fluid outlet are configured for cerebrospinal fluid flow therethrough to cancellous bone;
- wherein the shunt body comprises a first portion configured to extend through a pedicle of a vertebra, and second portion configured to extend into a subarachnoid space in a spinal canal, the first portion and the second portion coupled together.
A method of shunting cerebrospinal fluid from a cerebrospinal fluid cavity to a vertebra, the method comprising:
- creating a passage through cortical bone, and into cancellous bone, of the vertebra;
- and
- positioning a shunt such that the cerebrospinal fluid cavity is in communication with the cancellous bone.
A method of shunting biological fluid from a pressurized biological cavity to a bone, the method comprising:
- positioning a first end of a tube in a vertebral body;
- positioning a second end of the tube in a subarachnoid space;
- wherein the tube has a length of less than 100 mm between the first end and the second end.
