Methods for deploying and removing an endovascular cerebrospinal fluid (CSF) shunt device in a patient's spinal subarachnoid space or third ventricle are disclosed herein. The disclosed methods can be used to treat elevated CSF pressure (e.g., acquired communicating hydrocephalus, pseudotumor cerebri), normal pressure hydrocephalus, or as a temporary measure to drain CSF and/or blood from the subarachnoid space instead of inserting an external ventricular drain in the patient.

A surgical device for cerebral herniation including a structure adapted to cover the skullcap, the structure including a first portion to provide the structure with its shape a second portion to be in contact with the cerebral parenchyma, and a plurality of tubular canals forming a lattice that subdivides the surgical device in areas corresponding to respective areas of the cerebral surface, a plurality of sensors attached to the second portion of the structure and in contact with the cerebral parenchyma, the sensors monitoring one or more parameters of the brain, an outflow system including at least one drainage catheter and a connection to an aspiration system, the outflow system positioned along the perimeter of the structure to convey waste liquids or blood outside, and the plurality of tubular canals include a plurality of administration canals, the tubular canals including an inlet extremity and an outlet extremity.

Implantable physiological shunt systems and related fluid flow control devices and accessories for use therewith. Devices, systems and methods relating to implantable medical fluid flow control devices, rotors and magnets with increased resistance to inadvertent setting changes. Devices, systems and methods relating implantable medical fluid flow control devices, rotors and magnets which provide improved magnetic coupling to fluid flow control device accessories such as adjustment tools.

A system includes a flow regulating system. The flow regulating system may assist in ensuring a selected pressure within an inlet volume. A flow regulator may be included in a shunt assembly (10).

The present disclosure relates to a shunt catheter assembly for draining cerebrospinal fluid (CSF) into a venous system of a lower spinal region. The shunt catheter assembly includes a sheath having an interior volume, a catheter disposed in the interior volume of the sheath and movable relative to the sheath, a first flange coupled to the catheter and disposed between the catheter and the sheath, and a second flange proximally located relative to the first flange and disposed between the catheter and the sheath. The first and second flanges are expandable between a compressed configuration when the first and second flanges are disposed in the interior volume of the sheath, and an expanded configuration when the first and second flanges are externally disposed relative to the sheath. The first flange is separably deliverable relative to the second flange.

Disclosed is a system including a flow regulating system. The flow regulating system may assist in ensuring a selected pressure within an inlet volume. The flow regulator may be included in a shunt assembly.

A valve assembly configured to maintain fluid flow therethrough at a constant flow rate. The valve assembly including a flexible flow control member defining an inner fluid chamber within the flexible flow control member and an inlet opening to the inner fluid chamber. An outer fluid chamber is defined between the flexible flow control member and an inner surface of a valve housing. The flexible flow control member is configured to flex inward and shrink the inner fluid chamber in response to a pressure decrease in the inner fluid chamber relative to the outer fluid chamber resulting from an increase in an inlet flow rate to maintain an outlet flow rate from the valve assembly at the constant flow rate.

The invention relates to methods and apparatus for unclogging implantable shunts, pored catheters, and other medically implantable lumen with openings for infiltration of bodily fluids and the like.

A method for removing particles from a bodily fluid in a patient with a filtering device, the filtering device being implantable in the patient's body and the method comprising the steps: pass bodily fluid of the patient through a tube forming a main fluid, filtering the bodily fluid passing through said main fluid passageway with a filter connected to the tube, collecting particles in the bodily fluid to be removed passing through the tube, and cleaning the filter with a filter cleaning device by removing particles collected by the filter out of the fluid passageway.

Systems and methods for implanting an endovascular shunt in a patient is disclosed. The system having an expandable anchor configured for being deployed in a dural venous sinus of a patient at a location distal to a curved portion of a wall of an inferior petrosal sinus (IPS) of the patient; an elongate guide member coupled to, and extending proximally from, the anchor; a shunt delivery catheter having a first lumen configured to receive the guide member, and a second lumen extending between respective proximal and distal openings in the shunt delivery catheter, the shunt delivery catheter further having a penetrating element coupled to a distal end of the catheter; and the system further having a guard at least partially disposed over, and movable relative to, the penetrating element.
