An intracranial prosthesis comprised of a relatively flat, ultrasound-compatible body capable of engaging a plurality of diagnostic instruments and/or intracranial delivery systems so that a practicing medical professional can monitor certain parameters of a patient or deliver therapeutic agents to the patient while using an ultrasound-monitoring device to image the patient's brain. The prosthesis is designed to allow for the continuous, uninterrupted, simultaneous monitoring of a number of parameters of a patient's brain at the patient's bedside.

A method for treatment of a brain and/or spinal cord includes inserting a flexible catheter into a cerebrospinal fluid space, the flexible catheter including two lumens adapted to allow a fluid to circulate therein in a closed loop within the flexible catheter and the flexible catheter being adapted to be connected to a device for cooling and circulating the fluid. The cerebrospinal fluid in the cerebrospinal fluid space is cooled with the flexible catheter to enable selective central nervous system cooling. The functional status of the brain and/or spinal cord is monitored, and the treatment of the brain and/or spinal cord is modified to adjust for any change in the functional status of the brain and/or spinal cord.

Verifying whether a magnetic field resistance mechanism is properly engaged in a drainage valve having an adjustable valve unit including a rotating construct and a pair of primary magnetic elements for programming the valve unit. Using a toolset, a determination is made whether the magnetic field resistance mechanism is properly engaged. An alert is generated whether the magnetic field resistance mechanism is at least one of properly engaged or not properly engaged based on: (i) a measured angular position of a detected one of the pair of primary magnetic elements relative to a direction of flow of fluid through the valve; and/or (ii) a measured distance separation between respective centers of the pair of primary magnetic elements.

A method of using an electronic toolset for locating, reading, adjusting and confirming adjustment of an implantable bodily fluid drainage system without requiring recalibration following adjustment from a current valve setting to a new valve setting using an electronic toolset including an adjustment tool having a magnetic element and an indicator tool including a sensor array. The need to remove the electronic toolset from the patient to recalibrate or zero the sensor array prior to confirming the new valve setting is eliminated. This is realized by disposing a ferromagnetic system component of the indicator tool in a magnet shield cage made of a metallic alloy to prevent magnetic fields produced by a magnetic element in the adjustment tool during the adjusting step from influencing the sensor array.

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.

Disclosed is an implantable catheter for fluid passage, including a catheter tube, a catheter tip member including one or more apertures and an open proximal end, and a cleaning unit at least partially positioned within the catheter tip member. The catheter tip member is connected at the proximal end thereof to the catheter tube, thereby fluidly coupling the catheter tube to an exterior of the catheter. The cleaning unit is configured for movement within the catheter tip member such as to mechanically prevent, mitigate, and/or remove blockage in the one or more apertures when the catheter tip member is implanted in a body cavity. The catheter tip member further includes a stopper configured to be engaged by a tip portion of a mandrel, such as to prevent the mandrel from reaching and/or damaging the cleaning unit when using the mandrel to guide the catheter tip member into the body cavity.

In one embodiment, a system for evacuating subdural hematomas includes an inlet configured to be placed in fluid communication with a subdural space, an irrigation reservoir in fluid communication with the inlet and configured to supply irrigation fluid to the inlet and the subdural space, an outlet separate from the inlet and also configured to be placed in fluid communication with the subdural space, and a pump in fluid communication with the outlet and configured to create negative pressure within the subdural space and evacuate fluid from the subdural space.

The present disclosure provides a fluidic device including (a) a first channel including a first inlet and a first outlet, (b) a second channel including a second inlet and a second outlet, wherein the second inlet of the second channel is in fluid communication with the first outlet of the first channel, and (c) a sensor positioned between the first outlet and the second inlet, wherein the sensor includes a sensor configured to deflect in response to a flow between the first channel and the second channel.

An implantable bodily fluid drainage system including a collection vessel and a mechanical volume limiting mechanism for preventing overfill of the collection chamber. The mechanical volume limiting mechanism is not susceptible to malfunction if immersed in the bodily fluid. Moreover, the volume capacity of the fluid collection chamber is adjustable in addition to the overfill prevention functionality.
