In some embodiments, a catheter device may include a catheter including a proximal end and a distal end. The catheter device may further include a connector coupled to the proximal end of the catheter. The connector may include a base having a recess configured to receive the distal end of the catheter and may include a hinged portion configured to couple to the base to clamp the catheter within the recess.

Disclosed is a catheter device including a proximal tube having a first part of a first lumen; a distal tube having a second part of the first lumen; a second lumen connecting the proximal tube and the distal tube; wherein the connection comprise an area of discontinuity between the first part and second part; wherein the area of discontinuity comprises a support element configured to resist axial movement of the distal tube relative to the proximal tube and vice versa; and wherein the second lumen is arranged to activate or cause at least one obstruction element to restrict the flow of urine from the proximal tube to the area of discontinuity and to restrict the flow of urine from the area of discontinuity to the distal tube.

A long-lasting, wireless, biocompatible pressure sensor device is integrated within a hydrocephalus shunt, either within the shunt's reservoir/anchor or as an inline or pigtailed connector. When integrated within a typical reservoir, the device can sit within the reservoir's hollow frustum area covered by the resilient silicone dome of the reservoir. When integrated as an inline connector, the device can sit at any point on the peritoneal catheter or ventricular catheter, including between the VP shut's valve and reservoir. The pressure sensor device includes electronics that can be powered wirelessly by a reader held to a patient's scalp, and so no battery may be required. The reader can transmit an ambient, atmospheric pressure reading from outside the skull to the implanted device so that its electronics can calculate a calibrated gauge pressure internally and then relay it to a patient's smart phone.

A system including a flow control assembly. The system may include a flow regulating shunt system, for various purposes such as a use as a hydrocephalus shunt. The flow control assembly may be controlled according to selected parameters and methods. These include controlling microelectromechanical (MEMS) system to control a pressure in the flow control assembly.

A fistula treatment system comprises a guide such as a guide coil 1101 which is adapted to extend partially around a tissue tract and an implant element 1102. The implant element 1102 is activated to draw tissue surrounding the tract inwardly.

Methods and apparatus for improving cognitive function within a human. The invention utilizes an implanted device, such as an implantable signal generator or an implantable pump, to affect tissue elements within a Papez circuit of the human brain as well as tissue upstream or downstream from the Papez circuit. The implanted device delivers treatment therapy to thereby improve cognitive function by the human. A sensor may be used to detect various symptoms of the cognitive disorder. A microprocessor algorithm may then analyze the output from the sensor to regulate delivery of the stimulation and/or drug therapy.

A catheter mounting arrangement including a main housing unit configurable to be fastenable around a catheter that has been inserted into a fluid cavity within a patient. The main housing unit includes a slot that defines a longitudinal opening through which an uninserted section of tubing of the inserted catheter is passable there through. The main housing unit and inserted catheter includes an engagement arrangement so that once the uninserted section of the tubing of the inserted catheter has passed through the slot there is a fixed vertical support of the catheter within the main housing unit so that the uninserted section of tubing of the inserted catheter remains substantially upright and/or substantially free of kinks or bends.

A shunt for draining fluid including a first catheter, an electronic pump fluidly coupled to the first catheter, a manual pump fluidly coupled to the electronic pump, a second catheter fluidly coupled to the manual pump. During a drainage operation, the shunt arranged and configured such that a fluid is passively pressure-driven through the shunt, and the electronic pump is arranged to prevent blockages within the shunt by flowing a bolus of the fluid through the shunt. Additionally, the manual pump is arranged to prevent blockages within the shunt by flowing a bolus of the fluid through the shunt in the event that the electronic pump cannot produce a bolus of the fluid.

The devices and methods described herein include an implantable body lumen fluid flow modulator including an upstream flow accelerator separated by a gap from a downstream flow decelerator. The gap is a pathway to entrain additional fluid from a branch lumen(s) into the fluid stream flowing from the upstream flow accelerator to the downstream flow decelerator.
