SYSTEMS AND METHODS FOR A CEREBROSPINAL FLUID FLOW DETECTOR
Embodiments for a cerebrospinal fluid flow detector for detecting the flow of cerebrospinal fluid are disclosed. In some embodiments, the cerebrospinal fluid flow detector includes a casing with a rotatable wheel having a plurality of radially extending arms disposed therein. The rotatable wheel is in communication with a channel having a distal end in communication with an inlet port and a proximal end in communication with an outlet port such that the flow of cerebrospinal fluid through the channel causes the rotatable wheel to rotate. In some embodiments, each radially extending arm includes at least one radiopaque marker in which movement of the rotatable wheel caused by fluid flow through the channel allows an X-ray imaging apparatus to detect the difference in position of a respective radiopaque marker at multiple times caused by rotation of the rotatable wheel.
Endovascular cerebrospinal fluid shunt
An endovascular implantable shunt device for draining cerebrospinal fluid from a patient's subarachnoid space includes a shunt having opposed first and second ends, a one-way valve located at the first end of the shunt, a helical tip disposed at the second end, and a hollow passageway extending between the helical tip and one-way valve. The helical tip is constructed to penetrate a patient's sinus wall. Cerebrospinal fluid drains through the helical tip and out through the valve.
Automatic regulating system for regulation of liquid pressure in a human body
An automatic regulating system for regulation of liquid pressure includes a container, a tubing connected between the human tissue and the container, a switch unit controllable to switch between first and second states, a pressure sensor for measuring liquid pressure in the human tissue, a level sensor for detecting a liquid level in the container, and a control module controlling switching of the switch unit according to the liquid pressure and the liquid level detection. Fluid communication between the human tissue and the container is prevented in the first state but is permitted in the second state. Fluid communication between the human tissue and the pressure sensor is permitted in the first state but is prevented in the second state.
PROCESS FOR TREATING GLAUCOMA
A process for treating glaucoma whereby the treatment can be accomplished by the use of medication or by surgery, or both, in order to control or prevent the occurrence of glaucoma. The optic nerve is aligned within and between two distinct pressurized spaces and within the dural sheath, the intraocular space and the intracranial space having an intraocular pressure (IOP) and an intracranial pressure (ICP), respectively. Medicine can be administered to raise the intracranial pressure in order to reach a desirable lower translaminar pressure difference across these two pressurized spaces which are separated by the lamina cribrosa in order to treat glaucoma. An alternate closely related mode of the treatment process is the implanting of a shunt substantially between the intraocular space and the intracranial space in order to beneficially equalize pressure differentials across the intraocular space and the intracranial space.
CEREBRAL SPINAL FLUID SHUNT PLUG
A cerebral spinal fluid shunt plug includes a shunt plug housing having a recess formed therein and a shunt valve shaped and dimensioned for positioning within the recess of the shunt plug housing.
A NOVEL LOW-PROFILE VENTRICULOAMNIOTIC SHUNT FOR FETAL AQUEDUCTAL STENOSIS
The invention relates to an in-utero ventriculoamniotic shunting device that includes a shunt tube (26) composed of polymer composite and having metallic wire embedded therein, one or more anchors (30) composed of superelastic wire, e.g., thermal shape-set nitinol structures, that are mechanically attached to an exterior surface of the shunt tube (26), and a one-way passive valve (32) composed of a thin polymer membrane. The anchors (30) are effective to prevent migration and dislodgement of the shunting device following its deployment, and the valve (32) is effective to prevent the backflow of amniotic fluid (23).
Method and tools for implanted device
A method and toolset capable of remotely moving a rotor of an implanted device in a first arcuate direction and detecting a first limit of travel, moving the rotor in a second, opposite direction and detecting a second limit of travel without altering the current performance setting of the implanted device, comparing the first and second limits of travel with known values for a plurality of selectable performance settings, and indicating the current performance setting of the implanted device.
FLUID CONTAINERS AND SYSTEMS AND METHODS FOR DETECTING A FLUID LEVEL THEREIN
Fluid containers having a volume marking(s) and conductive element(s) disposed at the volume marking(s) and a common conductive element are provided. For example, the fluid container has a wall forming the volume. The conductive element(s) and the common conductive element have a portion disposed within the volume and a portion external to the volume. The container further has a RFID tag, where the conductive element(s) and the common conductive element are connected thereto via respective conductive wires. A fluid detection system having the fluid containers is also provided. The system comprises one or more containers and a patient site monitor having a RF reader that interrogates the RFID tag at a preset interval. Responsive to the signal, the tag supplies a predetermined current to the conductive element and the common conductive element and detects a voltage and generates an alert based on the same.
Cerebrospinal-Fluid Shunt Valve System
The present invention provides a cerebrospinal fluid shunt system that monitors the intracranial pressures over a portion of a monitoring cycle to calculate short intervals of drainage for every monitoring cycle necessary to produce the desired pressure correction. The system operates to significantly reduce the time during which draining occurs allowing tissue surrounding the catheter to rebound from the catheter holes returning to its normal position for a sufficient amount of time to recover its normal shape.
ONE-PASS CATHETER TUNNELER
A system for inserting a medical tube within the body using a tunneler device enables formation of a tunnel within the body and further enables concurrent insertion of the medical tube within the body as the tunnel is formed, eliminating extra steps required by current technologies for insertion of the medical tube within the body. The tunneler device provides an attachment element that captures the medical tube and further provides a handle slidably mounted along the tunneler device to aid practitioners when inserting the tunneler device into the body. The tunneler device further provides a bend angle to aid practitioners in forming the tunnel past the clavicle of the body. The tunneler device enables practitioners to place medical tubes within the body while reducing time and friction commonly associated with medical tube placement procedures.
