A device is described which can measure changes in cerebral spinal fluid (CSF) pressure as a function of body tilt, with an added feature of delivering particular vibrations to a body. By measuring changes in CSF pressure with tilt, one can determine, among other things, a body's ability to regulate CSF pressure. In addition, when coupled with the delivery of therapeutic vibration to a body, an improvement in CSF pressure regulation and patency can be established. The device may include at least two motors in a housing with unbalanced masses coupled to their axles, such that vibration of the masses causes the two motors and housing to vibrate at a beat frequency 80. The motors and housing may be coupled to the body via a platform which places the motors and housings at or near a resonant structure in the body, creating a coupled oscillation between the platform and the body. The vibration may be based on the input signal, such that the system applies the vibration based on the input signal to the user, wherein the signal may be an audio or video signal. The system may be configured to measure and manipulate the flow of cerebral spinal fluid.

A system and method for monitoring the blood pressure of a patient that allows for a device sensor to be recalibrated according to atmospheric pressure without removing the device sensor from inside the patient. This permits quickly monitoring the blood pressure of a patient if a re-zero is needed. The invention has a blood pressure monitor (BPM) that obtains an atmospheric pressure observation. The atmospheric pressure observation is adjusted and stored to memory as a zero value. The zero value is retrieved to recalibrate the system and method if a device sensor has been disconnected from and reconnected to the same or a different BPM, the patient has been moved such that the surroundings have been altered to make it necessary to recalibrate according to atmospheric pressure, and/or the device sensor has been connected to a different patient care monitor.

Embodiments of the present disclosure provide an implantable device for monitoring properties of cerebrospinal fluid of a patient. In one embodiment, the device may include a housing, a processor, a support member, one or more sensors, and a data storage. The sensors may be in communication with the processor and configured to detect one or more properties of cerebrospinal fluid. The device may be configured for transmitting the data and receiving instructions by an operator for the delivery of a therapeutic agent or imaging agent from a reservoir disposed within the housing in operable communication with a pump.

A ventricular shunt assembly, used in conjunction with a hyperbaric environment (e.g., having a pressure of about 250 to about 350 mm H.sub.2O above atmospheric pressure) can be used to correct a patient's intraparenchymal venous pressure from a sub-normally low value to a normal value. The shunt may comprise a valve, e.g., and adjustable valve, disposed between the ventricular catheter and the distal catheter. Optionally, the shunt comprises a reservoir on the ventricular side of the valve.

Body fluid management systems and associated methods include in-line measurement and/or detection of analytes, contaminants, and/or physical characteristics for the diagnosis or detection of disease, infection, or toxicity.

A patient monitoring and/or treatment system and method is disclosed. The system includes a wearable device configured to be wearable on an external portion of a patient. The wearable device configured to monitor and/or treat a biological feature of the patient, the wearable device including: one or more ultrasonic transmitters that provide ultrasonic energy to a monitoring site and/or a treatment site of the patient; one or more ultrasonic receivers that receive reflected ultrasonic energy from the monitoring site and/or the treatment site; and a controller that controls the one or more ultrasonic transmitter and the one or more ultrasonic receivers and determines an attribute of the biological feature based on the ultrasonic energy that is provided and the ultrasonic energy that is received.

A ventricular shunt device, such as a ventriculoperitoneal (“VP”) shunt, comprising an electromagnetic flow meter attachment, in aspects attachable to pre-existing peritoneal catheters systems, providing for the capability for physicians to obtain information about the status of the VP shunt and its functionality. Due to the high failure rate of current shunt catheters and the associated dangers with shunt failure, the need for real-time monitoring is ever present. A Halbach cylinder or other electromagnetic system or array is implemented to generate a magnetic field to observe flow rates through the peritoneal catheter to serve certain functions, as well as associated applications and verification of the device in computational and experimental settings.

A device for the direct detection of pressure variations of a fluid within a body cavity comprises a pressure transducer and a cannula having a distal end which either forms or is fluidically coupled with hollow insertion means suitable to be inserted into the body cavity. The cannula and the hollow insertion means form a volume which contains an air column which can be compressed or decompressed by a pressure variation of the fluid inside the body cavity, the pressure variation of the air column being suitable to cause mechanical deformation of the sensing surface.

A multi-wavelength surgical system is provided using an endoscope sensitive in the short-wave infrared region which allows exploration of different areas of the skull base for CSF leaks. The device includes an LED box with multiple wavelengths including allowing excitation of ICG with 785-808 nm, enhancing the water absorption from 1200-1550 nm and above 1800 nm and incorporating white light to allow for surgical navigation. Because CSF is 99% water having a large absorption in the SWIR band around 1200-1550 nm and above 1800 nm, the system and method should be an effective means of diagnosis without the need for intrathecal fluorescein.
