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.

A comfortable device for treating sleep apnea incorporates a mask, a flexible hose and a chamber for collecting expired air containing CO. A sensor detects apnea and a control system automatically adjusts the amount of rebreathed COto minimize apnea and also minimize arousal.

An electrode array supports multiple electrodes and energizes them so that adjacent electrodes do not have the same polarity. In one embodiment, the electrodes are held about a circumference outside and surrounding a tumor and opposed electrodes are energized in a round robin fashion to promote current flow through the center of the tumor from a variety of angles.

The device to monitor distance between people measures a pre-defined distance between a first person and other persons, and alerts the user when the pre-defined distance has been breached or violated for more than a pre-determined time. Intended to protect a first human from the deleterious effects of radiation (nuclear) associated with a second human, but useful in other circumstances, the device is designed to detect the presence of a first person within a protective radius of one to two meters of a second person by pairing the combination of one heat sensor with one distance sensor. In the event the first person is within that radius for the predetermined time, the device will alert the user of that circumstance. Alert feedback mechanisms can include an acoustic audible signal, a visible signal, a vibratory signal, or phone notification.

A method of resection of an organ employs a handheld microwave waveguide that receives a microwave signal and applies a substantially planar microwave beam into the organ for coagulation of a strip of tissue in an organ providing a barrier against blood loss during resection operations.

Efficient ablation with multiple electrodes is obtained by rapidly switching electric power to the electrodes. In this way, shielding effects caused by the field around each electrode which would otherwise create cool spots, are avoided. Complex inter-electrode current flows are also avoided.

An antenna for microwave tumor ablation provides coaxial antenna conductors surrounded by an insulated sleeve of length and size promoting destructive interference of axial microwave energy passing inside and outside of the sleeve to limit the tail of SAR power toward the skin.

An apparatus and method for detecting, monitoring, measuring and recording the motion of a patient's spine is disclosed. The apparatus includes a vertical member attached to a belt that fits around the patient's waist. A first sensor for detecting and monitoring flexion and extension of the patient's spine in the midsagittal plane is mounted to the lower end of the vertical member. A second sensor for detecting and monitoring lateral bending and movement of the patient's spine in the frontal plane is mounted to the upper end of the vertical member.
