The disclosure provides a system and method for a programmable medical wire that can be preprogrammed, and controlled and reshaped upon command. The system can include a power supply, a controller, and a multilayered wire assembly. The wire assembly includes a core conductor, actuator conductors coupled to the core conductor, selective conductors formed adjacent the core conductor and the actuator conductors, and a protective biocompatible shield around the layers. The selective conductors can be energized to activate the actuator conductors and cause the actuator conductors to bend or twist in a preprogrammed manner. By selectively controlling the direction of movement of the actuator conductors, the wire assembly can be remotely guided through body passageways to the target. Auxiliary equipment such as sensors, micro cameras, detectors, cutters, and other equipment can also be coupled to the wire assembly, and controlled and communicated with through one or more of the selective conductors.

The present disclosure provides a system and method for using widely available ultrasound imaging to overcome the limitations of imaging guidewires and other small objects that may be subwavelength in size relative to an ultrasound wavelength. The system and method can reduce the use of X-rays and exposure to the dangerous effects of radiation and avoids the expense of MRI technology. The subwavelength object, such as a guidewire, can be detected using several methods and associated systems described herein, including the object changing positions at a frequency that creates a brighter ultrasound image of the object as the object progresses across a scanned region of the ultrasound detector. In some embodiments, the movement of the small object causes a different speckle signature than the object itself would otherwise generate. Analysis of changes in speckle patterns due to progressive movement of an object can yield a detectable object.

A first embodiment of the implantable real-time oximeter of the present invention is attached around a blood vessel near the site of a likely stroke to monitor large and medium size cerebral arteries. Another embodiment of the implantable real-time oximeter can be passed within cerebral blood vessels to monitor the oxygenation status of the surrounding cerebral tissues. When used within cerebral blood vessels, the emitter and detector are coplanar and contained in a small area, for example,-&#x3bc;m.

There is provided an implantable pressure monitor having a fluid sack in contact with a body part of a patient where the fluid sack is retained to the body part by a pressure monitor housing that may have various attachment means. The fluid sack is filled with a liquid such as silicone oil. The pressure monitor housing has an opening that provides access to a fistula with a fluid valve that terminates through the fluid sack. A fiber optic pressure sensor is in contact with the liquid in the fluid sack by way of the fistula and fluid valve. In some embodiments of the present invention, an electronics module is incorporated with the implantable pressure monitor to provide telemetry, power, and the like.

A deep brain magnetic stimulator is disclosed that is placed within a vessel of the body to provide targeted location specific application of a magnetic field within the brain. The deep brain magnetic stimulator has a stimulation coil affixed to an expandable device core where the device core has a lumen to allow the passage of blood. A source of electrical energy is provided as well as related control circuitry to govern the activation of the stimulation coil and also govern such parameters as magnetic field strength, duration, waveform, and the like.
