Optical probe accessory device for use in in vivo diagnostic procedures

Abstract

The present invention recognizes that optical probes function both as medical access devices and as instruments which collect complex optical data. The invention provides an optical probe accessory device which can access luminal spaces within the body of a patient without sacrificing the quality of optical data obtained. The accessory device further comprises either, singly, or in combination, selectable features or options which optimize light transmission, maximize patient comfort, and provide single-use capabilities.

AI Technical Summary

Benefits of technology

"The invention provides an optical probe accessory device that can access bodily spaces without sacrificing the quality of optical data collected by the probe. The accessory device can be tailored to the shape of the body space being accessed and is either a single-use or disposable device. The accessory device includes optical elements that enhance light transmission and minimize the impact of bodily fluids on the optical data collected by the probe. The accessory device can be used with a variety of optical probes and can be programmed to collect specific information about the tissue being analyzed. The invention also provides a system that includes a processor and an electrical element reader to control the actuation of the optical probe."

Problems solved by technology

However, the development of optical probes for clinical use has been hampered due to the difficulty of miniaturizing the optical elements necessary for the collection of optical data.

Additional constraints arise because an optical probe, like any medical access device, must be decontaminated and sterilized prior to reuse.

The delicate construction of light directing and focussing elements within the optical probe generally make it difficult, if not impossible, to sterilize the probe.
