摘要： A medical device includes a flexible member having a hollow cavity extending between a proximal end and a distal end, an optical fiber extending through the hollow cavity, and a potting material to secure/pot the optical fiber to the distal end to inhibit damage of the distal end. The potting material can be an adhesive, such as a UV curable adhesive or dual-cure adhesive. The medical device can be stripped or a buffered optical fiber, and can include a spacer, wherein the optical fiber can be fused to the spacer, and potted in the distal end. The medical device can have a rebuffer heat shrink tube surrounding the area of the optical fiber on a guidewire, and can have distal optics at the distal end that include at least a spacer, a lens and a reflector. The medical device can be a disposable catheter, and an MMOCT catheter.

摘要： One or more devices, systems, methods and storage mediums for performing medical procedure (e.g., needle guidance, ablation, biopsy, etc.) planning and/or performance, and/or for performing guidance of multiple probes or multiple needles, are provided. Examples of applications for such devices, systems, methods and storage mediums include imaging, evaluating and diagnosing biological objects, such as, but not limited to, lesions and tumors, and such devices, systems, methods and storage mediums may be used for radiotherapy applications (e.g., to determine whether to place seed(s) for radiotherapy). Even in instances where communication between a medical tool or needle guidance device and a system is wireless or wired, preferably guidance information is still gathered and transmitted, especially in instances where wireless or wired communication signals are intermittent or interrupted.
