Abstract

Ultra-small optical probes comprising a single-mode optical fiber and a lens which has substantially the same diameter as the optical fiber. In one embodiment a coreless fiber (8) is fusion spliced to the end of a single mode optical fiber (1) and a multimode optical fiber serving as a lens is fusion spliced to the coreless fiber (8). The multimode fiber acts as a graded index (GRIN) lens. The optical fiber and lens are positioned in a probe housing which is in the form of an insertional medical device such as a guidewire. Connector elements are provided to facilitate the attachment of the probe to an optical system and the quick disconnection of the probe from the optical system. The probe is used to obtain optical measurements in situ in the body of an organism and can be used to guide interventional procedures by a surgeon.
