<p>A device allowing access of a medical sensor probe to a selected location within a patient's body comprises a disposable elongated tubular sheath (2) releasably attached eg. by sutures 7 at its closed distal end (10) to the wall of a blood vessel (1) during surgery. The sheath leads out of the patient's body and provides an access path through which a sensor probe, such as an. ultrasound probe (3), can be introduced in order to allow monitoring of blood flow within the vessel. The probe can be easily removed and replaced without contamination. When monitoring is complete, the releasable attachment means, sutures 7, are operated by wire 6 and the sheath can be pulled out of the patient's body without further surgery. <IMAGE></p> |
