A medical device suitable for introducing a medical instrument into a patient includes an outer cannula and at least one arm connected to the cannula toward a proximal portion of the at least one arm. The at least one arm is deployable between a closed position and an open position. An inner member is telescopically received in the outer cannula to hold each arm in the closed position. The inner member is deployable to disengage from the arm after the device is inserted into a patient, thereby freeing the arm to be deployed to the open position where it helps hold the outer cannula in the patient. The inner member includes an inner cannula and/or a trocar.

An optical measurement device calibration tool includes an optical probe suitable for calibrating various optical imaging devices, for example, low coherence reflectometers and optical coherence tomography devices. In a preferred embodiment the calibration tool comprises a container containing a calibration substance with stable optical scattering and absorption properties. The calibration substance includes a gel, paste or grease substance and is covered a protective seal, which is at least partially transparent providing optical contact between the optical probe and the calibration substance. The protective seal is covered with a viscous complementary material. Another protective seal made at least partially removable is placed above the viscous complementary material and may serve as a cover for the container. The calibration tool maintains the advantages of calibration tools using liquids and solid states as calibration substance and is more cost-effective and more convenient for calibrating optical measuring devices such as in medical applications.

An environmentally friendly decontaminant solution, which may be disposed of after use without posing significant environmental hazards, is formulated without molybdenum-based corrosion inhibitors and preferably is free of all heavy metals. A zeolite-based buffering system optionally replaces phosphate buffers for maintaining the pH of the decontaminant solution at an appropriate pH for effective antimicrobial decontamination. Molybdenum-free decontaminant solutions containing peracetic acid retain their peracetic acid levels, and thus their antimicrobial effectiveness, for longer periods than comparable solutions formulated with a molybdate corrosion inhibitor.
