Apparatus and method for detecting connectivity in a channel in an endoscope undergoing reprocessing using an automatic reprocessor, the apparatus including a source of pressurized fluid which may be a gas alone or gas and liquid and a back pressure detector connected to the channel or channels of interest in the endoscope, the method including providing a source of pressurized fluid, directing the pressurized fluid to a channel in an endoscope, monitoring the time for the back pressure in the pressurized fluid to decay to a predetermined level; and determining whether the channel is connected and open or disconnected by comparing the decay time of the actual back pressure to one or more predetermined values corresponding to the specific channel or channels and model of endoscope undergoing reprocessing.

Endoscope reprocessor connectivity apparatus and method

An on board monitor for an endoscope reprocessor for monitoring the performance and order of a predetermined set of critical steps for reprocessing an endoscope. The monitor will only allow the overall system to reach the last step indicating successful completion of the process related to the critical steps representing successful reprocessing of an endoscope after the system successfully completes all of the previous critical steps and in the correct order.

On board monitor for endoscope reprocessor

An intravascular device for measuring blood pressure and flow is disclosed, which includes an elongate shaft having a pressure transducer and a flow transducer connected to its distal end. The pressure transducer may be a ferrofluid-type pressure transducer and the flow transducer may be an anemometer-type flow transducer. Measurement circuitry is also disclosed which provides a means for simultaneous measurement of both blood pressure and blood flow parameters. A sensor shield may be employed to isolate radial blood flow which is indicative of turbulent blood flow. An alternative blood flow measurement device is also disclosed which utilizes a thin metal film anemometer to measure flow in a vascular lumen.

Intravascular pressure and flow sensor

A sensor coil is located on guidewire or perfusion catheter and introduced into the body. First the sensor coil is isolated from blood flow and used to make a set of static measurements. Next the sensor coil is heated in the presence of blood flow and a set of dynamic measurements are made which reflect the blood flow past the sensor coil.
