In a method of manufacturing an ultrasonic transducer array a plurality of discrete transducer elements are formed on an initially flat flexible substrate together with electrically conductive tracks, through which the transducer elements will be energised in use, the flexible substrate with the discrete transducer elements and conductive tracks mounted thereon then being formed into a cylinder and mounted on the end of a catheter tube, the substrate being radially outwardly of the transducer elements so that it is in a position to act also as an acoustic matching layer between the material of the transducer elements and the human tissues or blood when in use.

Ultrasonic transducer array and method of manufacturing the same

An ultrasound catheter suitable for insertion in the body lumens of a patient during medical procedures is provided. An ultrasound transducer may be provided at the distal tip of the catheter. An inflatable balloon may be provided at the distal end of the catheter on the proximal side of the ultrasound transducer. The catheter may have lumens for inflation fluid, electrical wires, and a guide wire. A sheath that runs through the balloon may be used to isolate the electrical wires and guide wire from inflation fluid in the interior of the balloon.

Ultrasonic imaging devices and methods of fabrication

A catheter is provided that has both an ultrasonic transducer array (,) and a inflatable balloon (,) mounted at or near its distal end. A sheath catheter having a transducer array and associated multiplexer (,) arrangement located substantially coaxially within it. Furthermore, a guidewire (,) catheter having an ultrasonic transducer array mounted on it distal end.

Ultrasonic transducer arrangement and catheter

An infrared detector comprises an array of detector elements (2) of the type having a layer of pyroelectric material (4)sandwiched between upper and lower electrodes (6,8) and separated along each edge by separations (16). The electrical sheet resistance of the upper electrode array (6) is reduced by forming gold rims (24) on the edges of the electrodes (6) around the periphery of each separation (16).
