摘要:
A thermal sensing system includes a one-piece clip formed of a thermally conductive material. The clip includes a flat, substantially enclosed portion with tabs extending upward from it for connecting the clip to a printed circuit board. The clip also includes a contact portion that is configured to contact a thermally emitting object along a substantial portion of its surface. The thermal sensing system also includes a thermistor. The thermistor may be mounted to the printed circuit board or directly mounted to the clip. Heat is transferred from the thermal object to the thermistor via the clip. This system may be used in various arrangements in which temperature of an object is monitored or maintained within a given range. For example, the system may be used with a rechargeable mouse to monitor the temperature of the replaceable battery during charging and discontinue charging should the temperature reach a predetermined limit.

The pressure monitoring guidewire comprises an elongated tube made of one piece of elastic Nickel Titanium alloy. The distal end portion of the tube has transverse openings formed through the tube wall for the entry of pressure waves into a lumen. The distal end portion of the tube which encompasses the openings, is malleable. The pressure monitoring guidewire can be formed by thermally treating the distal end portion of a guidewire formed of an elongated tube of one piece of elastic Nickel Titanium alloy having a distal end portion with transverse openings.

The appliance comprises a core wire on which is mounted a coil of radioactive material. A first proximal radiopaque coil configuration and a second distal radiopaque coil configuration maintain and locate the radioactive radiation coil on the core wire thereby assuring positioning thereof on the core wire and accurate visualization via X-ray fluoroscopy.
摘要:
The guide wire comprises an elongated flexible shaft which is tubular. A helical coil assembly of radiopaque material comprises a first coil having a proximal portion threadedly force fitted into the tubular portion of shaft. A second coil has a proximal portion surrounding and threadingly engaging the distal portion of the first coil, and a distal portion terminating into a tip.

摘要:
The pressure measuring guide wire comprises an elongated flexible shaft with a lumen extending therethrough. The lumen is surrounded by a wall forming the shaft and the distal portion of which is provided with slots for pressure medium entry. The distal portion has a thickness, greater than the thickness of the proximal area of the shaft. A coil surrounds the proximal area of the shaft to compensate the difference in kinking resistance between the proximal and distal areas of the shaft.
摘要:
A docking assembly for the extension of a guidewire. The docking assembly comprises a plug formed at the proximal end of the guidewire, and a socket formed of a tubing permanently bent so as to have a V shaped portion comprised between two straight portions. The end of straight portion is affixed to the distal end of extension wire. A sleeve is slidably engaged over the tubing to substantially straighten it and facilitate insertion of plug into the tubing. Removal of sleeve allows the tubing to recover its preshaped deformation, thereby assuring locking of plug in tubing. To release the assembly it suffices to pull the guidewire and extension wire oppositely to slip the plug out from the tubing.

An electrical pin receiving socket (2,102) is disclosed which includes a base portion (6,106) having side arms (8,108) extending upwardly to a top wall (10) or contact arms (112). Back-up springs are positioned proximate the contact arms and cooperate with the contact arms to ensure that the contact arms will electrically engage a mating pin. The base section (6,106) also includes printed circuit board contacts (20,30,120,130), where the contacts (20,30,120,130) are reversely bent under the base section (6,106) and then vertically downwardly to form printed circuit board contacts (26,36,126,136), thereby allowing the electrical pin receiving socket to move relative to the printed circuit board.
