Title: Method and apparatus for advancing catheters
Inventor: EGGERS PHILIP E
IPC: A61B18/14
Filed: 1992-12-28
Granted: 2001-02-20
Abstract: A catheter comprises a catheter body (10) having a proximal end, a distal end, and an electrode array disposed near he distal end (12). The electrode array includes a plurality of isolated electrode terminals (18). The electrode array and a common electrode (16) are connected to a high frequency power supply (32) anc9 the common electrode (16) may be located on the catheter, may be secured separately to a patient's skin, or may be formed as part of a movable guidewire. By contacting the electrode array against a target location in the patient's body, the target location may be selectively heated, with the current density being contacted at the points of contact between the electrode terminals (18) and the tissue or stenotic material. For example, by positioning the common electrode within a stenotic region and contacting a leading surface of the stenotic region with the electrode array, the stenotic material can be heated by applying a high frequency voltage between the electrode array and the common electrode. The stenotic region can thus recanalized by advancing the distal end of the catheter body through the heated stenotic material.

Abstract: [Abstract]          [Object]    In a pipetting apparatus for pipetting a sample with a nozzle,  imperfect nozzle clotting condition can be detected in addition to perfect nozzle clotting condition.          [Structure]    The pressure in the air hose 12 connected to the nozzle 10 for aspirating a sample 18 is detected by the pressure sensor 20, and the detected pressure value is transmitted to the clot detecting section 26.   In this clot detecting section 26, a plurality of pressure calculation periods are set to calculate the pressure difference in each of the calculation periods.          When at least one of the calculated pressure differences exceeds at least one of the predetermined threshold values corresponding to the calculation periods respectively,  a clot alarm is generated.  Since a plurality of the pressure calculation periods are set,  an imperfect clotting condition can be detected in addition to the perfect clotting condition,  thus improving pipetting accuracy.

IPC: B65H23/195
Filed: 1996-08-12
Granted: 1999-07-27
Abstract: A paper magazine which can feed paper from a paper roll at high speed with high accuracy. Provided between a drive shaft and a paper feed roller are a normal rotation transmission for transmitting only the rotation of the drive shaft in the normal direction to the feed roller and a reverse rotation transmission for transmitting only the rotation of the drive shaft in the reverse direction to the feed roller. A rotation transmission mechanism is provided between the drive shaft and a core for nonrotatably supporting a paper roll to transmit both the normal and reverse rotations of the drive shaft to the core. To feed paper from the paper roll, the feed roller and the core are rotated in the paper feed direction, while controlling the rotating speed of the core so that the peripheral speed of the feed roller is higher than the peripheral speed of the paper roll when its diameter is maximum to apply suitable tension to the paper being fed. To rewind paper on the paper roll, the feed roller and the core are rotated in the paper rewinding direction, while controlling the rotating speed of the core so that the peripheral speed of the feed roller is lower than the peripheral speed of the paper roll when its diameter is minimum to apply suitable tension to the paper being rewound.
