    摘要: A member for piping and wiring to an end effector of a robot is discharged from a first wrist element into a void area in a position displaced from an axis c, being bent and loosened, and then guided to a hollow path. Any variance in a length of the piping/wiring member 30 due to rotations of second and third wrist elements is absorbed in this void area, so that twining round or scratching by a wrist can be prevented.

    摘要: A catheter for mapping and ablating comprises an elongated flexible body having a distal region and at least one lumen extending therethrough. A tip electrode is mounted on the distal region. The tip electrode has an exposed distal region having proximal and distal ends and an isolated region proximal to the exposed distal region. The isolated region has an outer surface provided with an electrically insulating and thermally conductive layer. A second electrode is mounted on the isolated region of the tip electrode. This mapping and ablation electrode arrangement provides discrete recording of electrical signals due to the relatively small exposed distal region while allowing the creating of larger lesions due to the large thermal mass provided by the isolated region.

    摘要: A charge control method by which batteries can be efficiently charged, even if the charging is aborted, as well as a computer which employs such a charge control method is provided. The charge to the main battery is started and then the charge to the,main battery is stopped when the amount of electric energy in the main battery reaches a predetermined value (steps 200 to 204). Next, the charge to the second battery is started and then the charge to the second battery is stopped when the amount of electric energy in the second battery reaches a predetermined value (steps 206 to 210). Next, the charge to the main battery is restarted and then the charge to the main battery is stopped when the amount of electric energy in the main battery reaches 100%. Thereafter, the charge to the second battery is restarted and then the charge to the battery is stopped when the amount of electric energy in the second battery reaches 100% (steps 212 to 222).

    摘要: A catheter particularly suitable for bipolar mapping and ablating comprises an elongated flexible body having a distal region and at least one lumen extending therethrough. A tip electrode is mounted on the distal region. The tip electrode has an exposed distal region having an outer diameter, a recessed central region having an outer surface proximal to the exposed distal region, and a proximal region having an outer diameter and an outer surface proximal to the central region. The recessed central region has an outer diameter less than the outer diameters of the exposed distal region and the proximal region. The central region and the proximal region are provided with an electrically insulating and thermally conductive layer over at least a portion of their outer surfaces. A ring electrode is mounted on the recessed central region. The ring electrode has an outer diameter less than the outer diameters of the exposed distal region and the proximal region. With this design, the exposed region of the tip electrode is in direct contact with the heart tissue, and thus senses both the local activation energy (near-field signals) at the point of contact with the heart tissue and far field activation energy (far-field signals) received by the exposed region through the blood. However, the recessed electrode is protected from direct contact with the heart tissue, but does contact with surrounding blood. The close proximity of the recessed electrode to the exposed region enables the recessed electrode to receive approximately the same far-field signals as the exposed region. However, the recessed electrode does not pick up the local activation potential (near-field signals) that are received by the exposed region. This design permits the creation of high resolution electrograms.

The carrier (29) and the output shaft (34) are formed as a unitary member, and a pin so driven as to extend between the portions (28A,28B) of the carrier (29) fabricated as the unitary member is used as the planetary shaft (30). Therefore, the planetary gear device (20) has a reduced number of components, can be produced easily and has high assembly accuracy.
