摘要： The invention relates to an ablation apparatus for intracardiac treatments which comprises a high-frequency source whose power output is controlled in a power-or temperature-controlled mode. Ablation catheters which each comprise at least one energy-emitting pole can be used with the apparatus, the or each pole comprising at least one temperature sensor for measuring the temperature of a tissue. The temperature sensors of the poles are either thermistors or thermocouples. The instrument further comprises a sensor-detection system and corresponding devices by means of which the power output can be automatically regulated such that the power is regulated according to the actual catheter type. To that end, it is not necessary to use a specially coded catheter and no special manual operations are necessary for adjusting the catheter type.

摘要： The electrical connector (1) with a socket section (2) and a plug section (3) contains a clip (4) by which the pin (5) of the plug section (3) can be clamped in the axial direction and secured against unintentional withdrawal. In addition there is protection against contact with the live parts of the connector (1) which nevertheless permits the rotation of the clip (4) so that it can be closed and opened. Essentially, the plug section (2) has a sleeve (13) which surrounds the pin (5) externally and in spaced relationship to it and is rotatable in relation to the plug section (2), which sleeve (13) is of such an axial length and inner dimensions that, with the pin (5) inserted into the clip (4), the sleeve (13) is axially movably pushed in an axial direction onto the component serving to rotate the conical section (6) of the clip (4) and at the same time is coupled thereto in the direction of rotation. Rotating the sleeve (13) when the electrical connector is assembled can thus close the clip and contra-rotating it opens said clip, the conical section (6) then moving axially in relation to the sleeve but being also driven in the direction of rotation. At the same time, the sleeve (13) protects the pin (5) against undesired contact even when the connector (1) is disassembled.

摘要： An ablation catheter arrangement includes an ablation generator, a rinsing liquid source for providing a liquid for rinsing the treatment area in which ablation is performed, and an ablation catheter connectable to the ablation generator and to the rinsing liquid source. The ablation catheter has an ablation area, at least one rinsing opening, and a rinsing bath for supplying rinsing liquid to the treatment area. A blood pressure measurement device detects the intracardiac blood pressure over the liquid column of the rinsing liquid, and communicates with the rinsing channel of the ablation catheter by fluid connection.

摘要： Apparatus are provided for performing a procedure within a patient's body that include a tubular member including proximal and distal ends, a central axis or region extending therebetween, and a distal portion extending distally from an intermediate portion to the distal end. One or more accessory lumens and a steering element lumen extend between the proximal and distal ends, the steering element lumen offset from the central region within the distal portion such that a steering plane intersects the steering element lumen and the central axis. The distal portion includes a core member extending between the intermediate portion and the distal end, and stabilization elements embedded in the core member adjacent the accessory lumen and defining a stabilization plane that intersects the steering plane at a location offset from the central region, e.g., closer to the accessory lumen than the steering element lumen.
