Abstract

A dissipation device having a proximal end, which is located outside the body, and a distal end, which is suited in particular for elongate medical instruments, in particular electrophysiological catheters or temporary electrode leads, placed temporarily in the body. The dissipation device including a dissipation sleeve which extends from the proximal end to the distal end of the dissipation device, and a lumen which extends from the proximal end to the distal end, and in which the instrument can be displaceably guided, wherein the lumen is enclosed by the dissipation sleeve. The dissipation device is characterized in that the dissipation sleeve is composed, at least partially, of electrically conductive material, and/or the dissipation sleeve includes dissipation means composed of electrically conductive material and, therefore, the dissipation sleeve is designed to dissipate or divert electrical energy induced by electromagnetic radiation.
