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.

Dissipation device and MRI-safe catheter system

An implant for releasing an active substance into a vessel through which a body medium flows. The implant release an active substance into a vessel through which a body medium flows downstream from the location of the implant. A base of a biodegradable material is a carrier of the active substance to be released. The body medium flows past the implant and the active substance is release. The implant is configured so that the active substance does not contact a vessel wall at the location of implant.

Implant for releasing an active substance into a vessel through which a body medium flows

A lead for use in Deep Brain Stimulation (DBS) and similar applications has a rigid lead tip with multiple electrodes thereon. The electrodes are formed by coating a lead tip core with a conductive material; selectively removing the conductive material to define the electrodes and conductive tracks leading therefrom; and then applying a layer of insulating material over the tracks to leave the electrodes exposed. Terminals are also left exposed on the tracks for connection to energy supply and/or data transmission lines. Such lines are preferably provided on or within a flexible lead body connected to the lead tip.

Multi-electrode leads for brain implantation

The invention concerns a fixing for implantable electrodes and catheters. The object of the present invention is inter alia to provide a fixing which takes account of the different demands in the course of time of ordinary use of the implantable electrodes or catheters. For that purpose the fixing includes at least one first structural element comprising a biodegradable material, namely a biodegradable magnesium alloy.
