CA 2619410

A device for implantation in the vasculature of a patient can include a fixation mechanism for anchoring the device in place while allowing for easy removal of the device. The fixation mechanism can include a detachable and/or biodegradable portion that can allow for removal from the bulk of the device in order to allow for the bulk to simply be pulled from the body without likelihood of injury. These devices also can include electrode assemblies that do not promote fibrous ingrowth, further reducing the likelihood for injury upon extraction of the device.

L'invention concerne un dispositif destiné à réaliser une implantation dans le système vasculaire d'un patient et pouvant comprendre un mécanisme de fixation servant à ancrer le dispositif tout en permettant un retrait facile de ce dispositif. Le mécanisme de fixation peut comprendre une partie amovible et/ou biodégradable pouvant permettre un retrait à partir du corps du dispositif, le corps pouvant ainsi être simplement extrait par traction sans risque de lésion. Ces dispositifs peuvent également comprendre des ensembles électrodes ne favorisant pas la croissance fibreuse, d'où une réduction supplémentaire du risque de lésion lors de l'extraction du dispositif.
