Title (EN) CONTRACEPTIVE SYSTEM AND METHOD OF USE
(FR) SYSTEME CONTRACEPTIF ET SON PROCEDE D'UTILISATION
Abstract:
(EN) A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory response or to deliver a drug.
(FR) Dispositif et procédé d'utilisation d'un système de contraception ou de stérilisation, et notamment de contraception à procédure réversible, permettant d'occlure un lumen reproducteur pour empêcher le passage des cellules reproductrices dans ce lumen sur une période désirée jusqu'à ce que le patient souhaite recouvrer ses fonctions reproductrices, le passage du lumen étant alors rouvert. L'élément d'occlusion comprend de préférence une structure tubulaire formée dans un matériau à mémoire de forme conçu pour être implanté dans un lumen reproducteur. Cet élément d'occlusion est implanté dans un lumen du corps, et fixé à la paroi de ce lumen reproducteur, puis est replié de façon à provoquer l'affaissement de la paroi et, par conséquent, l'occlusion du lumen. Selon une autre variante, l'élément d'occlusion peut être replié sur un bouchon solide. Le lumen reproducteur peut être rouvert par introduction d'un cathéter à ballonnet et par une série de gonflements du ballonnet, redilatant ainsi l'élément d'occlusion affaissé, ou par le retrait du bouchon. L'élément d'occlusion et le bouchon peuvent être conçus de façon à faciliter l'endothélialisation, provoquer une réponse inflammatoire ou administrer un médicament.
