A vasoocclusive member, such as embolic coil, that mechanically joins an instrument for delivering that vasoocclusive member to a selected site within the vasculature or other lumen of a human body via the use of a catheter is provided. A thermoplastic member augments the junction to enhance variously the friction at and integrity of the junction. Once the vasoocclusive member is delivered to the desired site, radio frequency energy is supplied to the thermoplastic member in an amount sufficient to soften the thermoplastic member, allowing mechanical disengagement to then take place.
L'invention concerne un élément d'occlusion vasculaire, tel un serpentin embolique, reliant mécaniquement un instrument d'apport dudit élément d'occlusion vasculaire à un site sélectionné à l'intérieur du système vasculaire ou d'une autre lumière du corps humain, au moyen d'un cathéter. L'élément thermoplastique améliore la jonction pour augmenter de diverses manières le frottement au niveau de la jonction et l'intégrité de celle-ci. Une fois l'élément d'occlusion vasculaire délivré sur le site voulu, l'énergie à radiofréquence est transmise à l'élément thermoplastique en une quantité suffisante pour ramollir l'élément thermoplastique, ce qui permet alors d'obtenir un détachement mécanique.
