Abstract
(EN)
An improved fastener apparatus includes an outer sleeve which is moved into a patient's body tissue. A distal end portion of the outer sleeve is expanded in the patient's body tissue. An inner sleeve is moved axially through the outer sleeve and a distal end of the inner sleeve is expanded in the patient's body tissue. The fastener apparatus may be provided with an external thread convolution on either or both of the inner and outer sleeves. During expansion of the distal end portion of either the inner or outer sleeve, a proximal end portion of the outer sleeve may be gripped and pulled to offset forces applied to the distal end portion of one of the sleeves. Although inner and outer sleeves may advantageously be utilized, the fastener apparatus may be constructed with only a single sleeve if desired.
(FR)
L'invention concerne un appareil de fixation amélioré comprenant un manchon externe qui est déplacé dans le tissu cellulaire d'un patient. Une partie d'extrémité distale du manchon externe est dilatée dans le tissu cellulaire du patient. Un manchon interne est déplacé axialement à travers le manchon externe et une extrémité distale du manchon interne est dilatée dans le tissu cellulaire du patient. L'appareil de fixation peut être pourvu d'une convolution de filetage externe sur l'un ou l'autre des manchons interne et externe, ou sur les deux. Pendant la dilatation de la partie d'extrémité distale de l'un ou de l'autre du manchon interne ou du manchon externe, une partie d'extrémité proximale du manchon externe peut être saisie et tirée pour déplacer les forces appliquées à la partie d'extrémité distale de l'un des manchons. Bien que les manchons interne ou externe puissent être avantageusement utilisés, l'appareil de fixation peut être construit si on le souhaite avec un seul manchon.
