Title
(EN) CATHETER-CUM-BALLOON
(FR) CATHETER MUNI D'UN BALLON
Abstract
(EN)
This invention relates to a catheter-cum-balloon characterized in that the balloon is reinforced with composite yarns composed of elastic yarns and non-elastic ones which are each larger than the elastic one in free length. In the catheter-cum-balloon of the present invention, expandability of the balloon is high and thus, when inserted into or pulled out from the blood vessel for the purpose of therapy, the balloon is capable of not only decreasing in diameter without development of creases but also positively expanding to the same size and the same shape at any time. Accordingly, provided are such advantages that: reliability in therapy is increased; an opening incised for therapy, even if small, satisfies the purpose; treatment and care after operation are simple, requiring only a few length of time until cure; and the burden inflicted on the patient and nurse daily is light.
(FR)
Cathéter muni d'un ballon, caractérisé par le fait que le ballon est renforcé avec des fils composites composés de fils élastiques et de fils non élastiques, la longueur libre de ces derniers étant supérieure à celle des premiers. Dans le cathéter ci-décrit, le ballon présente une forte capacité de dilatation et, par conséquent, lorsque le cathéter est introduit dans un vaisseau sanguin ou en est extrait à des fins thérapeutiques, le ballon peut subir une réduction de diamètre sans former de faux plis et peut se dilater à nouveau à tout moment jusqu'à reprendre la même forme et les mêmes dimensions. Ce cathéter présente les avantages suivants: il accroît la fiabilité de la thérapie; il ne requiert qu'une petite incision pratiquée à des fins thérapeutiques; il permet de simplifier le traitement et les soins post-opératoires, ce qui raccourcit la durée de la convalescence; finalement, il réduit l'inconfort du patient, ainsi que la charge de travail du personnel soignant.
