The present invention provides a self-withdrawing catheter device for injection of material into a body passageway, comprising: a) a highly-flexible elongated shaft including at least one injection channel, attachable to a syringe; b) a canopy attached to the shaft near the distal end, the canopy providing smooth self-withdrawal of the catheter from within a body passageway, due to backward fluid pressure exerted upon said canopy after injection of material through said catheter. The invention also provides a surgical method and kit for fistular repair, comprising the afore-mentioned catheter, an additional balloon catheter for injecting fluids to clear a fistula, a debriding brush, a guide wire for aiding in inserting the components into the fistula, and hooks and ties for connecting these elements and drawing them into the fistula.
La présente invention concerne un cathéter à retrait automatique permettant d'injecter une substance dans une voie corporelle. Ce cathéter comprend: a) un tube allongé hautement flexible, comprenant au moins un conduit d'injection, pouvant être assemblé à une seringue; b) une calotte fixée sur le tube à proximité de l'extrémité distale, cette calotte permettant un retrait automatique aisé du cathéter hors d'un passage corporel, grâce à la pression du fluide s'appliquant vers l'arrière sur ladite calotte après l'injection d'une substance à travers le cathéter. L'invention concerne également une méthode chirurgicale, et une trousse de réparation de fistules, contenant ledit cathéter, un cathéter additionnel à ballonnet permettant l'injection de fluides permettant de dégager une fistule, une brosse de débridement, un fil-guide facilitant l'introduction les éléments dans la fistule, et des crochets et des attaches permettant de fixer ces éléments et de les tirer dans la fistule.
