摘要：
Infusion balloon catheter (100, 200) with fortified proximal infusion outlet port (106, 206), and manufacturing thereof. Infusion balloon catheter includes: inflatable balloon member (102, 202)； shaft (101, 201) having distal end (103, 203) attached to balloon member, and shaft wall enclosing: first lumen (104, 204) providing passage to balloon inflation fluid, and second lumen (105, 205) providing passage to infusion fluid and guidewire (GW)； and bending-resistant insert member (107, 207, 300a-f, 400a-b) housed in second lumen and located proximally to balloon member, insert member is affixed to, and conforms to shape of, shaft inner wall surface, and includes one or more opening(s) (108, 208). Shaft wall has infusion outlet port located along, and providing opening to, second lumen proximally to balloon member. Insert opening(s) is/are in direct fluid communication with infusion outlet port whose cross-sectional area is larger than that of infusion inlet opening. Bending-resistant insert member provides fortifying structural support to shaft wall portion surrounding infusion outlet port. Applicable to medical procedures involving injection of imaging contrast material or/and drugs.La présente invention concerne un cathéter de perfusion à ballonnet (100, 200) présentant un orifice de sortie de perfusion proximal renforcé (106, 206), et la fabrication de celui-ci. Le cathéter de perfusion à ballonnet comprend : un élément gonflable formant ballonnet (102, 202), un corps (101, 201) ayant une extrémité distale (103, 203) fixée à l'élément formant ballonnet, la paroi du corps entourant : une première lumière (104, 204) permettant le passage du fluide de gonflage du ballonnet, et une deuxième lumière (105, 205) permettant le passage du fluide de perfusion et du fil guide (GW)； et un élément rapporté résistant à la flexion (107, 207, 300a-f, 400a-b), logé dans la deuxième lumière et situé du côté proximal de l'élément formant ballonnet, ledit élément rapporté étant fixé
