A polymeric heat shrinkable tubular sheath for mounting about a balloon on a dilatation catheter by heat treating at a temperature which does not detrimentally effect the properties of the balloon to shrink the sheath onto the balloon. The tubular sheath is preferably heated to a temperature above body temperature, e.g. 40 < 100 ~C, preferably less than 85 ~C, to heat shrink the sheath onto the balloon. A presently preferred polymeric material is a copolymer of ethylene (75 %) and methyl acrylate (25 %). The heat shrinkable sheath has an inner lumen with minimum dimensions large enough to facilitate the advancement of the sheath over the exterior of a dilatation balloon without the need for a great deal of manual manipulation by the physician or other operator prior to heat shrinking.

La présente invention concerne une gaine polymère tubulaire thermorétractable se montant autour d'un ballonnet installé sur un cathéter de dilatation. Le montage s'effectue en soumettant la gaine à une température qui, sans porter atteinte aux propriétés du ballonnet, fait se rétracter la gaine sur le ballonnet. La gaine tubulaire se chauffe de préférence à une température supérieure à la température corporelle, par exemple, une température comprise entre 40 ·C et 100 ·C, de préférence inférieure à 85 ·C, et suffisante pour provoquer la rétraction de la gaine sur le ballonnet. Actuellement, l'un des matériaux polymères préférés est un copolymère d'éthylène (75 %) et de méthylacrylate (25 %). La lumière intérieure de cette gaine thermorétractable est de dimensions au moins assez grandes pour favoriser la progression de la gaine par dessus l'extérieur du ballonnet de dilatation sans nécessiter du médecin ou de l'intervenant des manipulations plus ou moins importantes avant le thermorétraction.
