CA 2220181

Manufacturing processes for apparatus, including slotted hypotube, for use as a catheter, a guidewire, a catheter sheath for use with catheter introducers or a drug infusion catheter/guidewire is disclosed. The manufacturing process includes creating a pattern of slots or apertures in a flexible metallic tubular member, by processes including but not limited to, electrostatic discharge machining (EDM), selective chemical etching, ablation and laser cutting. These slots or apertures may be cut completely or partially through the wall of the flexible metallic tubular member. These manufacturing processes may include the additional step of encasing the flexible metallic member such that a fluid tight seal is formed around the periphery of the tubular member.

L'invention concerne des procédés de fabrication d'appareils, par exemple un hypotube à fentes, utilisé sous forme de cathéter, de fil-guide, une gaine de cathéter utilisée avec des dispositifs d'introduction de cathéter ou un cathéter/fil-guide pour l'administration de médicaments par perfusion. Ce procédé de fabrication consiste à créer une structure de fentes et d'ouvertures dans un élément tubulaire métallique flexible au moyen de procédés comprenant entre autres l'usinage par décharge électrostatique, l'attaque chimique sélective, l'ablation et le découpage au laser. Ces fentes ou ouvertures peuvent être découpées complètement ou partiellement à travers les parois de l'élément tubulaire métallique flexible. Ces procédés de fabrication peuvent également comprendre l'étape supplémentaire consistant à gainer l'élément métallique flexible de façon à créer une étanchéité aux fluides à la périphérie de l'élément tubulaire.
