Title
(EN) ELECTRODE STRUCTURES FORMED FROM FLEXIBLE, POROUS, OR WOVEN MATERIALS
(FR) STRUCTURES D'ELECTRODES FORMEES A PARTIR DE MATERIAUX FLEXIBLES, POREUX OU TISSES
Abstract
(EN)
Electrode structures (20) are formed from flexible, porous, or woven materials. One such structure is made by forming first and second body sections (225), each including a peripheral edge. The first and second body sections (225) are joined together about their peripheral edges with a seam (224), thereby forming a composite structure. Another one of such structures is made by forming a body having a three-dimensional shape and opposite open ends, and at least partially closing at least one of the opposite ends by forming a seam. Another one of such structures is formed from a sheet of material having peripheral edges. The sheet is placed on the distal end of a fixture, while the peripheral edges of the sheet are gathered about the proximal end of a fixture, thereby imparting to the sheet a desired shape. At least one pleat is formed to secure the gathered peripheral edges together. The seams or pleats are formed by thermal bonding, or ultrasonic welding, or laser welding, or adhesive bonding, or sewing.

L'invention concerne des structures d'électrodes (20) formées à partir de matériaux flexibles, poreux ou tissés. Une structure de ce type est réalisée en formant des première et deuxième sections de corps (225) comportant chacune un bord périphérique. Les première et deuxième sections de corps (225) sont assemblées l'une avec l'autre autour de leurs bords périphériques par une couture (224), formant ainsi une structure composite. On réalise une autre structure de ce type en formant un corps présentant une forme tridimensionnelle et des extrémités ouvertes opposées, et en fermant, au moins partiellement, au moins une des extrémités opposées par une couture. Une autre structure de ce type est formée à partir d'une feuille de matériau comportant des bords périphériques. La feuille est placée sur l'extrémité distale d'un dispositif, tandis que ses bords périphériques sont rassemblées autour de l'extrémité proximale d'un dispositif, ce qui confére ainsi à la feuille une forme requise. Au moins un repli est formé pour fixer ensemble bords périphériques rassemblés. Les coutures ou les plis sont formés par soudage thermique, soudage par ultra-sons, soudage au laser, ou par collage ou couture.
