Abstract

Electrode structures are formed from flexible, porous, or woven materials. One such structure is made by forming first and second body sections, each including a peripheral edge. The first and second body sections are joined together about their peripheral edges with a seam, 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.
