ABSTRACT:
A method of manufacturing angiographic catheters comprises providing a length of elastomeric tube of a predetermined outer diameter and braiding multiple strands of wire wrapping about its exterior. A bonding agent is applied to the wire wrapping in circumferentially extending bands to bond the strands to each other. Thereafter, the wire wrapping is ground away at predetermined spaced locations along the length of the elastomeric tube to provide a series of wire wrapped sections joined by non-wrapped sections with each of the wire wrapped sections having at least the ends thereof enclosed by at least portions of the circumferentially extending bands of bonding agent. An elastomer layer is located over both the wire wrapped sections and the non-wrapped sections throughout the length thereof. Subsequently, the coated length is severed into pieces with the pieces each constituting a wire wrapped section that forms a catheter body and a non-wrapped section joined to at least one end thereof to constitute a flexible catheter tip.
