Abstract
A body () for a catheter or sheath is disclosed. The body () includes strips () formed longitudinally from the proximal () portion of the body () to the distal () portion of the body (). The strips are formed of different materials. The strips can have different radiopacities, or can be splittable/peelable. The splittable/peelable body comprises a peel mechanism longitudinally extending along its respective length. The peel mechanism can be formed by longitudinally extending regions of interfacial bonding between first and second longitudinally extending strips of polymer material. A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the body () along its peel mechanism. The polymer material of the first strip () can have a greater amount of radiopaque filler than the polymer material of the second strip (). Each strip forms at least a portion of an outer circumferential surface of the body ().
