Abstract
The present invention includes catheters and catheter shafts having a curved portion, for example, a curved distal portion. The curved distal portion may be formed by subjecting the distal portion, which might include one or more polymeric segments or layers, to heat at or above the melt temperature thereof. Heating at or above the melt temperature may to reduce residual stress and eliminate heat history.
