CATHETERS AND RELATED DEVICES AND METHODS OF MANUFACTURE

Abstract: a catheter incorporating a thin film polymeric layer or layers. the thin film may have a wall thickness of about 0.00025″+/−less than 0.0001″ to about 0.0015″+/−0.0002″, for example. the thin film may be formed by extruding a sheet and cutting the sheet into elongate ribbons, each having two opposing long edges. the ribbon may be rolled or wrapped to define a tubular shape with a gap between the long edges. heat and pressure may be applied to close the gap, abut the edges and form a longitudinal joint. the joint may extend along a portion of the length of the tubular shaft or most of the length of the tubular shaft. the tubular-shaped thin film layer may have a uniform wall thickness around the circumference, and the uniform wall thickness may
