Abstract
Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions.

38. A medical device comprising:
-
a longitudinally extending tube having a wall portion and a lumen extending for at least a portion therethrough;
the tube having at least one fenestration extending through the wall portion; and
polymer film covering at least a portion of the at least one fenestration. - View Dependent Claims (39, 40, 41, 42)

43. Catheter comprising a first longitudinally extending hollow polymer tube having a proximal end, a distal end, a wall having an inner surface and an outer surface, and a centrally located lumen extending from the proximal end to the distal end;
-
a channel located in the wall forming an opening in the outer surface of the wall and extending from the proximal end to the distal end; and
polymer film covering the channel from the proximal end to the distal end, thus covering the opening in the outer surface and forming a first wall lumen extending from the proximal end to the distal end. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79)
