Abstract:
1. A catheter device comprising: an elongated outer member having a proximal end and a distal end connected together by an intermediate joint a proximal portion extending between said proximal end and said intermediate joint and having a midpoint, and a distal portion located between said intermediate joint and said distal end, a plurality of fenestrations located in said distal portion extending from said distal end to a midpoint of said distal portion, said plurality of fenestrations defining a plurality of resultant beams and a plurality of rings located in said distal portion along a length of said elongated outer member, said plurality of tings extending about a portion of the circumference of said elongated outer member such that said plurality of tings extend within a plane that is perpendicular to a longitudinal axis of said elongated outer member, said plurality of resultant beams extending parallel to the longitudinal axis between said plurality of rings, said elongated outer member having an outer surface and an interior surface extending from said proximal end to said distal end, wherein said proximal end of said elongated outer member is formed from a first stock material, said distal end of said elongated outer member is formed from a second stock material, and said first stock material and said second stock material are different materials; and an outer elastomer laminate layer completely filling said plurality of fenestrations located in said elongated outer member such that said plurality of resultant beams and said plurality of rings are completely encapsulated within said outer elastomer laminate layer, said filled fenestrations forming a first lumen at least partially extending along an axis of said elongated outer member from said proximal end to said distal end of said elongated outer member, wherein said distal portion of said elongated outer member has a curved shape relative to said distal end, said distal portion has a first plurality of fenestrations and a second plurality of fenestrations and said curved shape of said distal portion of said elongated outer member relative to said distal end is held by bending said elongated outer member such that said first plurality of fenestrations are smaller than said second plurality of fenestrations prior to filling said fenestrations with said outer elastomer laminate layer such that said second plurality of fenestrations are filled with said outer elastomer laminate layer to be larger than said first plurality of fenestrations.
