    摘要： A fluid conduit includes a flexible member having a tubular wall and a plurality of geometric segments located adjacent to the tubular wall. The geometric segments are disposed about a central axis of the conduit and spaced apart relative to each other to define a gap therebetween. The gap is sized to be closed by contact between adjacent geometric segments upon a predetermined flexure of the flexible member. A method of forming the conduit includes forming a flexible member with a tubular wall and forming a plurality of grooves about the central axis in the tubular wall. The geometric segments in one embodiment are formed from the intersections of a first plurality of helical grooves formed at a first angle relative to the central axis and a second plurality of helical grooves formed at a second angle mutually opposite from the first angle.

    摘要： A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.

    摘要： An apparatus and method for uniformly irradiating a strand of plastic material by twisting the strand as it is advanced in a plurality of paths transverse to an electron beam. A set of pinch rolls are positioned on opposites ends of the electron beam generator to advance and twist the strand. Lift cams periodically release the twist on the strand at positions of maximum twist by forcing the pinch rolls apart. Each set of pinch rolls includes upper and lower rolls adjacent a medial roll which, in turn, is driven in alternating axial directions to impart twist to the strand. The medial rolls are driven in alternating axial directions by a cammed surface thereon and a cam follower and synchronized to move 180.degree. out of phase from each other. A series of three spaced apart idler rolls are also provided to form a tandem figure-eight pattern in side view for the strand to compensate for reel set in the strand.
