    摘要: A medical balloon having a resistance to circumferential tearing comprises a substantially cylindrical portion disposed between first and second tapered portions that have a decreasing cross-sectional area along a length thereof away from the cylindrical portion. The substantially cylindrical portion includes first and second end portions and a midsection disposed therebetween. The midsection includes a first region having a first resistance to tearing and a second region having a second lower resistance to tearing, where the second region extends about only a portion of the circumference of the cylindrical portion and does not extend beyond the midsection.

    摘要: A medical device (110) including a catheter shaft (111) and a unitarily and continuously formed portion (108) having a varying durometer, and optionally including an expandable balloon (18, 118). One or both of the unitarily and continuously formed portion (108) and the balloon (18, 118) are made from an irradiation cross-linked or cross-linkable mixture of a polyamide elastomer and at least one additional cross-linking reactant. The polyamide elastomer can be a polyester amide, a polyether ester amide or a polyether amide, and is preferably a nylon block copolymer. The aromatic molecule can be 1,3,5 triethyl benzene; 1,2,4 triethyl benzene; and 1,3,5 triisopropyl benzene. The cross-linking reactant can be: (a) a difunctional material, (b) a trifunctional material, (c) a tetrafunctional material, or (d) an aromatic molecule containing at least two ring substituents, each of the ring substituents having labile hydrogens at a benzylic site therein. The cross-linking reactant can also be diallyl phthalate or meta-phenylene dimaleimide.

    摘要: A radially expandable stent (10) made from a cannula or sheet of biocompatible material that includes at least one longitudinal segment (14) comprised of a series of laterally interconnected closed cells (13). Each closed cell of a longitudinal segment is defined laterally by a pair of longitudinal struts (15, 16) that are interconnected at each end by a circumferentially adjustable member (19, 20). When the stent is expanded using a balloon (47), the opposing circumferentially adjustable members deform to allow circumferential expansion of the longitudinal segment, while the length of the segment, as defined by the longitudinal struts, is maintained. Self-expanding versions of the stent utilize a nickel-titanium alloy. Adjacent longitudinal segments are joined by flexible interconnection segments (21) that permit the stent to bend laterally. The flexible interconnection segment is comprised of curvilinear struts (22, 23) that form a series of serpentine bends (81) that distribute lateral bending forces. In a preferred embodiment, a short strut interconnects longitudinal segments and an adjacent interconnection segment. Each interconnection strut attaches to the longitudinal segment within a region (27) at the end (17) of a longitudinal strut (15) dividing two adjacent closed cells.
