    Abstract: The assembly comprises two or more catheter tubes fused together to form a fused catheter bundle. Each tube has at least one lumen extending longitudinally through the catheter from its distal end to its proximal end and wherein at least one of said tubes comprises a pressure resistant lumen. The tubes are fused together by use of heat & pressure generated by heat shrinkable tube slides positioned over a segment of the catheter tubes while mandrels are positioned within each tube lumen. After cooling, the heat shrinkable tube may be removed and the mandrels removed such that and the fused catheter bundle is formed. One or more of the tubes may be of a different hardness, material and/or color. A distal end of the fused catheter bundle can be split free floating, stepped or tapered tipped. A non fused portion may form catheter extension legs.

    Abstract translation: 该组件包括两个或更多个导管，它们融合在一起以形成融合的导管束。 每个管具有至少一个从其远端到其近端的纵向延伸通过导管的内腔，并且其中至少一个管包括耐压腔。 通过使用由定位在导管管段上的热收缩管滑块产生的热和压力将管熔合在一起，而心轴位于每个管腔内。 在冷却之后，可以去除热收缩管并且去除心轴使得形成熔融的导管束。 一个或多个管可以具有不同的硬度，材料和/或颜色。 熔融导管束的远端可以自由浮动，阶梯式或锥形分离。 非融合部分可以形成导管延伸腿。

    Abstract: A gasket assembly (20) and method for forming the gasket assembly (20) for sealing two mating surfaces (46,48) over a complex geometrical contact region. The gasket assembly (20) is formed by a hollow silicone rubber tube (22) having a naturally straight configuration but easily bent into complex configurations without kinking. The tube (22) is filled with a curable liquid rubber compound (30) and then the ends (24,26) of the tube (22) are joined in end-to-end fashion to form a continuous loop. The joined ends (24,26) of the tube (22) can be reinforced with a connector (34,134) and then locally cured on a preliminary operation so that the liquid rubber compound (30) does not escape. The tube (22) is then laid up in a mold (40) having a complex geometrical feature (42) which replicates the complex geometrical contact region of the two mating surfaces (46,48) to be subsequently sealed. With the tube (22) held stationary in the mold form (40), the entrapped liquid rubber compound (30) is cured using a heat source (44) or other suitable curing accelerant. Once fully cured, the core of rubber compound (30′) takes a set in the complex geometrical form, and resists straightening of the tube (22) so as to hold the gasket assembly (20) in the complex geometrical shape required to later seal the mating surfaces (46,48). The tube (22) and core of cured rubber compound (30′) may be selected of materials which possess different durometers.
