摘要： The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure.

摘要： The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus. The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. The ring-shaped elements may be metallic and may be bonded with a resilient, flexible elastomeric adhesive, wherein the ring-shaped elements may have different lengths and may be fused closer or further apart to one another depending on the characteristics of a portion or section of the tubing. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. The ring-shaped elements may be truncated to provide a bending bias. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure. In yet another aspect of the invention, some of the ring-shaped elements may be radiopaque, or the ring-shaped elements may comprise of different colors to operate as indicators along the tubular structure.
摘要翻译：本发明主要针对适于插入身体组织或空腔的医用管道以及沿管道长度制造管道的不同变化的方法。管道包括多个单独的离散的大体环形元件，其串联布置并且熔合或粘合在一起形成连续的管状结构。环形元件可以由热塑性材料或热固性材料形成。环形元件可以包括沿着管状结构的长度组装的塑料环，金属环，未增强塑料环和/或金属增强塑料环，以提供可变的柔性和抗扭结性。管状结构可以具有任何几何形状的横截面，并且其可以弯曲，扭曲或弯曲而没有扭结。环形元件可以具有不同的弯曲模量。环形元件可以包括沿着管状结构的不同部分或部分组装的柔性和刚性环形元件的组合。环形元件可以是金属的并且可以用弹性的柔性弹性体粘合剂粘合，其中环形元件可以具有不同的长度，并且可以根据部分或部分的特性彼此靠近或更远地彼此熔合的管道。在本发明的另一方面，医疗管道还可包括用于控制管状结构的次管腔和拉线。环形元件可以被截断以提供弯曲偏压。在本发明的另一方面，环形元件可以在管状结构的不同部分或部分中的直径和/或组成变化。在本发明的另一方面，一些环形元件可以是不透射线的，或者环形元件可以包括不同的颜色以作为沿着管状结构的指示器。

摘要： A surgical guidewire having a distal section and a proximal section includes a core with a first end and a second end. A longitudinal spring disposed circumferentially of the core has a first end coupled to the second end of the core and a second end which extends distally of the core. A sheath has a spaced sliding relationship with at least a portion of the spring and a frictional fixed relationship with at least a portion of the core. An associated method of manufacture includes the step of selecting from a group of sheaths having different characteristics but a common inside diameter, a particular sheath desired for the guidewire.
摘要翻译：具有远侧部分和近端部分的外科导丝包括具有第一端和第二端的芯。设置在芯的周向的纵向弹簧具有联接到芯的第二端的第一端和沿芯的向远侧延伸的第二端。护套与弹簧的至少一部分具有间隔开的滑动关系，并且与芯的至少一部分具有摩擦固定关系。相关联的制造方法包括从具有不同特性但具有共同的内径的鞘组中选择所需的特定护套的步骤。
