摘要： In one of its aspects, the invention provides a catheter of a selected length, and having a main body of a first cross-section and a tip section of smaller cross-section, the tip section being formed integrally with the main body from a catheter blank having a length less than the selected length. Also, in another of its aspects, the invention provides a method of making a catheter tip on a main body of thermoplastic synthethic plastics material and having a first cross-section. A progressive forming technique is used to reduce the cross-section of the body to create a tip section of smaller cross-section.

摘要： A tearaway introducer sheath assembly (10) for use in implantation of a catheter into a patient, having an elongated polytetrafluoroethylene sheath tube (12) and a proximal polyethylene hub component (16). The hub comprises two halves (22) insert molded about the sheath tube proximal end and joined to each other by frangible webs (28) enabling manual splitting. At least one pair of opposed holes (42) is formed through the tube proximal end portion 44, and a polyethylene liner (46) is inserted into the tube's proximal end portion. The polyethylene flows into the at least one pair of holes (42) to fuse with the liner, establishing a pair of physical joints (50′) integrally joining the liner (46) to a respective hub half (22). Upon manual splitting of the hub halves, the sheath tube easily splits along its length as a result of a property of the polytetrafluoroethylene material.

摘要： A tearaway sheath assembly (100) having a splittable sheath tube (102) a splittable hub (110), a split valve (150,250) and a split cap (180). The valve (150,250) has a slit (158,258) at least partially across the transverse distal section (154) such that transverse distal section may be displaced laterally during insertion through the slit (158,258), of a dilator (200) or a catheter. The valve (150,250) is formed in two separate halves (152A,152B;252) that are fused or adhered to each other to form a sealed weak bond (154) that is easily broken during splitting of the sheath; each valve half is mechanically affixed in a proximal valve-receiving recess (130) of the hub such as by anchor posts (136) extending through apertures (166A,166B) in ears (164A,164B) of each valve half. A two-part cap (180) is affixed to the hub proximal end (120) and traps the valve between itself and the hub. Pairs of opposed gaps (184,122) of the cap (180) and the hub (110) are aligned with lines of weakness or seams (106) of the sheath tube (102) and the weak bond (154) of the valve, facilitating splitting of the assembly (100) when desired by the practitioner to peel it away from the inserted catheter.

摘要： A multiple catheter assembly (100) including a first catheter (110) having a first proximal end region (112), a first distal end region (114) terminating in a first distal tip (116), and an outer surface (120) defining at least a first lumen (122) extending longitudinally therethrough between a first distal and a first proximal opening. The assembly (100) also includes a second catheter (130) having a second proximal end region (132), a second distal end region (134) terminating in a second distal tip (136), and a second outer surface (140) defining at least a second lumen (142) extending longitudinally therethrough between a second distal and a second proximal opening. The first (122) and second (142) lumens are independent from each other for facilitating simultaneous flow in opposite directions. The outer surfaces (120,140) of the first and second catheters are releasably joined for allowing the first and second distal tips (116,136) and first and second proximal end regions (112,132) to be at least partially longitudinally split from each other. A method of inserting the catheter assembly (100) is also provided.

摘要： A catheter assembly (10) having a catheter (12) with lumens (20a,20b), extension tubes (14a,14b) and a hub (16). Distal ends (36) of the extension tubes and the proximal end (24) of the catheter are secured in and to the hub. Fittings (50) are first affixed in the distal ends of the extension tubes and have annular collars (56) that are embedded in the hub when the hub is molded over the distal ends of the extension tubes during manufacturing. An array of annular barbs (60) secure the cylindrical portion (52) of each fitting in the respective extension tube distal end (36).

摘要： A steerable medical catheter is provided having a polymeric main shaft with a plurality of lumen extending therethrough. A flexible shaft tip portion with a metallic coil spring having a polymeric coating is located on the distal end, with the metallic coil spring being fused to the second end of the main shaft. The polymeric coating has an inner portion configured to define a plurality of lumens which extend through the coil spring. The lumens through the coil spring are aligned with the lumens in the main shaft so that they extend continuously through the catheter. The metallic coil spring is fully encapsulated by the polymeric coating and the second end of the main shaft to which it is fused. A first control wire is located in one of the lumens and affixed to the distal end.
