摘要： A relatively flexible, dual-lumen enteral feeding tube (10) for delivery of fluid through a patient's esophagus to the patient's intestinal tract is provided having an enteral feeding lumen (22) and a relatively small stylet lumen (24) separate from the enteral feeding lumen (22) and longitudinally co-extensive with a substantial length of the enteral feeding lumen (22). The stylet lumen (24) has a removable relatively stiff metal stylet (85), the stylet (85) with a tapered annealed distal portion. The stylet (85) has a coating of polytetrafluorethylene and a coating of silicone over the polytetrafluorethylene. The tube (10) also has a Y-site adaptor (16) fixed on the proximal end of the tube (10). The Y-site adaptor (16) has Y-site openings through which access may be had to the enteral feeding lumen (22).

摘要： A catheter (10) and a method of manufacture thereof which includes a relatively rigid body (11) and a relatively soft tip (12) for decreasing the likelihood of injury or damage to tissue such as the wall of a blood vessel or the heart when the catheter (10) is used as a part of an invasive medical procedure such as angiography or angioplasty. The method includes the use of a core (15) which is sufficiently resistant to high temperatures to allow extrusion of polymeric material thereover in the process of forming the catheter (10). The core (15) controls the catheter's (10) inside diameter, and is sufficiently heat resistant to allow its use through all subsequent manufacturing process steps involving the formation of the soft tip (12). The method of the present invention prevents foreign material build up within the inner diameter of the catheter (10) during processing, eliminates the need for special fusion support mandrels during fusion of the soft tip (12) onto the catheter body (11), and maintains the integrity of the internal diameter of the catheter body (11) and soft tip (12) during the thermal and pressure processes of the manufacture. The invention also includes a novel method of sizing and fusing the soft tip (12) onto the catheter body (11) including the use of a piston member (29) about the core (15) which can apply pressure to the material forming the soft tip (12) at any time before, during or after the thermal heating step.

摘要： Un tube d'alimentation entérale relativement flexible et à double orifice (10) pour l'apport d'un fluide au travers de l'oesophage d'un patient jusqu'au conduit intestinal du patient possède un orifice d'alimentation entérale (22) et un orifice (24) de stylet relativement petit séparé de l'orifice (22) d'alimentation entérale et s'étendant dans le même plan et sur une certaine longueur que l'orifice d'alimentation entérale (22). L'orifice pour stylet (24) possède un stylet métallique amovible relativement rigide (85) présentant une partie distale conique recuite. Le stylet (85) possède un revêtement en polytétrafluoroéthylène et un revêtement de silicone sur le polytétrafluoroéthylène. Le tube (10) possède également un adaptateur de site en Y (16) fixé sur l'extrémité proximale du tube (10). L'adaptateur en Y (16) possède des ouvertures en Y permettant l'accès à l'orifice d'alimentation entérale (22).
