摘要： A catheter (10) including a catheter tube (11) and a bolus tip (20), the bolus (20) having a radially extending main side port (69). In one embodiment the catheter (10) also has second and third side ports (35/37) axially spaced from said main side port (69). The second and third side ports (35/37) are each axially elongated, with an edge which is semi-circular in cross-section. The second side port (35) is displaced 180° from the main side port (69). The third side port (37) is axially aligned with the main port (69). The catheter (10) is thickened in a dimple (45, 47) opposite each of the second and third side ports (35/37). Another catheter embodiment specifically for hemodialysis includes a dual lumen tube (310) with a bolus (351) at its distal end. A multiple venous ports (335/337) are formed in both the arterial and venous lumens wherein the special configuration of these ports is similar to those of the afore-mentioned single lumen catheter. Variations of this embodiment utilize a bolus with a 13.5 French tube connector section and a 10 French nose section.

摘要： An enteral feeding catheter (5) that provides access to both the stomach and the jejunum for feeding, aspiration and decompression. The catheter includes a dual lumen 'D' tube (30) that joins to an external 'Y' connector (25) at the proximal end of the tube. The connector serves both lumens as a source for fluid or aspiration. The gastric lumen (37) and the jejunal lumen (38) of the 'D' tube both connect to a transitional connector bolus in the stomach. The gastric lumen of the 'D' tube joins with a lumen in the transitional bolus that communicates with a gastric port (27). The gastric port is recessed to the level of its full internal lumen, thereby providing maximum protection against occlusion and maximum area for outflow. The 'D' jejunal lumen connects in the bolus with a lumen that transitions from a 'D' shape to a full circle shape. The latter provides for the attachment of a smaller, round, single lumen tube that extends into the jejunum. At the distal end of the jejunal tube is a bolus (11) containing an improved port that is also recessed to the level of the floor of the internal tube lumen to provide maximum protection against occlusion and maximum area for outflow. Both the gastric port in the transitional bolus and the jejunal port in the tip bolus may include a structural arch protruding radially outwardly therefrom. An arch is effective to prevent the body segment of either bolus from bending and restricting the ports. The invention also provides for the insertion of the tube over a guidewire (21) rather than with an internal stylet, as is normally the case with nasally inserted tubes.
摘要翻译： 一个肠道喂养导管（5），提供进入胃和空肠进食，抽吸和减压。 导管包括双腔“D”管（30），其与位于管近端的外部“Y”连接器（25）连接。 连接器可将两个腔作为液体或抽吸源。 'D'管的胃腔（37）和空肠腔（38）都连接到胃中的过渡连接器团。 'D'管的胃腔与过渡团中的腔连接，所述过渡团与胃端口（27）连通。 胃口凹陷至其全内腔的水平面，从而提供最大的防止堵塞和最大流出面积。 'D'空肠腔在推注中与从“D”形转变为完整圆形的腔连接。 后者提供了延伸到空肠中的更小的圆形单腔管的附接。 在空肠管的远端是包含改进端口的大丸剂（11），所述改进端口也凹入到内管腔的底部水平面以提供最大的防止堵塞和最大流出面积。 过渡食团中的胃口和尖端食团中的空肠口都可以包括从其径向向外突出的结构拱。 拱形有效地防止任何一个团块的身体部分弯曲并限制端口。 本发明还提供了将导管插入引导线（21）而不是使用内部探针，如通常鼻插入管的情况那样。

摘要： This invention is an improved catheter and bolus for delivering or suctioning fluids to the body cavity of a patient. The catheter (10) includes a tube with a proximal end for joining it to a source of fluid or suction, and a distal end connected to a bolus (320). The bolus has a tubular shaped body (321) with a tube glue area section (325) at one end, a bullet tip section (327) at the other end, and a flow passage section (326) between the connector and nose sections. The tube glue area section (325) and the flow passage section (326) have an irregularly shaped lower surface. In one aspect of the present invention the irregularly shaped surface forms an arch (328).

摘要： A blood vessel catheter includes a dual lumen catheter tube and a bolus insert attached to the distal end of the tube. First and second ports are formed between the nose section of the bolus and distal end openings of first and second lumens in the tube. The catheter is fabricated by insert molding a thermoplastic bolus onto the distal end of a thermoplastic tube.

摘要： This invention is a corporeal access tube assembly (10) including a tube segment (41) in which a coil spring (42) is embedded along a portion of the segment. A retention balloon (20) is secured to the tube segment around a portion which does not contain the spring coil. The balloon is inflated when in operation but its walls are not stretched to any noticeable extent. The tube segment extends through a split external bolster (21) which opens to permit positioning of the tube segment and closes to clamp the tube segment in place. A gauging system on the tube segment permits precise positioning of the bolster.

摘要： A hemodialysis catheter (10) comprising a dual lumen tube (11) with a bullet nose (57) bolus (20) at its distal end. A venous port (89) is formed in one side of the bolus (20) adjacent the bullet nose (57) of the bolus (20). An arterial port (37) is formed in the bolus (20) circumferentially displaced 180 degrees around the catheter (10) from the venous port (89). The bolus (20) contains a venous passage (59B) which transitions from a smaller diameter D-shaped cross-section to a larger diameter circular cross-section. The bullet nose (57) is thinner than the tube (11) but is inclined on an angle to the axis of the tube so that a portion of its outer periphery is substantially tangent to a hypothetical cylinder containing the trailing edge of the venous port (89).

摘要： A catheter comprising a dual lumen tube with a bolus at its distal end having a bullet nose. A venous port is formed in one side of the bolus adjacent the bullet nose of the bolus. An arterial port is formed in the bolus circumferentially displaced 180° around the catheter from the venous port. The bolus contains a venous passage which transitions from a smaller two-thirds moon shaped cross-section to a larger circular cross-section. The arterial passage has a crescent-moon shaped cross-section. The bullet nose is not as thick as the tube and is inclined on an angle to the axis of the tube so that a portion of its outer periphery is substantially tangent to a hypothetical cylinder containing the trailing edge of the venous port.
