| 20110282288 | METHOD OF FORMING REINFORCED TUBING - A method of forming a reinforced tubular medical device in a continuous operation, and a medical device formed by the continuous method. An elongated core capable of movement about a line is provided. An elongated tubular member is formed around a moving length of the core by extruding a coating of a functionalized polymer around the moving core length, applying a reinforcing member to an outer surface of the functionalized polymer coating along the moving length, and extruding a polymeric outer jacket over the functionalized polymer and reinforcing member along the moving length, such that a bond is formed between the functionalized polymer and the polymeric outer jacket. The elongated tubular member is cut to desired length to form the tubular medical device, and the core is removed from the device. | 11-17-2011 |
| 20110213303 | Reinforced Catheter Or Sheath With Reduced Friction Surface - A reinforced catheter or sheath includes an inner tube manufactured via an extrusion process from a mixture of thermoplastic and hollow glass beads. The resultant tube exhibits an inner goose bump surface that defines a central lumen. A reinforcement, such as a braid and/or coil is attached to at least a segment of the outer surface of the inner tube. A second tube of thermoplastic is extruded over at least a portion of the reinforcement. The inner goose bump surface exhibits a net low coefficient of friction comparable to that of polytetrafluoroethylene (PTFE). | 09-01-2011 |
| 20110125133 | Catheter Components and Assembly - A catheter assembly is provided with a stress relief collar for relieving stress due to differences in rigidities of a catheter and coupled fitting. The stress relief collar is provided with an integral clip of the same or a similar soft material. The catheter can be coiled and held in the clip, the flexibility of the latter making it easy to fit and remove coils therefrom with little risk of damage to the catheter. | 05-26-2011 |
| 20110125088 | Apparatus for an improved high pressure medicinal dispenser - An apparatus for an improved high pressure medicinal dispenser is disclosed. The high pressure dispenser may include a handle ( | 05-26-2011 |
| 20110009848 | FLUID INJECTION DEVICE - A medical device is provided. The device includes a cannula with a lumen defined therethrough and an upper portion, a right side portion, a bottom portion, and a left side portion each substantially equally spaced from their respective neighboring portion around the circumferential surface of the cannula. The cannula additionally includes a plurality of apertures disposed through the distal end portion to provide communication from the lumen and a visually perceptible indicator that is configured to allow the cannula to be positioned at an appropriate rotational position within the patient. A plurality of injection needles are disposed within the lumen and a first handle is fixed with respect to the cannula and a second handle is disposed in conjunction with the first handle and fixed to the proximal portion of each of the plurality of needles, the first handle is translatable with respect to the second handle to translate the plurality of needles from a first position where the distal portions of each of the plurality of needles are disposed within the lumen of the cannula, and a second position where the distal portion of each of the plurality of needles extends out of the lumen through their respective aperture. | 01-13-2011 |
| 20090171323 | Catheter assembly and fluid supply apparatus therefor - A catheter assembly includes a multi-lumen catheter and fluid supply apparatus for supplying fluid to said multi-lumen catheter. The fluid supply apparatus includes an inlet element for coupling to a supply of catheter fluid, a plurality of fluid outlet elements arranged to be each coupled to a respective lumen of the catheter and a flow splitter arranged between the inlet element and the outlet elements. The flow splitter is able to split or divert flow of fluid from the inlet to at least one of the plurality of outlets. For this purpose, the preferred embodiment includes a gate for directing fluid flow to one or more of the outlet elements. There may also be provided a diffuser and a nozzle. | 07-02-2009 |
| 20090171318 | Catheter with non-uniform wall thickness - A catheter having a non uniform wall thickness comprising first and second wall regions is described. The first region is thicker than the second region and at least a part of the first region comprises a material having a lower stiffness modulus than the second region. Typically, the ratio of stiffness between the first region and the second region is less than 1.25:1 and preferably approximately 1:1. The first region may comprise the same material as the second region but having a different formulation so that the stiffness modulus is altered. Alternatively, the regions may comprise different materials. The lower modulus material is coextruded into at least a part of the broadest/thicker cross sectional region(s). | 07-02-2009 |
| 20090162585 | JEJUNAL FEEDING TUBE - The present invention provides a method of manufacturing a flexible tube. The method includes the steps of providing a source of material to be extruded and forming a tubular member with an extrusion die. The extrusion die includes a radially and outwardly extending tooth configured to define a protrusion upon the outer surface of the tubular member. The method further includes the step of rotating the tubular member after exiting the extrusion die such that the protrusion forms a helical profile along the length of the tubular member. | 06-25-2009 |
| 20090139614 | METHOD OF CHARACTERIZING PHASE TRANSFORMATIONS IN SHAPE MEMORY MATERIALS - A method of characterizing phase transformations of a shape memory material specimen entails recording data from the specimen during heating and cooling. The temperature of the specimen is changed in a first direction to a first temperature sufficient to define a first inflection and a second inflection in the data being recorded. The temperature of the specimen is changed in a second direction to a second temperature sufficient to define a third inflection in the data. The third inflection is formed by overlapping primary and secondary sub-inflections. The temperature of the specimen is changed in the first direction to a third temperature sufficient to define the first inflection but not sufficient to define the second inflection. The temperature of the specimen is then changed in the second direction to a fourth temperature sufficient to define the secondary sub-inflection in the data being recorded. | 06-04-2009 |
| 20080312640 | Modified luer fittings for feeding tube adapter - A method and apparatus provide a luer fitting connector/adapter that acts as a modified-to-standard size converter piece. The adapter may complete a fluid tight medical system. The adapter may have one end having at least one non-standard sized luer fitting dimension. The non-standard end of the adapter may sealingly interconnect with a luer fitting member having a corresponding non-standard sized dimension. As a result, the adapter and luer fitting member may be directly interconnected with one another while remaining incompatible with standard sized luer fittings. Using the adapter may facilitate preventing the inadvertent direct interconnection of standard sized luer fitting members intended for different purposes, such as the delivery of a feed paste or a medication to a desired location within a patient. The adapter may be directly or indirectly interconnected with a syringe nozzle to facilitate flushing the medical system or a portion thereof. | 12-18-2008 |
