摘要： 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.

摘要： 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.
摘要翻译：一种方法和装置提供鲁尔接头连接器/适配器，其用作改进的标准尺寸转换器片。适配器可以完成流体密封的医疗系统。适配器可以具有至少一个非标准大小的鲁尔配件尺寸的一端。适配器的非标准端可以与具有对应的非标准尺寸尺寸的路厄配件部件密封地互连。结果，适配器和鲁尔配件可以彼此直接互连，同时与标准尺寸的路厄配件保持不相容性。使用适配器可以有助于防止意图用于不同目的的标准尺寸鲁尔接头构件的无意直接互连，例如将饲料糊或药物递送到患者内的期望位置。适配器可以直接或间接地与注射器喷嘴互连，以便于冲洗医疗系统或其一部分。

摘要： A surgical cutter with a flat blade and a cutting wedge allows a surgeon to safely trim a foreign object inside a body, such as a urethral sling inside a patient, so that a minimum of sling remains in place after cutting. The shortened sling minimizes tension applied to the urethra and to any nearby bladder tissues. The cutter may also be used to trim other prostheses or devices implanted within a patient. The cutter is configured so that the cutting surface of the blade does not contact tissue of the patient.

摘要： A medical device (10) includes a catheter shaft (11) including inner and outer catheter shafts (12 and 14), and an expandable balloon (18) carried by the catheter shaft (11). The balloon (18) is made from an irradiation cross-linked mixture of a polyamide elastomer and at least one additional cross-linking reactant. The polyamide elastomer can be a polyester amide, a polyether ester amide or a polyether amide, and is preferably a nylon block copolymer. The cross-linking reactant can be: (a) a difunctional material, (b) a trifunctional material, (c) a tetrafunctional material, or (d) an aromatic molecule containing at least two ring substituents, each of the ring substituents having labile hydrogens at a benzylic site therein. The cross-linking reactant can also be diallyl phthalate or meta-phenylene dimaleimide. Irradiation is carried out by exposure to an electron beam or to ultraviolet, X- or gamma radiation, preferably at a total fluence of about 0.5 to about 20 megarads. The amount of the cross-linking reactant is selected to avoid the formation of gelling during the process by which the balloon (18) is made, and the amount of the cross-linking agent and the irradiation fluence are selected to give the balloon a strength generally about equal to that which would be obtained by mere irradiation.

摘要： A flexible plastic material catheter having a distal tubular member portion with a greater than 75 weight percent loading of a radiopaque agent for radiographic viewing. The catheter comprises an elongated member having a proximal portion and a distal end portion with a flexible, radiopaque plastic material having a durometer lower than that of the proximal portion. The plastic material of the distal end portion comprises a homogeneous and evenly dispersed composition of a 20 weight percent base thermoplastic, elastomer material such as a polyether block amide and 80 weight percent loading of a radiopaque agent such as tungsten. This distal end portion plastic material exhibits a durometer of approximately 47 on the Shore D scale, whereas the polyether block amide material exhibits a durometer of approximately 40 on the Shore D scale. The flex modulus of the polyether block amide material is in a range of 23,000 to 75,000 pounds per square inch. The proximal end portion comprises a base thermoplastic material such as a polyamide elastomer material and a radiopaque agent of bismuth oxychloride.

摘要： 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).

摘要： The present invention provides apparatus and methods for facilitating folding of a balloon before, during or after a medical procedure. In a first embodiment, the apparatus generally comprises at least one catheter shaft member, a balloon disposed on a distal region of the catheter shaft member, and at least one folding member disposed along at least a proximal region of the balloon. The folding member may comprise at least one radially-outward projecting member integrally formed with or attached to the balloon, or an internally-formed groove in the balloon, which is adapted to promote twisting of the balloon to reduce the profile of the balloon in the deflated state. Optionally, biasing members may be disposed between the folding member and an adjacent portion of the balloon to promote folding of the balloon in a clockwise or counter-clockwise direction.
