摘要： A catheter with valve for implantation in a vascular structure of a living being. The catheter is in the general shape of a "T" with the top of the "T" implanted within the lumen of a vascular structure, and the leg of the "T" extending out of the vascular structure through an incision in the vascular structure. The lumen of the implanted portion of the catheter completely occupies the lumen of the vascular structure, causing all blood flow through the vascular structure to be directed through the implanted portion of the catheter. A valve is placed in the wall of the implanted portion of the catheter which opens into the lumen of the leg of the "T" of the catheter upon application of sufficient differential pressure between the lumens of the two portions of the catheter. The leg of the "T" is connected to the side wall of the implant portion of the catheter at an angle, such that the axis of the lumen of the leg of the "T" intersects the axis of the lumen of the implanted portion of the catheter at approximately a 45 degree angle.

摘要： Improved elastomeric materials useful for medical and therapeutic device applications, such as penetrable septa, are described. In one aspect, the materials are deeply cleaned with solvent to significantly lower levels of undesirable organics. In another aspect, internally lubricated elastomer compositions compatible for use in medical and therapeutic device applications are provided. The lubricating fluid is present in the composition from about 0.5% to 50% by weight, and is initially substantially homogeneously dispersed in the elastomer. The fluid can be integrated into the elastomer by a solvent infusion method. In another aspect an internally lubricated thermoplastic septum, having an appropriate hardness for resealability with multiple penetrations, is provided.

摘要： A medical system for transferring fluids (e.g. blood) to or from patients which includes a needle having a proximal end, a distal end attached to a syringe (or other comparable fluid transfer device), a medial section, and an internal passageway. The medial section is elliptical in cross-section with dual arcuate side walls. The proximal end is blunt and rounded. Also included is an access site having a conduit with a resilient tubular port extending outwardly therefrom. The port includes a bore therethrough. The port and the bore are both elliptical in cross-section. A resilient compression member having an elliptical opening therein is positioned on the port to exert pressure thereon and close the bore. In use, the needle is urged into the bore, temporarily deforming the compression member. After removing or delivering fluids using the syringe (or other device), the needle is withdrawn from the bore which is self-sealing by the compressive action of the compression member.

摘要： The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. A coupling device includes multiple male and female connectors that are joined to a common line. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are property joined. If any of the connectors is not property mated to a corresponding one, the coupling will leak. The coupling devices are made unique by providing an arrangement the connectors, number of connectors, shape of connectors or arrangement of interfering connector parts that ensure that any attempt to improperly couple two fluid lines will result in the incomplete mating of one or more of the connectors and thereby cause leakage of the fluid, failure of the coupling to engage, or otherwise cause the attempt to connect to fail.

摘要： One of the most significant safety concerns in the automation of extracorporeal blood treatments such as dialysis is the risk of blood leakage. Extracorporeal blood treatment systems draw blood at such a high rate that a loss of integrity in the blood circuit can be serious. There are a number of mechanisms for detecting and preventing leaks, but none is perfect. This tends to limit the use of such equipment in unsupervised settings, such as the home will be limited. Some leak detection schemes can be made sensitive enough to detect the barest of leaks, but when this is done, they result in too many false positives. The invention combines information from multiple inputs to enhance sensitivity in leak detection and reduce the problem of false positives.

摘要： A bandage can be used to secure a needle to an access site so as to prevent unintended movement or withdrawal of the needle from the access site during administration of a treatment to a patient. After treatment, the needle can be removed by manipulating a portion of the bandage. Another portion of the bandage can be maintained in position over the access site during needle removal and can be used to promote clotting of the site after needle removal. The bandage may include a clotting agent, a hemostasis pad, and/or a clot-promoting structure. Additionally or alternatively, finger pressure can be applied to the access site through the bandage. For example, the bandage may include a viewing window without any adhesive to allow visual monitoring of the access site during treatment. Finger pressure may be applied to the viewing window and thereby to the access site during and after needle removal to encourage hemostasis.
摘要翻译： 可以使用绷带将针固定到进入位置，以便在给予患者的治疗期间防止针头从进入位置的意外移动或撤回。 治疗后，可以通过操纵绷带的一部分去除针头。 绷带的另一部分可以在针移除期间保持在进入位置上的适当位置，并且可以用于在针移除之后促进部位的凝血。 绷带可以包括凝血剂，止血垫和/或促凝结构。 另外或替代地，手指压力可以通过绷带施加到进入部位。 例如，绷带可以包括没有任何粘合剂的观察窗，以允许在治疗期间对进入部位的视觉监测。 可以将手指压力施加到观察窗，从而在针移除期间和之后到达进入部位以促进止血。

摘要翻译： 体外血液治疗如透析自动化中最重要的安全问题之一是出现血液渗漏的风险。 体外血液处理系统以如此高的速度吸取血液，使得血液回路的完整性丧失可能严重。 有一些检测和防止泄漏的机制，但没有一个是完美的。 这样会限制在无监督设置中使用这种设备，例如家庭将受到限制。 一些泄漏检测方案可以做得足够灵敏，可以检测最多的泄漏，但是当这样做时，它们会产生太多的假阳性。 本发明组合来自多个输入的信息，以提高泄漏检测的灵敏度，并减少误报的问题。

摘要： A sharp medical device is attached to a flexible element by a base of the sharp device. The base has a portion with a score line defining a position of predictable failure such that the base can be broken by applying a breaking moment at the score line to permit a user to separate the sharp device and the flexible element cleanly at the position of predictable failure. Various other embodiments are included, which disclose a similar effect.
