    摘要： Vascular access systems for performing hemodialysis are disclosed. The vascular access system contemplates a catheter section adapted for insertion into a vein and a graft section adapted for attachment to an artery. The catheter section may have metal or polymer wall reinforcements that allow the use of thin-walled, small outer diameter conduits for the vascular access system. One or more of the adhered, embedded or bonded conduit reinforcement structures may be removable without significant damage to the conduit sections to facilitate attachment of the sections, or to a connector between the sections. Various self-sealing materials are provided for use in the vascular access system, as well as temporary access sites and flow control/sensor systems.

    摘要： An electrokinetic delivery or diagnostic device for personal use and self-administration of a medicament to a treatment site is provided. The device includes a housing containing a power supply, a first active electrode and a ground tactile electrode. An applicator includes a pad for containing medicament for overlying the first electrode of the device. The medicament may be applied by the user to the pad, contained within the pad or contained in rupturable capsules within the pad, together with a hydrogel if necessary for imparting electrical conductivity whereby, upon application of the applicator to the treatment site, the medicament is electrokinetically transported into the treatment site. In another form, the applicator is self-contained, having a power supply, a first electrode overlying a pad and a ground electrode from the opposite side from the pad whereby the individual presses the pad against the treatment site to complete the electrical circuit and electrokinetically drive the medicament into the treatment site.

    摘要： A urethral valve system includes a fixation balloon that is positioned in and contoured to the geometry of the bladder near the opening to the urethra. The fixation balloon, which is narrower at an end that is closest to the urethra and wider at an opposite end, includes a channel through which urine is directed to flow from the bladder to the urethra. A valve balloon is positioned in the channel and inflates to prevent urine flow through the channel and deflates to allow urine to flow around the balloon and out the end of the channel. The fixation balloon may be attached to a Foley-type catheter, with the catheter providing the channel through the balloon. The fixation balloon then acts as a shock absorber for the system by moving relative to the catheter in response to, for example, a contraction in the bladder. The catheter may contain lumens that provide access to the valve balloon and/or the fixation balloon. The fixation balloon is inserted in a deflated state and inflated to hold the system in place. The fixation balloon remains inflated with the valve balloon providing continence when it is in an inflated state and allowing voiding when it is in a deflated state. Only when the device is to be removed from the body is the fixation balloon deflated.

    摘要： A urethral valve system includes a valve balloon that inflates to provide continence and deflates to allow urine to flow around the balloon and an attached catheter that extends through the urethra, and out of the body through the meatus. The urine cleanses the valve balloon, the catheter and the urethra of bacteria, and thus, minimizes infection. The catheter includes a check valve at the end that is accessible to the user. To inflate the balloon, the user attaches to the check valve a small pump that supplies air or a liquid such as water to inflate the balloon. To deflate the balloon, the user manipulates the check valve to allow the water or air to drain from the balloon. The valve balloon may be positioned in the bladder. To retain the system in the bladder when urine flows around the balloon and the catheter, the balloon deflates to a shape that is wider than the diameter of the neck of the bladder. Alternatively, the system may include an anchoring device, such as rubber fingers that extend from the base of the balloon beyond the neck of the bladder. The valve balloon may also be positioned in the urethra. The system then includes an anchoring device that is positioned in the bladder to hold the valve balloon in its deflated state in the urethra against the flow of urine through the urethra and around the balloon and the attached catheter. The valve system may further include an everting mechanism that provides non-irritating delivery of the valve balloon and/or the anchoring device.

    摘要翻译： 尿道瓣系统包括阀球囊，其充气以提供连续和放气，以允许尿液在气囊周围流动，以及附接的导管，其延伸穿过尿道，并通过口腔从体外流出。 尿液清洗阀球囊，导管和尿道的细菌，从而最大限度地减少感染。 导管包括在使用者可接近的末端的止回阀。 为了使气囊膨胀，使用者将单向阀附接到供应空气或液体如水的小泵来使气囊膨胀。 为了使气囊放气，用户操纵止回阀以允许水或空气从气球中排出。 气囊可以位于膀胱中。 当尿液在气囊和导管周围流动时，将系统保持在膀胱中，气球缩小至比膀胱颈部直径更宽的形状。 或者，系统可以包括锚定装置，例如从球囊的基部延伸超过囊的颈部的橡胶指。 气囊也可以定位在尿道中。 该系统然后包括定位在膀胱中的锚定装置，以将气囊保持在其在尿道中的放气状态，抵抗穿过尿道并且围绕球囊和附接的导管的尿流。 阀系统可以进一步包括提供瓣膜球囊和/或锚定装置的无刺激性输送的转动机构。
