摘要： A pressure activated valve comprises a valve housing defining a lumen for receiving bodily fluids therein and a flexible membrane disposed in the valve housing. The flexible membrane includes a slit extending therethrough so that the flexible membrane may be moved between an open and a closed configuration based on fluid pressure within the lumen. A nonthrombogenic coating may be formed on fluid contacting surfaces of the flexible membrane.

摘要： A pressure actuated valve for controlling the flow of fluid through a medical device, the valve comprises a housing including a lumen extending therethrough and a flow control membrane extending across the lumen to control the flow of fluid through the lumen. The membrane includes a plurality of slits extending therethrough so that, when the membrane is acted upon by a pressure of at least a threshold magnitude, the slits open to permit flow through the lumen and, when not acted upon by a pressure of at least the predetermined magnitude, the slits are maintained closed by a biasing force applied thereto by the membrane to prevent flow through the lumen. Each of the slits extends between end portions thereof along a curve wherein a distance between a first end portion of a first one of the slits and a first end portion of a second one of the slits is a minimum distance between the first and second slits.

摘要： An improved valve port system provides blood access in a patient through a subcutaneous fluid flow conduit during a dialysis procedure. The system includes several elements, including a engagement member defined by a tubular body having a proximal end, a distal end and a tubular lumen therebetween. The distal end has a tapered bevel defined thereat and a tapered protrusion proximate thereto defined upon an exterior surface of the tubular body. In addition, the system provides a dialysis port member having a housing with a generally cylindrical valve rotatably positioned therein. The valve includes an open end, a closed end and an orifice near the closed end. The valve further includes a longitudinal groove defined along an interior surface thereof. The groove, which is capable of being in registry with the protrusion, is coincident with the protrusion so as to intussuscept the protrusion therein. In this manner, rotation of the engagement member effects rotation of the valve between an open position wherein the orifice is in fluid communication with the fluid flow conduit and a closed position wherein fluid communication between the orifice and the conduit is precluded.

摘要： An implantable port includes a bottom portion having a needle-penetrable region running continuously along a majority of a perimeter of the implantable port. A method for customized suturing of an implantable port also includes creating a port pocket, and advancing a suture needle through the needle-penetrable region. The needle-penetrable region could be a self-sealing elastomer, such as silicone. The method could include the step of determining suture locations after the port pocket is created.
