A valve assembly includes a housing defining an aperture, a passageway, and a branch passage. The branch passage extends from the aperture and intersects and communicates with the passageway. The branch passage is disposed at an angle greater than 90 degrees with respect to the passageway. A piston is disposed at least partially within the branch passage and is movable from a first position to a second position. The piston allows communication between the passageway and the aperture when the piston is in the first position, and the piston blocks communication between the passageway and the aperture when the piston is in the second position. An angled seal may be positioned around the piston.

A sleeve is provided for placing over a flexible endoscope. The sleeve has a port between its distal and proximal openings and the port is connected to a vacuum source. Once the endoscope is retracted proximal to the suction port, the sleeves proximal opening is sealed off and the entire sleeve is turned into a suction lumen. Devices and methods in accordance with the invention provide improvement in removing materials from body cavities, especially in removing stones from the upper urinary tract.

A needle guiding apparatus includes a base, a guide assembly, and an imaging sight. The base defines an opening that extends through the base. The guide assembly includes at least one passage, and the guide assembly is disposed within the opening of the base. The guide assembly also is rotatable about at least one axis. The imaging sight is disposed adjacent the passage. An entry needle can be inserted through the needle guiding apparatus and into a body. Devices and methods according to the present invention allow a medical professional to accurately and rapidly place a probe, such as a needle, in a patient.

A ureteral stent comprising an elongated tubular member having a body portion and opposed distal end portion and proximal end portion, the elongated tubular member defining a lumen therein; a retention disk comprising a plurality of generally axial, spaced-apart collapsable struts interconnected with a membrane to form a generalized tube with a retention disk lumen therein, the retention disk lumen in fluid communication with the lumen of the body portion, the struts and the membrane couple to the body portion proximal end at a retention disk distal end and terminate at a retention disk proximal end, each strut having a widthwise folding hinge substantially dividing the length of the strut, the struts adapted to have an expanded state wherein the struts are unfolded and substantially straight, as well as a free-resting state wherein each strut folds in upon itself at the folding hinge to form an inverted umbrella-like disk-shaped configuration; and a valve, wherein the inverted umbrella-like configuration provides a conformal shape to the ureteral orifice.

In accordance with the invention, there are provided medical devices for providing a fluid passage between two areas in the body. An embodiment of the present invention relates to a stent comprising a tubular member comprising a distal transition region and a proximal transition region adapted to provide the ability for the stent to accommodate the dynamic urinary tract anatomy that stretches and relaxes. The distal transition region and the proximal transition region is adapted to exhibit a physical property that provides both longitudinal elasticity, allowing for stretch and recoil, as well as radial elasticity, allowing for bending and recovery.

A ureteral access sheath having nonuniform axial-stiffness adapted for proximal pushability needed for placement while also having distal flexibility to minimize trauma to the body lumen and ureter. Embodiments in accordance with the present invention provide a nonuniform axial-stiffness ureteral access sheath comprising a nonuniform axial-stiffness jacket encapsulating the reinforcement layer with the inner liner. Other embodiments in accordance with the present invention provide a nonuniform axial-stiffness ureteral access sheath comprising a nonuniform axial-stiffness reinforcement layer encapsulated between a single axial-stiffness jacket and the inner liner. Other embodiments in accordance with the present invention provide a nonuniform axial-stiffness ureteral access sheath comprising a nonuniform axial-stiffness jacket encapsulating a nonuniform axial-stiffness reinforcement layer with the inner liner.

A medical instrument comprising a flexible, filamentous shaft slideably disposed in a sheath, the instrument including an electronic imaging system comprising an image sensor carried on a distal end portion of the instrument. The shaft may be used as a guidewire for a complementary guided device, or it may be used to carry a functional element for performing a procedure at a target site in a patient's body. In other embodiments, the present invention contemplates a flexible sheath, preferably having a simple tubular construction, with an electronic imaging system at its distal end. The sheath is adapted to slideably receive a shaft, preferably a filamentous shaft, that closely fits the sheath. The shaft carries functional element at its distal end. The instruments according to the present invention may include one or more filaments along their length for deflecting an insertable portion of the instrument.
