摘要： An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that extends over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. A bladder plug configured on the distal end of the inner catheter may form a seal between the catheter sheath and the inner catheter. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.

摘要： The present invention provides a catheter site insertion plug composed of a body that includes an upper surface, a lower surface and a protruding portion extending from the lower surface. The protruding portion of the body forms a frustum having a terminus and defines a passageway extending from an opening at the upper surface to an exit orifice at the terminus of the frustum. The passageway is configured to receive a catheter therethrough. The lower surface may include a second protruding portion in the form of an annular ring around the first protruding portion. The first protruding portion may include an end section that extends radially outward to provide an inflection point generally adjacent the terminus of the frustum. The end section may extend outward to provide at least one radial edge. The present invention also provides a catheter system composed of a flexible catheter and catheter site insertion plug.

摘要： A safety balloon catheter includes a catheter having a stretch valve, a connector, a balloon inflated with an inflation fluid, a hollow inflation lumen extending through the catheter to the balloon and conveying inflation fluid thereto and therefrom, a hollow second lumen, and a balloon drainage port fluidically connecting the balloon to the second lumen. The stretch valve has a hollow base fixed in the second lumen at a proximal catheter end and shaped to permit a fluid therethrough and a hollow plug slidably positioned in the second lumen at a given distance from the base to, in a steady state, prevent inflation fluid from passing through the drainage port and, when actuated, slide within the second lumen to permit inflation fluid to pass through the drainage port and into the second lumen. The connector connects the base and the plug and has a length greater than the given distance.

摘要： Methods of modifying the luminal profile of a body vessel are described. An example method comprises advancing a cannula out of the distal end of a catheter disposed within the lumen of a body vessel of an animal and toward a target site on the wall of the body vessel; passing contrast dye through the cannula toward the target site; simultaneously continuing the advancing and passing until the distal end of the cannula punctures the inner layer of the wall of the body vessel at the target site; and passing a bulking agent through the cannula and into a space between connective tissue layers surrounding the vessel wall at the target site. Medical devices, medical device assemblies, and kits are also described.

摘要： A lead delivery apparatus and a method of delivering a medical lead to an anatomic target site. The method includes inserting a hydraulic plug into an internal delivery lumen of a delivery shaft, and coupling a medical lead to the hydraulic plug. Hydraulic pressure is applied to the hydraulic plug through the delivery lumen, thereby moving the hydraulic plug toward an anatomic target site, and advancing the medical lead toward the target site.

摘要： An anti-clogging catheter includes a hollow cannula defining a first interior diameter and a distal end defining a second interior diameter smaller than the first interior diameter. A solid stylet is movable within the fluid passageway and has an outer diameter substantially equal to the second interior diameter of the cannula, the stylet and cannula together defining (1) a closed fluid pathway that prevents neurological material from passing into the distal end of the cannula when the distal end of the stylet is extended into the distal end of the cannula and (2) an open fluid pathway that allows fluid to flow in a single contiguous path around the distal end of the stylet and out of the distal end of the cannula when the distal end of the stylet is retracted away from the distal end of the cannula and remains within the body of the cannula.

摘要： A urinary catheter system includes a catheter, a sheath, an enclosure and a plug. The catheter has distal and proximal ends. The sheath is slidable along the catheter between first and second positions. The enclosure encloses a majority of the catheter and includes a bottom member, a top member, an outer peripheral wall defining an outer hole to allow advancement of the distal end, and an inner peripheral wall defining an inner hole, where the catheter is extendable through the inner hole. Rotating the top or bottom member relative to the other member causes the catheter to wind within the enclosure. The plug can seal the proximal end to block liquid flow, and a user can disengage the plug to allow liquid flow.
