A urinary catheter assembly includes a urinary catheter sealed inside of a closed package. The urinary catheter has a first closure sealing a proximal opening and including a first extension portion that is coupled to the closed package, and a second closure sealing a distal opening and including a second extension portion coupled to the closed package.

Catheters and methods for controlling bleeding in airways and for occlusion of airways are provided that allow a bronchoscope to be withdrawn from the airway while an inflated balloon catheter remains in position in the airway, for example at a site of airway bleeding.

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.

One embodiment provides a balloon catheter which has an inner tube having a main lumen and an outer tube which forms an expansion lumen. A part of the inner tube is connected to the outer tube at a position closer to the proximal end than a balloon, a side hole is open at the connection section, and a weak section is provided to the inner tube a position closer to the distal end than the side hole. The weak section has lower rigidity than the remaining portion of the inner tube. When the balloon is expanded by fluid supplied to the expansion lumen, the weak section is pressed by the fluid pressure to thereby close the main lumen of the inner tube.

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.

A catheter system may include a catheter assembly, a fluid storage unit, and fluid. The catheter assembly may include a catheter hub, a catheter, an extension tube, and an adapter. The catheter hub may include a distal end, a proximal end, a lumen extending between the distal end and the proximal end, and a side port. The catheter may extend distally from the distal end of the catheter hub. A distal end of the extension tube may be coupled to the side port. The adapter may be coupled to a proximal end of the extension tube. The fluid storage unit may be coupled to the adapter and may include a reservoir, a barrier, and an actuator. The fluid may be disposed within the reservoir. In response to breach of the barrier by the actuator, the reservoir may be in fluid communication with the lumen of the catheter hub.

The present invention provides for a safety device and methods of using a safety device for use with a medical implement having a body with an inlet end portion, the safety device comprises a bracket for mounting on the body of the medical implement; a cap supported by the bracket and sized to fit over and seal the inlet end portion of the medical implement in a safety position wherein the cap covers the medical implement; an elongate shaft having a longitudinal axis, the shaft being secured to the cap and being slidably and pivotally supported by the bracket so that the cap can be raised away from the inlet end portion of the medical implement and be pivoted about the longitudinal axis of the shaft away from the inlet end portion; and a biasing means for biasing the cap to the safety position.

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.

A smart obturator assembly includes a hub forming a central passage. The hub is configured to couple to a proximal end of a device that forms a lumen such that the central passage is in fluid communication with the lumen. A collar on the hub includes electronic circuitry in signal communication with remote reception circuitry. An obturator is movably positionable within the lumen. The obturator is movable within the lumen between a first position and a second position. The obturator includes a distal end and a sensor at the distal end. The sensor is configured to sense an environmental characteristic within a patient's blood stream, generate a signal representative of the environmental characteristic, and transmit the signal to the electronic circuitry. The electronic circuitry is configured to receive the signal and transmit the signal to the remote reception circuitry.

An obturator assembly includes an obturator at least partially positionable within a lumen of a device. The obturator has a distal end with a tip portion and an opposing proximal end. A sensor assembly is at the tip portion. The sensor assembly is configured to sense one or more environmental characteristics and to generate one or more signals representative of the one or more environmental characteristics. A hub is operatively coupled to the obturator. The hub is also operatively coupled to electronic circuitry that is coupled in signal communication with the sensor assembly. In certain embodiments, the electronic circuitry is configured to receive the one or more signals from the sensor assembly and transmit the one or more signals to remote reception circuitry and/or display a datum representative of the one or more environmental characteristics on a display of the hub.
