A method of manufacturing a safety catheter includes providing a catheter having a catheter body comprising an exterior surface, a drainage lumen, and an inflation lumen, forming a balloon inflation port between the exterior surface and the inflation lumen, forming a deflation port between the exterior surface and one of the inflation and drainage lumens, fixing a balloon sleeve to the exterior surface over at least the balloon inflation port to define a fluid-tight balloon interior between an interior surface of the balloon sleeve and at least a portion of the exterior surface, removably inserting a deflation plug in the deflation port to water-tightly seal the deflation port until the deflation plug is removed, connecting a proximal portion of a deflation connector to an inside surface of one of the lumens, and connecting a distal portion of the deflation connector to the deflation plug.

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.

A safety balloon catheter includes a flexible, multi-lumen balloon catheter and a hollow barbell-shaped stretch valve. The balloon catheter has a proximal catheter end, a balloon defining a balloon interior to be inflated with an inflation fluid, a hollow inflation lumen extending through the catheter to the balloon interior and shaped to convey the inflation fluid to and from the balloon interior, and a hollow second lumen parallel to the inflation lumen; and a balloon drainage port fluidically connecting the balloon interior to the second lumen. The stretch valve is shaped to permit a fluid to pass therethrough and positioned in the second lumen to at least partially slide therein such that, in a steady state, a distal barbell end of the stretch valve prevents the inflation fluid from passing through the drainage port and, in an actuated state, the distal barbell end slides within the second lumen to permit the inflation fluid to pass through the drainage port and into the second lumen.

A safety catheter includes a flexible, multi-lumen shaft having an outer diameter, a distal tip, a proximal catheter end with a drain end and a proximal inflation end. The multi-lumen shaft defines a drain lumen, a distal hollow balloon portion, at least one inflation lumen, and a drainage port. A hollow stretch valve is coaxially disposed in the drainage lumen, has a fixed portion within the drainage lumen just proximal of an increased stretching portion, and prevents fluid from passing through the drainage port in a steady state. The stretch valve has a sliding portion slidably disposed within the drainage lumen such that, in a stretched state when the proximal catheter end is stretched, the sliding portion slides within the drainage lumen to permit fluid to pass through the balloon drainage port and/or inner wall of the catheter.
