Assignee:

Mayser, LLC - Fort Lauderdale FL

International Classification:

A61M 29/00
A61M 27/00

US Classification:

60410101, 604915, 604921, 604544

Abstract:

A safety catheter includes a multi-lumen shaft. The shaft has a proximal shaft portion with a distal end having a given outer diameter and a distal tip portion having an outer diameter less than the given outer diameter. A hollow balloon is disposed at a junction of the proximal shaft portion and the distal tip portion. The balloon has a distal leg fixedly secured to the distal tip portion and a proximal leg removably secured to the proximal shaft portion.

A61M 27/00

US Classification:

604544, 60410306, 604920

Abstract:

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 inflation or drainage lumen, or both, has a fixed portion within the inflation or drainage lumen, or both, and prevents fluid from passing through the drainage port in a steady state and has a sliding portion slidably disposed within the inflation or drainage lumen, or both, such that, in a stretched state when the proximal catheter end is stretched, the sliding portion slides within the inflation or drainage lumen, or both to permit fluid to pass through the balloon drainage port and/or wall of the catheter.

MAYSER, LLC - Fort Lauderdale FL

International Classification:

A61M 25/00

US Classification:

604544

Abstract:

A safety catheter includes a shaft. The shaft has a proximal shaft portion having a proximal end, a distal tip portion defining a junction with the proximal shaft portion, a fluid drain lumen, and a balloon inflation lumen. The fluid drain lumen defines a distal fluid drain opening at the distal tip portion distal of the junction and a proximal fluid drain opening adjacent the proximal end and fluidically connected to the distal fluid drain opening. A hollow zero-pressure balloon is disposed at the junction and has an interior fluidly connected to the balloon inflation lumen, a distal leg fixedly secured to the distal tip portion, and a proximal leg temporarily secured to the proximal shaft portion.

International Classification:

A61M 25/10
A61M 25/00

Abstract:

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.

Abstract:

A safety catheter for draining a given fluid includes a hollow stretch valve and a flexible, multi-lumen, balloon drainage catheter having a proximal catheter end, a balloon defining a balloon interior to be inflated with an inflation fluid, a drain lumen. and a balloon drainage port fluidically connecting the balloon interior to the drain lumen. The hollow stretch valve is shaped to permit the given fluid to pass therethrough and is positioned in the drain lumen to at least partially slide therein such that, in a steady state, the stretch valve prevents the inflation fluid from passing through the drainage port, and, in a stretched state when the proximal catheter end is stretched, the distal sliding portion slides within the drain lumen to permit the inflation fluid to pass through the drainage port and into the drain lumen.

International Classification:

US Classification:

604 9902, 604544

Abstract:

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.
