  • Publication number: 20140276663
    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.

  • Patent number: 8801699
    Abstract: To perform a prostatectomy, a directionally illuminating balloon catheter enters a bladder. The catheter has a multi-lumen shaft. The balloon defines an interior fluidically connected to a balloon inflation lumen and is inflated therethrough. The balloon comprises a light source, a light-radiating surface adjacent the shaft-balloon junction, and a substantially opaque surface disposed at a portion of the balloon other than the light-radiating surface such that the integrated light source illuminates a proximal half of the environment outside the balloon. The balloon is inflated while in the bladder. Light from the light source is directed out through the light-radiating surface to illuminate at least a portion of a procedure area at the bladder-prostate junction. With the light illuminating the portion of the procedure area, at least a portion of a prostatectomy is performed at the portion of the procedure area.

  • Patent number: 8591497
    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.

  • Publication number: 20130103005
    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.

  • Patent number: 8382708
    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.
