Balloon-manipulating devices, balloon catheter assemblies, and methods thereof

A balloon catheter assembly, comprising:

• a balloon catheter including:
• one or more primary drainage apertures in a distal end portion of a shaft of the balloon catheter;
• one or more secondary drainage apertures in the distal end portion of the shaft, the one or more secondary drainage apertures closer to a proximal end portion of the shaft than the one or more primary drainage apertures;
• and
• a balloon coupled to the shaft between the one or more primary drainage apertures and the one or more secondary drainage apertures, the balloon fluidly coupled to an inflation lumen extending through a length of the shaft configured for inflating the balloon;
• and
• a balloon-manipulating device, including:
• a tubular body disposed over the balloon, the tubular body including a proximal end portion adjacent the one or more primary drainage apertures and a distal end portion adjacent the one or more secondary drainage apertures;
• one or more balloon-compressing pieces of a sidewall of the tubular body, each balloon-compressing piece configured for compressing a different portion of the balloon when the balloon is in an inflated state;
• and
• one or more balloon-letting through holes through the sidewall of the tubular body, each balloon-letting through hole configured for allowing therethrough a different portion of the balloon when the balloon is in the inflated state.

A balloon catheter assembly, comprising:

• a balloon catheter, including:
• one or two primary drainage apertures in a distal end portion of a shaft of the balloon catheter;
• one or two secondary drainage apertures in the distal end portion of the shaft, the one or two secondary drainage apertures closer to a proximal end portion of the shaft than the one or two primary drainage apertures;
• and
• a balloon coupled to the shaft between the one or two primary and secondary drainage apertures, the balloon fluidly coupled to an inflation lumen extending through a length of the shaft configured for inflating the balloon;
• and
• a balloon-manipulating sleeve, including:
• a tubular body disposed over the balloon, the tubular body including a proximal end portion adjacent the one or two primary drainage apertures and a distal end portion adjacent the one or two secondary drainage apertures;
• one or two balloon-compressing pieces of a sidewall of the tubular body, each balloon-compressing piece configured for compressing a different portion of the balloon to form a corresponding channel when the balloon is in an inflated state;
• and
• one or two balloon-letting through holes through the sidewall of the tubular body, each balloon-letting through hole configured for allowing therethrough a different portion of the balloon to form a corresponding balloon lobe when the balloon is in the inflated state, wherein one or two balloon lobes are configured to anchor the balloon catheter assembly in a bladder of a patient, and one or two channels are configured to transport residual urine from the bladder, through a bladder neck, through a portion of a urethra, and to the one or two secondary drainage apertures for drainage of the residual urine while the balloon catheter assembly is anchored in the bladder of the patient by the one or two balloon lobes.
