Delivery systems for conformable fillable medical balloons

A method of implanting a conformable, fillable balloon in a body, the method comprising:

• inserting a needle to a target location in the body;
• advancing a dilator over the needle to widen an access path;
• advancing a sheath over the dilator;
• removing the dilator while leaving the sheath in place;
• advancing a balloon delivery system through a lumen of the sheath, with a conformable, fillable balloon in a compressed configuration releasably coupled to the balloon delivery system;
• positioning the balloon at the target location;
• transferring a filler material to an interior cavity of the balloon, causing the balloon to expand to an expanded and deployed configuration;
• and
• removing the sheath and the balloon delivery system from the body.

A kit for delivering a conformable, fillable balloon to a target location in a body, the kit comprising:

• an access sheath;
• a balloon delivery system comprising:
• an elongate shaft extending from a proximal end to a distal end and defining a first lumen extending from the proximal end to the distal end of the elongate shaft;
• a hypotube extending from a proximal end to a distal end and defining a second lumen extending from the proximal end to the distal end of the hypotube, the hypotube configured to be received in the first lumen of the elongate shaft;
• a conformable, fillable balloon releasably coupled adjacent to the distal end of the elongate shaft, the conformable, fillable balloon expandable from a compressed lower profile delivery configuration to an expanded deployed configuration;
• wherein an interior cavity of the balloon is in fluid communication with the lumen of the elongate shaft;
• and
• wherein the conformable, fillable balloon is configured to contain a filler material and bound a spread of the filler material as the filler material gels or hardens.
