Detachable balloon embolization device and methods

A balloon embolization apparatus, comprising:

• a catheter including a distal end;
• an inflatable balloon device, wherein the inflatable balloon device includes a cannula detachably mounted on the distal end at a detachable joint, the cannula having a first axial lumen;
• an inflation port defined in a sidewall of the cannula and in fluid communication with the first axial lumen;
• a balloon disposed on the cannula;
• and
• a valve sleeve disposed between the balloon and the cannula, the valve sleeve defining a vent in fluid communication with the balloon,
• wherein the vent forms a hole on the valve sleeve that is angularly and axially offset relative to the inflation port,
• wherein the inflatable balloon device is detachable from the detachable joint of the catheter,
• wherein the valve sleeve fits tightly against the cannula over the inflation port when the balloon is inflated, and
• wherein the valve sleeve presses against the cannula forming a seal over the inflation port in response to a positive pressure within the inflated balloon.
