1. A deflation catheter device, comprising:
- a catheter tube having a lumen, a proximal end, a distal end, and wall extending between the proximal and distal ends, wherein the catheter tube includes an aspiration hole configured to provide fluid communication between an interior of an implanted balloon device and the lumen of the catheter tube while the aspiration hole is extended within the implanted balloon device, and wherein the aspiration hole includes at least one side hole in the wall of the catheter tube between the proximal and distal ends of the catheter tube;
a stylet slideably disposed within the lumen of the catheter tube and configured to extend beyond the distal end of the catheter tube to puncture a wall of the implanted balloon device, wherein the aspiration hole is configured to provide fluid communication between the interior of the implanted balloon device and the lumen when the stylet is disposed within the lumen and wherein the aspiration hole further comprises a hole at the distal end of the catheter tube and the stylet, and wherein the gap is configured to provide fluid communication between the lumen of the catheter tube and an interior of the implanted balloon device while extended within the implanted balloon device;
a handle disposed at a proximal end of the catheter tube and attached to the stylet, wherein the handle is configured to controllably advance, retract, and rotate the stylet relative to the catheter tube; and
a suction port disposed at a proximal end of the catheter tube and being m fluid communication with the lumen of the catheter tube.
