Abstract
A medical device for creating a fistula in a patient has a catheter including a first lumen and a second lumen for forming a fistula inside a body organ of a patient is disclosed. The second lumen may be capable of fluid communication with an internal bolster, wherein the internal bolster is attachable to the catheter near the distal end and is at least partially filled with a liquid. An external bolster may be adjustably attachable to the catheter outside the patient. Methods of use of medical devices according to the present invention are also disclosed. In one aspect of a method of use, at least a portion of the liquid within an internal bolster may be removed. Such a process may substantially collapse the internal bolster for removal of the medical device.

39. A gastrostomy device, comprising:
-
a catheter including a bolster control lumen and a fistulous lumen; an internal bolster positioned at a distal end of the catheter, the internal bolster including an inflatable body in fluid communication with the bolster control lumen, the inflatable body having a deflated state and an inflated state larger than the deflated state, the deflated state imparting a removal force of about 5 lbs. or less; a pull device attached to a proximal end of the catheter; and a syringe connectable to the bolster control lumen to transition the inflatable body from the inflated state to the deflated state. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58)
