Claim:
A medical device for retrieving a foreign object within a body lumen, comprising: an intravascular device configured to capture a foreign object within a body lumen; an elongated shaft having a proximal section and a distal section; an inflation lumen extending from the proximal section of the elongated shaft to the distal section of the elongated shaft; and an expandable sleeve having a proximal end and a distal end bonded to the distal section of the elongated shaft and in fluid communication with the inflation lumen, wherein a portion of the expandable sleeve is removably secured to the elongated shaft by an adhesive layer disposed about a portion of the elongated shaft and is configured to release from and unfold along the adhesive layer as the balloon unfolds distally beyond the distal section of the elongated shaft as it begins to envelop a proximal portion of the intravascular device, thereby retrieving the intravascular device.
