Minimally Invasive Rectal Balloon Apparatus

Abstract

A rectal balloon apparatus has a shaft with a fluid passageway extending therethrough. A balloon is affixed over an end of the shaft such that the fluid passageway communicates with an interior of the balloon. The balloon has a laterally flat surface thereon when inflated. The laterally flat surface of the balloon has a longitudinal groove formed thereon. The balloon having a pair of bulges formed thereon when the balloon is inflated. A ring is affixed to the shaft adjacent the balloon. The shaft has a plurality of holes formed thereon opening to an interior of the balloon.

1 - 20 . (canceled) 
     
     
         21 . A medical balloon device, comprising:
 a first film layer, wherein the first layer includes a first edge;   a second film layer, wherein the second layer includes a second edge joined to the first edge to form a bottom inflatable compartment between the first and second layer;   a third film layer including proximal and distal portions and wherein the third layer includes a third edge joined to the second edge to form a top inflatable compartment between the second and third layer;   an opening in said bottom inflatable compartment to receive a lumen, wherein the bottom inflatable compartment is in fluid communication with the top inflatable compartment; and   wherein the second and third layers are secured intermediate said second and third edges so that the distal portion of the third layer bulges upwardly upon inflation.   
     
     
         22 . The medical balloon device of  claim 21 , wherein the top inflatable compartment is adapted to distend to form a bulged conformation of the distal portion of the third layer relative to the proximal portion upon inflation. 
     
     
         23 . The medical balloon device of  claim 21 , wherein the top inflatable compartment is further secured between the second and third layers intermediate said second and third edges to form an arcuate shape in the distal portion of the third layer upon inflation. 
     
     
         24 . The medical balloon device of  claim 21 , wherein the second and third layers are secured at an intermediate portion so that said third layer upon inflation bulges upwardly between the intermediate portion and the third edge at the distal portion of the third layer.
