Methods and systems for performing a medical procedure

Abstract

Method and system for treating a patient using a compressible, pressure-attenuating device. According to one embodiment, the system is used to treat urinary tract disorders and comprises an access device, a delivery device, a pressure-attenuating device, and a removal device. The access device may be used to create a passageway to an anatomical structure, such as the patient's bladder. The delivery device may be inserted through the passageway created by the access device and may be used to deliver the pressure-attenuating device to the anatomical structure. The removal device may be inserted through the passageway created by the access device and may be used to view the bladder and/or to capture, to deflate and to remove the pressure-attenuating device.

1 - 107 . (canceled) 
     
     
         108 . A delivery device for use in delivering a therapeutic and/or diagnostic object to an anatomical structure within a patient, the delivery device comprising:
 (a) a housing;   (b) a tube extending from a distal end of the housing, the tube having a proximal end, a distal end, and at least one longitudinal channel;   (c) a first fluid supply, the first fluid supply comprising a volume of a first fluid;   (d) a second fluid supply, the second fluid supply comprising a volume of a second fluid; and   (e) a connection system, the connection system connecting each of the first fluid supply and the second fluid supply to the at least one longitudinal channel of the tube.   
     
     
         109 . The delivery device as claimed in  claim 108 , wherein the housing is a gun-shaped housing comprising a barrel portion and a handle portion, the tube extending from a distal end of the barrel portion. 
     
     
         110 . The delivery device as claimed in  claim 109 , wherein the barrel portion comprises a first opening and a second opening, the first opening receiving the first fluid supply, the second opening receiving the second fluid supply. 
     
     
         111 . The delivery device as claimed in  claim 108 , wherein the first fluid supply is a first syringe and wherein the second fluid supply is a second syringe. 
     
     
         112 . The delivery device as claimed in  claim 108 , wherein the connection system comprises a fluid connector, the fluid connector comprising a pair of fluid input channels and a single fluid output channel. 
     
     
         113 . The delivery device as claimed in  claim 110 , wherein the connection system further comprises a first check valve and a second check valve, the first check valve being fluidly connected to one of the fluid input channels by a first fluid line, the second check valve being fluidly connected to the other of the fluid input channels by a second fluid line. 
     
     
         114 . The delivery device as claimed in  claim 108 , wherein the therapeutic and/or diagnostic object is an inflatable medical device, the delivery device further comprising a catheter, the catheter being mounted coaxially around at least the distal end of the tube to store the inflatable medical device in a deflated state, the catheter comprising a window through which the inflatable medical device may be released. 
     
     
         115 . The delivery device as claimed in  claim 114 , wherein the window is a top window. 
     
     
         116 . A delivery device for use in delivering an inflatable medical device to an anatomical structure within a patient, the delivery device comprising:
 (a) a housing;   (b) an inflation tube extending from the housing, the inflation tube comprising a distal end adapted for coupling to an inflatable medical device; and   (c) a decoupling member for decoupling the distal end of the inflation tube from the inflatable medical device;   (d) wherein the housing is marked with markings communicating a sequence of steps for operation of the delivery device.
