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 can include one or more of 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.

         20 . An access device with locking everting sleeve, comprising:
 a handle;   an elongate, tubular body extending distally from the handle and having a proximal end, a distal end, and a central lumen;   a cannulated obturator, removably carried within the lumen;   a one directional slide ring surrounding and axially slidable with respect to the tubular body, the slide ring comprising at least one inwardly and distally extending protrusion engaged with the tubular body and configured to restrain distal movement of the slide ring relative to the tubular body while allowing proximal movement; and   an everting sleeve, initially extending from the cannulation on the obturator around a distal end of the tubular body and to the slide ring carried by the tubular body, wherein proximal movement of the slide ring advances the everting sleeve out of the obturator and over the outside of the tubular body.   
     
     
         21 . The access device of  claim 20 , further comprising first and second tubes in communication with the lumen and a fluid control system operable to manually control fluid flow through the first and second tubes, the fluid control system moveable between at least three positions to—1) simultaneously close the first and second tubes, 2) close only the first tube, and 3) close only the second tube—without obstruction of the central lumen. 
     
     
         22 . The access device of  claim 20 , wherein the tubular body further comprises at least one axially-extending, exterior groove and the at least one protrusion mating with the at least one axially-extending, exterior groove in such a way as to restrain rotation of the slide ring relative to the tubular body. 
     
     
         23 - 37 . (canceled) 
     
     
         38 . 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 a distal end of the housing, the inflation tube having a proximal end, a distal end, and a longitudinal channel, the distal end of the inflation tube being insertable into an inflatable medical device for use in delivering at least one inflation medium to the inflatable medical device; and   (c) a push-off member slidably mounted relative to the inflation tube, the push-off member comprising a distal end slidable distally past the distal end of the inflation tube to decouple the inflation tube from the inflatable medical device.   
     
     
         39 . The delivery device as claimed in  claim 38  further comprising a first inflation medium supply, the first inflation medium supply comprising a volume of a first inflation medium, the first inflation medium supply being coupled to the longitudinal channel of the inflation tube. 
     
     
         40 . The delivery device as claimed in  claim 38  further comprising a trigger, the trigger being coupled to the push-off member. 
     
     
         41 . The delivery device as claimed in  claim 38  further comprising a catheter, the catheter being mounted coaxially around at least the distal end of the inflation tube and a distal end of the push-off member to store an inflatable medical device in a deflated state, the catheter comprising a window through which the inflatable medical device may be released. 
     
     
         42 . The combination of the delivery device of  claim 41  and an inflatable medical device, the inflatable medical device being disposed within the catheter and being mounted on the distal end of the inflation tube. 
     
     
         43 . 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, the housing comprising a first opening, a second opening and a third opening;   (b) a trigger, the trigger being pivotally mounted on the housing;   (c) an inflation tube extending through the second opening of the housing, the inflation tube having a proximal end, a distal end, and a longitudinal channel, the distal end of the inflation tube extending distally from the second opening of the housing and being insertable into an inflatable medical device for use in delivering at least one inflation medium to the inflatable medical device;   (d) a push-off member coupled to the trigger and slidably mounted relative to the inflation tube, the push-off member comprising a distal end slidable distally past the distal end of the inflation tube to decouple the inflation tube from the inflatable medical device;   (e) a first syringe, the first syringe being mounted within the first opening of the housing and comprising a volume of a first inflation medium, the first inflation medium being air, the first syringe being adapted for connection to the at least one longitudinal channel of the inflation tube; and   (f) a second syringe, the second syringe being mounted within the third opening of the housing and comprising a volume of a second inflation medium, the second inflation medium being at least one liquid perfluorocarbon, the second syringe being adapted for connection to the at least one longitudinal channel of the inflation tube;   (g) wherein the housing is marked with markings communicating a sequence of steps for operation of the delivery device.   
     
     
         44 . The delivery device as claimed in  claim 43  wherein the markings communicate first dispensing the volume of at least one liquid perfluorocarbon from the second syringe, then dispensing the volume of air from the first syringe, then actuating the trigger to release the inflatable medical device, and then removing the delivery device from the patient.
