Methods and systems for performing a medical procedure

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.

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.

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.
