Abstract

An apparatus and method for performing needle guided interventions and especially needle guided dilations of tissue to create a therapeutic conduit between two luminal organs or structures. The device is particularly useful for creation of an artificial lumen between two hollow body organs using the working lumen of an endoscope.

Claims

1. A method of forming a passageway in the wall of a hollow body organ comprising:

placing an apparatus into the working channel of an endoscope and coupling the apparatus to the proximal end of an endoscope,

positioning the distal end of the endoscope near the wall of a hollow body organ, advancing a needle across the organ wall with a needle actuator to form a passageway and fixing the needle to the endoscope using a locking member, advancing a catheter device having a distal dilation balloon over the needle and through the passageway using a catheter device actuator and fixing the catheter device to the endoscope using a locking member, and

inflating the balloon to enlarge the passageway.

2. The method of claim 1 further comprising:

removing the needle from inside the catheter device and placing one or more guidewires through the catheter device and into the passageway, and

deflating the balloon and withdrawing the apparatus leaving the guidewire to maintain access to the passageway.

3. The method of claim 1, whereby the passageway forms a conduit between the hollow body organ and a duct.

4. The duct of claim 3, where the duct is a pancreatic duct or bile duct.
