Device for controlled endoscopic penetration of injection needle
First Claim
1. An endoscopic needle device, comprising:
- a handle;
a catheter sheath connected to the handle, the catheter sheath having at least one lumen extending therethrough;
a needle selectively movable within the at least one lumen between a needle retracted position and a needle extended position; and
a stabilization element selectively movable within the at least one lumen between a stabilizer retracted position and a stabilizer extended position.

Abstract
An endoscopic needle device comprises a handle and a catheter sheath connected to the handle, wherein the catheter sheath has at least one lumen, for example a needle lumen and a stabilization lumen, extending therethrough. A needle is selectively movable within the needle lumen between a needle retracted position and a needle extended position and a stabilization element is selectively movable within the stabilization lumen between a stabilizer retracted position and a stabilizer extended position. A linking mechanism may operatively connect the needle and the stabilization element so that when the needle is in the needle retracted position the stabilization element is in the stabilizer extended position and when the needle is in the needle extended position the stabilization element is in the stabilizer retracted position.

26. A method of injecting a needle into an injection site using an endoscopic needle device, the endoscopic needle device including a handle, a catheter sheath connected to the handle, a stabilization element disposed at a distal end of the needle device, and a needle disposed at the distal end of the needle device, comprising the steps of:
-
inserting the needle device into a body;
delivering the needle device to an injection site;
applying the stabilization element to stabilize the injection site; and
penetrating the injection site with the needle. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
