Apparatus and methods for implanting objects, such as a bronchoscopically implanting markers in the lung of patients
First Claim
1. A method of deploying a marker into a lumen within a body, comprising:
- advancing a distal end of a catheter to a desired position in the lumen within the body, wherein the distal end of the catheter is pre-loaded with and releasably retains the marker such that a portion of the marker extends beyond the distal end of the catheter before and during the advancement of the catheter and until deployment, the marker providing a rounded leading edge as the distal end of the catheter is advanced to the desired position in the lumen;
engaging an actuator to move a push wire contained in the catheter toward the distal end of the catheter to engage the marker, the push wire including indicator marks to delineate a predetermined distance to displace the push wire in order to deploy the marker; and
deploying the marker by moving the push wire toward the distal end of the catheter or by fixing the push wire in place and retracting the catheter toward a proximal end of the push wire.

Abstract
Apparatuses and methods for implanting objects, such as a marker, in the lungs of patients. In one embodiment, a bronchoscopic catheter assembly for implanting an object in the lung of a patient includes a handle, a delivery catheter projecting outwardly from the handle, and a push wire contained within the catheter. In one aspect of this embodiment, the catheter can be configured to releasably hold a plurality of markers at a distal end. In another aspect of this embodiment, the push wire can be operably connected to the handle and axially moveable within the delivery catheter to eject the marker out of the catheter within the bronchi of the patient. In a further aspect of this embodiment, the marker can further include an anti-migration device associated with the marker for holding the marker in place once the marker is deployed in the bronchi. The anti-migration device can be integral with the marker or positioned proximate to the marker to prevent migration of the marker.
