Abstract
An anchoring mechanism and method for anchoring a device within a biological conduit include an expandable element configured for retaining the device at a desired angle relative to a central axis of the biological conduit. A steering mechanism is preferably provided for orienting the device prior to operation of the anchoring mechanism. The anchoring mechanism and method are employed in drug delivery devices, brachytherapy devices or for anchoring a catheter or sheath to provide a working channel for reliable guidance of a wide range of tools to a target location within the body.
Claims6
An anchoring cage for deployment in a biological conduit comprising:
- a cage body configured to act against an interior surface of a biological conduit in a predefined orientation relative to a central axis of a biological conduit;
- and
- a lumen formed through the cage body for accepting a distal portion of a catheter and oriented such that a central axis of the lumen is non-parallel to the central axis of the biological conduit.
The anchoring cage of 1, wherein the anchoring cage comprises at least one filamentous element.
