Abstract: An embodiment in accordance with the present invention provides an implanted catheter and an external device that the patient uses to inject a therapeutic into the implanted tube. The implanted catheter can be equipped with a fixation mechanism that secures the catheter in place and eases physician insertion and removal. The fixation mechanism can include shape memory arms having silicone tips or can be a second catheter branch configured to hold the device in the user's sinus cavity. The catheter can also include numerous exit holes to prevent obstruction and deliver the therapeutic. An interface between the implanted catheter and the external device is incorporated, to ensure a reliable seal for medication passage. A method and device for delivery of the catheter to the correct position can also be included.

Abstract: Apparatus, assemblies, and methods for capturing objects within a body are disclosed. A surgical snare device includes a steerable deflection portion with a steerable distal tip. An interface is linked to the steerable deflection portion to selectively manipulate the distal tip. A snare loop disposed at the distal tip can have a length that remains substantially constant as the distal tip is deflected and the snare loop moves in concert with the distal tip. The distal tip may deflect up to at least one-hundred eighty degrees, while the snare loop moves a corresponding amount. A method includes extending a snare through a body lumen and to a location near an object. The snare may have a loop that changes positions while maintaining the same length. The loop may be placed around an object and then used to retrieve the object from the body lumen.
