Abstract

Packaged systems for implanting a marker in a patient and methods for manufacturing and using such systems. In one embodiment, a packaged system comprises an introducer having a cannula and a stylet configured to be received in the cannula, a marker in the cannula, and a package having a sterile compartment. The marker can have a casing configured to be implanted in a patient and a resonating circuit in the casing. The resonating circuit can comprise a coil configured to wirelessly transmit a target signal in response to a wirelessly transmitted excitation signal. The introducer is contained within the sterile compartment. In another embodiment, the marker is not loaded in the introducer within the compartment of the package.

Claims

1. A packaged system for implanting markers in a patient, comprising:

a first introducer having a first cannula and a first stylet configured to be received in the first cannula;

a plurality of markers including a first marker having a first casing configured to be implanted in a patient and a first resonating circuit in the first casing, the first resonating circuit comprising a first coil configured to wirelessly transmit a first target signal in response to a wirelessly transmitted first excitation signal, and the markers including a second marker having a second casing configured to be implanted in the patient and a second resonating circuit in the second casing, the second resonating circuit comprising a second coil configured to wirelessly transmit a second target signal in response to a wirelessly transmitted second excitation signal; and

a package having a tray including a first introducer retainer for holding the first introducer, a first marker retainer for holding the first marker, and a second marker retainer for holding the second marker.

2. The packaged system of claim 1 wherein the first and second markers are preloaded in the introducer.

3. The packaged system of claim 1 wherein the first marker is contained in the first marker retainer and the second marker is contained in the second marker container.
