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

1-30. -30. (canceled)

31. In localization systems that involve implanting markers in a patent, a method for manufacturing a packaged system for implanting a marker in a patient, comprising:

providing a first marker having a first casing configured to be implanted in a patient and a first resonating circuit in the first casing, wherein the first resonating circuit comprises a first coil configured to wirelessly transmit a first target signal in response to a wirelessly transmitted first excitation signal;

preloading the first marker into a first cannula of a first introducer; and

sealing the first introducer with the first marker in the first cannula in a compartment of a package.

32. The method of claim 31, further comprising:

providing a second marker having a second casing configured to be implanted in the patient and a second resonating circuit in the second casing, wherein the second resonating circuit comprises a second coil configured to wirelessly transmit a second target signal in response to a wirelessly transmitted second excitation signal; and

preloading the second marker into the first cannula of the first introducer before sealing the first introducer in the compartment of the package.

33. The method of claim 32 wherein providing the first marker comprises configuring the first resonating circuit to have a first frequency, and providing the second marker comprises configuring the second resonating circuit to have a second frequency different than the first frequency.

34. The method of claim 32 wherein providing the first marker comprises configuring the first resonating circuit to have a first frequency, and providing the second marker comprises configuring the second resonating circuit to have the first frequency.

35. The method of claim 32, further comprising placing a spacer in the cannula between the first and second markers.

36. The method of claim 31, further comprising:

providing a second marker having a second casing configured to be implanted in the patient and a second resonating circuit in the second casing, wherein the second resonating circuit comprises a second coil configured to wirelessly transmit a second target signal in response to a wirelessly transmitted second excitation signal; and

preloading the second marker into a second cannula of a second introducer; and

sealing the second introducer in the compartment of the package with the first introducer.

37. The method of claim 36 wherein providing the first marker comprises configuring the first resonating circuit to have a first frequency, and providing the second marker comprises configuring the second resonating circuit to have a second frequency different than the first frequency.

38. The method of claim 36 wherein providing the first marker comprises configuring the first resonating circuit to have a first frequency, and providing the second marker comprises configuring the second resonating circuit to have the first frequency.

39. The method of claim 36, further comprising placing a spacer in the cannula between the first and second markers.

40. In localization systems for determining the location of a target site in a patient, a method for manufacturing and handling a packaged system for implanting a marker in the patient, comprising:

providing a first marker having a first casing configured to be implanted in a patient and a first resonating circuit in the first casing, wherein the first resonating circuit comprises a first coil configured to wirelessly transmit a first target signal in response to a wirelessly transmitted first excitation signal;

preloading the first marker into a first cannula of a first introducer;

sealing the first introducer with the first marker in the first cannula in a compartment of a package; and

transporting the first introducer with the first marker in the first cannula in the compartment of the package to a customer.
