Patent number: 8196589Abstract: A wireless marker for localizing a target of a patient comprises a casing and a magnetic transponder at least partially received in the casing. The magnetic transponder produces a wirelessly transmitted magnetic field in response to a wirelessly transmitted excitation energy. The magnetic transponder also has a magnetic centroid. The marker also comprises an imaging element carried by the casing and/or the magnetic transponder. The imaging element has a radiographic profile in a radiographic image such that the marker has a radiographic centroid at least approximately coincident with the magnetic centroid.Type: GrantFiled: December 24, 2003Date of Patent: June 12, 2012Assignee: Calypso Medical Technologies, Inc.Inventors: Margo Gisselberg, Keith Seiler, Steven C. Dimmer

Publication number: 20090278689Abstract: A miniature resonating marker assembly that includes, in one embodiment, a ferromagnetic core, a wire coil disposed around the core, and a capacitor connected to the wire coil adjacent to the magnetic core. The core, coil, and capacitor form a signal element that, when energized, generates a magnetic field at a selected resonant frequency. The magnetic field has a magnetic center point positioned along at least one axis of the signal element. An inert encapsulation member encapsulates the signal element therein and defines a geometric shape of the resonating marker assembly. The geometric shape has a geometric center point substantially coincident with the magnetic center point along at least a first axis of the signal element. The shape and configuration of the assembly also provides for a miniature signal element specifically tuned to resonate at a selected frequency with a high quality factor.Type: ApplicationFiled: May 18, 2009Publication date: November 12, 2009Inventors: Margo Gisselberg, Eric Hadford, Steven C. Dimmer, Jack Goldberg, Jeff Pelton, Kurt Zublin

Publication number: 20090209804Abstract: Apparatuses and methods for percutaneously implanting objects, such as radioactive seeds or markers, in patients. In one embodiment, a device for percutaneously implanting an object in a patient includes a handle, a cannula projecting outwardly from the handle, and an actuator movably disposed relative to the handle. In one aspect of this embodiment, the cannula can be configured to releasably hold the object and percutaneously penetrate the patient. In another aspect of this embodiment, the actuator can be operably connected to the cannula and operable to move the cannula relative to the handle and release the object within the patient. In a further aspect of this embodiment, the cannula can include a tip portion having a restriction configured to releasably hold the object for implantation in the patient.Type: ApplicationFiled: July 25, 2005Publication date: August 20, 2009Applicant: Calypso Medical technologies, Inc.Inventors: Keith Seiler, Eric Hadford, Margo Gisselberg

Publication number: 20070213616Abstract: A targeting catheter is used to locate an arteriotomy, such as is formed during a femoral artery catheterization procedure. The targeting catheter includes one or more targeting aids, such as an inflatable balloon or sensor (e.g., Doppler or temperature sensor), to locate the arteriotomy. The targeting aid may be positioned at the arteriotomy. An ultrasonic beacon on the catheter may then be located relative to a therapeutic ultrasonic applicator (e.g., by using acoustic time-of-flight) so that the focus of ultrasonic energy from the applicator can be aligned with the arteriotomy.Type: ApplicationFiled: October 19, 2006Publication date: September 13, 2007Inventors: Thomas Anderson, Charles Emery, Margo Gisselberg, John Kook, Larry Kulesa, Robert Pedersen, David Perozek, K.
