International Classification:

A61N 1/36
A61N 1/05
A61B 5/053

Abstract:

Embodiments herein relate to a medical device for treating a cancerous tumor, the medical device having a first lead including a first wire and second wire; a second lead can include a third wire and fourth wire; and a first electrode in electrical communication with the first wire, a second electrode in electrical communication with the second wire, a third electrode in electrical communication with the third wire, and a fourth electrode in electrical communication with the fourth wire. The first and third electrodes form a supply electrode pair configured to deliver one or more electric fields to the cancerous tumor. The second and fourth electrodes form a sensing electrode pair configured to measure an impedance of the cancerous tumor independent of an impedance of the first electrode, the first wire, the third electrode, the third wire, and components in electrical communication therewith. Other embodiments are also included herein.

International Classification:

A61N 1/36
A61N 1/05
A61N 1/378

Abstract:

Embodiments herein relate to a medical device for treating a cancerous tumor, including an electric field generating circuit configured to generate one or more electric fields at or near a site of the cancerous tumor and control circuitry in communication with the electric field generating circuit. The medical device includes one or more supply wires in electrical communication with the electric field generating circuit and one or more supply electrodes. The supply electrodes are configured to deliver an electric field at or near the site of the cancerous tumor. The medical device can include one or more sensing wires in electrical communication with the control circuitry and one or more sensing electrodes. The sensing electrodes can be configured to measure an impedance of the cancerous tumor at at least two different electric field strengths. Other embodiments are also included herein.

Appl. No.:

16/850728

Inventors:

- Maple Grove MN, US
Benjamin Keith Stein - Shoreview MN, US
Keith R. Maile - New Brighton MN, US
Ron A. Balczewski - Bloomington MN, US
Aleksandra Kharam - Maple Grove MN, US

International Classification:

A61N 1/36
A61N 5/06
A61B 10/02

Abstract:

Embodiments herein relate to a method for treating a cancerous tumor located within a subject. The method can include applying one or more electric fields at or near a site of the cancerous tumor, where the cancerous tumor can include a cancerous cell population. The one or more applied electric fields are effective to delay mitosis and cause mitotic synchronization within a proportion of the cancerous cell population. The method can include removing the one or more electric fields to allow mitosis to proceed within the cancerous cell population. The method can include administering a chemotherapeutic agent to the subject after the one or more electric fields have been removed. Other embodiments are also included herein.

Inventors:

- St. Paul MN, US
BENJAMIN K. STEIN - LINO LAKES MN, US

International Classification:

H04N 5/04

US Classification:

348500

Abstract:

Synchronizing video content projected onto a transparent display with switching of pixels in the display. The transparent display has pixels capable of switching between a clear state to make portions of the display transparent and a hazy state to display the projected video. A decoder receives and decodes audio content associated with the video content in order to control the switching of the pixels in the display such that the video content is projected onto pixels in the hazy state.
