Apparatus And Methods For Performing Cellular Electro-Manipulations

View page
US Patent:
20080103529, May 1, 2008
Filed:
Oct 26, 2006
Appl. No.:
11/553310
Inventors:
KARL H. SCHOENBACH - Norfolk VA, US
Tammo Heeren - Norfolk VA, US
Assignee:
Old Dominion University - Norfolk VA
International Classification:
A61N 1/18
US Classification:
607 2
Abstract:
An intracellular electro-manipulation apparatus for delivery an electric field pulse to a target of one or more biological cells is provided. The apparatus includes a pulse generator that generates an ultrashort electric field pulse, and a pulse delivery system that directs the ultrashort electric field pulse to the target. The apparatus can include a reflected-signal impeder connected between the pulse generator and the pulse delivery system to impede reflection of a signal to the pulse generator when impedance mismatching between the pulse delivery system and pulse generator occurs. Alternatively, or additionally, the apparatus can include a current limiter connected between the pulse generator and the pulse delivery system to limit current between the pulse generator and the pulse delivery system when a high-conductivity condition occurs in the target.

Inventors:
KARL H. SCHOENBACH - Norfolk VA, US
Stephen J. Beebe - Norfolk VA, US
Tammo Heeren - Aliso Viejo CA, US
Juergen F. Kolb - Norfolk VA, US
Shu Xiao - Norfolk VA, US

International Classification:
A61N 1/05
US Classification:
607 2
Abstract:
A medical instrument for delivering electrotherapy to tissue that includes an outer support member having a ground plate at a distal end of the outer support member, and a protrusive element having a tip that extends beyond the ground plate. A portion of the protrusive element proximate the ground plate can act as an electrical insulator and a portion of the protrusive element proximate the distal end of the protrusive element can include a first electrode. The protrusive element can be designed to penetrate into tissue below a tissue surface while a tissue contacting surface of the ground plate rests against the tissue surface. Also disclosed are systems incorporating the medical instrument and methods of electrotherapy to subsurface tissue using the medical instrument.

US Patent:
20110118728, May 19, 2011
Filed:
Nov 13, 2009
Appl. No.:
12/618244
Inventors:
Tammo Heeren - Aliso Viejo CA, US
John C. Huculak - Mission Viejo CA, US
Steven W. Kovalcheck - Aliso Viejo CA, US
Assignee:
ALCON RESEARCH, LTD. - Fort Worth TX
International Classification:
A61F 9/007
A61B 18/12
US Classification:
606 34
Abstract:
An eye surgery apparatus includes a HIPEF probe comprising at least two electrodes and is configured for delivery of a high-intensity pulsed electrical field to a surgical site within an eye via the electrodes. Embodiments also include a transducer configured to monitor one or more surgical parameters within the eye during application of the high-intensity pulsed electrical field to the surgical site, a pulse generation circuit configured to generate a series of electrical pulses for application to the electrodes to create the high-intensity pulsed electrical field, and a control circuit, operatively connected to the at least one transducer and the pulse generation circuit and configured to automatically adjust one or more characteristics of the series of electrical pulses, based on the one or more monitored surgical parameters. With these apparatus, the amount of energy delivered can be limited to levels necessary for effective operation without over-exposing the vitreous.

High-Intensity Pulsed Electric Field Vitrectomy Apparatus With Load Detection

View page
US Patent:
20110118729, May 19, 2011
Filed:
Nov 13, 2009
Appl. No.:
12/618335
Inventors:
Tammo Heeren - Aliso Viejo CA, US
John C. Huculak - Mission Viejo CA, US
Steven W. Kovalcheck - Aliso Viejo CA, US
Assignee:
ALCON RESEARCH, LTD - Fort Worth TX
International Classification:
A61B 18/18
US Classification:
606 41
Abstract:
A high-intensity pulsed electric field (HIPEF) vitrectomy apparatus is disclosed. An exemplary apparatus includes a HIPEF probe comprising at least one electrode disposed at a distal end of the HIPEF probe, such that the distal end is configured for insertion into an eye. A load detection circuit is coupled to the HIPEF probe and is configured to compare a measured physical parameter to a corresponding threshold value. A control circuit is electrically coupled to the load detection circuit and configured to selectively disable application of pulsed energy to the at least one electrode of the HIPEF probe, based on the comparison. The measured physical parameter may include, for example, resistivity, permittivity, reflected light, pressure, or heat dissipation capability.

US Patent:
20110118734, May 19, 2011
Filed:
Nov 16, 2009
Appl. No.:
12/618805
Inventors:
Jack R. Auld - Laguna Niguel CA, US
Tammo Heeren - Aliso Viejo CA, US
John C. Huculak - Mission Viejo CA, US
Steven W. Kovalcheck - Aliso Viejo CA, US
Assignee:
ALCON RESEARCH, LTD. - Fort Worth TX
International Classification:
A61B 18/18
US Classification:
606 45
Abstract:
A capsulorhexis apparatus is disclosed. An exemplary apparatus includes a cutting electrode device that in turn comprises a handle, a flexible ring having a single ring-shaped wire electrode embedded therein, and a shaft connecting the flexible ring to the handle, wherein the flexible ring is configured for insertion into an eye through an incision. The apparatus further includes a grounding electrode configured for placement in or on the eye, independently of the cutting electrode device, and a pulse generator electrically connected to the ring-shaped wire electrode and the grounding electrode and configured to supply pulsed power to the eye via the ring-shaped wire electrode and the grounding electrode

Localized Pharmacological Treatment Of Ocular Tissue Using High-Intensity Pulsed Electrical Fields

View page
US Patent:
20110144562, Jun 16, 2011
Filed:
Dec 14, 2009
Appl. No.:
12/637302
Inventors:
Tammo Heeren - Aliso Viejo CA, US
John C. Huculak - Mission Viejo CA, US
Steven W. Kovalcheck - Aliso Viejo CA, US
Assignee:
Alcon Research, LTD. - Fort Worth TX
International Classification:
A61F 9/00
A61K 9/127
A61P 27/02
A61N 1/30
US Classification:
604 20, 424450
Abstract:
A high-intensity pulsed-electrical-field (HIPEF) apparatus treats ocular tissue within a localized portion of an eye with a pharmacological solution. To mitigate risk of damage to adjacent, healthy ocular tissue, the apparatus delivers the solution to only a portion of the eye and then alters the effectiveness of at least some of the solution delivered by applying a HIPEF. In some embodiments, for example, the apparatus delivers an inactive pharmacological solution and then activates at least some of the solution by applying a HIPEF to that solution. As the apparatus applies the HIPEF with high precision, the HIPEF only activates solution within select portions of the eye. In other embodiments, the apparatus delivers a pharmacological carrier encapsulating an active pharmacological solution and then penetrates the carrier by applying a HIPEF. Delivered with a high concentration, but low dose, the solution diffuses only to tissue within a localized portion of the eye.

Localized Shockwave-Induced Tissue Disruption

View page
US Patent:
20110144638, Jun 16, 2011
Filed:
Dec 14, 2009
Appl. No.:
12/637362
Inventors:
Tammo Heeren - Aliso Viejo CA, US
John C. Huculak - Mission Viejo CA, US
Steven W. Kovalcheck - Aliso Viejo CA, US
Assignee:
Alcon Research, LTD. - Fort Worth TX
International Classification:
A61F 9/007
A61B 18/18
US Classification:
606 41
Abstract:
A high-intensity pulsed-electrical-field (HIPEF) apparatus removes ocular tissue from a localized portion of an eye by delivering one or more focused shockwaves to that tissue. In one embodiment, for example, the apparatus generates one or more electrical pulses, delivers the one or more focused shockwaves to ocular tissue by applying the generated electrical pulses to a HIPEF probe, and then removes the ocular tissue disrupted by the one or more focused shockwaves via aspiration. To mitigate risk of damage to adjacent ocular tissue, the apparatus delivers the one or more focused shockwaves with energy substantially limited to the tissue being removed. The HIPEF apparatus is, therefore, especially advantageous in the context of cataract surgery where cataract tissue need be broken apart and removed without damaging adjacent tissue associated with the lens capsule required to implant an intraocular lens.
