Patent number: 9498295Abstract: Systems and processes for the optimization of laser treatment of an eye are disclosed. The process can include receiving a set of parameters of a laser treatment (e.g., an aerial beam size, contact lens, pulse duration, and the desired clinical grade), determining an estimated size of a lesion to be generated by the laser treatment beam, receiving a lesion pattern density (e.g., full grid, mild grid, or other), and determining a recommended pattern of laser treatment beam spots. The recommended pattern of laser treatment beam spots may include a recommended number of laser treatment spots and a spacing between the spots.Type: GrantFiled: August 2, 2012Date of Patent: November 22, 2016Assignee: TOPCON MEDICAL LASER SYSTEMS, INC.Inventor: Daniel V.

Publication number: 20160287441Abstract: A system and method for treating ophthalmic target tissue, including a light source for generating a beam of light, a beam delivery system that includes a scanner for generating patterns, and a controller for controlling the light source and delivery system to create a dosimetry pattern of the light beam on the ophthalmic target tissue. One or more dosage parameters of the light beam vary within the dosimetry pattern, to create varying exposures on the target tissue. A visualization device observes lesions formed on the ophthalmic target tissue by the dosimetry pattern. The controller selects dosage parameters for the treatment beam based upon the lesions resulting from the dosimetry pattern, either automatically or in response to user input, so that a desired clinical effect is achieved by selecting the character of the lesions as determined by the dosimetry pattern lesions.Type: ApplicationFiled: June 14, 2016Publication date: October 6, 2016Applicant: Topcon Medical Laser Systems, Inc.Inventors: Daniel V.

Publication number: 20160262933Abstract: Patterned laser treatment of the retina is provided. A visible alignment pattern having at least two separated spots is projected onto the retina. By triggering a laser subsystem, doses of laser energy are automatically provided to at least two treatment locations coincident with the alignment spots. All of the doses of laser energy may be delivered in less than about 1 second, which is a typical eye fixation time. A scanner can be used to sequentially move an alignment beam from spot to spot on the retina and to move a treatment laser beam from location to location on the retina.Type: ApplicationFiled: May 9, 2016Publication date: September 15, 2016Inventors: MARK BLUMENKRANZ, DANIEL V.

Patent number: 9254168Abstract: Electrosurgical therapy is provided with an electrode array configured to ablate tissue during insertion of the electrode array into tissue being treated. Once the electrode array is fully inserted, deep heating of the treated tissue can be performed by applying an additional waveform to the tissue with the electrode array. Optionally, the electrical waveform can be varied continuously during insertion of the electrode array to control the extent of coagulation at the side walls and at the bottom of the channels produced by tissue ablation.Type: GrantFiled: March 16, 2010Date of Patent: February 9, 2016Assignee: MEDTRONIC ADVANCED ENERGY LLCInventor: Daniel V.
