Patent number: 11382647Abstract: Described herein are devices, systems and methods for treating target tissue in a patient's spine. In general, the methods include the steps of advancing a wire into the patient from a first location, through a neural foramen, and out of the patient from a second location; connecting a tissue modification device to the wire; positioning the tissue modification device through the neural foramen using the wire; modifying target tissue in the spine by moving the tissue modification device against the target tissue; and delivering an agent to modified target tissue, wherein the agent is configured to inhibit blood flow from the modified target tissue. In some embodiments, the step of modifying target tissue comprises removing target tissue located ventral to the superior articular process while avoiding non-target tissue located lateral to the superior articular process.Type: GrantFiled: June 27, 2018Date of Patent: July 12, 2022Assignee: Spinal Elements, Inc.Inventors: Michael P. Wallace, Robert Garabedian, Gregory B. Arcenio, Jeffery L. Bleich, Vahid Saadat, Winnie Chung

Publication number: 20140107709Abstract: Described herein are methods and systems for precisely placing and/or manipulating devices within the body by first positioning a guidewire or pullwire. The device to be positioned within the body is coupled to the proximal end of the guidewire, and the device is pulled into the body by pulling on the distal end of the guidewire that extends from the body. The device may be bimanually manipulated by pulling the guidewire distally, and an attachment to a device that extends proximally, allowing control of both the proximal and the distal ends. In this manner devices (and particularly implants such as innerspinous distracters, stimulating leads, and disc slings) may be positioned and/or manipulated within the body. Guidewire exchange systems, devices and methods are also described. A guidewire may be exchanged between different surgical devices and may be releaseably or permanently coupled.Type: ApplicationFiled: October 25, 2013Publication date: April 17, 2014Inventors: Gregory P. SCHMITZ, Michael P. WALLACE, Winnie CHUNG, Amie R. BORGSTROM, Jeffery L. BLEICH, Gregory B. ARCENIO, Ronald LEGUIDLEGUID, Roy LEGUIDLEGUID, Jefferey BLEAM

Publication number: 20090318914Abstract: The invention provides a system, devices, and methods for ablating abnormal epithelial tissue of the uterine cervix. Embodiments of an ablation device include an operative head with a support surface adapted to conformably engage and therapeutically contact the cervix, and an energy delivery element on the support surface. The energy delivery element is configured to deliver energy, such as RF energy, to the tissue in a manner that controls the surface area and depth of ablation. The device may further include a shaft and a handle to support the ablation device, and may further include a speculum to facilitate access to the cervix. A system to support the operation of the ablation device includes a generator to deliver energy to the energy delivery element.Type: ApplicationFiled: November 13, 2008Publication date: December 24, 2009Inventors: David S.
