Publication number: 20130053851Abstract: 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: August 17, 2012Publication date: February 28, 2013Inventors: Gregory P. Schmitz, Michael P. Wallace, Winnie Chung, Amie R. Borgstrom, Jeffery L. Bleich, Gregory B. Arcenio, Ronald Leguidleguid, Roy Leguidleguid, Jefferey Bleam

Patent number: 8096994Abstract: An apparatus includes an elongate member configured to engage a spinal implant and a locking member. The locking member is disposed at a distal end portion of the elongate member. The locking member is configured to move relative to the elongate member between a first position and a second position in a direction substantially perpendicular to a center line of the elongate member. The locking member is configured to allow the distal end portion of the elongate member to move relative to the spinal implant when in the first position. The locking member is configured to couple the distal end portion of the elongate member to the spinal implant when in the second position.Type: GrantFiled: March 29, 2007Date of Patent: January 17, 2012Assignee: Kyphon SARLInventors: Christopher U.

Patent number: 8012164Abstract: An auger is axially fixed to and positioned within a cutter. The auger and cutter advance at the same time relative to a contact structure placed against a vessel, penetrating the wall of the vessel and cutting a tissue plug. When the auger and the cutter are retracted from the vessel wall, the tissue plug is retained by the auger and cutter and removed from the vessel wall. The auger and the cutter thus create an opening in the vessel wall, without the need for a prior incision in that wall.Type: GrantFiled: January 22, 2002Date of Patent: September 6, 2011Assignee: Cardica, Inc.Inventors: Brendan M. Donohoe, Theodore M. Bender, Brian R. DuBois, Scott O. Chamness, Stephen A. Yencho, Jaime S. Vargas, Nathan H. White, Gregory B. Arcenio, Heather L. Klaubert, Russell C. Mead, Jr.

Publication number: 20110060314Abstract: 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: ApplicationFiled: October 25, 2010Publication date: March 10, 2011Inventors: Michael P.

Publication number: 20100331900Abstract: Described herein are pullwire handle devices for securing to a tissue-penetrating pullwire. In some embodiments, the device includes a handle body, a pullwire lock configured to removably lock the pullwire handle device onto a pullwire within the handle body, and a tip containment element configured to retain the distal tip of the pullwire. In some embodiments, the handle body further comprises a storage chamber configured to store a distal portion of the pullwire. Also described herein are methods for capturing a pullwire using a pullwire handle device. In some embodiments, the method includes the steps of inserting the distal end of a pullwire into the pullwire handle device, advancing the pullwire further into the pullwire handle device while the distal portion of the pullwire is contained within the pullwire handle device, and locking the distal portion of the pullwire within the pullwire handle device.Type: ApplicationFiled: June 25, 2010Publication date: December 30, 2010Applicant: Baxano, Inc.Inventors: Robert Garabedian, Amie R.

Publication number: 20100331883Abstract: Described herein are methods and systems for precisely placing and/or manipulating devices within the body by first positioning a guidewire or pullwire through the body from a first location, around a curved pathway, and out of the body through a second location, so that the distal and proximal ends of the guidewire extend from the body, then pulling a device into position using the guidewire. 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 the 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.Type: ApplicationFiled: June 16, 2010Publication date: December 30, 2010Inventors: Gregory P. Schmitz, Michael P. Wallace, Winnie Chung, Amie R. Borgstrom, Jeffery L. Bleich, Gregory B. Arcenio, Ronald Leguidleguild, Roy Leguidleguild
