Publication number: 20180235789Abstract: Methods and devices relate to the use and construction of a vascular stent. A stent assembly includes mesh structure that is at least partially attached to a support or stent structure. The stent structure is formed of one or more struts that collectively form a tubular body sized to fit within a blood vessel. The mesh structure is formed of one or more filaments or sutures that are interwoven or knit to form a structure that is coupled to the stent structure. The mesh structure can at least partially cover or at least be partially covered by the stent structure.Type: ApplicationFiled: February 21, 2018Publication date: August 23, 2018Inventors: Michael P. Wallace, Herbert Mendoza, Roy Leguidleguid

Publication number: 20170172586Abstract: Devices and methods of modifying tissue for low profile and ultra profile rongeur devices to treat spinal tissue. These devices may include a curved or curveable distal region; the cutting member may be configured to operate in the curved region. Also described herein are tissue modification devices that may be flexible or bendable for positioning in the tissue (including the spinal region) but can be made rigid once in position, or otherwise fixed in place to allow leverage when modifying the tissue.Type: ApplicationFiled: January 5, 2017Publication date: June 22, 2017Applicant: Amendia, Inc.Inventors: Michael P.

Patent number: 9351741Abstract: A device for removing tissue from a patient may include an elongate flexible body having a proximal end, a distal end, and a longitudinal axis therebetween, the elongate body having opposed first and second major surfaces with a lateral orientation across the axis, and a plurality of blades distributed laterally across the first major surface. Each blade may have a first end adjacent the first surface and extending to a cantilevered second end, a first edge between the first and second ends of the blade being oriented toward the distal end of the elongate body, a second edge between the first and second ends of the blade being oriented toward the proximal end of the elongate body, a height of the blade between its first and second ends, and an axial length of the blade between its first and second edges.Type: GrantFiled: November 15, 2013Date of Patent: May 31, 2016Assignee: Amendia, Inc.Inventors: Gregory P. Schmitz, Jeffery L. Bleich, Steven A. Spisak, Roy Leguidleguid, Jefferey Bleam

Patent number: 9320618Abstract: 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: GrantFiled: October 25, 2013Date of Patent: April 26, 2016Assignee: Amendia, Inc.Inventors: Gregory P. Schmitz, Michael P. Wallace, Winnie Tang, Amie R. Borgstrom, Jeffery L. Bleich, Gregory B. Arcenio, Ronald Leguidleguid, Roy Leguidleguid, Jefferey Bleam

Patent number: 9314253Abstract: Devices and methods for cutting tissue in a patient. In some embodiments, a bimanually controlled device may include a tissue modification region; one or more (e.g., two) flexible elongate length of cable that extend proximally to distally, a tissue modification region along a portion of the length of cable; and a guidewire coupler at the distal end of the device for attaching the distal end of the tissue modification device to the proximal end of a guidewire. Method of using these devices (including devices having two or more parallel length of cutting regions) to cut tissue (e.g., spinal lamina) are also described.Type: GrantFiled: February 1, 2013Date of Patent: April 19, 2016Assignee: Amendia, Inc.Inventors: Ronnie I. Mimran, Amie R. Borgstrom, Michael P. Wallace, Robert Garabedian, Roy Leguidleguid

Patent number: 8845639Abstract: Described herein are elongate devices for modifying tissue having a plurality of flexibly connected and rungs or links, and methods of using them, including methods of using them to decompress stenotic spinal tissue. These devices may be included as part of a system for modifying tissue. In general, these devices include a plurality of blades positioned on for formed from) rungs that are flexibly connected and may be separated by one or more spacers. The rungs are typically wider than they are long (e.g., rectangular). The rungs may be arranged, ladder like, and may be connected by a flexible connector substrate or between two or more cables. Different sized rungs may be used, or rungs with different cutting properties. In some variations the tissue modification devices may have a non-linear axial shape, or may be converted from a first axial shape to a second axial shape.Type: GrantFiled: January 14, 2011Date of Patent: September 30, 2014Assignee: Baxano Surgical, Inc.Inventors: Michael P. Wallace, Robert Garabedian, Gregory P. Schmitz, Jeffery L. Bleich, Nestor C. Cantorna, Ronald Leguidleguid, Roy Leguidleguid, Michael Sheinberg

Patent number: 8845637Abstract: A method and system for guiding at least a portion of a surgical device to a desired position between two tissues in a patient's body involves coupling a guidewire to the device and pulling the distal end of the guidewire to guide at least a portion of the surgical device to a desired position between the two tissues. The surgical device generally includes one or more guidewire coupling members and may comprise a tissue access device. A system may include a guidewire and a surgical device. In some embodiments, a guidewire, a tissue access device, and one or more additional devices to use with the access device may be provided. Methods, devices and systems may be used in open, less-invasive or percutaneous surgical procedures, in various embodiments.Type: GrantFiled: September 11, 2013Date of Patent: September 30, 2014Assignee: Baxano Surgical, Inc.Inventors: Gregory P.

Publication number: 20140276848Abstract: Tissue modification devices, and particularly very low-profile, yet strong and manipulatable Rongeur devices. In general, these devices are low-profile, with a flat and thin distal end that may be much thinner than it is wide. The distal end includes a cutting window within which one or more blades move to cut tissue. The distal end region and the curved region forming an angle with an elongate rigid body may be sufficiently stiff and rigid so that the distal end can be pushed (or pulled) against a tissue to be cut with sufficient force so that even hard tissue such as bone may be held within the window and cut by the blade(s).Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Inventors: Roy LEGUIDLEGUID, Michael P. WALLACE, Nestor C. CANTORNA
