Patent number: 9924953Abstract: Described herein are elongate devices for modifying tissue having a plurality of flexibly connected 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 (or formed from) rungs that are flexibly connected. The rungs are typically rigid, somewhat flat and 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. The blades (on the rungs) may be arranged in a staggered arrangement. A tissue-collection or tissue capture element may be used to collect the cut or modified tissue.Type: GrantFiled: September 19, 2016Date of Patent: March 27, 2018Assignee: Amendia, Inc.Inventors: Gregory P. Schmitz, Michael P. Wallace, Ronald Leguidleguid, Nestor C. Cantorna, James Shapiro, Jeffery L. Bleich

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.

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.

Patent number: 8409206Abstract: Described herein are devices, systems and methods for cutting tissue in a patient. In some embodiments, a tissue modification region of a device includes a pair of flexible elongate cutting members extending along the length of the tissue modification region. Each elongate cutting member may be configured to cut a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. In some embodiments, the device includes a spacer. The spacer may be sized and configured to operate in one of two modes. A first mode, in which the spacer is coupled to the cutting members such that it holds a portion of each of the two cutting members a distance from one another, and a second mode, in which at least a portion of the spacer is moved away from a cutting member to allow the cutting members to cut further into tissue.Type: GrantFiled: May 4, 2010Date of Patent: April 2, 2013Assignee: Baxano, Inc.Inventors: Michael P. Wallace, Robert Garabedian, Nestor C. Cantorna, Jeffery L. Bleich, Roy Leguidleguid, Ronald Leguidleguid

Patent number: 8398641Abstract: Described herein are devices and methods for cutting tissue in a patient. In some embodiments, a bimanually controlled device may include a tissue modification region; at least two flexible elongate lengths of cable that extend substantially adjacent to each other proximally to distally; a plurality of rungs extending between the lengths of cable; and a pair of flexible elongate cutting members extending along the length of the tissue modification region of the device. Each elongate cutting member has a thickness cuts a discrete trough into tissue to a depth that is greater than the thickness of the cutting member. The device may further include a substrate sized and configured to releasably hold the cutting members a distance from one another and a pair of couplers positioned toward an outer edge region of the substrate and configured to releasably secure a cutting member to the outer edge region of the substrate.Type: GrantFiled: December 27, 2011Date of Patent: March 19, 2013Assignee: Baxano, Inc.Inventors: Michael P.

Publication number: 20120143206Abstract: Described herein are devices and methods for positioning a wire around a target tissue. In some embodiments, a probe device includes a rigid outer cannula having a curved distal region and a flexible inner cannula slideably disposed within the rigid outer cannula, wherein the inner cannula is configured to assume a curved shape when extended distally from the outer cannula. In some embodiments, the probe device further includes a distal tip at the distal end of the inner cannula and a safety retainer cable coupled to the distal tip and secured to the probe proximally from the distal end of the safety retainer; wherein the safety retainer cable extends proximally from the distal tip and is slack. In some embodiments, the inner cannula comprises an elongate body with a longitudinally extending support member and a longitudinally extending tubular body, configured to pass a wire, disposed inside the elongate body.Type: ApplicationFiled: December 27, 2011Publication date: June 7, 2012Inventors: Michael P.
