The intervertebral distractor has a distraction main body to be inserted between two adjacent spinous processes to provide a corresponding support, and a first and a second pair of lateral stabilizers, rotatably connected to the main body, which pairs are arranged respectively in correspondence of or near to a first and a second end of the latter, the stabilizers of each pair being able to assume a spread apart configuration projecting with respect to the main body so as to be able to engage from a respective side the spinous apophyses, holding in position the main body itself, wherein, in such projecting configuration, each stabilizer has a tilt with respect to the frontal plane that is equal to about 30 degrees.Type: ApplicationFiled: November 23, 2010Publication date: December 12, 2013Inventors: Giuseppe Calvosa, Raphael Bartalesi, Miria Tenucci

Patent number: 8603142Abstract: An implantable device and method for fixation of spinous processes is presented. The device has first and second spaced plates configured for attachment to portions of adjacent spinous processes. The device also has an implant configured for insertion between two adjacent spinous processes. The method has the steps of assembling the components of the implantable device and otherwise inserting them into position onto, between, and/or adjacent two desired spinous processes.Type: GrantFiled: December 5, 2010Date of Patent: December 10, 2013Inventor: James C. Robinson

Publication number: 20130325067Abstract: An interspinous intervertebral distractor is described. The intervertebral distractor has a main body to be inserted between two adjacent spinous processes to provide a related support, a first and a second pair of lateral stabilizers, arranged respectively in correspondence of a first and a second end of the main body, and a rod that is percutaneously actuatable and has a shaped profile to cause the spreading apart of the stabilizers of the first pair, and of the second pair.Type: ApplicationFiled: November 23, 2010Publication date: December 5, 2013Inventors: Giuseppe Calvosa, Raphael Bartalesi, Miria Tenucci

Publication number: 20130325066Abstract: Medical devices and related methods for the treatment of spinal conditions are described herein. In one embodiment, a method includes disposing at least a portion of a support member into a space between adjacent spinous processes. The support member defines a lumen between a proximal end and a distal end of the support member. An expandable member is inserted through the lumen of the support member such that a distal end portion of the expandable member is disposed outside a distal end of the lumen and a proximal end portion of the expandable member is disposed outside a proximal end of the lumen. The distal end portion and the proximal end portion of the expandable member are then expanded such that each of the distal end portion and the proximal end portion of the expandable member has an outer diameter greater than an outer diameter of the support member.Type: ApplicationFiled: August 6, 2013Publication date: December 5, 2013Applicant: KYPHON SARLInventor: Andrew C. Kohm

Patent number: 8591547Abstract: Various interspinous process spacing devices and associated methods are provided for treating spinal disease. In one embodiment, an interspinous process spacing device includes a first attachment side and a second attachment side, each attachment side including one or more slots formed therein and positioned proximate one end for receiving fasteners extending inwardly from a second interspinous process spacing device. The device further includes a spacer tray extending from the first attachment side and slideably insertable through a spacer tray slot formed in the second attachment side, wherein the spacer tray is adapted to retain adjacent spinous processes in a spaced apart orientation, and wherein at least a portion of the spacer tray has a longitudinally arcuate shape adapted to facilitate angled insertion of the spacer tray through the spacer tray slot. The device further includes securing means for securing the second attachment side relative to the first attachment side.Type: GrantFiled: March 14, 2011Date of Patent: November 26, 2013Assignee: Southern Spine, LLCInventors: Hugh F. Smisson, III, David C. Field, Brandi L. Bohleber, Hiywot Yilma, Michael A. Cowan

Patent number: 8591549Abstract: Medical devices for the treatment of spinal conditions are described herein. The medical device includes a main body that is adapted to be placed between the L5 vertebra and the sacrum so that the main body acts as a spacer with respect to the L5 vertebra and the sacrum to maintain distraction therebetween when the spine moves in extension. The main body is formed from a material having a gradual variation in modulus.Type: GrantFiled: April 8, 2011Date of Patent: November 26, 2013Assignee: Warsaw Orthopedic, Inc.Inventor: Eric C. Lange

Patent number: 8591546Abstract: A spinal implant adapted to be inserted into an interspinous space between adjacent spinous processes includes a proximal section, a central section, and a distal section disposed sequentially along a longitudinal axis. The distal section has feature(s) that allow the implant to be inserted laterally into the interspinous space, such as an approximately helical groove and/or a thread-like structure. The distal tip of the implant tapers inwardly, and may be rounded. The proximal section may include an outwardly extending wing or flange. The implant may include a main body that includes the wing or flange and a spacer slidably mated to the main body through the wing or flange.Type: GrantFiled: December 7, 2011Date of Patent: November 26, 2013Assignee: Warsaw Orthopedic, Inc.Inventors: James F.
