Patent number: 8403964Abstract: A system for restricting spinal flexion includes superior and inferior tether structures joined by a pair of compliance members. Compliance members comprise tension members which apply a relatively low elastic tension on the tether structures. By placing the tether structures on or over adjacent spinous processes, flexion of a spinal segment can be controlled in order to reduce pain.Type: GrantFiled: August 8, 2011Date of Patent: March 26, 2013Assignee: Simpirica Spine, Inc.Inventors: Louis Fielding, Ian Bennett, Manish Kothari, Todd Alamin, Hugues Malandain, Craig Litherland, Colin Cahill

Patent number: 8394128Abstract: A constraining apparatus includes a constraining structure that captures a first and a second anatomical structure. A motion limiting member coupled with the constraining structure is adapted to provide a force resistant to relative movement of the first anatomical structure away from the second anatomical structure. A regulating member is detachably coupled with the motion limiting member or the constraining structure and is adapted to change the resistant force provided by the motion limiting member when the regulating member is in direct engagement with the motion limiting member or constraining structure.Type: GrantFiled: April 27, 2011Date of Patent: March 12, 2013Assignee: Simpirica Spine, Inc.Inventors: Manish Kothari, Louis Fielding, Colin Cahill, Anand Parikh

Patent number: 8308771Abstract: A surgical fastening mechanism for releasably locking an implantable tether includes a housing having a central channel. The housing has an entry aperture, an exit aperture and a side channel extending therebetween. A roller element has a sidewall with an aperture therethrough and the roller is slidably disposed at least partially in the central channel such that the entry and exit apertures are at least partially aligned with the roller aperture. This permits passage of the tether therethrough. Rotation of the roller element in a first direction winds the tether around the roller thereby creating a friction interface between the roller element, the housing and the tether. A locking mechanism is operably connected with either the housing or the roller element and is adapted to prevent rotation of the roller in the central channel and also adapted to prevent release of the tether from the roller.Type: GrantFiled: June 5, 2009Date of Patent: November 13, 2012Assignee: Simpirica Spine, Inc.Inventors: Ian Bennett, Louis Fielding, Hugues Malandain, Todd Alamin

Publication number: 20120059419Abstract: A method for coupling a prosthesis to a spinal segment in a patient includes the steps of selecting first and second reference points disposed along the spinal segment and pre-operatively measuring a target distance. The target distance extends between the first and second reference points while the patient is in a preferred posture such as the standing position. A prosthesis is coupled to the spinal segment and the prosthesis is then intra-operatively adjusted in order to set the distance between the first and second reference points based on the target distance.Type: ApplicationFiled: February 28, 2011Publication date: March 8, 2012Applicant: Simpirica Spine, Inc.Inventors: Todd Alamin, Manish Kothari, Hugues Malandain, Colin Cahill, Louis Fielding

Publication number: 20110288589Abstract: Fastening mechanisms for releasably locking a tether are provided. The mechanisms find application with orthopedic internal-fixation implants and make the implants more reliable and their implantation less invasive. A method for releasably locking a tether comprises advancing the tether through a tether aperture in a clamp body. The tether enters the tether aperture in a first plane and exits in a second plane generally transverse to the first plane. Positioning a fastener element in a fastener aperture in the clamp body captures the tether between the clamp body and the fastener element thereby releasably locking the tether in position relative to the clamp body.Type: ApplicationFiled: November 23, 2010Publication date: November 24, 2011Applicant: Simpirica Spine, Inc.Inventors: Louis Fielding, Hugues Malandain, Ian Bennett, Todd Alamin

Publication number: 20110172708Abstract: A system for restricting spinal flexion includes a compliance member having a body and an elongation limit. The body typically comprises a spring or other tension element which provides elastic constraint to the spinal segment when the compliance member is attached to the spinous processes. The elongation limit prevents overextension of the compliance member, thus reducing the likelihood that the patient will experience over flexion of the spinal segment and reducing the risk of placing excessive mechanical load on the compliance member.Type: ApplicationFiled: March 28, 2011Publication date: July 14, 2011Applicant: SIMPIRICA SPINE, INC.Inventors: LOUIS FIELDING, IAN BENNETT, MANISH KOTHARI, TODD ALAMIN, HUGUES MALANDAIN, CRAIG LITHERLAND, COLIN CAHILL
