Methods And Systems For Laterally Stabilized Constraint Of Spinous Processes

View page
US Patent:
8029541, Oct 4, 2011
Filed:
Jul 13, 2007
Appl. No.:
11/777366
Inventors:
Todd Alamin - Woodside CA, US
Ian Bennett - San Francisco CA, US
Colin Cahill - San Francisco CA, US
Louis Fielding - San Carlos CA, US
Assignee:
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/70
US Classification:
606248, 606250, 606263
Abstract:
A spinal implant for limiting flexion of the spine includes a tether structure for encircling adjacent spinal processes. Usually, a pair of compliance members will be provided as part of the tether structure for elastically limiting flexion while permitting an extension. A cross-member is provided between the compliance member or other portions of the tether structure to stabilize the tether structure and prevent misalignment after implantation.

Methods And Systems For Constraint Of Multiple Spine Segments

US Patent:
8162982, Apr 24, 2012
Filed:
Apr 17, 2009
Appl. No.:
12/426119
Inventors:
Todd Alamin - Woodside CA, US
Ian Bennett - San Francisco CA, US
Louis Fielding - San Carlos CA, US
Colin Cahill - San Francisco CA, US
Assignee:
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/70
US Classification:
606248
Abstract:
Methods, apparatus and systems for constraining spinous processes to elastically limit flexion of two or more adjacent spinal segments rely on placing a tether structure over at least three adjacent vertebral bodies or two adjacent vertebral bodies and the sacrum. The tether structures may be continuous, for example in the form of a continuous loop, or may be discontinuous, for example in the form of a loop or elongate element having at least two anchor structures for securing in bone.

US Patent:
8187307, May 29, 2012
Filed:
Apr 17, 2009
Appl. No.:
12/426167
Inventors:
Todd Alamin - Woodside CA, US
Ian Bennett - San Francisco CA, US
Louis Fielding - San Carlos CA, US
Colin Cahill - San Francisco CA, US
Manish Kothari - San Rafael CA, US
Assignee:
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/88
A61B 17/70
US Classification:
606279, 606246, 606248
Abstract:
Spinous process constraint structures include a first attachment element for placement over a first spinous process and a second attachment element for placement over a second spinous process. The attachment elements are joined by a single connector which may optionally include a compliance member for providing controlled elasticity between the spinous processes.

Methods And Devices For Controlled Flexion Restriction Of Spinal Segments

US Patent:
8403961, Mar 26, 2013
Filed:
Apr 18, 2008
Appl. No.:
12/106103
Inventors:
Louis Fielding - San Carlos CA, US
Ian Bennett - San Francisco CA, US
Manish Kothari - San Rafael CA, US
Todd Alamin - Woodside CA, US
Hugues Malandain - Mountain View CA, US
Craig Litherland - Palo Alto CA, US
Colin Cahill - San Francisco CA, US
Assignee:
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/70
US Classification:
606263, 606246, 606248
Abstract:
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.

US Patent:
8454660, Jun 4, 2013
Filed:
Aug 9, 2011
Appl. No.:
13/206339

Assignee:
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/70
US Classification:
606249, 606263
Abstract:
A spinal implant for limiting flexion of the spine includes a tether structure for encircling adjacent spinal processes.

Methods And Systems For Constraint Of Spinous Processes With Attachment

View page
US Patent:
8523904, Sep 3, 2013
Filed:
Jul 13, 2007
Appl. No.:
11/827980
Inventors:
Todd Alamin - Woodside CA, US
Ian Bennett - San Francisco CA, US
Louis Fielding - Portland OR, US
Colin Cahill - San Francisco CA, US
Assignee:
The Board of Trustees of the Leland Stanford Junior University - Palo Alto CA
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/58
A61B 17/00
US Classification:
606246
Abstract:
Spinal implants for limiting flexion of the spine are implanted between a superior spinous process and an inferior spinous process or sacrum. The implants include upper straps which are placed over the upper spinous process, while the lower portions of the implant are attached to the adjacent vertebra or sacrum. The attachments may be fixed, for example using screws or other anchors, or may be non-fixed, for example by placing a loop strap through a hole in the spinous process or sacrum.

US Patent:
8529606, Sep 10, 2013
Filed:
Mar 10, 2010
Appl. No.:
12/721238
Inventors:
Todd Alamin - Woodside CA, US
Colin Cahill - Portola Valley CA, US
Louis Fielding - San Carlos CA, US
Manish Kothari - San Rafael CA, US
Assignee:
Simpirica Spine, Inc. - San Carlos CA
International Classification:
A61B 17/88
A61B 17/70
US Classification:
606279, 606248, 606263
Abstract:
Methods and apparatus for controlling flexion in a spinal segment of a patient include performing a spinal fusion procedure on a pair of adjacent vertebrae in the spinal segment and implanting a constraint device into the patient. Adjusting length or tension in the constraint device allows the constraint device to provide a force a force resistant to flexion of the spinal segment undergoing fusion. The constraint device also modulates loads borne by the spinal segment undergoing fusion or tissue adjacent thereto.
