Patent number: 10888432Abstract: The preferred embodiment of the present invention is generally described as a lordotic pre-sacral rod implant, or implant construct, for use in association with spinal fusion procedures. In an embodiment, the lordotic pre-sacral rod implant incorporates a washer configured to press against the endplate of the L5 vertebral body and thereby force the vertebral bodies of the lumbosacral junction into a lordotic orientation.Type: GrantFiled: July 27, 2018Date of Patent: January 12, 2021Assignee: Quandary Medical LLCInventors: Gary Fleischer, Brandon Arthurs, Ryan Arce, Leighton LaPierre, Jeffrey R. Schell

Publication number: 20190274728Abstract: An expanding surgical dilator for access to the spine and associated method of use is presented. The method has several steps associated with utilizing the expanding surgical dilator to facilitate the placement of objects, optionally implants and/or instrumentation, through the expanding surgical dilator that exceed the expanding surgical dilator's diameter in its compressed form. The expanding surgical dilator comprises an elastic sheath that can stretch and accommodate and link blades forming the rigid bodies of the sheath.Type: ApplicationFiled: March 6, 2019Publication date: September 12, 2019Applicant: Quandary Medical, LLCInventor: Leighton LaPierre

Patent number: 10368881Abstract: Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.Type: GrantFiled: June 2, 2017Date of Patent: August 6, 2019Assignee: Quandary Medical, LLCInventors: Leighton Joseph LaPierre, Scott Noble, Ryan Alexander Arce, Jeffrey R Schell, Yuta Okkotsu, David C.

Publication number: 20180368994Abstract: The preferred embodiment of the present invention is described as an expandable spinal implant. Generally, the inventor intends for the expandable spinal implant to function as an implant that translates compressive force into anterior-posterior and vertical force to enable the implant to both distract and expand between two endplates of adjacent vertebral bodies, optionally into a lordotic profile.Type: ApplicationFiled: May 29, 2018Publication date: December 27, 2018Applicant: Quandary Medical, LLCInventors: Jeffrey R. Schell, Brandon Arthurs, Ryan Arce, Scott Noble, Leighton Lapierre

Publication number: 20180289504Abstract: The present invention relates to an implant, and more precisely in the preferred embodiment, a fenestrated non-distracting rod for use in association with spinal surgery. The implant is to be placed via the pre-sacral approach in an embodiment of the invention. The fenestrations incorporated within the preferred embodiment are configured to collect bone during transit through the sacrum, and then optionally configured to contact and/or deposit bone collected into the L5-S1 disc space area.Type: ApplicationFiled: April 11, 2018Publication date: October 11, 2018Applicant: Quandary Medical, LLCInventors: Brandon Arthurs, Scott Noble, Ryan Arce, Leighton LaPierre, Jeffrey Schell

Publication number: 20160120661Abstract: The present disclosure presents novel methods, procedures associated steps, and apparatuses to accomplish SI joint fusion in a minimally invasive manner. The preferred embodiment of the invention incorporates improved methods, procedures and apparatuses to facilitate a SI joint fusion providing a generally safer, more minimally invasive SI joint stabilization. In the method associated with the preferred embodiment of the invention, in one aspect, a path or a plurality of paths through an ilium to the sacrum is established, wherein a stabilizer device allows the securement of the sacrum to the ilium. In another aspect, a path or a plurality of paths to the SI joint is established, where bone fusion material allows fusion of the articular surface of the ilium and the articular surface of the sacrum of an SI joint.Type: ApplicationFiled: October 26, 2015Publication date: May 5, 2016Applicant: Quandary Medical, LLCInventors: Gerald R. Schell, Jeffrey R. Schell, David C. Eyvazzadeh, Yuta Okkotsu

Publication number: 20160095721Abstract: Embodiments of the invention are directed to a method of directing medical instruments towards an intervertebral disc space, removing intervertebral disc material from such disc space, and filling such disc space with a material to fuse vertebrae. Embodiments of the invention are further directed to a path that passes structural portions of an ilium. In some aspects, embodiments of the invention are directed to using electro stimulation to avoid certain nerve roots to access an L5-S1 disc space for the purposes of bone fusion.Type: ApplicationFiled: October 5, 2015Publication date: April 7, 2016Applicant: QUANDARY MEDICAL LLCInventors: Gerald Russell Schell, Jeffrey R.
