Publication number: 20190388126Abstract: An interspinous implant is provided. The interspinous implant can include a first member having a first end and a second end. At least one of the first end and the second end can include a mating portion. The interspinous implant can also include a second member, which can have a first end, a second end and at least one receiving portion formed adjacent to at least one of the first end and the second end. The at least one receiving portion can receive the mating portion to couple the first member to the second member at a desired orientation. The interspinous implant can also include a first extension, which can be substantially opposite the mating portion, and adapted to engage a spinous process. The interspinous implant can comprise a second extension, which can be substantially opposite the at least one receiving portion, and adapted to engage a second process.Type: ApplicationFiled: July 11, 2019Publication date: December 26, 2019Inventors: Garrett A.

Patent number: 8747445Abstract: An enclosure device connecting a pedicle fixation device with an elongated spinal fixation member. The enclosure device can include an enclosure member and an elongated guide member affixed to the enclosure member and defining a fracture region for breaking off the guide member from the enclosure member. The enclosure member can have a spherical outer surface rotatably received within a receiver portion of the pedicle fixation device. The enclosure member can include an internal bore capable of slidably receiving the fixation member.Type: GrantFiled: January 15, 2007Date of Patent: June 10, 2014Assignee: EBI, LLCInventor: Nathaniel E. Hawkins

Patent number: 8721722Abstract: An intervertebral implant and associated method. The intervertebral implant can include a first component having a first articulating surface and a first bone engagement surface for engaging a first vertebra, and a second component having a second articulating surface and a second bone engagement surface for engaging a second vertebra adjacent to the first vertebra. The first and second articulating surfaces articulate with each other for substantially replicating a natural spinal movement. The first and second bone engagement surfaces define an outer surface substantially shaped as an envelope of five cylinders.Type: GrantFiled: December 6, 2006Date of Patent: May 13, 2014Assignee: EBI, LLCInventors: Gretchen Dougherty Shah, Hyun Bae, Ryan C. Lakin, Nathaniel E. Hawkins

Patent number: 8337527Abstract: A spinal connector includes a first seat having a first opening for coupling to a first spinal connecting member along a first longitudinal axis and a second seat having a second opening for coupling to a second spinal connecting member along a second longitudinal axis. The second longitudinal axis is substantially coaxial to the first longitudinal axis for connecting the first and second connecting members end to end. The spinal connector also includes a ball enclosure rotatably received in the second opening of the second seat. The ball enclosure defines a bore along the second longitudinal axis and articulates with the second opening for allowing change of orientation of the second connecting member relative to the first connecting member.Type: GrantFiled: April 8, 2008Date of Patent: December 25, 2012Assignee: EBI, LLCInventors: Nathaniel E. Hawkins, Nicholas J. Bender, Rui J. Ferreira

Patent number: 7294129Abstract: A spinal fixation device. The spinal fixation device includes a plurality of arm assemblies. Each arm assembly can be attached to a single vertebra. Pairs of adjacent arm assemblies can be movably coupled to one another by one or more telescopic assemblies. The telescopic assemblies can oriented substantially transversely to the vertebrae and allow relative movement between the vertebrae.Type: GrantFiled: February 18, 2005Date of Patent: November 13, 2007Assignee: EBI, L.P.Inventors: Nathaniel E Hawkins, Stephen Esses, Kirk J Bailey, Rui J Ferreira

Patent number: 6913586Abstract: Apparatus for determining a dorsiflexion angle of a surgical patient's foot relative to the corresponding leg during tendon surgery. The apparatus includes a leg member having a first support adapted for engaging at least one of a lateral malleolus and a medial malleolus of the patient, and a second support opposing the first support adapted for engaging another of the lateral malleolus and the medial malleolus of the patient. The apparatus further includes a foot member rotatably connected to the leg member for selectively rotating the foot member relative to the leg member about an axis defined by the first support and the second support of the leg member. The foot member has a metatarsal support adapted for engaging a predetermined point on at least one preselected metatarsal bone of the patient.Type: GrantFiled: October 14, 2003Date of Patent: July 5, 2005Assignee: Barnes-Jewish HospitalInventors: Jack Engsberg, Kelly Jean King-Ellison, Nathaniel E.
