Patent number: 9028516Abstract: A surgical instrument for use in releasing soft tissue within the human body. The surgical instrument has a handle with proximal and distal ends with a tube connected to the distal end. The surgical instrument also includes a blade member that slidingly engages the tube moving along the length of the tube to cut soft tissue. Further included in the surgical instrument is a guard member that is attached to the blade member. The guard member has a hood portion and a capture portion. The hood portion is connected to the blade member with the distally positioned capture portion acting to displace surrounding tissue while capturing certain soft tissue structures resulting in the blade member being in operative position to cut and release the soft tissue. A surgical instrument kit including a plurality of modular surgical instruments and method for releasing soft tissue using the surgical instrument are also disclosed.Type: GrantFiled: October 15, 2013Date of Patent: May 12, 2015Assignee: Del Palma OrthopedicsInventors: Andrew K. Palmer, Dale Dellacqua, Jeffrey A. Farris

Publication number: 20150073559Abstract: A vertebral body replacement device includes a body member and a central rod member having two threaded portions and configured to be operatively associated with the body member. The device also includes a first end member and a second end member with the end members configured to threadingly engage the threaded portions of the central rod member. The body member and the two end members are further constructed to inhibit rotational movement of the two end members when the device is positioned within a space within a spine as the two end members will engage the adjacent respective vertebral bodies following rotational actuation of the central rod member causing the end members to move in an axial direction relative to the body member, thereby allowing the two end members to apply a force to the two vertebral bodies. A surgical instrument and method for using the device are also disclosed.Type: ApplicationFiled: November 17, 2014Publication date: March 12, 2015Inventors: Daniel Refai, Jeffrey A. Farris

Patent number: 8840669Abstract: Variable height intervertebral devices and method of employing the devices are disclosed. The devices and methods can maintain or re-establishing anatomic spacing along a spine and can ensure avoidance of long-term structural, neurological, vascular, and/or other systemic impairments. The intervertebral device includes a cylindrical body having a first end and a second end opposite the first end; a first disk threaded to the first end of the cylindrical body and a second disk mounted to the second end of the cylindrical body; means for rotating the cylindrical body whereby the first disk translates along the cylindrical body to vary the height of the device; and a plurality of pins mounted to one disk, the plurality of pins slidably engageable with a plurality of sleeves mounted to the other disk, the pins and sleeves inhibiting the first disk from rotating when the cylindrical body is rotated.Type: GrantFiled: April 13, 2010Date of Patent: September 23, 2014Assignee: Biomet Spine, LLCInventors: Jeffrey A.

Patent number: 8702719Abstract: The surgical instrument includes a handle assembly and an elongate body that has first and second ends with the first end being located adjacent to the handle assembly and the second end being moveably connected to an implant engagement assembly. The surgical instrument also has a length control mechanism that includes a gripping portion, a drive shaft and a gear assembly. The surgical instrument further has a locking mechanism that includes a gripping portion, a connecting rod and a coupling end. The length control mechanism functions to adjust the overall length of an implant that is held by the implant engagement assembly before being implanted in vivo. The locking mechanism operates to secure the overall length of the implant following final length adjustment and implantation. A surgical method for using the surgical instrument, a method of fabrication and a spinal implant insertion kit is also disclosed.Type: GrantFiled: December 6, 2011Date of Patent: April 22, 2014Assignee: Aesculap Implant Systems, LLCInventors: Daniel Refai, Jeffrey T.
