Patent number: 11759192Abstract: A retractor, preferably a nerve root retractor, comprising three components: a base portion, an arm portion, and an anatomical structure retractor portion. The nerve retractor is designed to eliminate the requirement of having a person hold the retractor tool during a surgical procedure. The nerve retractor can be secured to a portion of the anatomical structure involved with, or near the surgical procedure site, and utilizes an actuating device which allows the user to manipulate the angle of orientation of the arm portion or anatomical structure retractor portion. The anatomical structure retractor may comprise a modular anatomical structure engaging member/head, allowing the surgeon to use multiple or differently configured structure engaging members/heads during a procedure as needed.Type: GrantFiled: January 24, 2020Date of Patent: September 19, 2023Assignee: SNJ Patents, LLCInventors: Stefan C. Theofilos, Charles S. Theofilos, Krutik Chaten Shah

Patent number: 11702311Abstract: A device for dispensing rolled items, such as tape. The hand-held or mounted tape dispensing device is designed to accommodate variously sized or shaped rolls of tape. The tape dispensing device for dispensing a tape may comprise a support structure and one or more tape holder sliders configured to be moveable from a first position to at least one second position. The tape dispensing device may also include one or more tape holder sliders, which may move simultaneously in a single direction. The tape dispensing device may also include a tape dispenser blade having a cutting edge and configured to be moveable from a first position to at least one second position and to rotate to a position along the cutting edge at different angles.Type: GrantFiled: August 30, 2022Date of Patent: July 18, 2023Assignee: SNJ Patents, LLCInventors: Charles S.

Publication number: 20230083239Abstract: A surgical instrument for delivering fluids or other agents or materials to an injection site, such as a surgical, treatment or tissue site. The surgical instrument comprises a multiple dispensing unit housing needle configured to house a plurality of fluid or materials dispensing units, or sub-needles, a needle cover sleeve, and an outer cannula. The surgical instrument is configured to provide fluid or materials to multiple areas of a surgical or treatment site during a single injection period, without having to remove the needle and re-insert to position it to inject fluid to another area of the surgical or treatment site.Type: ApplicationFiled: September 13, 2022Publication date: March 16, 2023Inventor: Charles S. THEOFILOS, M.D.

Publication number: 20230016652Abstract: A retractor, preferably a nerve root retractor, comprising three components: an upper portion, a mid-portion, and a lower portion. The nerve retractor is designed to eliminate the requirement of having a person hold the retractor tool during a surgical procedure. The nerve retractor can be secured to a portion of the anatomical structure involved with, or near, the surgical procedure site, and utilizes an actuating device which allows the user to manipulate the angle of orientation of the arm portion or anatomical structure retractor portion. The anatomical structure retractor may comprise a modular anatomical structure engaging member/head, allowing the surgeon to use multiple or differently configured structure engaging members/heads during a procedure as needed.Type: ApplicationFiled: September 27, 2022Publication date: January 19, 2023Inventors: Charles S.

Publication number: 20140128476Abstract: An implant having shape forming and hardening functionality is described. The implant is formed from shape memory materials. The implant is formed from a shape memory alloy, shape memory polymer, or combinations thereof, to provide them with the ability to be compressed into a shape that facilitates minimally invasive insertion. Subsequent to such insertion, the shape memory materials provide the implant with the ability to regain its original shape and size. Subsequently, the implant becomes rigid, thereby providing strength, structural integrity and support.Type: ApplicationFiled: November 1, 2013Publication date: May 8, 2014Applicant: Boo Holdings, LLCInventor: Charles S.

Patent number: 8523947Abstract: An implant assembly is disclosed, and includes an implant member and a plate configured to be coupled with the implant member. The plate defines a horizontal plane and includes at least one bore through the plate. The bore has an inlet aperture and at least one exit aperture. The inlet aperture has a curvilinear seat. A fastener is configured for insertion through the at least one bore, and the fastener has a curved portion. The curved portion of the fastener is configured to contact the contact the curvilinear seat to secure the plate to the implant member.Type: GrantFiled: May 8, 2012Date of Patent: September 3, 2013Assignee: Spartan Cage Holding, LLCInventor: Charles S.

Patent number: 8187329Abstract: The present disclosure is directed towards a biomechanical implant and anterior, lateral or posterior instrumentation construct. The construct may be of unitary or modular construction, whereby a single molded construction can form the entire assembly, in which case the through holes may be adapted to receive a metallic insert for screw fixation; or alternatively be of a modular construction wherein the anterior/lateral instrumentation and intervertebral spacer are designed for removable locking engagement, one with the other, for insertion by the surgeon as a unitary construct.Type: GrantFiled: February 22, 2010Date of Patent: May 29, 2012Assignee: Spartan Cage Holding, LLCInventor: Charles S.

Publication number: 20100023018Abstract: The application describes a bilateral drilling and screw placement guide adapted for fixation to the spinous process of a vertebral body. The positioning and surgical guiding instrument is adapted for use during a spinal surgical procedure in conjunction with a drilling tool, fastening device, e.g. a pedicle screw, K-wire or the like. The guide includes an engagement device for attachment to a region of the spinous process, to which an adjustably attached support member is affixed. This allows for immobilizing the guide upon the spinous process anatomical landmark, in a specific orientation with respect thereto. The guide includes a bilaterally adjustable drill guide assembly for precise anatomical positioning of the drill and screw placement guides bilaterally about the sagittal, axial and coronal planes so as to enable the defining of a plurality of drilling axes extending toward the vertebral body.Type: ApplicationFiled: July 22, 2009Publication date: January 28, 2010Inventor: Charles S.
