Patent number: 8790338Abstract: Some embodiments of a medical instrument can be configured to reduce the formation of coagulum by delivering a negative charge bias to conductive surfaces that interface with blood or bodily tissue during a medical procedure. The application of the negative charge at the instrument-blood interface can reduce the fibrinogen deposition and the formation of coagulum because fibrinogen molecules in general are negatively charged at neutral pH levels. In addition, some embodiments of the instrument may be configured to irrigate the instrument-blood interface with RGD/ClfA peptides, a bicarbonate solution (or other high pH solution), or both to further repel the fibrinogen and thereby inhibit the formation of coagulum. Accordingly, some embodiments of the medical instrument can substantially reduce the risks of thromboembolism during particular medical procedures.Type: GrantFiled: February 13, 2012Date of Patent: July 29, 2014Assignee: Mayo Foundation for Medical Education and ResearchInventors: Samuel J.

Patent number: 8790376Abstract: A method of forming a bone plate comprising fabricating a bone plate to include a first through hole, where at least one of a width and a length of the hole changes along a depth of the hole; plunge milling an interior surface of the bone plate demarcating the first through hole to remove at least a portion of the bone plate to increase at least one of the width and the length of the through hole; and, threading at least a portion of the first through hole.Type: GrantFiled: September 9, 2013Date of Patent: July 29, 2014Assignee: Biomet Manufacturing, LLCInventors: Daniel Duane Fritzinger, Paul G. Kiritsis

Patent number: 8790377Abstract: A bone plate and system is provided. The bone fixation plate conforms to the contour of an irregularly shaped bone and eliminates the need for pre-bending or intraoperative bending of the plate. The bone plate is applied to the bone in a generally flat condition and the process of installing and tightening the bone screws in the prescribed order serves to contour the plate to the underlying bone while providing sufficient strength to effect bone healing. The geometry of the plate allows the plate to follow the contour of an irregularly shaped bone, preventing prominence and patient palpability and streamlining the surgical procedure.Type: GrantFiled: February 21, 2013Date of Patent: July 29, 2014Assignee: MBD Medical LLCInventors: James D. Ralph, Thomas N. Troxell, Mark Michels, Thomas D. Meade

Patent number: 8790378Abstract: A volar distal radius plate includes a shaft and a head. The head includes a radial side that seats below the volar rim, and an ulnar side with two extending tabs that provide a buttress support to ulnar fragments from the volar rim. The tabs are contoured to be atraumatic to the overlying soft tissue. The tabs can be readily re-orientated to better approximate the volar rim and provide close support to the volar fragments. Each tab includes a single hole specifically sized to closely receive a K-wire in a fixed angle orientation, and which permits the K-wire to apply a bending load to a tab in situ to bend the tab about a lower recess between the tab and the remainder of the head. Therefore, the plate does not require a dedicated bender. The tabs can also accommodate sutures.Type: GrantFiled: February 2, 2012Date of Patent: July 29, 2014Assignee: Biomet C.V.Inventors: Alfredo Castaneda, Eduardo A. Ampuero

Patent number: 8790379Abstract: Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone with a bone plate. In various embodiments, the systems and plates provide elastic suspension of the receiving holes relative to an osteosynthesis plate. This elastic suspension can promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments where fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate can enable small, controlled amounts of relative motion between bone fragments connected by the plate. This relative motion can promote fracture healing by callus formation.Type: GrantFiled: June 6, 2012Date of Patent: July 29, 2014Assignee: Zimmer, Inc.Inventors: Michael Bottlang, Steven M. Madey, Kyle Wirtz, Stanley Tsai

Patent number: 8790380Abstract: An orthopaedic device to realign bone segments comprises first and second attachment members and a spacer member. The first attachment member is attached to a first rib bone or first transverse process of a vertebra. The second attachment member is attached to a second rib bone or second transverse process of a vertebra adjacent to the first rib bone or the first transverse process. The spacer member is positioned between the first and second attachment members. The spacer member provides distraction between the first and second rib bones or transverse processes to realign the rib bones. The spacer member is releasably connected to the first and second attachment members. The attachment members comprise a clamp and screw combination.Type: GrantFiled: April 30, 2008Date of Patent: July 29, 2014Assignee: Dynamic Spine, LLCInventor: Glenn R Buttermann

Patent number: 8790381Abstract: Neoplastic tissue, viral and bacterial infections, and other physiological disorders and conditions are treated by irradiation of the host with electromagnetic radiation at a wavelength that is differentially absorbed by the offending tissue or cells. Radiation with differential absorption is also used in the sterilization of articles and packing made from synthetic polymers and for the treatment of food stuffs.Type: GrantFiled: February 20, 2008Date of Patent: July 29, 2014Assignee: Photometics, Inc.Inventor: Brian N. Pierce

Patent number: 8790383Abstract: A method of light therapy includes non-invasive, intra-cranial administration of bright light via the ear canal of a subject by using a light intensity of 0.7-12 lumens, and a treatment time of 1-15 minutes. A medical device including radiation elements for directing the light via the ear canal for use in the light therapy is described.Type: GrantFiled: May 17, 2013Date of Patent: July 29, 2014Assignee: Valkee OyInventors: Antti Aunio, Juuso Nissila
