Patent number: 9681813Abstract: The present invention provides methods and apparatus that allow the surgeon and the IONM specialist to continuously get a feedback on the relative proximity from the instruments to a nerve and on the health of this nerve. By having a coupling device that allows every instrument to be electrically stimulated, the surgeon, through the instruments, continuously sends a small electrical input into the patient's body and depending on the relative proximity between this electrical stimulation and a nerve, a neuromonitoring modality is recorded through electrodes placed on the patient. The characteristics of this response allow the IONM specialist to determine the health status and or location of the nerves.Type: GrantFiled: May 1, 2012Date of Patent: June 20, 2017Assignee: DINNOS TECHNOLOGYInventors: Fabrice Chenaux, Jean-Sebastien Merette

Publication number: 20160354209Abstract: Methods and systems for installing a glenosphere using a patient specific instrument within a joint are discussed. For example, a method for implanting a glenosphere comprises installing first and second pins in a glenoid cavity using a patient specific instrument that sets a distance between the guide pins, installing an implant at the location of the second guide pin, and guiding a glenosphere onto the implant using a helper connected to the first pin. In another example, a glenosphere helper comprises a cup shaped body having an interior surface for engaging at least a portion of an outer surface of the glenosphere, and a flange extending from the cup to receive a guide pin at a point, the flange extending from the cup shaped body such that the point is positioned outside a periphery of the glenosphere.Type: ApplicationFiled: May 16, 2016Publication date: December 8, 2016Inventors: William Van Kampen, Steve Dunstan, Jean-Sebastien Merette, Anselm Jakob Neurohr

Publication number: 20160089153Abstract: A method of creating a patient specific instrument (PSI) for use in knee replacement surgery is described which includes performing at least two X-ray scans of a bone, each of the X-ray scans being taken from different angular positions, generating a digital bone model of the bone based solely on the X-ray scans, planning the PSI based on the digital bone model, including determining locations for one or more anchor points on the PSI which are adapted to abut a surface of the bone, the determined locations of the anchor points being disposed on the PSI at locations corresponding to areas of expected high accuracy on the digital bone model generated by the X-ray scans. The areas of expected high accuracy include at least a peripheral bone contour in at least one of the angular position of the X-ray scans. A suite of such PSI instruments is also described.Type: ApplicationFiled: September 25, 2014Publication date: March 31, 2016Inventors: Pierre COUTURE, Trong Tin NGUYEN, Anselm Jakob NEUROHR, Jean-Sébastien MÉRETTE

Publication number: 20150073424Abstract: A pin placement instrument for placing a pin in a bone comprises an anatomical interface with a hook-like portion being opened in a lateral direction of the instrument to receive a bone therein in a planned position. A drill guide is connected to the anatomical interface and defining at least one guide slot in a longitudinal direction of the instrument. The guide slot has a lateral opening over its full length in the drill guide to allow lateral withdrawal of the instrument in said lateral direction with the pin placed in the bone passing through the lateral opening. A bushing is removably placed in said guide slot via said longitudinal direction in a planned fit, the bushing defining a throughbore aligned with the guide slot and adapted to receive the pin extending in said longitudinal direction when the bushing is in the guide slot for pin placement.Type: ApplicationFiled: March 28, 2013Publication date: March 12, 2015Inventors: Pierre Couture, Jean-Sebastien Merette, Alain Richard, Jean-Guillaume Abiven, Thomas Gourgon

Patent number: 8784458Abstract: An improved insert for assembly with a bone plate is described. The insert has a first opening adapted to receive a set screw and a second opening adapted to receive a bone screw. The insert is connectable to the bone plate using a set screw. The insert in conjunction with the set screw provides an improved range of relative motion for placing the bone screw at outboard locations with respect to the bone plate. That way, bone fragments that are not necessarily reachable using the bone plate without the insert can be secured together for improved healing.Type: GrantFiled: October 13, 2009Date of Patent: July 22, 2014Assignee: Greatbatch Medical S.A.Inventors: Patrick M.

Patent number: 8454609Abstract: An acetabular reamer comprising: a body defining a rotation axis about which the acetabular reamer is rotatable; a reaming element movable between a reaming element inner position and a reaming element outer position relative to the body; an actuator for moving the reaming element between the reaming element inner and outer positions; and a reaming element lock configurable between a locked configuration and an unlocked configuration. In the unlocked configuration, the reaming element is freely movable by the actuator between the reaming element inner and outer positions. In the locked configuration, the reaming element lock prevents the reaming element from moving relative to the body. In use, when the reaming element lock is in the locked configuration and reaction forces are exerted onto the reaming element, a larger portion of the reaction forces is transmitted to the body than to the actuator.Type: GrantFiled: August 21, 2008Date of Patent: June 4, 2013Assignee: École de Technologie SupérieureInventors: Yvan Petit, Julio Fernandes, Jean-Sebastien Merette, Mathieu Dansereau, Victor Songmene, Mathieu Carrier

Publication number: 20100312285Abstract: The present invention relates to a bone plate designed to secure locking screws inserted into the plate at various angles. The interior wall surface of the plate apertures include a series of protruding threaded ridges interspaced by relief notches. The threaded ridges and intermediate relief notches of the bone plate in combination with the threaded ridges and intermediate relief notches of the locking screw head allow the locking screw to bypass or “lump” threads of the bone plate. Thus, the locking screw can be inserted into the bone plate at a first angle and part-way through its advancement along the threads of the bone plate that angle can be changed. The second angle can either be greater than the first with respect to an orientation perpendicular to a longitudinal axis of the bone plate, or less than. This gives the physician a great amount of flexibility during a surgical procedure.Type: ApplicationFiled: May 20, 2010Publication date: December 9, 2010Applicant: Greatbatch Ltd.Inventors: Patrick M.
