Filed:

Jan 11, 2012

Appl. No.:

13/348034

Inventors:

Jason A. Bryan - Avon Lake OH, US
Joseph P. Iannotti - Strongsville OH, US
Wael K. Barsoum - Bay Village OH, US

International Classification:

A61B 17/56

US Classification:

606102

Abstract:

A distance indicator for indicating the distance that a device has traveled includes an elongate housing with a guidewire connector configured for operative connection to a guidewire to hold the housing stationary with respect thereto. A plunger is operatively connected to the housing for longitudinal motion with respect to the housing. A first plunger end is configured to operatively contact the device. As the guidewire connector is holding the housing stationary with respect to the guidewire, the first plunger end is placed into operative contact with the device with the plunger and housing in a first relative plunger/housing position. The device moves longitudinally. The plunger moves into a second relative plunger/housing position assisted by the operative connection between the first plunger end and the device. The longitudinal difference between the first and second relative plunger/housing positions indicates a distance that the device has moved longitudinally with respect to the guidewire.

Appl. No.:

13/468272

Inventors:

Jason A. Bryan - Avon Lake OH, US

International Classification:

G06F 17/50

US Classification:

703 1

Abstract:

Systems and methods are provided for generating patient specific instruments for use as surgical guides. A region of interest within a body of a patient is scanned to provide a three-dimensional model of the region of interest. A first user is allowed to position a model of a selected implant with the three-dimensional model of the region of interest via a graphical user interface. A patient specific instrument model is generated from a generic patient specific instrument model according to the position of the model of the selected implant within the three-dimensional model of the region of interest and the position of at least one extension of the model that is not visible to the first user. A patient specific instrument is fabricated according to the patient specific instrument model.

International Classification:

G06F 17/50

US Classification:

700 98

Abstract:

A method for providing a synthetic bone model of a subject bone includes providing a file with data representing a three-dimensional subject bone. Manufacturing instructions are generated based upon at least a portion of the data. The manufacturing instructions are transferred to a manufacturing device. A thin-walled outer shell of the synthetic bone model is created directly from the manufacturing instructions using the manufacturing device. The outer shell defines an inner cavity. A filler material is placed within at least a portion of the inner cavity. A synthetic bone model is also disclosed.

International Classification:

A61B 17/16

US Classification:

606 80

Abstract:

A rotary surgical tool includes a driving shaft. A cutting head, connected to the driving shaft, is configured to cut into a surface. Driving means, connected to the driving shaft, rotate the driving shaft and the cutting head. A depth-limiting feature includes an adjustable stud extending from one of the cutting head and the surface toward the other one of the cutting head and the surface. The stud has a protrusion length that is greater than and/or equal to the length of a desired amount of final penetration of the cutting head into the surface. An aperture, provided in the other one of the cutting head and the surface, has an aperture depth that is greater than and/or equal to the desired amount of final penetration of the cutting head into the surface. Interaction between the aperture and the stud limits longitudinal advancement of the cutting head into the surface.

International Classification:

A61F 2/46

US Classification:

606 91

Abstract:

An apparatus for aiding visualization of a prosthetic implant and concurrently landmarking a patient tissue includes a center post having proximal and distal post ends longitudinally separated by a post body. The post body defines a post axis coaxially therewith. An implant emulator embodies a reference feature of a prosthetic implant. The implant emulator is carried on an outer surface of the center post at a predetermined longitudinal spacing from the distal post end. A guiding device is removably attached to the implant emulator. The guiding device includes an attachment structure attached to the implant emulator. A spacing arm is connected to the attachment structure and extends laterally outward from the post axis. A landmark guiding structure is connected to the spacing arm, spaced apart from the center post, and embodies at least one of a location and a trajectory for placement of a landmark.

International Classification:

A61B 5/06

US Classification:

600424

Abstract:

A patient-specific instrument is placed into a predetermined setting position with respect to a patient tissue. A navigation aid is associated in a predetermined origin position with respect to the patient tissue. The navigation aid is zeroed while in the predetermined origin position to record the location and orientation of the navigation aid relative to the patient tissue. An instantaneous position of the zeroed navigation aid is determined with respect to the patient tissue. Feedback is provided to a user on a physical motion needed to bring the instantaneous position of the navigation aid closer to a predetermined desired target position. An indication is made when the instantaneous position of the navigation aid is sufficiently similar to the predetermined desired target position.
