Patent number: 10383638Abstract: A computer assisted surgical system for guiding bone cutting operations of an arthroplasty surgery is provided. The computer assisted surgical system includes a cutting guide having a guiding surface for mounting to a bone and a computer. The computer is in communication with the cutting guide and configured to generate a bone model of the first bone without the use of pre-operative bone images, determine a position of an implant model having a bone interface surface on the bone model, determine a position of the cutting guide on the first bone based on the determined position of the implant model on the bone model, and position the guiding surface of the cutting guide to one of a plurality of predetermined cut configurations relative to the bone interface surface.Type: GrantFiled: November 9, 2016Date of Patent: August 20, 2019Assignee: OMNIlife science, Inc.Inventors: Edward J Cheal, George Cipolletti, David L Lasalle, Carl Knobloch, Christopher Plaskos

Patent number: 5976147Abstract: The invention provides a modular system of components used as bone preparation tools and trial prosthesis components. The system includes a trial tibial tray bearing element that mounts upon a prepared tibia, a punch bushing that serves the purpose of a trial tibial stem and helps to guide a tibial punch through the tibia. The trial template element, the punch bushing and the tibial punch can remain in position on the patient's tibia while one or more trial tibial bearing inserts or samples are attached thereto to determine the proper fit and orientation of a prosthesis.Type: GrantFiled: July 11, 1997Date of Patent: November 2, 1999Assignee: Johnson & Johnson Professional, IncInventors: David L. LaSalle, Phillip G. Withee, Mark Denney, George B. Cipolletti

Implantable articles with as-cast macrotextured surface regions and method of manufacturing the same
Patent number: 5897592Abstract: An implantable article having on at least a portion of its exterior surface an integral, as-cast macrotextured surface with macropores having undercut edge profiles. A complex macrotextured surface is provided by forming a casting mold so that the mold has complementary macrotextured surface features formed by three-dimensional printing techniques, and casting a molten metal within or in contact with the casting mold to form the implantable article. In a hybrid process, one or more printed surface mold plates are attached by hand, or in a wax molding process, to a simpler wax preform, and an investment is made in which the plates are incorporated into the investment mold. A casting is then made, with each preform yielding one cast article, and the incorporated plate forming the desired surface macrotexture on a region of the cast article.Type: GrantFiled: April 29, 1997Date of Patent: April 27, 1999Assignee: Johnson & Johnson Professional, Inc.Inventors: Salvatore Caldarise, Richard P. Manginelli, David L. LaSalle, Timothy M. Flynn -
Bone prostheses with direct cast macrotextured surface regions and method for manufacturing the same
Patent number: 5713410Abstract: An implantable article having on at least a portion of its exterior surface an integral, as-cast macrotextured surface having pores with undercut edge profiles is provided. The integral, as-cast macrotextured surface is able to be formed on the implantable articles by a modified casting process. As part of a casting process, positive models of the articles to be cast, or parts thereof, are formed by stereolithographic techniques. Cavities or molds, representing negative images of the articles to be cast, are then formed by encasing one or more models in a refractory material. The positive models are then extracted by heating and thus melting the material from which they are made. Thereafter, molten casting material can be poured into the resulting mold to obtain the implantable articles.Type: GrantFiled: June 1, 1995Date of Patent: February 3, 1998Assignee: Johnson & Johnson Professional, Inc.Inventors: David L. LaSalle, Timothy M. Flynn, Salvatore Caldarise, Richard P. Manginelli -

Patent number: 5676668Abstract: An improved femoral locating device and system is provided including an angularly adjustable locking alignment portion for appropriately aligning the posterior end of the locator. Another feature of the system provides a cutting block moveable from distal to proximal or proximal to distal to alter the thickness of the cut and holding it securely once the thickness of the cut is determined. Finally, another feature of the system includes the ability to raise and lower the cutting block without changing the valgus angle.Type: GrantFiled: February 20, 1996Date of Patent: October 14, 1997Assignee: Johnson & Johnson Professional, Inc.Inventors: Diana McCue, Richard Techiera, Gary P. Trottier, Donald Marcoccio, David L. LaSalle
