Patent number: 9023050Abstract: A patellar 3-D guidance tool includes a template. The template includes at least one contact surface for engaging a surface of the patella. The at least one contact surface substantially conforms with the surface associated with the patellar. At least one guide aperture directs movement of a surgical instrument, wherein the shape and/or position of the guide aperture is based, at least in part, on three or more anatomic reference points associated with the patellar.Type: GrantFiled: May 11, 2010Date of Patent: May 5, 2015Assignee: ConforMIS, Inc.Inventors: Philipp Lang, Wolfgang Fitz, Raymond A. Bojarski, Daniel Steines, Albert G. Burdulis, Jr., Rene Vargas-Voracek

Publication number: 20150099936Abstract: Devices, systems and methods are provided for accessing a target location in the body of a patient, particularly within the epidural space. A system includes a sheath and a sheath support supporting the sheath to reduce or avoid kinking. The sheath support closely fits within the sheath while maintaining free sliding therein. The sheath support has a non-compliant outer diameter maintaining the inner diameter of the sheath and preventing the sheath walls from collapsing into a kink, particularly during low radius bends that may occur during delivery. The sheath support may include a distal tip configured to resist retraction into the sheath until a threshold force is reached which causes the distal tip to at least partially retract into the lumen of the sheath. Likewise, the distal tip may be fully retractable through the sheath so that the sheath support is removable from the proximal end of the sheath.Type: ApplicationFiled: October 9, 2014Publication date: April 9, 2015Inventors: Albert G. BURDULIS, Evan S. VANDENBRINK, Fred I. LINKER

Patent number: 8882847Abstract: Disclosed herein are methods and devices for repairing articular surfaces in a knee joint. The articular surface repairs are customizable or highly selectable for each patient and geared toward providing optimal fit and function. Kits are also provided to enable customized repairs to be performed.Type: GrantFiled: November 24, 2004Date of Patent: November 11, 2014Assignee: ConforMIS, Inc.Inventors: Albert G. Burdulis, Jr., Wolfgang Fitz, Philipp Lang, Daniel Steines, Konstantinos Tsougarakis, Rene Vargas-Voracek, Hacene Bouadi, David Miller

Publication number: 20140257240Abstract: Articulable introducer sheaths and related methods and systems for accessing various surgical sites are disclosed. An introducer sheath comprises a tubular body and a filament. The tubular body has a proximal portion, a distal portion, and a central lumen. The filament is constrained on or within at least a portion of the proximal portion and unconstrained over at least a portion of the distal portion. The distal end of the filament is held or attached near a distal end of the tubular body so that advancement of the filament relative to the tubular body causes the unconstrained portion to bow out or extend radially outward, such as to engage a body tissue so as to steer the tubular body when the tubular body has been introduced into a surgical site, such as an epidural space. A surgical tool or medical implant can then be advanced through the sheath.Type: ApplicationFiled: March 8, 2013Publication date: September 11, 2014Applicant: Spinal Modulation, Inc.Inventor: Albert G. Burdulis

Patent number: 8657827Abstract: Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.Type: GrantFiled: November 22, 2011Date of Patent: February 25, 2014Assignee: ConforMIS, Inc.Inventors: Wolfgang Fitz, Philipp Lang, Raymond A. Bojarski, Daniel Steines, Albert G. Burdulis, Jr., Rene Vargas-Voracek

Publication number: 20130345783Abstract: The present invention provides devices, systems and methods for anchoring medical devices to hard tissues, such as bones or bony structures, particularly vertebrae. By anchoring these medical devices directly to the surrounding hard tissue, the devices are anchored closer to the source of treatment. This provides additional stability and reduces migration of the device at the treatment site. Also, by attaching to hard tissue rather than soft tissue, a stronger attachment is often able to be made.Type: ApplicationFiled: August 23, 2013Publication date: December 26, 2013Inventor: Albert G. BURDULIS

Publication number: 20120245699Abstract: A mobile bearing implant includes a first component. The first component includes a bone facing surface for engaging one of a substantially uncut articular cartilage surface and a substantially uncut subchondral bone surface. The bone facing surface substantially matches the one of the articular cartilage surface and the subchondral bone surface. The mobile bearing implant further includes an external surface. A bearing component has a first surface for slidingly engaging the external surface of the first component, and a second surface for engaging at least one of a second component, bone, and cartilage.Type: ApplicationFiled: March 15, 2012Publication date: September 27, 2012Applicant: ConforMIS, Inc.Inventors: Philipp LANG, Albert G.
