20080208198 | Osteochondral Implant Procedure and Device - A surgical procedure according to which a slotted film is positioned over an area of a bone to be milled; and a portion of a milling assembly is inserted in the defect, with another portion of the assembly extending through one of the slots so that the slot can be used as a guide to mill the bone. | 08-28-2008 |
20080228072 | Foreign Body Identifier - A surgical instrument for the presence and/or location of a foreign body is disclosed. The surgical instrument is hand-held. In some embodiments, the surgical instrument includes transducers adapted for emitting and/or receiving signals. In such embodiments, the surgical instrument utilizes pulse-echo measurements to determine characteristics and/or location of the foreign body. In other embodiments, the surgical instrument includes a measurement circuit for detecting the presence and/or location of a foreign body by a change in the characteristics of the measurement circuit. The surgical instrument may be utilized to determine such things as the size of a foreign body, the orientation of a foreign body with respect to patient anatomy and/or another foreign body, and whether the foreign body has been completely removed. | 09-18-2008 |
20080262347 | METHOD AND APPARATUS FOR MONITORING INTEGRITY OF AN IMPLANTED DEVICE - A system for detecting the integrity of a previously implanted prosthetic device may include a detector including a sensor configured to detect signals from the implant and securing means for securing the sensor in a sensing position relative to the implantable device. The system also may include a power source configured to provide power to the sensor and a computation means for processing data communicated by the detector and for displaying the processed data for diagnosing. | 10-23-2008 |
20090118750 | Chisel System for Osteochondral Implants and A Surgical Procedure Involving Same - A chisel system for harvesting an implantable graft from an area of a human having a cartilage overlying a condyle, according to which a module is provided that has one end connected to a handle. A cutting surface is formed at the other end of the module that cuts through the cartilage and condyle. | 05-07-2009 |
20100198223 | Osteochondral Implant Fixation Method - A surgical procedure and a device used in the procedure according to which one end portion of a guide rod is inserted into the condyle of a damaged area of a human. The rod is used as a guide for a drill bit and a chisel to cut an opening in the condyle. | 08-05-2010 |
20100268261 | OSTEOCHONDRAL IMPLANT FIXATION PROCEDURE AND BONE DILATOR USED IN SAME - A surgical procedure for implanting a graft according to which a dilator is inserted in a recipient opening and the graft is inserted in the dilator to cause outward expansion of the dilator into engagement with the portion of a bone surrounding the opening. After the dilator is removed from the opening, the bone surrounding the opening collapses around the graft to secure the graft in the opening. | 10-21-2010 |
20110035025 | OSTEOCHONDRAL IMPLANT PROCEDURE - A surgical procedure for preparing a damaged area of a human knee to receive at least one graft, according to which a moldable material is positioned over the damaged area and removed after it hardens. The mold is used as a template to determine the number and/or a dimension of the openings to be formed in the damaged area for receiving corresponding grafts. | 02-10-2011 |
20110160587 | VOLUMETRIC MEASUREMENT AND VISUAL FEEDBACK OF TISSUES - Apparatus and methods for assessing tissue characteristics such as the dimensions and volume of an osteolytic lesion are disclosed. The apparatus may utilize ultrasound to provide visual and volumetric feedback related to a lesion or other tissue. Further the apparatus may be utilized to determine whether the lesion has been completely removed and filled with the appropriate amount of graft material. | 06-30-2011 |
20110208193 | System and Method of Harvesting Osteochondral Plugs - A method is disclosed and can include engaging a harvest guide with bony tissue and placing a cutting device within the harvest guide. The harvest guide can maintain the cutting device substantially perpendicular to a tangent through a point on the bony tissue aligned with the cutting device. The cutting device can be an osteochondral chisel, a trephine, or a combination thereof. | 08-25-2011 |
20120253323 | ROTATIONALLY DRIVEN SURGICAL TOOL ASSEMBLY AND METHOD - A surgical tool assembly typically includes a drive unit and a surgical tool. The drive unit includes a female drive recess for receiving the proximal end of the surgical tool. A guard is disposed in front of the drive recess and acts as a filter to limit the possible surgical tools that may be mated with the drive unit. The guard includes a non-circular filter opening with a minimum cross dimension that is larger than a minimum cross dimension of the drive recess, but smaller than the maximum cross dimension of the drive recess. Proper surgical tools include a non-round keying section that is configured to fit through the guard opening in at least one orientation. The guard is spaced sufficiently forward relative to the drive recess so that only properly keyed surgical tools may be mated with the drive recess. | 10-04-2012 |
