Holder For Resurfacing Head Implant
A holder system for an implantable device, said holder system comprising a first component arranged to act as a clamp and a second component arranged to interact with the first component to prevent movement of said first component when clamped.
METHOD AND APPARATUS FOR PROTECTING MODULAR IMPLANT CONNECTION
Apparatus and methods of protecting modular implant connection portions are provided. A guard includes an outer sidewall and an inner sidewall defining a cavity that covers a modular implant connection portion. The modular implant connection covered with the guard can facilitate test-fitting of other modular implant components and allows reaming of the tissue around the guard.
PROPHYLACTIC BACTERICIDAL MEDICAL DEVICE
A medical implant system is described for inhibiting infection associated with a joint prosthesis implant. An inventive system includes an implant body made of a biocompatible material which has a metal component disposed on an external surface of the implant body. A current is allowed to flow to the metal component, stimulating release of metal ions toxic to microbes, such as bacteria, protozoa, fungi, and viruses. One detailed system is completely surgically implantable in the patient such that no part of the system is external to the patient while the system is in use. In addition, externally controlled devices are provided which allow for modulation of implanted components.
METHOD AND DEVICE FOR REDUCING IMPLANT CONTAMINATION FROM HANDLING
An orthopedic implant has a removable handling cover coupled thereto which includes a thin-walled layer extending over a grasping portion of the outer surface. An outer container can sealingly house the orthopedic implant within a sterile environment and support the orthopedic implant in an orientation that presents the handling cover for grasping. A surgeon can manually grasp, handle and manipulate the implant into an implantation position, and remove the handling cover from the implant during implant surgery, and without the need to directly contact any surface of the orthopedic implant itself. Related methods of providing such an implant assembly and of reducing infection from contamination during implantation surgery are also disclosed.
Taper protection system for orthopedic implants during polishing phases by tribofinishing
A surface protection system comprising a protective sleeve positionable over an orthopedic tool or implant, for example the tapered end of an orthopedioc femoral stem implant to shield the covered surface from exposure to abrasive particles during an automated polishing process is described. The protective sleeve comprises a body having an annular sidewall that extends from a proximal end to a distal end and is composed of a polymeric material. A cavity resides within the body extending through the distal end to a proximal end sidewall positioned perpendicular to the annular sidewall. The protective sleeve further comprises at least one annular recess intermediate at least two annular ridges that reside along an interior surface at the distal end of the sleeve. These series of annular ridges and recesses form a removably tight seal around the exterior surface that minimizes the migration of abrasive polishing particles to the exterior surface of the orthopedic tool or implant. The system further comprises an impactor and extractor tools which facilitate the positioning and removal of the protective sleeve from the surface thereof.
SURGICAL SHOULDER ARTICULATION REPLACEMENT METHOD
This method consists of: a) providing a humeral implant having a hollow stem, said hollow stem being provided with a sharp distal edge, b) impacting the humeral implant in a cancellous bone of a humeral head of a patient, with the sharp distal edge cutting the cancellous bone in the process.
Method and apparatus for protecting modular implant connection
Apparatus and methods of protecting modular implant connection portions are provided. A guard includes an outer sidewall and an inner sidewall defining a cavity that covers a modular implant connection portion. The modular implant connection covered with the guard can facilitate test-fitting of other modular implant components and allows reaming of the tissue around the guard.
SET OF SURGICAL INSTRUMENTS FOR AN ARTIFICIAL HIP JOINT IMPLANT
A set of surgical instruments for an artificial hip joint implant and, more specifically, a set of improved surgical instruments, can be used in direct anterior approach hip replacement surgery and are capable of minimizing damage, such as muscle damage, which may arise during surgery, by resolving problems that existing surgical instruments possess.
DUAL MOBILITY ACETABULAR CUP ASSEMBLY FOR ARTIFICIAL HIP JOINT
An implant for an artificial hip joint and, more specifically, a dual mobility acetabular cup assembly for an artificial hip joint is configured to have improved locking mechanism between a liner and a shell and improved resistance to micromotion and to guide the liner into the shell with proper orientation by providing stable liner-shell fastening structure to the acetabular cup assembly.
ORTHOPAEDIC SURGICAL INSTRUMENT SYSTEM AND METHOD FOR PROTECTING A FEMORAL STEM TAPER
An orthopaedic hip prosthesis system is disclosed. The orthopaedic hip prosthesis system comprises a femoral head component configured to articulate with a natural or prosthetic acetabulum of a patient, the femoral head component having a tapered bore formed therein, a femoral stem component having a tapered trunnion configured to be received in the tapered bore of the femoral head component, and a shell positioned over the tapered trunnion of the femoral stem component. The shell includes a frame extending over the tapered trunnion, and a protective coating applied to the frame and the tapered trunnion. A method of performing an orthopaedic surgery is also disclosed.
