More particularly, the present invention relates to an implant for in-vivo insertion, wherein the porosity of a porous coating layer formed on the surface of the implant, thus increasing the bone adhesion of the implant into pores, the adhesivity between the implant and the porous coating layer and the adhesivity between particles in the porous coating layer, wherein vertically-curved pores each having a radius of 100˜300 μm are formed in the porous coating layer to increase the adhesivity of the implant to the bone growing into the pores, thus increasing bone adhesion, and wherein the ratio of interconnected pores in the porous coating layer is increased, and thus bones growing into the pores are interconnected, thereby increasing the adhesivity between the implant and the bones. | 10-24-2013 |
20140025181 | METALLIC STRUCTURES HAVING POROUS REGIONS FROM IMAGED BONE AT PRE-DEFINED ANATOMIC LOCATIONS - A method of forming an implant having a porous region replicated from scanned bone, the method comprising imaging bone with a high resolution digital scanner to generate a three-dimensional design model of the bone; removing a three-dimensional section from the design model; fabricating a porous region on a digital representation of the implant by replacing a solid portion of the digital implant with the section removed from the digital representation; and using an additive manufacturing technique to create a physical implant including the fabricated porous region. | 01-23-2014 |
20140188244 | PYROLYTIC CARBON IMPLANTS WITH POROUS FIXATION COMPONENT AND METHODS OF MAKING THE SAME - An orthopedic implant including an articulation portion having a pyrolytic carbon bearing surface and a porous bone on- or in-growth structure, and methods of making the same. | 07-03-2014 |
20140343687 | Substrate with a Structured Surface and Methods for the Production Thereof, and Methods for Determining the Wetting Properties Thereof - An implant includes a microstructured hyperhydrophilic surface with protrusions and depressions in which a spacing between the protrusions as a statistical mean is in a range of 1 to 100 μm and a profile height of the protrusions and depressions as a statistical mean is in the range of 1 to 80 μm. | 11-20-2014 |
20150032222 | POROUS METAL IMPLANTS WITH BONE CEMENT - An orthopaedic implant for filling a bone void and a method of using the same. The orthopaedic implant comprises an open porous metal portion and a bone cement portion. At a first surface region, the open porous metal portion facilitates hone and/or soft tissue ingrowth into the pores of the first surface region of the open porous metal. At a second surface region, the open porous metal facilitates reception of the bone cement into the pores of the second surface region of the open porous metal. The open porous metal portion of the orthopaedic implant may also be formed of a plurality of porous metal fragments aggregated together with the cement portion of the orthopaedic implant. Additionally, the orthopaedic implant may be pliable and thereby capable of being molded to the shape of a void in a bone. | 01-29-2015 |
20150289979 | BONE IMPLANT MADE OF AT LEAST TWO DIFFERENT ABSORBABLE AND BIODEGRADABLE MATERIALS ADAPTED TO BE COMBINED AS HYBRID OR COMPOSITE MATERIAL - A bone implant includes a support structure made of metal ahoy and includes a biodegradable and absorbable protective structure, the protective structure being arranged at and/or on the support structure so that the support structure is protected from contacting any aggressive body fluid in a position anchored in a bone of an individual such as a mammal, wherein the support structure is surrounded by and interspersed with the protective structure. | 10-15-2015 |
