Abstract
Systems and methods are described for implants with composite coatings to promote tissue in-growth and/or on-growth. An implant includes: a substrate; a structured surface formed on at least a portion of the substrate; and a biocompatible coating deposited on at least a fraction of the structured surface. The systems and methods provide advantages in that the implant has good biocompatibility while the biocompatible coating has good strength.
Claims36
An implant, comprising:
- a substrate;
- a structured surface formed on at least a portion of said substrate;
- and
- an osteoconductive coating deposited on at least a fraction of said structured surface,
- wherein said osteoconductive coating is more biocompatible than at least one member selected from the group consisting of said structured surface and said substrate, and
- wherein said structured surface is defined by a material that includes a plurality of particles that are sintered together to form a continuous porous phase.
3 more elements
A composition for an implant, comprising:
- a biocompatible material coated on a structured surface defined by a substrate, wherein said structured surface either
- (i) includes a plurality of undercuts and said biocompatible material coats said plurality of undercuts in said structured surface, or
- (ii) is porous and said biocompatible material coats interconnected pores beneath said structured surface, and
- wherein said structured surface is defined by a material that includes a plurality of particles that are sintered together to form a continuous porous phase.
1 more element
An implant, comprising:
- a substrate;
- a structured surface formed on a portion of said substrate;
- and
- a biocompatible coating deposited on at least a fraction of said structured surface, wherein said portion of said substrate is to be fixed with tissue in-growth and/or on-growth for stability,
- wherein said structured surface either
- (i) includes a plurality of undercuts and said biocompatible material coats said plurality of undercuts in said structured surface, or
- (ii) is porous and said biocompatible material coats interconnected pores beneath said structured surface, and
- wherein said structured surface is defined by a material that includes a plurality of particles that are sintered together to form a continuous porous phase.
