Embodiment Construction

[0058] As used herein, "a" and "an" include both the singular and the plural and mean one or more than one. Generally herein, the singular includes the plural, and the plural includes the singular, unless otherwise indicated or otherwise obvious from context.

[0059] As used herein, the term "network" refers to a structure having an interconnected network of openings defined by a continuous arrangement of struts and nodes. The network can generally be described as a foam or sponge-like form with open cells.

[0060] As used herein, the term "pillar" refers to material boundaries between fenestrations in an open-celled network.

[0061] As used herein, the term "node" refers to the intersection location of a number of struts in a network of open cells.

[0062] As used herein, the term "terminal strut" means a strut associated with only one junction. In a typical monolithic network, terminal struts are only present in the surface of the monolith where the structure has been...

Abstract

A composition, a medical implant constructed from the composition, and a method of making the composition are described. The composition comprises a porous-coated substrate, the porous coating comprising a reticulated particle coating, the coating being formed by fusing the reticulated particle to the surface, preferably by sintering.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application Serial No. 60 / 942,523, filed June 7, 2007. technical field [0003] The present invention relates to new porous structures comprising porous coatings of sintered reticulated particles. The new structure is useful in any application where the porous structure is useful, but will be useful as part of a medical implant material that will promote tissue ingrowth into the implant, among other things. Background of the invention [0004] Traditional tissue ingrowth techniques have been relatively successful in helping to restore form and function in a variety of medical implant applications. However, in some patients, conditions or situations, they are not an ideal solution. Conventional technologies have tended to have relatively low porosity, low long-term strength, high stiffness, poor initial stability, or other problems that limit their suitability for a...
