A composite metal porous body according to an aspect of the present invention has a framework of a three-dimensional network structure. The framework includes a porous base material and a metal film coated on the surface of the porous base material. The metal film contains titanium metal or titanium alloy as the main component.

Implantable materials having defined patterns of affinity regions for binding endothelial cells and providing for directed endothelial cell migration across the surface of the material. The affinity regions include photochemically altered regions of a material surface and physical members patterned on the material surface that exhibit a greater affinity for endothelial cell binding and migration than the remaining regions of the material surface.

The invention entails metal alloy mono and poly-filament wire reinforced carbon fiber plating system for the fixation of skeletal fractures and osteotomies. Current fracture fixation plating systems are metal alloy designs that block the field of vision of the fracture during radiographic evaluation. Carbon fiber and mono and poly-filament wire plating systems reduce the weight and thickness as compared to the current plating designs while permitting direct visualization of the fracture site during the healing process. The benefits of the plating design contribute to the satisfaction of the patient and reduce disruption to the surrounding soft tissue structures. An embodiment of the plating system entails layered sheets of carbon fiber with an infrastructural framework of metal alloy mono and poly-filament wire for added strength and durability of the plate. This system can be utilized for all types of skeletal fracture and osteotomy fixation as well as fields of mechanical, aerospace, and structural engineering where durable lightweight, high strength materials are required.

The present invention relates to a resorbable implant material made of magnesium or magnesium alloy and to a process for the production thereof. A disadvantage of the known resorbable implants is that their resorption has hitherto only been trackable using x-ray or CT examinations. The invention provides a resorbable implant material comprising homogeneously distributed fluorescent nanodiamonds in a matrix of magnesium or a magnesium alloy. Fluorescent nanodiamonds are biologically nonhazardous and provide a stable emission in the near infrared range due to nitrogen-vacancy centers (NV centres). This allows detection of the implant material in the blood plasma of the patient.

The resorbable implant material according to the invention is produced by a process wherein magnesium or a magnesium alloy is melted, nanodiamonds are added to the melt and the melt of magnesium or a magnesium alloy provided with nanodiamonds is subjected to an ultrasound treatment.

Microbially-resistant materials are disclosed and described, along with devices, surfaces, and associated methods. Such materials can be coated onto device surfaces, system surfaces, structures, and the like.

An absorbable implant material comprising homogeneously distributed Fe-doped nanodiamonds in a matrix composed of magnesium or a magnesium alloy and a method for the production thereof is provided. The absorbable implant material is produced by a method in which magnesium or a magnesium alloy is melted, Fe-doped nanodiamonds are added to the melt, and the melt composed of magnesium or a magnesium alloy that has been provided with Fe-doped nanodiamonds is subjected to an ultrasound treatment.

An implantable medical device includes an elongated tubular body having opposed proximal and distal end portions and defining a longitudinal axis. The elongated tubular body includes an interior lumen extending therethrough. A plurality of axially spaced apart electrode rings are operatively associated with the distal end portion of the tubular body. The electrode rings are formed from at least one of bismuth or pyrolytic graphite. A plurality of electrical conductors extend through the interior lumen of the tubular body. Each of the electrical conductors is operatively associated with a respective one of the plurality of electrode rings. The electrical conductors are formed from at least one of bismuth or carbon fiber.

In a method for manufacturing a component containing an iron alloy material, a pulverulent pre-alloy is provided. The pre-alloy comprises, in wt. %, 0.01 to 1% C, 0.0.01 to 30% Mn, 6% Al, and 0.05 to 6.0% Si, the remainder being Fe and usual contaminants. The pulverulent pre-alloy is mixed with at least one of elementary Ag powder, elementary Au powder, elementary Pd powder and elementary Pt powder so as to produce a powder mixture containing 0.1 to 20% of at least one of Ag, Au, Pd and Pt. The powder mixture is applied onto a carrier (16) by means of a powder application device (14). Electromagnetic or particle radiation is selectively irradiated onto the powder mixture applied onto the carrier (16) by means of an irradiation device (18) so as to generate a component from the powder mixture by an additive layer construction method.

Systems, devices, methods, and compositions are described for providing an actively controllable implant configured to, for example, monitor, treat, or prevent microbial growth or adherence to the implant.
