In some embodiments, the term “biocompatible” refers to a material that is capable of functioning or existing in contact with biological fluid, tissue of a living organism, or any combination thereof, with a net beneficial effect on the living organism. Being biocompatible in some embodiments, the article 200 may be useful as a medical device or a portion of a medical device, among other things.
Accordingly, in some embodiments, the article 200 is a medical device. The medical device may comprise an additive manufactured three-dimensional (3D) body and a non-plasma coating layer on at least a portion of a surface of the additive manufactured 3D body. Any of the additive manufactured 3D bodies and non-plasma coating layers of this disclosure may be used herein. For example, in some embodiments, the additive manufactured 3D body has a monolithic structure. In some embodiments, the monolithic structure is not capable of construction by machining.
In some embodiments, the medical device is configured for implantation into a mammal. In some embodiments, the medical device is configured for temporary insertion into a mammal. In some embodiments, the medical device is configured for external use on a mammal. In some embodiments, the additive manufactured 3D body is biocompatible. In some embodiments, the additive manufactured 3D body is a body of the medical device. In some embodiments, the additive manufactured 3D body is a component of the medical device.
In some embodiments, the additive manufactured 3D body is at least one of a balloon, a graft, a stent, a catheter, a shunt, an embolic agent, a pacemaker, a defibrillator, an artificial implant, a prosthetic, a stimulator, a sensor, a wire, a lead, a valve, a plug, a pump, a filter, a mechanical connector, a tube, a plate, a surgical tool, an enclosure, any component thereof, or any combination thereof. In some embodiments, the additive manufactured 3D body is at least one of an angioplasty balloon, a valvuloplasty balloon, a deployment balloon, a pacemaker lead, a prosthetic heart valve, a vascular filter, a vascular plug, an artificial heart valve, an artificial heart, a catheter tip, a suture, a surgical staple, a screw, a nail, a bracket, a pin, a rod, a fixture, a guide wire, a drug pump, a synthetic vessel graft, a vascular graft, a nonvascular graft, a stent graft, a vascular stent, a coronary stent, a peripheral stent, an intraluminal paving stent, an arteriovenous shunt, an aneurysm filler, an implantable pulse generator, an implantable cardiac defibrillator, a cardioverter defibrillator, a spinal stimulator, a brain stimulator, a sacral nerve stimulator, a bone prosthetic, a joint prosthetic, a plastic tubing, a metal tubing, a dental braces, a hearing aid, a bandage, any component thereof, or any combination thereof.
In some embodiments, the additive manufactured 3D body comprises a structural component having an aspect ratio of 2:1 to 1000:1, wherein the aspect ratio is a ratio of two of a width, a depth, a height, or a diameter.
In some embodiments, the additive manufactured 3D body is an article of unitary construction. In some embodiments, the additive manufactured 3D body does not comprise seams. In some embodiments, the additive manufactured 3D body does not comprise braze joints. In some embodiments, the additive manufactured 3D body does not comprise weld joints.
In some embodiments, the non-plasma coating layer is a thermal atomic layer deposition (ALD) coating layer, a chemical vapor deposition (CVD) coating layer, or a solution deposition coating layer.
In some embodiments, the non-plasma coating layer comprises at least one of alumina, yttria, titania, zirconia, tantalum oxide, or any combination thereof.
In some embodiments, the non-plasma coating layer comprises at least one of YOF, YF3, or any combination thereof.
In some embodiments, the non-plasma coating layer comprises at least one of: an oxide of formula MO, wherein M is Ca, Mg, or Be; an oxide of formula M′O2, wherein M′ is a metal; an oxide of formula Re2O3, wherein Re is a rare earth element; an oxide of formula TaxOy, where x is greater than 0 and y is greater than 0; or any combination thereof.
In some embodiments, the non-plasma coating layer comprises at least one of an aluminum-oxy nitride; an yttria-alumina; a silicon oxide; a silicon oxy-nitride; a transition metal oxide; a transition metal oxy-nitride; a rare earth metal oxide; a rare earth metal oxy-nitrides; or any combination thereof.
