SYSTEMS AND METHODS FOR AUTOMATED IMAGE RECOGNITION OF IMPLANTS AND COMPOSITIONS WITH LONG-LASTING ECHOGENICITY
Systems and methods for imaging an object that are capable of capturing an image or images of the object using an imaging modality, automatically detecting and analyzing the image or images by way of converting the image or images to at least one binary image, and analyzing the at least one binary image to extract and/or segment regions-of-interest (ROIs) from the at least one binary image. The object can be or include an implantation, occlusion, medical device, body lumen, tissue, organ, duct, and/or vessel. The imaging modality can be or include X-ray, CT, MRI, PET, and/or ultrasound, or any combination thereof. Also included are compositions of soft, implantable materials with one or more carbon-based material, nanomaterial, and/or allotrope present in an amount sufficient as an ultrasound contrast agent effective for days, months, or years and which compositions are useful in the automated imaging methods of the invention.
Laser Markable Medical Devices
Medical devices comprise a polymeric body comprising: a base polymeric formulation comprising at least a polymer or co-polymer of propylene; and an additive comprising a copolymer having a polypropylene backbone and hybrid micromolecule side-chains based on organo-functional silanes (PP-g-XSiOA) in the presence of a co-agent, for example, difunctional metallic diacrylate monomers, where X is an organic group or an organo-functional group, and A is a metal, an inorganic oxide, an inorganic hydroxide, or any other inorganic material. X may be derived from a compound selected from the group consisting of epoxy, amino, acrylate, methacryloxy, and vinyl; and A is selected from the group consisting of: silicon, (Si), aluminum (Al), iron (Fe), titanium (Ti), silver (Ag), zinc (Zn), nickel (Ni), calcium (Ca), copper (Cu), tin (Sn); oxides thereof; hydroxides thereof; and mixtures of the foregoing. Optionally, inorganic fillers may be included. The medical devices are laser markable.
Local thermal actuation of material surfaces via micro- and nanowire heating for the prevention of cellular attachment and biological fouling
The invention relates in various embodiments to a composite useful as e.g. a medical implant device, and a method of treating fouling, including biofouling as may occur on an implant. The composite comprises a matrix phase and a patterned phase that comprises an energetically activatable wire intermixed with the matrix phase, the wire when energetically activated, which includes thermal activation, causes modification of at least a portion of the matrix phase to treat fouling that might otherwise occur. The method of treating biofouling may be practiced on a patent while the medical implant of the invention is in situ.
COMPOSITE IMPLANT COATING
A coating layer, for example PEEK or titanium foil, shields a bone implant surface from wearing interactions with surfaces of bone and/or other implants. The coating prevents shedding particles which are difficult to distinguish from evidence of potentially dangerous conditions, for example, microorganism contamination and/or degenerating tissue. Methods and structures for securing a coating layer are described. Other uses and implementations of coating layers are described.
