MRI-visible hydrophobic copolymer
The invention relates to a hydrophobic thermoplastic copolymer which is in particular of use for manufacturing and/or coating medical devices, in particular implantable medical devices, characterized in that it is obtained by copolymerization, and in that it comprises at least one first monomer unit and at least one second monomer unit onto which is grafted a paramagnetic-ion-chelating ligand which can complex with such a paramagnetic ion or a paramagnetic-ion-chelating ligand which is complexed with such a paramagnetic ion, wherein the second monomer unit is grafted in sufficient amount for the copolymer to be visible in magnetic resonance imaging when it is complexed with said paramagnetic ion. The invention also relates to a method for obtaining said hydrophobic thermoplastic copolymer.
USE OF PEBA HAVING LONG BLOCKS FOR THE MANUFACTURE OF ALL OR PART OF A CATHETER
A copolymer containing polyether blocks and polyamide blocks for manufacturing an inflatable catheter element, such as a catheter balloon, with improved bursting strength, in which said copolymer has the following characteristics: number-average molecular mass of the PE blocks greater than 500 g/mol, and number-average molecular mass of the PA blocks greater than 10 000 g/mol.
Collagen peptide-based medicament compositions and devices and methods of production and use thereof
The present invention is in the fields of medicinal chemistry, biotechnology and pharmaceuticals. The invention provides compositions comprising one or more collagen mimetic peptides, optionally attached to one or more therapeutic compounds or one or more imaging compounds, for use in methods of treating, preventing, ameliorating, curing and diagnosing certain diseases and physical disorders in humans and veterinary animals, as well as methods of manufacturing such composition. The invention also provides medical devices comprising one or more such compositions of the invention. The invention also provides methods of use of such compositions and devices in treating and diagnosing certain diseases and physical disorders in humans and veterinary animals, including ocular diseases or disorders, skin diseases or disorders, certain cancers, particularly intraluminal cancers, gastrointestinal diseases or disorders, genitourinary tract diseases or disorders, fibrotic diseases/disorders and rheumatic diseases/disorders.
High temperature melting
The present invention relates to methods for making wear and oxidation resistant polymeric materials by high temperature melting. The invention also provides methods of making medical implants containing cross-linked antioxidant-containing tough and ductile polymers and materials used therewith also are provided.
Catheters with high-purity fluoropolymer additives
The present invention provides catheter compositions that provide anti-thrombogenic properties while not adversely impacting mechanical properties. All embodiments of the present invention comprise a catheter that comprises a fluoropolymer additive with specific compositions and/or purity levels.
MEDICAL ELONGATED BODY AND BALLOON CATHETER
A medical elongated body or a balloon catheter that include a catheter main body, a tubular body, and a distal member at a distal end of the tubular body. The distal member is more flexible than the tubular body. The distal end of the tubular body is joined to the distal member at a joint portion. The tubular body includes an outer layer and an inner layer disposed inside of the outer layer in the radial direction of the tubular body. The material of the inner layer possesses better fusing properties with respect to the distal member than the fusing properties of the outer layer material with respect to the distal member material. The inner layer is interposed between the distal member and the outer layer by extending between the distal member and the outer layer at the joint portion.
Silicone rubber-based curable composition, method for producing silicone rubber, silicone rubber, molded article, and tube for medical use
The present invention provides a silicone rubber-based curable composition with which a silicone rubber having excellent tensile strength and tear strength is obtained, a method for producing a silicone rubber using the silicone rubber-based curable composition, a silicone rubber, a molded article using the silicone rubber, and a tube for medical use formed from the molded article. The silicone rubber-based curable composition of the present invention is characterized in that it includes a vinyl group-containing organopolysiloxane (A), an organohydrogen polysiloxane (B), silica particles (C), a silane coupling agent (D), and platinum or a platinum compound (E).
Antimicrobial Coatings
Described are coatings for medical devices and methods of forming same.
Expandable introducer sheath
One embodiment is directed to a system for deploying a device to a distal location across a vessel, comprising an elongate introducer sheath tubing member comprising open-cell fibrous wall material defining a lumen therethrough, wherein in a collapsed configuration the sheath has a first cross-sectional outer diameter and a first lumen inner diameter, and in an expanded configuration, the sheath has a second cross-sectional outer diameter and a second lumen inner diameter; and a substantially non-porous expandable layer coupled to a proximal portion of sheath and configured to prevent fluids present in the lumen from crossing the fibrous wall material.
MEDICAL DEVICE WITH SUBSTRATE COMPRISING NATURAL FIBRES
A medical device for insertion into a natural or artificial body opening, such as a urinary catheter is described. The medical device comprises a substrate having a wall enclosing an internal cavity that forms a tubular body. The wall extends between a proximal insertion end and a distal rearward end. The wall comprises at least 30 wt % of natural fibers, such as cellulose fibers. One example medical device is, at least to a large extent, made of paper.
