International Classification:

C08K003/34

US Classification:

524445000

Abstract:

There is described a composite composition comprising a layered mineral and at least one polymer precursor which is substantially miscible therewith; characterised in that: (i) the composition and/or polymer precursor are polymerisible by radiation to form a polymeric composition; and/or (ii) the polymer precursor comprises a polymer obtained and/or obtainable by polymerisation with radiation. Further described are composite compositions comprising a layered mineral and intercalated therein at least one polymer which is further polymerisable by radiation to form a polymeric network, such as a polymeric coating. Preferred minerals are nanoclays such a montmorillonite in which the counter cation comprises a radiation curable organo functional group covalently bonded thereto (e.g. an acrylate functional onium ion). Processes for making the composites are also described.

International Classification:

A61M 2900

US Classification:

606191

Abstract:

A highly elastic, adjustable helical coil stent (10) has a helical coil (20) which can be contracted around a small diameter catheter (12) for percutaneous insertion into a human body and then can be remotely expanded back to its original shape when positioned at the desired location within the human body. The helical coil is preferably formed of a metal alloy (25) with high elasticity, such as superelastic Nitinol, encased within an elastomer (26). The helical coil is affixed at its distal end to a catheter and affixed at its proximal end to a control tube (30). By rotating the control tube in one direction relative to the catheter (e. g. , clockwise), the helical coil contracts and by rotating the control tube in the opposite direction (e. g. , counterclockwise), the helical coil expands. The adjustable helical coil stent of the present invention is particularly useful for total or partial heart assist during heart bypass procedures.

Abstract:

Drug-loaded microbead compositions including a plurality of individual microbeads of a biodegradable material, a plurality of individual vesicular agents, a first therapeutic agent, and a second therapeutic agent different from the first therapeutic agent. The vesicular agents include at least one lipid bilayer surrounding a vesicular core. The first therapeutic agent is associated with the individual vesicular agents. For example, the first therapeutic agent may be contained within the individual vesicular agents or may be associated with the individual vesicular agents by ionic or non-covalent interaction. The second therapeutic agent is different from the first therapeutic agent and contained within the individual microbeads or associated with the individual microbeads through ionic or non-covalent interaction. The second therapeutic agent may or may not be associated with the individual vesicular agents. Drug-loaded biodegradable microbead compositions include microbeads of biodegradable material and a therapeutic agent associated with N the microbeads.

Abstract:

Medical devices such as stents, stent grafts, and balloon catheters include a coating layer applied over a modified exterior surface of the medical device. The modified exterior surface comprises an exterior surface of the medical device subjected to a surface modification that decreases a surface free energy of the exterior surface before application of the coating layer an exterior surface. The coating layer comprises a hydrophobic therapeutic agent and at least one additive. The modified exterior surface may affect the release kinetics of the drug from the device, the crystallinity of the drug layer, the surface morphology of the coating and particle shape, or the particle size of drug of a therapeutic layer in the coating layer. For example, the effects caused by the modified exterior surface may increase the retention time and amount of therapeutic agent in tissue.

Abstract:

Drug-loaded microbead compositions include microbeads of a water-swellable polymer material and a complex of a carrier and a therapeutic agent chemically bonded to the carrier. The complex is embedded in the polymer material. Methods for preparing the drug-loaded microbead compositions and embolization compositions include loading a therapeutic agent into a water-swellable polymer material to form microbeads, then removing water from the microbeads. Additional drug-loaded microbead compositions include microbeads of a biodegradable material, vesicular agents, a first therapeutic agent associated with the vesicular agents, and a second therapeutic agent different from the first therapeutic agent. The vesicular agents include a lipid bilayer surrounding a vesicular core. The second therapeutic agent is contained within the microbeads or associated with the microbeads through ionic or non-covalent interaction and may or may not be associated with the vesicular agents. Drug-loaded biodegradable microbead compositions include microbeads of biodegradable material and a therapeutic agent.
