BIODEGRADABLE IRON-CONTAINING COMPOSITIONS, METHODS OF PREPARING AND APPLICATIONS THEREFOR
The invention relates to biodegradable iron alloy-containing compositions for use in preparing medical devices. In addition, biodegradable crystalline and amorphous compositions of the invention exhibit properties that make them suitable for use as medical devices for implantation into a body of a patient. The compositions include elemental iron and one or more elements selected from manganese, magnesium, zirconium, zinc and calcium. The compositions can be prepared using a high energy milling technique. The resulting compositions and the devices formed therefrom are useful in various surgical procedures, such as but not limited to orthopedic, craniofacial and cardiovascular.
Embolic implant and method of use
A parent artery occlusion (PAO) device which provides for immediate occlusion of a cerebral artery to isolate a defect. The PAO device includes a self-expanding wire-frame prolate structure which is partially covered with an ePTFE membrane.
Implant and kit for treating a bone defect
An implant for treating a bone defect wherein the implant comprises osteoconductive supporting bodies and an insertion aid. The insertion aid is designed for insertion of the osteoconductive supporting bodies into a bone defect and for holding together the osteoconductive supporting bodies. Also disclosed is a kit comprised of an implant for treating a bone defect.
Anatomical wedge implant
An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

Ultrasonic surgical blades
An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

Surgical cutting device with shield drive mechanism
Devices for removing implanted objects from body vessels are provided. A device includes a sheath assembly having a cutting tip. The cutting tip includes a cutting surface that is adapted to cut tissue coupled to an implanted object as the cutting tip rotates. The sheath assembly further includes an outer shield carried outside of the cutting tip. The outer shield includes a distal opening, and the outer shield is translatable relative to the cutting tip from a first position to a second position and vice versa. In the first position the cutting surface of the cutting tip is disposed within the outer shield, and in the second position the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield.
Medical device with drug-eluting coating on modified device surface
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.
Azobenzene polymer network, and uses thereof for biofilm removal and control over cell attachment
Disclosed methods include formulating azobenzene-based polymer networks to induce a modulus change in a highly crosslinked polymer, in vivo, with no external heat requirement and using a benign light as the source of stimuli. A modulus change can be achieved via a coating on the substrate and within the bulk of the substrate via photoexposure. The azobenzene-based polymer network can be formed as a coating or in the bulk of a material from either a glassy composition comprising methyl methacrylate (MMA), poly (methyl methacrylate) (PMMA), and triethylene glycol dimethacrylate (TEGDMA) or a soft material comprising of long-chain difunctional acrylates. The disclosed technology also includes methods of biofilm disruption and removal from the surface of a substrate, and includes methods of inhibiting biofilm growth and cell attachment to a substrate.
