PACKAGING ASSEMBLIES FOR SURGICAL STAPLE CARTRIDGES CONTAINING BIOABSORBABLE STAPLES
Packaging assemblies for storing and shipping surgical staple cartridges containing bio-absorbable staples.
Attenuation of encrustation of medical devices using coatings of inorganic fullerene-like nanoparticles
A new approach is presented to reduce encrustation of catheters by the application of nanoparticles. It is demonstrated that the negatively surface charged nanoparticles produce coating films comprised of long-range domains in which the nanoparticles are self-assembled into a mosaic-like order, showing a relatively small tendency to agglomerate.
Implantable medical product with permanently negatively charged surface
An entirely or partially implantable medical product with a negatively charged surface for repulsing bacteria has a superficially bonded substance with a permanently negative excess charge, which substance is inert against cells of the human body and the bacteria contained therein.
SELF-FUELED PARTICLES FOR PROPULSION THROUGH FLOWING AQUEOUS FLUIDS
A simple, self-propelling particle system is disclosed that can deliver a cargo through flowing aqueous solutions. This disclosure provides a non-aqueous composition comprising: (i) particles formed of a carbonate salt and having an average diameter of about 100 μm or less; and (ii) an acid in solid form. The particles may be associated with a cargo molecule or particle. In mouse models of severe hemorrhage, the propelled particles are able to deliver a procoagulant enzyme and halt bleeding.

METHODS OF USING WATER-SOLUBLE INORGANIC COMPOUNDS FOR IMPLANTS
A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.
BIOMEDICAL DEVICE INCLUDING ENCAPSULATION
A biomedical device including an energy source, an electro-active device operatively connected to the energy source, circuitry configured to control operation of the electro-active device, at least one barrier layer including at least one inorganic material surrounding the energy source, electro-active device and circuitry, and at least one molded layer surrounding the at least one barrier layer. A method for encapsulating electronic components of an electro-active biomedical device in a protective envelope containing a barrier layer including at least one inorganic compound, and a molded polymer overcoat.
Ultrahigh ductility, novel Mg—Li based alloys for biomedical applications
The invention relates to compositions including magnesium-lithium alloys containing various alloying elements suitable for medical implant devices. The devices may be constructed of the compositions or have applied thereto a coating formed therefrom. Within the structure of the magnesium-lithium alloy, there is a co-existence of alpha and beta phases. The invention also relates to methods of preparing the magnesium-lithium alloys and articles, such as medical implant devices, for use in medical applications, such as but not limited to, orthopedic, dental, craniofacial and cardiovascular surgery.
Coatings for surgical instruments
A coated medical instrument can include a first layer bonded to a metal substrate surface of a medical instrument, a second layer bonded to the first layer, and a third layer disposed on the second layer, The first layer comprises chromium (Cr), hafnium (Hf), titanium (Ti), and/or niobium (Nb). The second layer comprises a nitride, oxide, carbide, carbonitride, or boride of chromium (Cr), hafnium (Hf), niobium (Nb), tungsten (W), titanium (Ti), aluminum (Al), zirconium (Zr), and/or silicon (Si). The third layer comprises a nitride, oxide, carbide, boride, oxynitride, oxycarbide, or oxycarbonitride of chromium (Cr), hafnium (Hf), niobium (Nb), tungsten (W), titanium (Ti), aluminum (Al), zirconium (Zr), and/or silicon (Si). Methods for making coated medical instruments are also disclosed herein.
