摘要:
An occlusive, pressure-reducing wound dressing with a multi-layer laminate construction providing one easy-to-apply dressing. The occlusive pressure-reducing dressing includes an occlusive, wound-contacting layer made of a biologically compatible polymer. A pressure-reducing layer is joined at a bottom surface to the occlusive layer. The pressure-reducing layer is comprised of a soft, air-containing material such as a foam or an air-entrapping film which has a top surface shaped to provide a progressive rate of resistance to compressive force applied to the pressure-reducing layer and which allows the pressure-reducing layer to conform to curved body surfaces. The occlusive portion of the dressing therefore provides a moist environment and a barrier against infection while the pressure-reducing portion or component minimizes interaction between the wound and any supporing surface in contact therewith.
摘要:
A method of increasing retention, survival and proliferation of transplanted cells in diseased or damaged tissue types or organ by providing transplanted cells with autologously-derived platelet cells and forming a autologously-derived platelet gel prior or during administration to the tissue type or organ through a delivery device and immobilizing the transplanted cells in the tissue type or organ system.

An implantable system is provided that includes: a cell repopulation source comprising genetic material, undifferentiated contractile cells, or a combination thereof capable of forming new contractile tissue in and/or near an infarct zone of a patient's myocardium; and an electrical stimulation device for electrically stimulating the new contractile tissue in and/or near the infarct zone of the patient's myocardium.
摘要:
This invention relates to an intraluminal stent having a lumen-wall contacting surface and a lumen-exposed surface wherein the stent comprises a first polymer composition comprising fibrin and wherein the stent is suitable to deliver virus to the wall of a lumen of the body. The invention also relates to methods for making the stent and to methods for delivering nucleic acid to cells accessible from a wall of a body lumen.
摘要:
Activation of an enzyme in a bodily fluid is detected based on the amount of cleavage of a substrate for the enzyme. The substrate is tagged with two fluorescent dyes—a donor and an acceptor. The tagged substrate is presented to the bodily fluid. A device emits energy at a first wavelength into the bodily fluid, and detects energy at second and third wavelengths emitted by the dyes in response to the energy at the first wavelength. Prior to enzymatic cleavage of the substrate, the acceptor emits energy at the third wavelength in response to energy at the second wavelength received through fluorescent resonant energy transfer (FRET) from the donor. After enzymatic cleavage of the substrate, the donor emits energy at the second wavelength. The device can determine the concentration of activated enzyme within the bodily fluid based on the relative intensities of energy, at the second and third wavelengths.
