Systems and methods are provided that reduce the likelihood of infection caused by microorganisms. In general, microorganism population control can be achieved by exposing the population to an effective dose of electromagnetic radiation sufficient to cause a reduction in proliferation of the microorganism, wherein the electromagnetic radiation has a center wavelength between about 385 nm and about 425 nm. In preferred embodiments, the systems and methods described herein can be embodied in catheterization systems.

Systems and methods for reducing the proliferation of microorganisms

Compositions of cross-linked polyvinylpyrrolidone (PVP) are disclosed that are generally in the form of an elastic, hydrophilic, water-insoluble viscous cohesive mass of material that has many important medical uses including uses as a filler for implants. The present invention also involves a process for producing such compositions.

Implant filling material and method

An improved micro-implantation method and composition for filling depressed scars, unsymmetrical orbital floors, muscle, lip, and other soft tissue defects is provided for use in reconstructive surgery procedures. Textured micro particles having an outside diameter between about 30 microns and 3000 microns are used with an appropriate physiologic vehicle cannula and syringe and/or pressure delivery system into a predetermined locus. The particles provide long-term filling of defects without migration loss.

Textured micro implants

A one or two-piece, one-time or reusable catheter anchoring system is disclosed which may be utilized to facilitate the anchoring of a urinary catheter, an umbilical catheter or other draining device to the thigh or abdomen of the patient in a manner which prevents irritation and accidental dislodgement.

Catheter anchoring device

Novel principles for treating urological and gastric fluid reflux disorders are disclosed wherein textured micro particles having a combination of average unidimensional particle size range and average particle texture which cooperate substantially to prevent loss of the micro particles from any injection site.

Treatment of urological and gastric fluid reflux disorders by injection

An adhesive patch for anchoring an intravenous needle to the skin of a patient at the transcutaneous insertion site is disclosed in which a patch of continuous flexible asymmetrically elastic sheet material having one side covered with a layer of biocompatible adhesive is provided substantially shaped as large and small abutting parallel rectangles integrally joined parallel to the easy axis of elasticity and adapted to engage an intravenous needle. The small rectangle is configured such that a portion can disengage from the larger rectangle and fold on itself as a tab and adhesively engage the periphery of the hub of the needle and wherein the larger rectangle has a central shaped cut out facing the small rectangle and is adapted to fold over the tab and adhesively attach to the skin thereby attaching the entire assembly to the skin. A layer of peelable release paper adhering to said adhesive is provided for packaging.

Device for anchoring an intravenous needle

An improved bio-osmotic gel for filling implant lumens consisting substantially of an amount of a bio-compatible organic polymer and a solution of bio-compatible salt is disclosed which exhibits osmotic qualitites closely paralleling that of human body serum and improved radiolucency with respect to silicone oil and saline. The bio-osmotic gel can contain a polymer having the empirical formula [(CHCH.sub.2).sub.2 N(CH.sub.2).sub.3 CO].sub.n i.e. polyvinylpyrrollidone. The bio-compatible salt can be made of a low Z value salt such as sodium bicarbonate, sodium acetate, or sodium lactate. The gel material should have an osmolarity between 250 and 350 milliosmoles and have an X-ray absorption under standard exposure approximately equal to that of breast tissue such that processed mammographic X-ray film will have an optical density of 1.2 to 1.3 and an average penetrance of between 9.2 and 30.0 milliroentgens.

Nose tube anchoring strip

Capsular contracture causing firmness of soft silicone implants is a serious problem that may result from several causative factors that have as their final pathway, the development of increased scar tissue. The present invention has altered the formation of this scar encapsulation of silicone implants by texturing the silicone surface in order to gain fibroblast ingrowth into the interstices and thus prevent micromotion at the host prosthesis interface. It has been found that this produces a thinner fibrous capsule. Previously published work pertaining to animals and man has shown that similar texturing of tetrafluoroethylene (Teflon) and other substances achieves these goals. In accordance with work leading up to the present invention, textured silicone samples have been implanted in the subcutaneous layer of rabbits, the capsule formation and the host-prosthesis interface studied histologically. A difference between the smooth surface and the textured surface could be measured wherein the textured surface had a thinner capsule without contracture and the smooth surface had a thicker capsule with contraction.

Textured silicone implant prosthesis

An adhesive coated sheet particularly shaped to facilitate the anchoring of a nasal-gastric tube to the nose of a patient to prevent accidental dislodgment thereof.

A temperature control device containing a mixture of de-ionized water, propylene glycol, polysaccharides and plant gum for providing a moldable pillow-like surface for cooling/heating and positioning body organs or parts. A multi-layered container including an insulator, a radiant heat reflecting layer and a liquid impermeable outer layer permit autoclaving and provide directional cooling/heating. The inclusion of appropriate phase change chemicals or reciprocal ion-type chemicals or metal particles facilitate the stabilization of temperature over a predetermined temperature range.
