The disclosure herein includes uses and systems for cataract removal and lens regeneration using endogenous stem cells that results in improved outcomes.

A polyelectrolyte coating comprises at least one polycationic layer consisting of at least one polyarginine as herein defined and at least one polyanionic layer consisting of hyaluronic acid. The polyelectrolyte coating has a biocidal activity and the invention thus further refers to the use of said polyelectrolyte coating for producing a device, in particular a bacteriostatic medical device, more particularly an implantable device, comprising said polyelectrolyte coating, and a method for preparing said device and a kit. Also disclosed is a method of preventing a bacterial infection in an individual.

Antimicrobial compositions for use in locking catheters and other devices are provided. In some embodiments, the composition includes at least one alcohol, at least one biocidal agent which is not an alcohol, and one or more poloxamers; in other embodiments, the composition comprises at least one poloxamer and at least one alcohol. The composition can provide long-lasting antimicrobial activity. Methods of using the composition are also provided.

In present invention oxidation method of viscon cellulose with NO.sub.2 obtained H.sub.3PO.sub.4/HNO.sub.3 is defined liquid and gas media. Regenerated oxidise cellulose (REOC in shorten term) contain in COOH yields are standardised as 18.6-20.1 for textile, 19.8-21.5% for powder samples. Powder and textile (woven and fabric) products are impregnated 1.8-2.4% Ca.sup.+2 ion, 0-1.1% Na.sup.+1 ion, 0.8-1.5% tranexamic acid and 6-aminocaproic acid as antifibrinolytic. Obtained powder and gel products are impregnated Bi.sup.+3, Zn.sup.+2 and Ag.sup.+1 ions for antiseptic purposes. Only Bismuth of them is shown antibacterial effects. Also the aim of present invention is haemostat antimicrobial properties during impregnation of Rifampicin, Gatifloxacin, Doxycycline, Levofloxacin, Lincomycin, Clindamycin, Ciprofloxacin. Haemostatic properties are indicated for all products and antimicrobial properties are shown for some samples. Cytotoxicity, sensitivity and irritation properties are determined in compliance of Pharmacopeias.

A wound packing material, particularly suitable for use in negative pressure wound therapy, comprising a porous material admixed with a chemoattractant. This disclosure further provides methods of manufacturing the wound packing material, and therapeutic methods of using the wound packing material.

A method for preparing a pre-loadable biological heart valve capable of rapid rehydration includes performing a cross-linking treatment, wherein a biological valve is cross-linked by soaking in an aqueous glutaraldehyde solution; performing a hydrophilic treatment, wherein the biological valve is soaked in a solution containing a hydrophilic molecule and a condensing agent, to allow the hydrophilic molecule to be immobilized on the biological valve by chemical grafting; and performing a drying treatment, wherein the biological valve after the hydrophilic treatment and the cross-linking treatment is dried to obtain the pre-loadable biological heart valve capable of rapid rehydration.

A flexible anchor for coupling a suture to a bone is provided. The anchor is composed of non-woven electrospun fibers and has an elongate tubular body that extends from a first end to a second end. The anchor is configured to receive a suture that enters the anchor through a first aperture and exits the anchor through a second aperture. When free ends of the suture are pulled, the anchor transitions from a first configuration to a second anchoring configuration.

Provided are a pharmaceutical composition for wound healing including a surfactant, an antioxidant, a thickener, and SP, a method of treating a wound including administering the pharmaceutical composition to a subject, and a quasi-drug composition for wound healing including a surfactant, an antioxidant, a thickener, and substance.

The pharmaceutical composition of the present invention reduces a wound size, generates new blood vessels, shows dermal and epidermal regeneration effects, matures granulation tissues, and synthesizes collagen, and thus may be used for wound healing.

Disclosed are compositions of matter, protocols, and treatment means for generation of tissues capable of administration in a flowable manner through contain with one or more antibiotics, or derivatives of said antibiotics. In one embodiment the invention provides the treatment of morselized amniotic membranes with antibiotics in a manner as to increase buoyancy of morselized components of said amniotic membranes in order to prevent gravity based accumulation of said morselized tissue. In another embodiment buoyancy of morselized tissue is modulated by contacting said tissue with an antibiotic or derivative thereof in a manner to allow for increased uniformity of said morselized tissue components throughout a vessel. In another embodiment, pancreatic islets are isolated and stored in a manner to prevent gravity based aggregation. The invention pertains to all tissues, with emphasize in a preferred embodiment to tissues which are useful when administered in a flowable manner.
