摘要:
A method for directing vessel growth toward a blood-deficient site in a mammal comprising implanting into the mammal an assembly of at glass fibers to form a vascular bridge with a first end of the vascular bridge in contact with the blood-deficient site and a second end of the vascular bridge remote from the blood-deficient site. Over time the bridge biodegrades and promotes vascularity in the direction of the bridge.
摘要:
A method for treating a wound, and a dressing for wound care management comprising a three-dimensional body of glass-based fibers comprising one or more glass-formers selected from the group consisting of P2O5, SiO2, and B2O3; at least about 25 wt % of the fibers have a diameter between about 200 nm and about 4000 nm, and a length:width aspect ratio of at least about 10. In another form, the glasses are in the form of particles in an ointment or cream applied to a wound. In yet other forms the glasses are employed as fibers formed into sutures for closing a wound, or as particles in a surgical glue for closing a wound.

摘要:
A biocompatible composition for tissue repair or regeneration in mammals comprising one or more glass former compounds selected from the group consisting of B2O3, P2O5, and SiO2 and director elements selected from the group consisting of Cu, Sr, Zn, Fe, Mn, Cr, V, Nb, Mo, W, Ba, Co, S, Al, Ti, Y, Mg, Si and/or Ni to promote in vivo calcium compound formation of calcium carbonate or other calcium compounds other than hydroxyapatite. Upon direct application of the biocompatible composition to a mammalian host, calcium carbonate or other calcium compounds other than hydroxyapatite form upon bioreaction of the composition with bodily fluids.

摘要:
A scaffold for implantation into a mammal to facilitate vessel growth in repair, regeneration, and/or proliferation of bodily tissue, where the scaffold is based on a borate, silicate, or phosphate, glass-former and is biodegradable upon implantation in mammals. The scaffold includes one or more trace elements from the group consisting of Cu, F, Fe, Mn, Mo, Ni, Sr, and Zn which are released into the host to support vessel growth. A method involves implantation of such scaffolds.
摘要:
A method and compositions for wound care management comprising a dressing comprising a three-dimensional body of glass-based fibers comprising 40 to 80 weight % B2O3, wherein at least 25 wt. % of the fibers have a diameter between 200 nm and 4000 nm, and a length:width aspect ratio of at least 10. The glasses may also be used for wound care as fibers formed into sutures, as particles in surgical glue to close a wound, or as particles in an ointment or cream to apply to a wound. The compositions may comprise glass formers P2O5 and/or SiO2; alkali oxides selected from Li2O, Na2O, K2O, and Rb2O; and/or alkaline earth oxides selected from MgO, SrO, BaO and CaO. The compositions may further comprise 0.05 to 10 wt. % of one or more trace elements selected from Ag, Cu, F, Fe, Mn, Mo, Ni, Sr, and Zn.
