Composition And Method For Radiation Synovectomy Of Arthritic Joints
US Patent:
5039326, Aug 13, 1991
Filed:
Sep 15, 1989
Appl. No.:
7/408087
Inventors:
Delbert E. Day - Rolla MO
Gary J. Ehrhardt - Columbia MO
Gary J. Ehrhardt - Columbia MO
Assignee:
The Curators of the University of Missouri - Columbia MO
International Classification:
C03B 1910, C03C 1500, C03C 1200
US Classification:
65 211
Abstract:
A method for preparing nonradioactive microspheres adapted for radiation synovectomy of arthritic joints in a mammal involves forming the microspheres by doping a biodegradable glass material which may be lithium or potassium silicate, lithium or potassium aluminosilicate, lithium or potassium aluminoborate, lithium or potassium germanate or lithium or potassium aluminogermanate with an isotope which may be samarium, holmium, erbium, dysprosium, rhemium or yttrium so that the isotope is chemcially dissolved in and distributed uniformly throughout the glass material. The doped glass material is then treated with an acid wash to produce a thin layer on the surface thereof and heat treated to improve the chemical durability of the glass material by rendering the solubility of the layer lower than that of the underlying glass material.

International Classification:
A61K 4300, A61N 500, C03C 3095, C03C 3097
US Classification:
424 129
Abstract:
Microspheres for radiation therapy of a mammal which have a non-radioactive isotope which emits beta or gamma radiation of therapeutic intensity upon being irradiated. The microspheres also contain elements which do not become radioactive upon irradiation. The chemical durability of the microspheres is such that they do not release a significant amount of radiation emitting radioisotope into the mammal's system upon administration. Microspheres containing phosphorus or yttrium; and carbon, nitrogen, fluorine, sodium, magnesium, aluminum, silicon, potassium, vanadium, manganese, gallium, niobium, iodine and/or lead.
Controlling Vessel Growth And Directionality In Mammals And Implantable Material
US Patent:
8337875, Dec 25, 2012
Filed:
Jan 6, 2010
Appl. No.:
12/683211
Inventors:
Steven B. Jung - Rolla MO, US
Delbert E. Day - Rolla MO, US
Delbert E. Day - Rolla MO, US
Assignee:
The Curators of the University of Missouri - Columbia MO
International Classification:
A61F 2/00
US Classification:
424423
Abstract:
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.

Sep 16, 2013
Appl. No.:
14/028148
Inventors:
Delbert E. Day - Rolla MO, US
Assignee:
THE CURATORS OF THE UNIVERSITY OF MISSOURI - Columbia MO
International Classification:
A61L 15/18, A61L 17/00
US Classification:
424489, 606228, 514769, 514770
Abstract:
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 PO, SiO, and BO; 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.

5039566, Aug 13, 1991
Filed:
Jun 27, 1988
Appl. No.:
7/211823

Assignee:
McDonnell Douglas Corporation - St. Louis MO
International Classification:
B32B 512
US Classification:
428113
Abstract:
A transparent composite material, which may take the form of a plate, includes a polymeric matrix and glass fibers embedded within the matrix. The polymer of the matrix and the glass of the fibers are transparent and have substantially the same index of refraction. A bond exists between the glass of the fibers and the polymer of the matrix. The composite may be formed by immersing the fibers in a monomer and then curing the monomer to a polymer.

Fiber Filled Dental Porcelain
US Patent:
4793809, Dec 27, 1988
Filed:
May 21, 1987
Appl. No.:

Assignee:
Myron International, Inc. - Kansas City KS
International Classification:
A61C 508
US Classification:
433218
Abstract:
Improved dental porcelain compositions and resultant fused porcelain dental restorations are provided which exhibit enhanced strength properties as compared with conventional porcelains. The fiber-filled porcelain compositions of the invention are supplemented with zirconium oxide ceramic fibers in relatively minor amounts of less than 5% by weight. The reinforcing fibers are advantageously predominantly zirconium oxide, and have a relatively short average length of from about 1/32 to 1/4 of an inch. These fibers are normally randomly oriented and homogeneously dispersed throughout the fiber-filled porcelain composition, in order to give a reinforcing fiber network. A completed restoration in accordance with the invention would typically include a core portion formed of the fiber filled porcelain, with the outer portion of the restoration being fabricated from conventional non-fiber reinforced porcelain.
