摘要:
Pork and other meat products are cured with pickling solutions from which nitrite is effectively exhausted during curing, thereby avoiding nitrosoamine formation, by buffering the solutions at the requisite acid pH with an alkali metal (M) glassy phosphate of the formula M(PO.sub.2 OM).sub.n OM having an M/P mole ratio of 1.188/1 to 1.250/1 and an average chain length (n) of about 8-11.

摘要:
A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust, the release of the substance.

Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. In some embodiments, the covering may be configured and sized for receipt by an implant device. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust the release of the substance.

There is provided an implant retaining device, which has the effect of preventing an intervertebral implant from jutting out of the receiving bed. The implant retaining device generally includes a plate having at least one throughbore to receive a screw, and a screw for securing the plate to the vertebrae. The plate may be dimensioned to cover a portion of the opening of a receiving bed, and thus, need only be secured to a single vertebral body. In an alternate embodiment, the plate may be used during bone fracture correction procedures to prevent a bone screw from backing out of engagement with adjacent bone sections. A method of retaining an intervertebral implant using the device is also provided.
摘要:
Fenestrated wound repair scaffolds and methods for forming scaffolds involve dispersing human collagen having a preserved amount of native constituents in solution, depositing the human collagen dispersion in a tray, forming openings in the collagen dispersion and removing the liquid component to form a fenestrated wound repair scaffold. Fenestrated wound repair scaffolds include a network of openings passing linearly through the wound repair scaffold to form channels for cells to pass into so as to form a series of cell formations therein.

摘要:
A method of manufacturing an osteoinductive osteoimplant is provided which comprises the steps of: demineralizing part or all of at least one surface of a monolithic section of cortical bone to a depth of at least about 100 microns; and, configuring the monolithic section of cortical bone to provide an osteoimplant possessing an outer surface possessing at least one demineralized zone and a non-demineralized zone. An implant produced according to the above method demonstrates improved osteoinduction without producing any clinically significant reduction of strength in critical regions of the osteoimplant.
摘要:
A method is provided for sterilizing and/or deactivating adventitious agent(s) on and/or within a biological material which comprises packaging the biological material, altering the original atmosphere associated with the biological material in order to reduce the level of oxygen to which the biological material is exposed and subjecting the packaged biological material with its altered atmosphere to irradiation.
