摘要:
A brush assembly includes a handle and a brush head attached to the handle. The brush head includes a base with a plurality of integral bristles and a matrix. The matrix is made of sponge, foam or other compressible material. As the brush is used on a person or an animal skin or scalp, the hair or fur causes the matrix to compress and expose the bristles. When the brush is removed, the matrix springs back and removes any hair, fur, or other material entangled in the hair. Optionally a vibrating device is incorporated into the brush to provide massaging of the skin and/or scalp.

A method and apparatus for detecting stains, urine, odor and feces, and more particularly, the combination of a black light detector and a liquid reservoir and/or trigger pump dispensing vehicle for containing stain removing chemicals is provided. The black light is selectively and removably mounted or positioned in the body of the dispensing vehicle.

摘要:
Methods of inducing the expression of a proteoglycan such as aggrecan in a cell are described. A method is described which includes transfecting a cell with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein operably linked to a promoter. The LIM mineralization protein can be rLMP, hLMP-1, hLMP-1s, or hLMP-3. Transfection maybe accomplished ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid. The method can be used to induce proteoglycan synthesis in osseous cells or to stimulate proteoglycan and/or collagen production in cells capable of producing proteoglycan and/or collagen (e.g., intervertebral disc cells including cells of the nucleus pulposus and annulus fibrosus).
摘要:
The invention provides a bone implant, or osteograft, with improved retention of bioactive agents within the surface of the osteograft. Pits or pits formed within the surface of the osteograft have porous plugs placed within them to retain fluid comprising bioactive agents. Pits can also be formed so that the dimensions of the pits facilitate retention of fluid within a pit by hydrostatic attraction of fluid molecules within the pit.

Described are medical devices for supporting or inducing bone growth including an implant body defining one or more separation-assist lines that facilitate separation of the body into two or more substantially pre-defined pieces. The implant body can be used and implanted as a whole or may be separated into multiple pieces, some or all of which can be used at one or multiple implant sites in a patient. Separation-assist lines in implant bodies can serve a dual role in imparting increased and controlled flexibility to the overall body when used as a whole at an implant site. Also described are methods of making and using, and kits including, such medical devices.
摘要:
A pull tab is formed at a separable edge of each of a plurality of individually separable sheets of outwardly faced adhesive tape wound into a roll by a non-adhesive portion carried on the adhesive layer of the tape to facilitate gripping and removal of an outermost sheet from the tape roll to expose an underlying sheet. The separable edges extend at least partially through the tape roll dividing the tape into a plurality of separable sheets and across substantially all of the lateral extent of the roll. The separable edge can be two spaced separable edges disposed in registry with each non-adhesive portion to define opposite leading edges.
摘要:
A method of treating avascular necrosis (“AVN”) comprising administering one or more osteoinductive formulations to the site of AVN disease progression. The method involves the combination of a core decompression technique, followed by the introduction of one or more osteoinductive formulations into the decompression core, and concluding with capping of the lateral aspect of the decompression core with a femoral core cap. The osteoinductive formulations of the invention comprise one or more osteoinductive agents and suitable carrier molecules. The femoral core cap retains the osteoinductive formulation within the decompression core, thereby preventing leakage of the osteoinductive formulation from the decompression core. The method of the invention optionally comprises introduction of autograft or allograft with the osteoinductive formulations of the invention. The method of the invention further optionally comprises incorporation of sustained release compositions to provide extended periods of osteogenesis.
摘要:
An interbody osteogenic fusion device is provided that includes opposite end pieces with an integral central element. The end pieces are sized to maintain the height of an intervertebral disc space. The central element has a much smaller diameter so that the osteogenic fusion device forms an annular pocke around the central element. An osteogenic material is disposed within the annular pocket between the opposite end pieces. In one embodiment, the osteogenic material constitutes a collagen sheet soaked in a solution containing a bone morphogenetic protein. The osteogenic fusion device is configured so that the osteogenic material is in direct contact with the adjacent vertebral bone. In addition to the enhanced area of contact between the vertebral bone and the fusion material, the inventive osteogenic fusion device reduces stress-shielding and minimizes the radiopacity of the implant so that growth of the fusion mass can be continuously assessed. In yet another embodiment, the osteogenic fusion device includes at least one end piece with a truncated surface. The osteogenic fusion devices of the present invention may be combined with other fusion devices to form an implant system. The implant system includes at least one load bearing member having a truncated surface configured to nest within another load bearing member, preferably the load bearing, osteogenic fusion device of the present invention. The invention also provides implant systems comprising adjacent load bearing members connected to one another to resist lateral separation. Methods of promoting fusion bone growth in the space between adjacent vertebrae utilizing devices and systems of the invention are also described.
摘要:
A small dental syringe has a spring biased plunger and a split, adjustable thumb receiving member. The dimensions of the syringe result in a shorter, over-all, distance a user must spread his/her thumb from the fingers gripping the syringe for aspirating.
