| 20090007937 | APPARATUS AND METHOD FOR WASHING BIOLOGICAL MATERIAL - In a general aspect, an apparatus for washing biological material is provided which includes an outer sleeve, and an inner sleeve disposed within the outer sleeve. The outer sleeve has an open end for receiving the biological material, and an opposed closed end. The inner sleeve is detachably and slidably positioned within the outer sleeve, and includes a first port for receiving and dispensing washing liquid, a second port defining a liquid flow path between an interior of the inner sleeve and an interior of the outer sleeve, and a filter disposed in the second port. The filter allows passage of washing liquid but not passage of the biological material therethrough. A chamber, formed between the filter and the closed end of the outer sleeve, is configured to permit flow of washing liquid via the filter while retaining the biological material therein. | 01-08-2009 |
| 20090011506 | APPARATUS AND PROCESS FOR WASHING TISSUE AND/OR CELL - An apparatus for washing cells and/or tissue includes an outer sleeve, an inner assembly, and a filter. The outer sleeve includes a closed end and an open end. The inner assembly is axially movable in the outer sleeve. The filter is affixed to the inner assembly, wherein a chamber is formed by the filter, the outer sleeve, and the inner assembly. Furthermore, a process for washing cells and/or tissue comprising: (a) providing an apparatus as described above, wherein the cells and/or tissue and washing liquid are disposed in the chamber, and (b) axially moving the inner assembly to wash the cells and/or tissue. | 01-08-2009 |
| 20100168871 | ARTIFICIAL DURA BIOMEDICAL DEVICE AND BRAIN SURGERY METHOD UTILIZING THE SAME - An artificial dura biomedical device and a brain surgery method utilizing the same are disclosed. The steps includes: fixing an artificial dura to a partial skull; and fixing the partial skull with the artificial dura to a cut hole of a whole skull. The artificial dura biomedical device includes an artificial dura and a connecting element. The connecting element fixes the partial skull with the artificial dura. | 07-01-2010 |
| 20110015654 | SPINAL DISC ANULUS REPAIR METHOD AND APPARATUS - An apparatus for anulus fibrosus repair includes a shaft, a pair of curved suturing needles mounted in parallel on the shaft, and a rotational driving mechanism connected to the shaft, which is configured to rotate the shaft and the pair of needles about a rotation axis of the shaft. Each needle includes a substantially semi-annular body having a proximal end, a distal end, an inner periphery, and an outer periphery, and an arm extending radially inward from the proximal end, in which a concavity is formed in the body proximate to the distal end extending in a direction away from it. Also disclosed is a suturing technique associated with use of the repair apparatus. | 01-20-2011 |
| 20110117199 | FOAMY BIOMATERIAL FOR BIOLOGICAL TISSUE REPAIR - A kit for producing a foamed biocompatible material includes a container configured to sustain a high pressure, and a tissue-repair composition placed in the container. The composition contains a biocompatible material, a liquid carrier, and a gas. The container has an internal pressure of greater than 1 atm and less than 250 atm, and includes a valve and a nuzzle for releasing from the nuzzle a foam formed of the composition upon opening the valve. Methods of producing and applying the biocompatible material are also disclosed. | 05-19-2011 |
| 20110137318 | INJECTABLE THERMOPLASTIC POLYMERS FOR BIOLOGICAL TISSUE REPAIR - A method for filling a bone defect in a subject in need thereof is disclosed. The method includes heating a bone cement composition at a first temperature where the bone cement composition is fluidic, and delivering an effective amount of the fluidic bone cement composition at a second temperature to the bone defect thereby filling the bone defect and allowing the fluidic bone cement composition to solidify, the second temperature being sufficiently high for maintaining the bone cement composition fluidic without causing thermal necrosis. Also disclosed are systems for carrying out the method. | 06-09-2011 |
| 20110160732 | Bone Repairing Kit and Method for Bone Repair - A bone repairing kit including a drilling device, a pushing device, a clamping member and a hole saw is provided. An end of a tube body of the drilling device is a knife portion. When the tube body rotates with respect to a femur, a bone column is cut by the knife portion and located in the tube body. The pushing device includes a hollow tube and a push bar. The hollow tube is for receiving the tube body. The push bar is for touching and pushing the bone column in the tube body. The clamping member is for clamping the bone column. The hole saw includes a receiving body and cutting knives. The receiving body has a recess for receiving an end of the bone column. The cutting knives surrounding on an inner wall of the recess are for cutting an edge of the end of the bone column. | 06-30-2011 |
| 20120004675 | DEVICE FOR FIXING SOFT TISSUE - A device for fixing soft tissue. A sleeve is detachably connected to a self-drilling tapping screw, moving and rotating the self-drilling tapping screw. A guide bar is detachably connected to the self-drilling tapping screw and fit in the sleeve. A fixing pin is fit in a washer and connected to the self-drilling tapping screw. The guide bar is detachably fit in the fixing pin. The fixing pin abuts the washer and the self-drilling tapping screw. | 01-05-2012 |
