  • Patent number: 8375688
    Abstract: A package for a cryopreservation container including at least an adhesive fluoropolymer film. The package for a cryopreservation container makes it possible to store blood, rare cells and vital tissues in a very low temperature environment without any damage to the container. Further, the sealing strength resulting from heat sealing after placing a cryopreservation container in the packages is very good. Therefore, liquid nitrogen can be inhibited from entering the inside and thus contamination with bacteria, viruses or the like contained in liquid nitrogen can be avoided and the package can be prevented from being broken by expansion of intruder liquid nitrogen on the occasion of thawing. Also disclosed is a method for packaging a cryopreservation container and a method of producing a package for a cryopreservation container.

  • Patent number: 7615063
    Abstract: The present invention provides a nerve regeneration-inducing tube in which nerve is inserted into a tubular structure and can be easily sutured and fixed without resort to any special instruments or operations, thereby allowing nerve cells to efficiently proliferate and grow in the correct direction. The nerve regeneration-inducing tube of the present invention includes: a tubular structure (A) made of a biodegradable material or a bioabsorbable material and provided inside with a matrix (B) having linear nerve-inducing channels and being made of a biodegradable material or a bioabsorbable material; and a definite space part provided at one end of the tubular structure (A).

  • Publication number: 20090065507
    Abstract: It is demanded that packages for cryopreservation containers which can prevent the conventional cryopreservation containers stored at very low temperatures, namely ?80 to ?196° C., from being damaged and are excellent in heat sealability be developed. The present invention provides a package for a cryopreservation container comprising at least an adhesive fluoropolymer film. The package for a cryopreservation container according to the invention makes it possible to store blood, rare cells and vital tissues in a very low temperature environment without any damage to the container. Further, the sealing strength resulting from heat sealing after placing a cryopreservation container in the packages is very good and, therefore, liquid nitrogen can be inhibited from entering the inside and thus contamination with bacteria, viruses or the like contained in liquid nitrogen can be avoided and the package can be prevented from being broken by expansion of intruder liquid nitrogen on the occasion of thawing.

  • Publication number: 20080082060
    Abstract: The present invention relates to a cord blood correcting device characterized by including: a branch indwelling needle having an outer cylinder needle provided on a distal end side, an inner needle drawing tube portion provided on a proximal end side, an inner needle provided inside the inner needle drawing tube portion, and a liquid outflow tube portion which branches off from the inner needle drawing tube portion; a cord tissue holder having a base portion and a holding portion for holding the cord tissue; and connecting means for interconnecting the branch indwelling needle and the cord tissue holder, and in that the connecting means has a structure for changing an angle between a puncture direction from the proximal end side to the distal end side of the branch indwelling needle and a holding direction from the base portion to the holding portion of the cord tissue holder.
