Lamellar Corneal Autologous Or Homologous Graft In Refractive Surgery
A method of lamellar corneal graft implantation is disclosed herein. In one or more embodiments, the method includes the steps of: (i) modifying a genetic component of a lamellar cornea or other tissue of an animal so that the lamellar cornea or other tissue of the animal can be used for human transplantation; (ii) decellularizing the lamellar cornea or other tissue ex vivo using chemical means; (iii) modifying a shape of the lamellar cornea or other tissue before or after transplantation; and (iv) applying a photosensitizer and ultraviolet radiation to the lamellar cornea or other tissue so as to crosslink collagen and intercellular proteins of the lamellar cornea or other tissue, kill the cells exposed to the photosensitizer, and eliminate an immune response by a host to the implanted lamellar cornea or the tissue.
Flexible active species generator and use thereof
The disclosure relates to a flexible active species generator comprising: a first electrode of a conductive metal thin film; a second electrode of a ground electrode; a flexible dielectric layer of an insulator formed between the first electrode and the second electrode; and a plasma resistant functional layer formed between the dielectric layer and the second electrode, wherein the first electrode and the second electrode are electrically connected to an external power supply to generate an atmospheric pressure plasma to generate active species. The flexible active species generator has a plasma resistant function to prevent deformation and decomposition of an insulator caused by the plasma as well as an active species generating function from atmospheric pressure plasma, and has durability and safety, which is thus applicable to articles, foods, garments and human body in various forms.
METHODS, SYSTEMS, DEVICES, AND FORMULATIONS FOR CRYOGENIC FLUIDS
A cryogenic fluid composition may include water (H20), and at least one salt. The ratio of water to the at least one salt is approximately between 1% and 6% salt with the remainder water. A cryogenic fluid production device may include a cylindrical housing, and a heat exchanger disposed within the cylindrical housing. The heat exchanger may include an inlet, a channel, and an outlet. A coolant may be conveyed through the inlet, the channel, and the outlet of the heat exchanger. The cryogenic fluid production device may further include an interior wall, and an auger disposed within the interior wall of the heat exchanger.
VIRAL INACTIVATION METHOD, METHOD FOR PRODUCING DRIED AMNION, AND DRIED AMNION
An object is to develop technology for viral inactivation. As means for resolution, viruses are inactivated by irradiating various articles with microwaves.
Devices, systems, and methods of packaging for a pre-filled drug delivery device
A system for sterilizing a drug delivery device includes a drug delivery device having a first self-healing seal configured to seal a fluid reservoir disposed within the drug delivery device. A sealable container is configured to receive the drug delivery device therein. The sealable container has a base portion and a cover portion. The cover portion has a second self-healing seal positioned to align with the first self-healing seal when the drug delivery device is disposed within the sealable container. A fill port includes a fill path, the fill path being configured to pass through the first and second self-healing seals to fluidly couple the fill port to the reservoir of the drug delivery device. Other systems, methods, and devices of sterilization are also disclosed.
Methods, apparatuses, and systems for inductive heating of foreign metallic implants
Methods, apparatuses, systems, and implementations for inductive heating of a foreign metallic implant are disclosed. A foreign metallic implant may be heated via AMF pulses to ensure that the surface of the foreign metallic implant heats in a uniform manner. As the surface temperature of the foreign metallic implant rises, acoustic signatures may be detected by acoustic sensors that may indicate that tissue may be heating to an undesirable level approaching a boiling point. Once these acoustic signatures are detected, the AMF pulses may be shut off for a time period to allow the surface temperature of the implant to cool before applying additional AMF pulses. In this manner, the surface temperature of a foreign metallic implant may be uniformly heated to a temperature adequate to treat bacterial biofilm buildup on the surface of the foreign metallic implant without damaging surrounding tissue. The AMF pulse treatment can be combined with an antibacterial/antimicrobial treatment regimen to reduce the time and/or antibacterial dosage amount needed to remove the biofilm from the metallic implant.
Filtered product bag with compact form factor
A product bag includes a bladder and an elongated filtration device. The bladder includes opposing first and second film layers defining a product chamber. The first and second film layers are sealed together along a perimeter seal extending along at least a portion of a perimeter of the bladder. The elongated filtration device includes a housing, a filtration membrane disposed in the housing, an inlet adapted for receiving a fluid to be filtered, and an outlet in fluid communication with the product chamber. A majority of the elongated filtration device is embedded between the first and second film layers of the perimeter seal of the bladder to provide for a compact form factor.
A CONTINUOUS RETORT
An apparatus for heat treatment of a product, in particular food product, and especially food product in a container such as a can, bottle or plastic pouch is disclosed. The apparatus comprises an unloading and loading section, a first treatment section having an inner wall defining a processing volume within which product is heated, a transfer section and a second treatment section having an inner wail defining a processing volume within which product is cooled, multiple carriers for retaining product during treatment designed to provide multi-stage pressure reductions that collectively reduce the maximum over-pressure within the apparatus to ambient pressure and thereby eliminate the need for sealable pressure doors or gate valves. The loading section incorporates means of linear movement of said product carriers in a continuous fashion. The carriers includes elements to create cavities between or within successive carriers and a plurality of throughapertures to force heat treatment fluid into direct contact with product as it flows from over ambient to ambient pressure. A heat exchanger recovers energy from cooling product and continuously re-applies that energy to heat product.
MODULAR ASEPTIC PRODUCTION SYSTEM
A modular production system including a plurality of production modules connected in a linear series to form a production tunnel, and collectively defining a production channel, and wherein at least one fluid inlet port defined along the production tunnel, said inlet port is in fluid communication with a pressurized fluid source, whereby influx of fluid from said fluid source through said fluid inlet port acts to maintain the fluid pressure within the production channel at a higher pressure than the atmospheric pressure outside of the production tunnel; and wherein one of said production modules positioned between said proximal-most and distal-most production modules comprises a depyrogenator and/or sterilization module, comprising a transparent tubular body, and an irradiation source positioned external to said transparent tubular body, said irradiation source capable of heating the internal environment of the depyrogenation and/or sterilization module to a temperature sufficient to depyrogenate or sterilize articles passing therethrough, and associated processes.
IMPLANTABLE PUMP FOR DIRECT SODIUM REMOVAL THERAPY HAVING ON-BOARD ANALYTE SENSOR
Systems and methods for performing Direct Sodium Removal (DSR) therapy are provided in which an implantable device includes a pump coupled to an inlet catheter designed for placement in a patient's peritoneal cavity, an outlet catheter designed to be coupled to the patient's bladder, and is operably coupled to an analyte sensor, the pump programmed to transfer and/or cease transfer of fluid from the patient's peritoneal cavity to the patient's bladder for voiding responsive to a level of analyte detected by the analyte sensor. In addition, the system may include a processor that computes an amount of analyte transferred per pumping session.
