System for Converting an Existing Ethylene Oxide Vacuum Sterilizer into a Chlorine Dioxide Vacuum Sterilizer
This invention serves to repurpose existing ethylene oxide sterilization chambers utilizing a novel chemical means of sterilization. Ethylene oxide is a longstanding gaseous sterilant for medical devices but has increasing problems associated with its hazards. Ethylene oxide is a carcinogenic and explosive chemical, and its emissions can be very harmful and cause serious health risks. Due to this, the FDA and many medical device manufacturers are trying to reduce or eliminate the use of the gas. Chlorine dioxide gas is a nearly identical alternative mode of sterilization that is non-carcinogenic and non-explosive. If firms choose to eliminate the use of ethylene oxide but do not want to waste the capital expenditure on existing sterilizers, they can instead utilize the ethylene oxide-to-chlorine dioxide conversion system of the present invention and use an effective and environmentally friendly form of sterilization in a system they already possess.
BARRIER LAYER
A barrier layer and corresponding method of making provide anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a medical device implantable in a patient. The barrier layer can be combined with a medical device structure to provide anti-adhesion characteristics, in addition to improved healing, non-inflammatory, and anti-inflammatory response. The barrier layer is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent.
DEVICE RETENTION MECHANISM AND METHOD
A device retention assembly includes a delivery system and a device retention mechanism retaining the delivery system. The device retention mechanism includes a tray, a base coupled to the tray, and retaining flanges pivotally coupled to the base. The delivery system is enclosed within an opening defined by the base and retaining flanges. A key locks the device retention mechanism in the closed position retaining the delivery system. The key must be removed to unlock the device retention mechanism to release the delivery system.
Stertile packaging container
The present disclosure in one aspect provides a sterile packaging container comprising a container body with a cross-sectional shape that is constant along the majority of the longitudinal axis, a cover and a closure assembly that inhibits the passage of microbial contaminants. The container is configured such that the interior of the container can be sterilized. The sterile packaging container described herein allows one to manufacture a sterile packaging tube exercising the smallest possible volume.
Safe operation of integrated negative pressure wound treatment apparatuses
Disclosed herein are systems and methods for safe operation of a wound treatment apparatus with electronic components integrated on or within a wound dressing. In some embodiments, the electronic components include a power source, an isolation circuit, a controller, a capacitor, and a negative pressure source. The isolation circuit provides multiple activation states with at least one state preventing application of power to the other electronic components capable of storing electrical energy, thereby providing a safe operation of the apparatus. For example, sterilization of the apparatus can be performed safely.
Sterilization test device
A sterilization process test device for verifying the efficacy of a sterilization process includes a tubular body defining a chamber for containing at least one sterilization indicator and a cap to sealingly close the tubular body. The tubular body includes at least one hole, which is covered by a gas and steam permeable cover. The only flow path into the chamber is provided through the steam and gas permeable cover and the at least one hole, which when combined are configured to control and restrict a flow of steam or a gaseous sterilization medium from an external environment.
ASSEMBLIES INCLUDING A PRE-LOADED IMPLANT AND METHODS OF STERILIZING ASSEMBLIES
Aspects of the disclosure relate to storage assemblies including at least part of a delivery device and an implant. The storage assemblies are configured to trap sterilizing ethylene oxide gas using its high water solubility and converting the escaped ethylene oxide to less detrimental ethylene glycol and ethylene chlorohydrin to protect the implant from damage. In one example, the storage assembly includes an inner container housing the implant and sterilizing fluid and an outer container positioned over the inner container, wherein the outer container is at least partially filled with aqueous water. The implant may be a prosthetic heart valve. Aspects of the disclosure also relate to methods of sterilizing the storage assemblies of the disclosure.
Fluid connector
Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.
Ethylene oxide treatment indicator, label and method of use
The present invention provides an indicator useful in confirming successful sterilisation and/or nucleic acid decontamination by ethylene oxide (EtO) treatment. The invention also provides a label comprising said indicator and methods for use of the indicator and label in a method of EtO treatment.
MEDICAL RUBBER COMPOSITION, MEDICAL RUBBER PART, AND PRE-FILLABLE SYRINGE
A medical rubber composition can contain, comprise, consist, or consist essentially of: (a) an isobutylene-isoprene rubber: (b) a diene-based rubber; and a silica having a BET specific surface area not lower than 130 m.sup.2/g. An amount of (a) the isobutylene-isoprene rubber contained in 100 parts by mass of a rubber component composed of (a) the isobutylene-isoprene rubber and (b) the diene-based rubber can be larger than 30 parts by mass and smaller than 55 parts by mass.
