Method of Manufacturing Microstructures
The present invention provides a novel method for manufacturing a microstructure via the use of a deep template, particularly microstructures that may be found on medical devices, such as transdermal patches, for either cosmetic or medicinal purposes.
Method for manufacturing an injection device with a bypass channel and tool for this purpose
A tool and a method for manufacturing a bypass in an injection device are disclosed. The preforms of the injection device are inserted into a tool. A partial region of the cylindrical portion is heated by a heat source. The heated partial region of the cylindrical portion is plastically deformed with a male die part of the tool, so that the bypass channel is formed.
Heat-curling polymeric needle for safe disposal
A needle having shaft that forms a tip and a portion proximate to the tip that is formed from a shape memory polymer. The shaft of the needle may be programmed to curl from a straight configuration to a curved configuration upon triggering by heat, thereby moving the sharp tip and providing a non-stick needle for safe and easy disposal.
SMOOTH FILM LAMINATED ELASTOMER ARTICLES
An elastomeric article for sealing a container includes an elastomeric body having an external sidewall surface and an external crown surface and a first fluoropolymer film layer having an internal surface and an external surface. The internal surface of the first fluoropolymer film layer is laminated to an entirety of the external sidewall and crown surfaces of the elastomeric body. The external crown surface of the first fluoropolymer film layer includes a drug contact surface configured to contact a drug contained in the container and the external sidewall surface including a sealing surface for contacting an interior surface of the container. The external surface of the first fluoropolymer film layer is substantially free of striations.
MICRONEEDLE ARRAYS WITH UNDERCUT FEATURES FOR CUTANEOUS AND NON-CUTANEOUS DRUG DELIVERY
The disclosed methods relate to forming microneedle arrays from a production mold that comprises a flexible mold material. The disclosed methods can be used to reproducibly manufacture undercut dissolvable and coated microneedle arrays with various shapes and structures.
Testing assemblies and testing methods for drug delivery devices
A testing assembly for a drug delivery device is disclosed. The testing assembly can include a pressure vessel having a sealed pressure chamber that is configured to be pressurized to a predetermined pressure. The pressure vessel further defines an injection opening extending from an exterior thereof to the pressure chamber. A pierceable barrier extends over and seals the injection opening. The testing assembly further includes a measurement device disposed within the pressure chamber and a container aligned with the injection opening, such that the container is configured to collect a dose of a drug delivered via a drug delivery device through the pierceable barrier and the measurement device is configured to measure the dose of the drug.
MANUFACTURING PROCESS FOR HOLLOW PLUNGER ROD
A method of manufacturing a plunger of a drug delivery device includes forming a plunger body. The method includes loading the plunger body into a cavity of a first molding tool of a molding system. The cavity is at least partially defined by a first molding portion and a second molding portion. The method includes coupling a second molding tool to the first molding tool to form a plurality of channels defined by grooves in the first and second molding tools, and injecting molten plastic into the plurality of channels to form an overmolded plunger body. The overmolded plunger body includes a head coupled to the first end of the plunger body and a foot coupled to the second end of the plunger body. The foot is at least partially coupled to the inner wall and the head is coupled to the outer wall of the plunger body.
DEVICE AND METHOD FOR LOADING PREFABRICATED PARTS INTO A MOLDING TOOL OF A PRESS, AS WELL AS A PRESS COMPRISING SUCH A DEVICE
A device and a method for loading prefabricated parts into a molding tool of a press for the production of molded parts, in particular for the production of elastomer molded parts. For this purpose, the device comprises a plate-like carrier element with a top and a bottom intended for attachment on or to the press and a holding device for accommodating at least one interchangeable platen equipped with the parts. The holding unit is arranged on the supporting element at a clear distance from its bottom and the interchangeable platen comprises a plurality of passage openings to accommodate the parts. Furthermore, the device comprises a platen with pins which are arranged between the bottom of the supporting element and the holding unit, wherein the pins align with the passage openings.
Microstructure for transdermal absorption and method for manufacturing same
The present invention relates to a microstructure including a biocompatible polymer or an adhesive and to a method for manufacturing the same. The present inventors optimized the aspect ratio according to the type of each microstructure, thereby ensuring the optimal tip angle and the diameter range for skin penetration. Especially, the B-type to D-type microstructures of the present invention minimize the penetration resistance due to skin elasticity at the time of skin attachment, thereby increasing the penetration rate of the structures (60% or higher) and the absorption rate of useful ingredients into the skin. In addition, the D-type microstructure of the present invention maximizes the mechanical strength of the structure by applying a triple structure, and thus can easily penetrate the skin. When the plurality of microstructures are arranged in a hexagonal arrangement type, a uniform pressure can be transmitted to the whole microstructures on the skin.
SYSTEMS, DEVICES AND METHODS OF MAKING SURGICAL SUTURES HAVING REFORMED, REDUCED DIAMETER, OFFSET TIPS
A system for making a surgical suture having a reformed tip includes a receiver die having a top surface, a bottom surface, and an elongated channel formed in the top surface that extends between first and second ends of said receiver die. The elongated channel includes a suture channel having a first end and a second end, a first sloping surface that extends downwardly between the first end of the suture channel and the first end of the receiver die, and a second sloping surface that extends downwardly between the second end of the suture channel and the second end of the receiver die. The system includes an upper die having a top surface and a bottom surface that opposes the top surface of the receiver die. The system has an open die position in which the bottom surface of the upper die is spaced away from the top surface of the receiver die and a closed die position in which the bottom surface of the upper die is in contact with the top surface of the receiver die. A cutting element is coupled with the receiver die and the upper die.
