A stent comprising an essentially tubular open supporting structure () of interconnected trusses (), whereby the supporting structure () can be widened radially with deformation of the trusses () for application of the stent, and predetermined breaking points () in the supporting structure () for fragmentation of the stent after application, and the ends () of the trusses () that are adjacent to the respective predetermined breaking point () having a joint design and which are provided in the area of the predetermined breaking point (), such that the ends () of the trusses () are held together with articulation under an applied pressure with the predetermined breaking point () broken.

Stent

The invention relates to a method for manufacturing a first ear device having () a first retention element () to be worn at least in part in at least one of the outer ear and the ear canal of a user and a second ear device (') having a second retention element (&#x2032;) to be worn at least in part in at least the outer ear and the ear canal of the user, comprising: defining a data format; measuring the inner shape of the user's outer ear and ear canal; manufacturing the first retention element, wherein the outer surface of the first retention element is individually shaped according to the measured inner shape of the user's outer ear and ear canal; obtaining a digital data set according to the data format, which is representative of the measured inner shape of the user's outer ear and ear canal; providing the user with a personal copy of the digital data set for personal use by the user; and using the personal copy of the digital data set for manufacturing the second retention element, wherein the outer surface of the second retention element is individually shaped according to the measured inner shape of the user's outer ear and ear canal.

Method for manufacturing an ear device having a retention element

The invention relates to a hearing protection earplug comprising a shell () for being worn at least in part in the ear canal of a user, the shell having a sound passage () extending from an outer sound inlet opening () of the shell to an inner sound output opening () adapted to acoustically connect to the user's ear canal, and a noise attenuation button () which is provided at the outer end of the shell, wherein said button is manually movable relative to the shell between a resting position in which the outer sound inlet opening of the shell is closed by the button and at least one communication position in which the outer sound inlet opening of the shell is at least partially opened by the button for enabling sound communication between the environment and the sound passage of the shell, wherein the sound passage () is designed such that it has a sound attenuation of less than 10 dB averaged over the audible frequencies. The invention also relates to a use of such an earplug and a method for manufacturing such an earplug.

The invention relates to a hearing protection earplug () to be worn at least in part in a user's ear canal, comprising a shell () having a outer surface individually shaped according to the measured inner shape of the user's outer ear and ear canal, and a functional member () engaging said shell in a manner so as to be movable relative to said shell between a first functional position and a second functional position, said shell and said functional member having been produced by an additive layer-by-layer build-up process and having an elasticity of between shore D85 and D65.

Customized hearing protection earplug and method for manufacturing the same

The invention relates to an active hearing protection earplug comprising a shell () to be worn at least in part in a user's ear canal and being adapted to attenuate sound waves arriving at the outer end () of the shell, and an active system () comprising an input transducer () for converting ambient sound into audio signals, an audio signal processing unit () for processing said audio signals, and an output transducer unit () mounted within the shell for converting said processed audio signals into sound output at the inner end of the shell, wherein the amplification of the active system is negative and wherein the output transducer unit comprises at least two separate outputs (). The invention also relates to a method for manufacturing such an earplug.

Earplug and method for manufacturing the same

The invention relates to a passive hearing protection earplug for being worn at least in part in the ear canal () of a user, comprising a hard shell () having an elasticity of from shore D 85 to shore D 65 and pulling means () which are adapted for being manually operated by the user and which are provided at the outer end of said shell, said shell having an outer surface individually shaped according to the measured inner shape of the user's ear canal and outer ear (). The shell has a size and an outer shape which are adapted to enable said shell to be manually moved, by seizing the pulling means, from a sound attenuation position into a communication position from which it is automatically returned into the attenuation position by elastic forces exerted by deformed parts of the user's ear canal and concha upon release of the pulling means. The invention also relates to a use of such an earplug and a method for manufacturing such an earplug.
