Abstract: An implantable electric lead arrangement for a medical implant system includes an implantable electric lead with parallel lead wires wound in an elongated helix about a central longitudinal axis. At least one support wire is parallel to the lead wires and has a higher strain energy absorption capacity than the lead wires to mechanically strengthen the lead wires against external impact force.

Abstract: An implantable electric lead arrangement for a medical implant system includes an implantable electric lead with parallel lead wires wound in an elongated helix about a central longitudinal axis. A conical shape lead core is fixed and enclosed within the wire helix for providing impact strain relief to the electric lead by resisting radial and/or axial deformation from external impact force. The conical shape of the lead core is configured for a smooth transition between a lead core portion of the electric lead that is protected against external impact force and a non-lead core portion of the electric lead that is unprotected from external impact force.

Abstract: A novel implantable electric lead arrangement is described for medical implant systems such as middle ear implants (MEI), cochlear implants (CI) and vestibular implants (VI). An electric lead contains parallel lead wires wound in an elongated helix about a central longitudinal axis. A lead core is fixed and enclosed within the wire helix for providing impact strain relief to the lead wires by resisting radial and/or axial deformation from external impact force.

Abstract: It is described a portable equipment for providing a user with air purified from solid and/or gaseous polluting substances, comprising at least: —a housing (1) to be worn by the user (for example hanging from his/her belt), containing at least filtering means (2) for detaining the polluting substances which are present in the air and means (3) for sending to delivery means (5) the air coming out from the filtering means (2); —means (6) connecting the housing (1) to the delivery means (5), and —the delivery means (5) to be applied on the head of the user and comprising at least a diffuser (7) for conveying the filtered air to the nose and mouth of the user (thus creating an area filled with clean air) and supporting means (8) for the diffuser (7). The equipment has limited size and weight and can be easily carried by the user without limiting his/her free movements.
