Abstract: Disclosed is an optical waveguide, for transmitting a guided optical light beam having a wavelength >180 nm, including a core for guiding light made of a first material having a first index of refraction, and a cladding including a thermoplastic elastomer, the innermost layer of the cladding having a refractive index smaller than the refractive index of the outermost layer of the core. Also disclosed is a medical device and waveguide sensors including the optical waveguide, as well as a method of fabrication of the optical waveguide. The method is based on the realisation of a full thermoplastic elastomer preform or a preform having a central aperture. Before or after elongating the preform to a predetermined length and a predetermined lateral dimension, the core of the preform is filled and hardened so as to provide such optical waveguide. Also described is a 3D printing method to realize the preform.

Abstract: Disclosed is an optical waveguide, for transmitting a guided optical light beam having a wavelength greater than 180 nm. The waveguide includes a core layer for guiding light made of a first material having a first index of refraction, and a cladding layer made of a thermoplastic elastomer. Also disclosed are: a medical device and also to a waveguide sensor including the optical waveguide of the invention; a method of fabrication of the optical waveguide. The method includes a step of providing a thermoplastic elastomer preform having a central longitudinal aperture for introducing a liquid polymer, before or after reducing and elongating the preform to a predetermined length and lateral dimension. The method includes a polymerizing step of the core of the formed optical waveguide; and use of the optical waveguide in association with a surgical instrument.

Abstract: The present invention relates to a gynecological device (1) comprising a body part (2) having a vacuum chamber (3), a rod unit (4) with a distal end, a proximal end, and a channel (41) extending between the distal end and the proximal end, a cervix head (5) arranged at the distal end of the rod unit (4), and a sealing mechanism (6) configured to switch between an ambient state and a vacuum state. The rod unit (4) extends to the vacuum chamber (3) of the body part (2) such that the proximal end of the rod unit (4) is located in the vacuum chamber (3) of the body part (2). The cervix head (5) is configured to engage a section of a cervix from a vaginal side. When in the ambient state of the sealing mechanism (6), the vacuum chamber (3) of the body part (2) is sealed and the channel (41) of the rod unit (4) is open to an exterior (7) of the gynecological device (1).
