A cavity illumination system according to the present disclosure may include one or more illumination elements composed of a transparent or semi-transparent, biocompatible sterilizable polymer and one or more illumination sources. The sterilizable polymer operates as a waveguide. An illumination element may incorporate micro structured optical components such as for example gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The micro structured optical components may also be used to polarize and/or filter the light energy entering or exiting the illumination element.

A medical device for use during a gynecological procedure includes a main body, an attachment rim disposed at a first end of the main body, and a valve securing element disposed at a second end of the main body. A valve is disposed between the main body and the valve securing element.

A medical device and a method for preparing a patient's body to receive a bodily implant are provided. The medical device includes a needle member configured to be inserted into a tissue layer. The needle member has a proximal end portion and a distal end portion. An adjustment member is coupled to the proximal end portion of the needle member. The adjustment member includes an adjustment screw and a nut for setting a predetermined depth of insertion of the needle member within the tissue layer. The adjustment member further includes an adjustment member support configured to provide a support to the adjustment screw and the nut. The adjustment member is configured to move between a first position and a second position with respect to the adjustment member support to limit insertion of the needle member within the tissue layer to the predetermined depth.
