Ophthalmically compatible contact lenses include lens bodies configured for placement on a cornea of an animal or human eye. The lens bodies are made of a hydrophilic silicon-containing polymeric material. The lens bodies have oxygen permeabilities, water content, surface wettabilities, flexibilities, and / or designs to be worn by a lens wearer even during sleep. The present lenses can be worn on a daily basis, including overnight, or can be worn for several days, such as about thirty days, without requiring removal or cleaning.

Silicone hydrogel contact lenses are provided which have reduced modulus and contact angle properties, and which have acceptable wettabilities for use in daily wear and extended or continuous wear applications.

An apparatus is provided for removing matter from within a conduit. The apparatus generally comprises a separation edge attached to a wire at its proximal end, a frame attached to the distal end of the separation edge, and a membrane attached to the wire and disposed over the frame enclosing its interior. The membrane generally comprises a net constructed from a vaporized metal deposited on a mandrel. Alternatively, the membrane may comprise a braided tube constructed from wire. The apparatus may be employed as a filter or as a means for actively dislodging matter from the wall of a conduit. When employed as a filter, the apparatus is positioned downstream of the matter where it ensures that matter does not escape downstream as it is being removed. When employed to actively remover matter from a conduit, the apparatus is positioned downstream of the matter. The apparatus is then pulled proximally whereby it engages the matter and dislodges it from the wall of the conduit

When these two polyolefins were added to a thermoplastic vulcanizate (e.g. used to partially or fully replace the semicrystalline polyolefin of a thermoplastic vulcanizate), the thermoplastic vulcanizate was found to have the necessary adhesion to form fiber reinforced thermoplastic vulcanizate.

A multilayer balloon catheter is formed to have an inner layer and an outer layer, where the outer layer is adapted to resist shredding and premature rupture. The outer layer is formed of a material having a glass transition temperature that is lower than the transition or melting temperature of the inner layer. By forming the balloon on a mold at a temperature between the glass transition temperature of the outer layer and the glass transition or melting temperature of the inner layer, the outer layer will undergo a thermal relaxation that will alleviate some of the axial orientation of the polymer chains that develop during the formation of the multilayer balloon. This relaxation leads to a resistance to shredding when the balloon is expanded during operation.
