Disclosed is a medical device having an elastic modulus of 100 kPa or more and 2,000 kPa or less, a water content of 10% by mass or less, a tensile elongation of 50% or more and 3,000% or less, and a dynamic contact angle (advancing angle) relative to a borate buffer of 80&#xb0; or less. The present invention can significantly reduce or avoid a phenomenon of adhesion to a surface when contacted with a surface outside or inside the body, which has hitherto been regarded as a problem in a conventional medical device.

Medical device, combination of coating solutions, and method for producing medical device

In order to provide an electrode equipped with an insulating wall having excellent patterning properties as well as excellent biocompatibility, there is provided an electrode including, on a substrate, an electrode element; and an insulating wall formed around the electrode element, constituted of a polysiloxane compound (component A) having, per molecule, two or more functional groups selected from the group consisting of a (meth)acryloyl group, a styrenic vinyl group, a vinyl ester group, a maleic acid ester group and a maleimide group, and formed from a polymer obtained by reaction of the functional groups.

Electrode and method for manufacturing electrode

The present invention relates to a silicone acrylamide copolymer of high acrylamide monomer content which has transparency and low modulus, employing the following configuration. The copolymer is suitably used for various kinds of medical devices, particularly ophthalmic lenses such as a contact lens, an intraocular lens, an artificial cornea, and is especially suitable for a contact lens. A copolymer comprising (A) a multi-functional (meth)acrylamide monomer having at least one siloxane bond and at least two (meth)acrylamide groups within a molecule and (B) a mono-functional linear silicone (meth)acrylamide monomer.

Silicone acrylamide copolymer

The present invention relates to macroinitiators comprising at least one hydrophobic segments in a molecule, wherein a molecular weight of the hydrophobic segment is 300 to 1800. The present invention further relates to block copolymers, wetting agent and polymeric materials having the block copolymers of the present invention associated with, which is suitable for medical devices, particularly for ophthalmic devices, including contact lenses, ophthalmic lenses, punctal plugs and artificial corneas.
