Lubricious coatings for medical devices and their uses are described.

The invention relates to intermittent catheters comprising a calixarene bonded to a surface thereof, in particular to provide a bacteria-repellent and/or lubricous coating on the outer surface of an intermittent catheter. The calixarene moiety may comprises hydrophilic surface groups to provide lubricity, whilst also providing a bacteria-repellent effect, especially useful preventing discomfort and/or infection for a user inserting multiple catheters per day.

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

This invention relates to comfortable ophthalmic devices and methods of producing such devices by treating unhydrated, polymerized ophthalmic lens with a polymeric wetting agent, wherein the ophthalmic lens formulation does not comprise said wetting agent prior to its polymerization.

The present invention relates to fatty acid-grafted hyaluronic acid (FA-g-HA), and a sterile microsphere-based dermal filler formulation and a sterile crosslinked hyaluronic acid-based dermal filler formulation each comprising the FA-g-HA. The present invention further relates to processes for the preparation of the FA-g-HA and the dermal filler formulations comprising the FA-g-HA, and their use in cosmetic applications.

Devices for preventing and/or otherwise inhibiting biofilm formation include a lumen and/or a cavity coupled with a wall configured for holding oils, which leach through the wall of the devices to a surface, the oils at the surface creating a smooth surface coating.

A new insight on the lubrication of joints is presented. Addition of small amounts of nanoscale diamond particles to a joint promotes a substantial improvement in friction and wear behavior of the joint surfaces. The joints can be artificial or natural joints.

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

The present disclosure relates to a polycaprolactone microsphere filler containing collagen peptide and a preparation method therefor. Provided is a polycaprolactone microsphere filler obtained by encapsulating collagen peptide in polycaprolactone microspheres, which, when injected into a living body, exhibits a rapid collagen formation effect as well as a high tissue restoration property and maintains the effects for a long period of time, thereby showing excellent restoration or volume expansion or wrinkle improvement properties of soft tissues such as cheeks, breasts, nose, lips, and buttocks.

There is described inter alia a device having a surface comprising a layered coating wherein the outer coating layer comprises a plurality of cationic hyperbranched polymer molecules characterized by having (i) a core moiety of molecular weight 14-1,000 Da (ii) a total molecular weight of 1,500 to 1,000,000 Da (iii) a ratio of total molecular weight to core moiety molecular weight of at least 80:1 and (iv) functional end groups, whereby one or more of said functional end groups have an anti-coagulant entity covalently attached thereto.
