  • Patent number: 8802121
    Abstract: Silane-functionalized hydrophobic ?(1?4)glucopyranose polymers and polymeric matrices are described. Biodegradable matrices can be formed from hydrophobic ?(1?4)glucopyranose polymers with reactive pendent silyl ether groups. Reaction of the silyl ether groups provides improved matrix formation through bonding to a device surface of a device, polymer-polymer crosslinking, or both. Biodegradable matrices can be used for the preparation of implantable and injectable medical devices, including those that release a bioactive agent.

  • Patent number: 8795711
    Abstract: An implant for insertion into a punctum of a patient comprises a body. The body has a distal end, a proximal end, and an axis therebetween. The distal end of the body is insertable distally through the punctum into the canalicular lumen. The body comprises a therapeutic agent included within an agent matrix drug core. Exposure of the agent matrix to the tear fluid effects an effective therapeutic agent release into the tear fluid over a sustained period. The body has a sheath disposed over the agent matrix to inhibit release of the agent away from the proximal end. The body also has an outer surface configured to engage luminal wall tissues so as to inhibit expulsion when disposed therein. In specific embodiments, the agent matrix comprises a non-bioabsorbable polymer, for example silicone in a non-homogenous mixture with the agent.

  • Patent number: 8703168
    Abstract: An implantable medical device for releasing therapeutic agent having a medical device body and a plurality of reservoir-defining structures disposed on a surface of the body. A reservoir can be defined by the reservoir-defining structures and therapeutic agent may be located in the reservoir. A cover may extend over the reservoir so that the therapeutic agent is released from the reservoir when the medical device implanted. Methods for making the medical device may also include providing a medical device body, positioning a plurality of reservoir-defining structures on a surface of the body to form a reservoir, loading therapeutic agent into the reservoir, and covering the reservoir so that the therapeutic agent may release when the medical device is implanted. Alternatively, the reservoir may be covered with a cover and an opening formed in the cover so that the therapeutic agent may release when the medical device is implanted.

  • Patent number: 8691258
    Abstract: Implantable medical devices (IMDS) having anti-infective properties are described. Anti-infective agents are disposed in, on, or about at least a portion of a surface of the medical device. The anti-infective agents are disposed in or on a vehicle, which may be in the form of a coating layer or covering. The vehicle may be biodegradable so that, over time, the anti-infective agent is removed from a tissue location into which the device is implanted, reducing the likelihood that microorganisms resistant to the anti-infective agent will develop. IMDs having an anti-infective agent and an anti-activity agent disposed therein, thereabout, or thereon are also described. The anti-activity agent interferes with the activity of the anti-infective agent, may be released from a surface at the IMD at a time when activity of the anti-infective agent is no longer desired, and may reduce the likelihood that microorganisms resistant to the anti-infective agent will develop.
