  • Publication number: 20170027724
    Abstract: A polymeric stent can be implanted for treatment of the Eustachian tube. The stent can be designed to have length-dependent radial strength to allow it to stay within the Eustachian tube and to allow normal closing and opening of the Eustachian tube. A balloon can be used to implant the stent, and the balloon can be coated with a therapeutic agent. A coated balloon can also be used to transfer therapeutic agents to the sinus cavity during a balloon sinus dilation procedure.

  • Patent number: 9498359
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold has a structure that produces a low late lumen loss when implanted within a peripheral vessel and also exhibits a high axial fatigue life. In a preferred embodiment the scaffold forms ring structures interconnected by links, where a ring has 12 crowns and at most two links connecting adjacent rings.

  • Publication number: 20160199065
    Abstract: A medical device that can be wrapped around a segment of an artery downstream of an arteriovenous fistula. The wrap, when used in this manner, creates a stenosis for reducing retrograde flow at the fistula. Sutures are positioned in holes present in the upper and lower halves or connecting ends of the wrap, after which the sutures are pulled to oppose the two sides in order to create a stenosis. When the surgeon is satisfied that the stenosis is appropriate, the sutures are tied in place.

  • Patent number: 9289318
    Abstract: A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.

  • Patent number: 9173890
    Abstract: A method including advancing a delivery device through a lumen of a blood vessel to a particular region in the blood vessel; and introducing a composition including a sustained-release carrier and an apolipoprotein A-I (apo A-I) synthetic mimetic peptide into a wall of the blood vessel at the particular region or a perivascular site, wherein the peptide has a property that renders the peptide effective in reverse cholesterol transport. A composition including an apolipoprotein A-I (apo A-I) synthetic peptide, or combination of an apo A-I synthetic mimetic peptide and an Acyl CoA cholesterol: acyltransferase (ACAT) inhibitor in a form suitable for delivery into a blood vessel, the peptide including an amino acid sequence in an order reverse to an order of various apo A-I mimetic peptides, or endogenous apo A-I analogs, or a chimera of helix 1 and helix 9 of endogenous apo A-I.
