Abstract: A prosthetic heart valve includes a plurality of synthetic polymeric leaflets. Each leaflet has a base polymer and a polymer coating at least partially disposed over the base polymer, wherein the polymer coating includes polymerized units of a monomer comprising a zwitterionic group when the polymer coating is exposed to an aqueous environment at a pH of about 7.4.

Abstract: The present disclosure is directed to a delivery catheter with a mechanism of discharging an adhesive during and/or immediately prior to deployment of the medical device by the delivery catheter.

Abstract: An intravascular catheter is disclosed that includes an elongated shaft defined by a wall including at least one port extending through the wall into a lumen. At least one channel may be defined between layers of polymer making up the catheter shaft. The channel extends along at least a portion of the shaft and is in fluid communication with the port. Outer and inner diameters of the catheter may be substantially constant along the length of the catheter.

Abstract: Provided are ingestible polymeric formulations for the reduction of gastric volume in the treatment of overweight patients, and methods of use thereof. One method involves ingesting one or more ingestible tablets comprising cross-linked polymers formed in a packed mass within the one or more ingestible tablets into a stomach of the subject, wherein the cross-linked polymers comprise a polymer hydrogel comprising carboxymethylcellulose and a carboxylic acid; disintegrating an acid-sensitive gelatin coating such that the coating disintegrates in the gastric fluid and the cross-linked polymers disperse in the stomach; and maintaining the reduction in gastric volume such that a sensation of fullness is induced in the subject without releasing a drug which induces the sensation.

Abstract: Provided are ingestible polymeric formulations and oral dosage forms for the reduction of gastric volume in the treatment of overweight and obese patients. The formulation includes an acid-sensitive, gelatin coating over a dehydrated hydrophilic polymer. When ingested, the acid-sensitive coating is quickly dissolved by gastric secretions and the hydrophilic polymer is exposed to the aqueous environment of the gastric milieu. The polymer absorbs water and expands to the point that will not allow the polymer to pass beyond the pyloric valve, and the expanded polymer is therefore trapped in the stomach.
