  • Patent number: 9510976
    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.

  • Patent number: 9468707
    Abstract: The present invention is directed to polymeric materials made of biodegradable, bioabsorbable triblock copolymers and implantable devices (e.g., drug-delivery stents) containing such polymeric materials. The polymeric materials may also contain at least one therapeutic substance. The polymeric materials are formulated so as to improve the mechanical and adhesion properties, degradation, biocompatibility and drug permeability of such materials and, thus, implantable devices formed of such materials.

  • Publication number: 20160278952
    Abstract: Methods for making scaffolds for delivery via a balloon catheter are described. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold structure has patterns that include an asymmetric or symmetric closed cell, and links connecting such closed cells.

  • Patent number: 9452138
    Abstract: Formulations and methods are disclosed which provide controlled, sustained release of a biologic therapeutic to a space within the body. More specifically, formulations comprising a plurality of hydrophilic polymer strands, and methods of forming and administering such formulations, are disclosed. In some embodiments, the formulations exhibit a burst release, an initial release, a triphasic release, and release over thirty to ninety days of the biologic therapeutic. In some embodiments, the formulations exhibit reversible precipitation of the biologic therapeutic into precipitates having a diameter of about 50 nm to about 10 ?m.

  • Publication number: 20160270639
    Abstract: An endoscopy capsule having an image collecting capacity includes a deformable member configured to inflate when exposed to body liquid. The deformable member includes an effervescent material. When the effervescent reacts with water the resulting Carbon-Dioxide gas reduces the specific gravity of the endoscopy capsule. The capsule is contained within a shell or dome when swallowed. The shell or dome is configured dissolve in either a low or high pH environment.

  • Publication number: 20160175044
    Abstract: A catheter apparatus for treatment of a human patient is described, the catheter apparatus having a central axis and comprising a shaping structure moveable between a delivery state having a first helical shape, and a deployed state having a second helical shape. The shaping structure is configured to have a reverse taper with a structural diameter that varies over the length of the shaping structure such that the structural diameter of the shaping structure at the proximal end is smaller than the structural diameter of the shaping structure at the distal end.

  • Patent number: 9353218
    Abstract: Multifunctional compounds are provided that readily crosslink in situ to provide crosslinked biomaterials. The multifunctional compounds contain a single component having at least three reactive functional groups thereon, with the functional groups selected so as to be non-reactive in an initial environment and inter-reactive in a modified environment. Reaction of a plurality of the multifunctional compounds results in a three-dimensional crosslinked matrix. In one embodiment, a first functional group is nucleophilic, a second functional group is electrophilic, and at least one additional functional group is nucleophilic or electrophilic. Methods for preparing and using the multifunctional compounds, and kits including the multifunctional compounds are also provided. Exemplary uses for the multifunctional compounds include tissue augmentation, biologically active agent delivery, bioadhesion, and prevention of adhesions following surgery or injury.
