  • Patent number: 10376254
    Abstract: A device for sealing a puncture opening may include a base frame having a delivery configuration wherein the base frame is retracted to have a relatively smaller overall profile, and a deployed configuration wherein the base frame is extended to have a relatively larger overall profile. The base frame is sized to engage an interior surface of the blood vessel wall in the deployed configuration. A sealing section is coupled to the base frame, the sealing section having an initial configuration wherein the sealing section permits fluid flow, and a barrier configuration wherein the sealing section prevents fluid flow. The sealing section in the barrier configuration is sized to block fluid flow through the puncture opening when the base frame is in the deployed configuration.

  • Patent number: 10376255
    Abstract: A system for sealing a large penetration in the wall of a femoral artery comprises an occlusion catheter and an applicator. An access catheter may further be provided in order to facilitate introduction of the occlusion catheter. The occlusion catheter is introduced through a contralateral penetration, advanced over the aortic bifurcation, and an occlusion element on the occlusion catheter is positioned at the large diameter penetration. The occlusion element is then inflated to temporarily seal the large penetration while blood perfusion past the occlusion element is provided by the catheter. A sealing material, such as a tissue adhesive or other hemostatic agent is then introduced into a tissue tract above the large diameter penetration in order to seal the penetration. The occlusion element may be left in place while the sealing material has time to set, cure or otherwise form a permanent seal of the large penetration. The occlusion catheter and all access sheaths may then be removed from the patient.

  • Publication number: 20140271472
    Abstract: Lung volume reduction by isolating a target lung portion from the rest of the lung with a mass of extracellular matrix (“ECM”) material. The procedure can be performed by locating a tube within the lumen of an airway to be obstructed and depositing an amount of flowable or other ECM in the open space until the lumen is occluded. Optionally, the procedure may be performed by delivering a plug substantially comprised of ECM material into the lumen of an airway to be obstructed. Further optionally, the ECM plug may include a one-way valve to allow air and mucous to escape from the isolated lung portion.

  • Patent number: 8821456
    Abstract: A medication delivery system for delivering medication to an internal body cavity through a natural body orifice that opens to the cavity has a pad for external placement against the body orifice and an elongated body that extends from the pad through the body orifice when the pad is externally placed against the body orifice. The elongated body carries medication and is long enough to deliver the carried medication to tissue forming the body cavity. The pad has a medication-holding zone surrounding the elongated body on an inner face of the pad and carrying medication that is delivered externally to tissue surrounding the body orifice concurrent with delivery of the medication carried by the elongated body to the tissue forming the body cavity.

  • Publication number: 20140188033
    Abstract: Implantable drug-doped component, e.g., a cochlear implant, including host material, a host-embedded drug, a sacrificial material integrated with the host. Sacrificial material facilitates release of drug from the component. Sacrificial material facilitates release through creation of voids in the host upon dissolution of sacrificial material upon contact with a solvent, e.g., perilymph fluid upon implant. Host can be polysiloxane, or silicone rubber. Drug can be anti-inflammatory, growth factor, antibody, anti-oxidant, antibiotic, corticosteroid. Sacrificial material can be: glucose monomer, sugar, cyclodextrin, dissolvable or resorbable at implant site, a salt, bioresorbable material, hyaluronic acid, polyurethane, polyester, polyamide, polyvinyl alcohol, polyacrylic acid. Sacrificial material can be the host, and can facilitate release of drug through changing a property of sacrificial material, e.g., by exposing component to ethanol wash.
