  • Patent number: 11969500
    Abstract: The present technology relates to depots for the treatment of postoperative pain via sustained, controlled release of a therapeutic agent. In some embodiments, the depot may comprise a therapeutic region comprising an analgesic, and a control region comprising a bioresorbable polymer and a releasing agent mixed with the polymer. The releasing agent may be configured to dissolve when the depot is placed in vivo to form diffusion openings in the control region. The depot may be configured to be implanted at a treatment site in vivo and, while implanted, release the therapeutic agent at the treatment site for no less than 3 days.

  • Publication number: 20200368398
    Abstract: The devices, systems, and methods disclosed herein may be directed to a delivery system including a therapeutic member configured for endoluminal placement via the delivery system into the esophagus of the patient, wherein the therapeutic member comprises a treatment portion comprising a film for controlled release of a chemotherapeutic agent. The film may comprise a control region, a therapeutic region, and a substantially impermeable base region. The film is configured to release the chemotherapeutic agent in a direction away from the substantially impermeable base region. The delivery system is configured to enable a treatment provider to position the treatment portion of the therapeutic member proximate to a treatment site associated with the esophagus of the patient, and the therapeutic member is configured to administer a therapeutically effective dose to the treatment site for a sustained period following endoluminal placement of the therapeutic member.

  • Patent number: 9451978
    Abstract: An expandable cage is expanded within a narrowed region of a blood vessel. The expandable cage has openings therein so that plaque protrudes through the openings when the cage is expanded. A material removing element passes within the cage to remove the plaque extending into the openings. The openings are preferably formed by integrally formed elements which provide a smooth internal surface. The material removing element passes along the smooth internal surface when removing the plaque. A collection bag is coupled to the material removing element to capture the material which has been removed.

  • Patent number: 8535301
    Abstract: The invention provides surgical systems and methods for ablating heart tissue within the interior and/or exterior of the heart. A plurality of probes is provided with each probe configured for introduction into the chest for engaging the heart. Each probe includes an elongated shaft having an elongated ablating surface of a predetermined shape. The elongated shaft and the elongated ablating surface of each probe are configured to ablate a portion of the heart. A sealing device affixed to the heart tissue forms a hemostatic seal between the probe and the penetration in the heart to inhibit blood loss therethrough.
