Benefits of technology

The present invention provides a method and apparatus for deploying and retrieving an IVC filter through a single catheter system. This allows for easy repositioning of the filter and retrieval without the need for additional components or equipment. The method can be used with filters made from flexible materials such as absorbable filaments, polymers, or metal alloys. The invention also allows for efficient retrieval of absorbable filters before they have been absorbed in the IVC. Overall, the invention provides a convenient and efficient way to manage IVC filters during deployment and retrieval.

Problems solved by technology

Moreover, these prior art devices generally cannot be retrieved without a separate retrieval system that often requires jugular access.

Abstract

The present invention relates generally to a method and apparatus for deploying and / or retrieving an object (e.g., a vena cava filter) in a cavity (e.g., a vena cava) using a system configured to: (i) maintain grip of the unsheathed object in the cavity until deliberately released, (ii) prevent premature release of the object in the cavity, and / or (iii) facilitate retrieval by first everting said object, then withdrawing the object through a guiding catheter (e.g., retrieval via eversion).

RELATED PATENT APPLICATIONS[0001]This application is a continuation application of U.S. application Ser. No. 15 / 592,043 filed May 10, 2017, which is a continuation application of U.S. application Ser. No. 15 / 586,210 filed May 3, 2017, which claims priority to U.S. Provisional Application Ser. No. 62 / 331,291, filed May 3, 2016, all of which are herein incorporated herein by reference in their entireties.FIELD OF THE INVENTION[0002]The present invention relates generally to a method and apparatus for delivering and retrieving an object (e.g., a vena cava filter) in a cavity.BACKGROUND OF THE INVENTION[0003]Between 100,000 to 300,000 Americans die annually from pulmonary embolism (PE), which is more than breast cancer, AIDS, and traffic fatalities combined. PE is the 3rd leading cause of death in the United States. A similar incidence of PE is found in Europe with approximately 370,000 annual deaths. Moreover, PE is the third most common cause of death in trauma patients that survive t...
