Embodiment Construction

[0050]Example embodiments that incorporate one or more aspects of the present invention are described and illustrated in the drawings. These illustrated examples are not intended to be a limitation on the present invention. For example, one or more aspects of the present invention can be utilized in other embodiments and even other types of devices. Moreover, certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. Still further, in the drawings, the same reference numerals are employed for designating the same elements.

[0051]A blood vessel extraction device may be configured to include multiple engagement members that extend laterally and / or radially outward from the device body (relative to the length of the blood vessel) upon actuation. The multiple engagement members may be configured to cut and / or engage a portion of the blood vessel so that the blood vessel may be extracted upon removal of the extraction device. T...

Abstract

A device and method for extracting tubular structures are provided. An incision is made at a proximate and at a distal end of a tubular structure. An extracting device is inserted into and passed through a tubular structure until the operational head of the device extends past the distal incision. An actuator on the handle of the device is actuated, longitudinally extending the operational head of the device. The edge of a tubular structure is positioned axially in the mouth of a hook wire on the operational head. The actuator on the handle is released and the hook wire engages and captures the tubular structure. The user manually pulls the tubular structure, invaginating and removing it.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims benefit of U.S. Provisional Application Ser. No. 61 / 263,531, filed on Nov. 23, 2009, and U.S. Provisional Application Ser. No. 61 / 313,899, filed on Mar. 15, 2010, the disclosures of which are incorporated by reference in their entireties.FIELD OF THE INVENTION[0002]The present invention relates generally to an extractor device and method for removing tubular body members, such as blood vessels, from the body of a human or animal.BACKGROUND OF THE INVENTION[0003]Tubular body members generally include blood vessels (such as arteries and veins), tendons, bile ducts and other generally tubular structures found or used within a human or animal body. Such tubular structures are sometimes removed, either for use somewhere else in the body or simply because removal is desired or necessary. For example, the long sapheneous vein (LSV), located in subcutaneous fatty tissue in an anteromedial compartment of the lower leg...
