    摘要: A surgical extractor, and related method, for removing material (such as calculi and stones) from the body has the ability to capture and release material. The extractor has a sheath, a basket comprised of a plurality of legs that are unattached at a distal end of the basket and joined at a proximal base of the basket, and a plunger at the distal end of the sheath. The legs are movable relative to the sheath to achieve a collapsed position within the sheath and an extended position outside of the sheath in the form of an open basket. The plunger can be moved back and forth between a withdrawn position against the distal end of the sheath with the basket legs in the open position and an extended position away from the distal end of the sheath with the basket legs in a closed position. The distal ends of the legs are farther apart from each other when in the open position than when in the closed position.

    摘要: A medical device for removing an object from a body includes a retrieval basket having a distal section and a proximal section, at least two strands extending through the proximal section of the retrieval basket, and at least three prestressed filaments extending from a distal end of each of the at least two strands through the distal section of the retrieval basket. The filaments are spaced from each other through the entire distal section of the retrieval basket between a proximal end of the filaments and a distal end of the filaments. The filaments also converge at a distal end of the distal section of the retrieval basket, and the filaments are entwined to form each of the at least two strands.

    摘要: A surgical extractor for removing objects from a body including, for example, calculi, such as kidney stones and gall stones. The extractor includes a handle at a proximal end with a slider for operation by a physician. At the distal end, the extractor includes a plurality of wires with each wire comprising a first portion having an individual strand and a second portion comprising a plurality of filaments. When a retaining sheath is retracted, the wires, formed of a shape memory material such as stainless steel, expand such that each of the strands assume a spaced relationship to define a first section of a basket and the plurality of the filaments assume a spaced relationship to define a second section of the basket. The use of a basket formed by wires having a first section comprising an individual strand and a second section comprising the plurality of filaments promotes capture of objects within the body by having widely spaced wires in the first section, retention of such objects in the second section by multiplying the number of contacts with entrapped object, and improved selective release of such objects without any deleterious effect on the reliability or size of the extractor. Additionally, use of the basket enables improved dislodgment and capture of embedded or impacted objects.

    摘要: Grasping an object, e.g., a calculus in the biliary tract, using a grasper, such as a basket, that can be opened and closed without mechanical advantage and also rotated about the device axis to make it easier to capture the object. The basket can then be closed further with mechanical advantage to crush the object.

    摘要: A sheath defines a lumen. A mesh portion is coupled to the sheath and is movable between a retracted position and an expanded position. An elongate member is disposed in the lumen and is operably attached to one of the mesh portion and the sheath such that longitudinal movement of the elongate member within the lumen causes movement of the mesh portion between the expanded position and the retracted position. The sheath and the mesh portion are introduced into the body along with an end effectuator. The mesh portion is moved to its expanded position to form an object supporting surface. The surface is used to support an object, such as a stone, during a medical treatment procedure using the end effectuator.
