Surgical Extractor
US Patent:
6780193, Aug 24, 2004
Filed:
Mar 25, 2002
Appl. No.:
10/105985
Inventors:
Stephen W. Leslie - Lorain OH
James S. Bates - Bloomington IN
James S. Bates - Bloomington IN
Assignee:
Boston Scientific Corporation - Natick MA
International Classification:
A61B 1724
US Classification:
606114, 606127, 606200
Abstract:
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 an proximal end of the extractor 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 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.

Abstract:
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.
