Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
A medical retrieval device, comprising: a sheath having a lumen, proximal end, and a distal end; a handle at the proximal end of the sheath; and an atraumatic basket for atraumatically removing material from a body, the basket having a collapsed position where the basket is enclosed within the sheath and an expanded position where the basket extends from the distal end of the sheath, the basket comprising two or more pairs of basket legs, each pair of basket legs formed from a single wire loop, and each pair of said basket legs crossing each other and being unattached and freely moveable with respect to each other at a distal end of the basket when said basket is in the collapsed position or the expanded position.
Claim 2
Dependent Claim
126 words
A medical retrieval device, comprising: a sheath having a lumen, proximal end, and a distal end; a handle at the proximal end of the sheath; and an atraumatic basket for atraumatically removing material from a body, the basket having a collapsed position where the basket is enclosed within the sheath and an expanded position where the basket extends from the distal end of the sheath, the basket comprising two or more pairs of basket legs, each pair of basket legs formed from a single wire loop, and each pair of said basket legs crossing each other and being unattached and freely moveable with respect to each other at a distal end of the basket when said basket is in the collapsed position or the expanded position.
Claim 3
Dependent Claim
15 words
The medical device of claim 1 wherein said basket comprises three pairs of basket legs.
Claim 4
Dependent Claim
46 words
The medical device of claim 1 wherein said sheath is movable over the basket, wherein said basket is in the collapsed position when the sheath is advanced over the basket, and said basket is in the expanded position when the sheath is retracted from the basket.
Claim 5
Dependent Claim
56 words
The medical device of claim 1 further comprising an elongated member, said elongated member axially moveable in said sheath lumen, said basket joined at a proximal end of said basket to the distal end of sa elongated member, wherein axial movement of said elongated member moves said basket between the expanded position and the collapsed position.
Claim 6
Independent Claim
162 words
A method for retrieving material from a body, comprising: inserting a retrieval device into said body, the retrieval device comprising a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and an atraumatic basket for atraumatically removing material from a body, the basket having a collapsed position where the basket is enclosed within the sheath, and an expanded position where the basket extends from the distal end of the sheath, the basket comprising two or more pairs of basket legs, each pair of basket legs formed from a single wire loop, and each pair of said basket legs crossing each other and being unattached and freely moveable with respect to each other at a distal end of the basket when said basket is in the collapsed or the expanded position; atraumatically capturing the material within the basket; and withdrawing the retrieval device from the body to remove the captured material from the body.
Claim 7
Independent Claim
162 words
A method for retrieving material from a body, comprising: inserting a retrieval device into said body, the retrieval device comprising a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and an atraumatic basket for atraumatically removing material from a body, the basket having a collapsed position where the basket is enclosed within the sheath, and an expanded position where the basket extends from the distal end of the sheath, the basket comprising two or more pairs of basket legs, each pair of basket legs formed from a single wire loop, and each pair of said basket legs crossing each other and being unattached and freely moveable with respect to each other at a distal end of the basket when said basket is in the collapsed or the expanded position; atraumatically capturing the material within the basket; and withdrawing the retrieval device from the body to remove the captured material from the body.
Claim 8
Dependent Claim
16 words
