Abstract
A device includes a tube and a filament. The tube has a first end, a second end, and a center axis disposed between the first end and the second end. The filament is disposed at the first end and having a portion configured as a loop aligned on an extension of a lumen of the tubular segment. A portion of the filament is configured for axial movement within the lumen.
Claims22
A device for blunt dissection of a tissue comprising:
- a tube having a first end, a second end, and a center axis disposed between the first end and the second end;
- and
- a filament disposed at the first end and having a portion configured as a loop aligned on an extension of a lumen of the tube, wherein a portion of the filament is configured for axial movement within the lumen, wherein the loop has an edge that is blunt for the blunt dissection of the tissue;
- wherein the filament lies substantially in a plane, and wherein the plane is disposed at an oblique angle relative to the center axis;
- and
- wherein the axial movement of the filament along the center axis relative to the tube causes the plane to raise and lower without a change in the oblique angle.
3 more elements
A device for blunt dissection of a tissue comprising:
- a tube having a lumen on a longitudinal axis;
- a filament having a first end and a second end separated by a segment and configured for movement in a first direction aligned parallel with the longitudinal axis and at least a first portion of the filament disposed in the lumen;
- and
- wherein the segment is clear of the lumen and configured as a loop;
- wherein the segment for the loop has an edge that is blunt for the blunt dissection of the tissue;
- and
- wherein elasticity of the filament in a second direction aligned parallel to a plane of the segment is less than elasticity of the filament in a third direction aligned normal to the plane.
