Patent ID: 8808323

Claim:
An attachment configuration disposed at a proximal end of a filter member comprising: a. a catheter body coaxially disposed through the proximal end of the filter member; b. a plurality of cutouts disposed coaxially around the proximal end of the filter member; and c. a thin tube coaxially disposed around the plurality of cutouts, wherein the thin tube engages the at least a portion of the catheter body and the thin tube fixedly attaches the proximal end of the filter member through the plurality of cutouts; wherein the material of the thin tube and the material of the catheter body is the same as to be fused together through the plurality of cutouts; wherein the plurality of cutouts include a width W extending generally along the longitudinal axis of the proximal end and a height H extending generally along the axial axis of the proximal end, wherein the width W of the cutouts is greater than the height H of the plurality of cutouts; wherein the plurality of cutouts are longitudinally disposed throughout the proximal end of the filter member to provide at least two longitudinal rows of cutouts wherein the at least two longitudinal rows of cutouts is a first row of longitudinal cutouts and a second row of longitudinal cutouts; the first longitudinal row of cutouts is a repeating pattern of semi-circular shape cutouts, whereby the semicircular shape cutouts include a first leg and a second encircling the semi-circular cutout; the second longitudinal rows of cutout includes a repeating pattern of diamond shaped cutouts, whereby the diamond shaped cutouts include a strut-like enclosure with a top half and a bottom half enclosing the diamond shaped cutouts; and the top half and the bottom half of the diamond-shaped cutouts are fixedly attached to the first legs of the semi-circular cutouts.
