Claim Text:
1. An implantable grasper for closure of an opening in a body vessel wall, comprising: a grasping member comprising an integral tubular member having a proximal portion and a distal portion, said proximal portion comprising a generally tubular body and a proximal end, and said distal portion comprising a plurality of fingers extending radially from a distal end of said body at a first angle, and collapsible therefrom to a second angle, said fingers being defined by slits through said tubular member, wherein said fingers extend integrally from said tubular body, said fingers having a generally rectangular cross-section defined by a thickness and a width where said width is larger than said thickness, said width being defined by said slits and said thickness being defined by inner and outer surfaces of said tubular member, said fingers having a distal tip configured to non-piercingly grasp an outer wall portion of said body vessel surrounding said opening when said fingers are extended at said first angle, said distal tip including two generally flattened portions at a leading end thereof and a groove disposed between the generally flattened portions, said generally flattened portions each comprising a distally facing end surface defined by at least a portion of said rectangular cross-section; and a locking member slidably received over a portion of said grasping member, the locking member movable along the fingers to collapse said fingers from said first angle to said second angle to cause said collapsed fingers to at least substantially close said vessel opening, said grasping member and said locking member being formed from a bioabsorbable composition.
