Abstract
Abstract Elongated, flexible strip, for linear or tubular surgical joinder has pluralities of primary retaining pins that extend in opposed directions and are substantially parallel to the strip face. The pins are adapted to pierce a respective tissue, extend therealong, and then extend into the opposed tissue of a surgical opening. Short retaining pins extending normal to the strip are adapted to inhibit withdrawal of the primary retaining pins. Apertures at one end of the strip operatively associate with end ones of the short pins to configure the strip for anastomosis.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
215 words
Surgical closure means comprising: a relatively thin, flexible, and manipulable ribbon comprised of a material that is compatible with the associated tissue whereat closure is to be effected; a first and second plurality of longitudinally aligned, spaced, generally parallel retaining pins extending in opposed directions, from and transversely across the ribbon's face that is to be operatively associated with said tissue; each plurality of said pins extending from a respective longitudinal side of said face to substantially the other longitudinal side of said face; each pin of said one plurality of pins being in a spaced and alternate relationship with respect to the opposed, said second plurality of pins; and each of functionally operative portions of said transversely extending pins being closely spaced from, and substantially parallel to, said face; whereby said surgical closure may be effected by manipulating and flexing said ribbon along the axial extent thereof and, by further manipulation, said first plurality of retaining pins is adapted to pierce said tissue on one side of the opening to be surgically closed, extend within the tissue on said one said and into the tissue on the opposed tissue side, and subsequently the opposed plurality of pins pierce the opposed tissue side, extend within opposed tissue and into the tissue on said one side.
Claim 2
Dependent Claim
215 words
Surgical closure means comprising: a relatively thin, flexible, and manipulable ribbon comprised of a material that is compatible with the associated tissue whereat closure is to be effected; a first and second plurality of longitudinally aligned, spaced, generally parallel retaining pins extending in opposed directions, from and transversely across the ribbon's face that is to be operatively associated with said tissue; each plurality of said pins extending from a respective longitudinal side of said face to substantially the other longitudinal side of said face; each pin of said one plurality of pins being in a spaced and alternate relationship with respect to the opposed, said second plurality of pins; and each of functionally operative portions of said transversely extending pins being closely spaced from, and substantially parallel to, said face; whereby said surgical closure may be effected by manipulating and flexing said ribbon along the axial extent thereof and, by further manipulation, said first plurality of retaining pins is adapted to pierce said tissue on one side of the opening to be surgically closed, extend within the tissue on said one said and into the tissue on the opposed tissue side, and subsequently the opposed plurality of pins pierce the opposed tissue side, extend within opposed tissue and into the tissue on said one side.
Claim 3
Dependent Claim
99 words
Surgical closure means as in claim 1, wherein: a plurality of spaced, longitudinally aligned, relatively short retaining pins extends generally normal to said face of the ribbon and along each said opposite, respective longitudinal side of said face; and each of said short retaining pins being disposed intermediate a pair of said oppositely, transversely extending pins; whereby said surgical closure is enhanced by said relatively short retaining pins extending at least partially into said tissue in a direction that is generally normal to that of said transversely extending pins to thus inhibit withdrawal motion of said latter retaining pins.
Claim 4
Dependent Claim
15 words
Surgical closure means as in claim 2, wherein said relative short pins are transversely aligned.
Claim 5
Dependent Claim
130 words
Surgical closure means as in claim 3, wherein: a plurality of spaced apertures are disposed along each said longitudinal side of said face; said apertures being in longitudinal alignment with its associated plurality of said normally extending pins; each aperture of one said plurality being in transverse alignment with a respective aperture of the second plurality; each said aperture being intermediate successive ones of said normally extending pins and intermediate a pair of said oppositely transversely extending pins; and said apertures and normally extending pins being dimensionally operative associated; whereby said ribbon means, in surgical closure configuration, may be retained in annular form by associating an end pair of said normally extending pins with an end pair of said apertures and thereby effect anastomosis of members with their intima opposed.
