Abstract
Abstract A combination suture-needle assembly wherein the suture diameter and the maximum needle diameter are preferably the same or the suture diameter may be less than the needle diameter. The needle is secured to the suture by means of a needle shank portion of smaller diameter than the maximum needle diameter, the shank being inserted into an internal or central bore provided in the suture, the needle being suitably anchored therein. The remaining length of the suture bore may be left empty, or it may be filled by pigments, tissue-reactive fluids, suture solvents, or other active or inert materials.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
In combination, a suture and needle joined together, the suture comprising a length of monofilament having an internal bore and having an external predetermined peripheral shape of predetermined first dimensions; the needle comprising a needle end portion and a shank end portion, the needle end portion extending from a point at one end thereof to a shoulder at the other end thereof, the periphery of the needle at the shoulder having the same shape as said first peripheral shape and having corresponding cross-sectional dimensions no less than said first dimensions; the shank end portion extending from the shouldered end of the needle end portion and being of predetermined dimensions and shape smaller than the external dimensions of the suture, said shank end portion being inserted into and held in said bore with the end of the suture abutting said shoulder in close engagement therewith.
Claim 2
Dependent Claim
144 words
In combination, a suture and needle joined together, the suture comprising a length of monofilament having an internal bore and having an external predetermined peripheral shape of predetermined first dimensions; the needle comprising a needle end portion and a shank end portion, the needle end portion extending from a point at one end thereof to a shoulder at the other end thereof, the periphery of the needle at the shoulder having the same shape as said first peripheral shape and having corresponding cross-sectional dimensions no less than said first dimensions; the shank end portion extending from the shouldered end of the needle end portion and being of predetermined dimensions and shape smaller than the external dimensions of the suture, said shank end portion being inserted into and held in said bore with the end of the suture abutting said shoulder in close engagement therewith.
