Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
69 words
A surgical needle comprising a curved body portion terminating in one direction in a blunt end and in the other direction in a pointed end section, said pointed end section being laterally offset from said curved body portion, said curved body portion and said pointed end section together forming substantially no more than 180 degrees of arc and said pointed end section is offset 5 degrees to 60 degrees.
Claim 2
Dependent Claim
69 words
A surgical needle comprising a curved body portion terminating in one direction in a blunt end and in the other direction in a pointed end section, said pointed end section being laterally offset from said curved body portion, said curved body portion and said pointed end section together forming substantially no more than 180 degrees of arc and said pointed end section is offset 5 degrees to 60 degrees.
