Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
49 words
A non-reflective surgical instrument comprising: a surgical instrument metallic substrate; and a non-reflective coating comprising of a mixture of about 60% Al 2 O 3 and about 40% TiO by weight deposited on said instrument by a detonation gun process and rendering said instrument substantially non-reflective of infrared radiation.
Claim 2
Dependent Claim
49 words
A non-reflective surgical instrument comprising: a surgical instrument metallic substrate; and a non-reflective coating comprising of a mixture of about 60% Al 2 O 3 and about 40% TiO by weight deposited on said instrument by a detonation gun process and rendering said instrument substantially non-reflective of infrared radiation.
Claim 3
Dependent Claim
36 words
A non-reflective surgical instrument comprising: a surgical instrument metallic substrate; and a non-reflective coating comprising a Al 2 O 3 /TiO mixture deposited on said substrate, said coating rendering said instrument substantially non-reflective of infrared radiation.
Claim 4
Dependent Claim
36 words
A non-reflective surgical instrument comprising: a surgical instrument metallic substrate; and a non-reflective coating comprising a Al 2 O 3 /TiO mixture deposited on said substrate, said coating rendering said instrument substantially non-reflective of infrared radiation.
Claim 5
Dependent Claim
24 words
The instrument of claim 2 wherein said Al 2 O 3 /TiO mixture is about 60% Al 2 O 3 and about 40% TiO.
