FAQ
The clinically important degree of stenosis is considered the percentage of stenosis that corresponds to a substantial increased risk for stroke. The USPSTF recommendations3 consider 60 to 99 percent stenosis to be clinically important.
A grade of patent without stenosis was given to any vessel displaying no or only minor disturbances in color-flow characteristics and no stenoses of ≥50%. A grade of patent with stenosis was assigned to any vessel displaying moderate or severe disturbances in color-flow characteristics and a stenosis of ≥50%.
Significant stenosis was defined as 50%or greater. Lesions in the anterolateral, posterior left ven- tricular and marginal branches of the three major cor- onary arteries were only defined as obstruction of their. associated major vessels if the branches were large.
Jiang et al have reported the largest series of patients (42 stenoses in 40 patients) treated with stenting for M1 stenosis. The technical success rate of stenting was 97.6% for the lesions and 97.5% for the 40 patients.
Significant Stenosis Defined as. 75% or Greater Narrowing. The distribution of patients with no, one-, two- and. three-vessel and LMCA disease when significant.
Surgery is usually advised for carotid narrowing of more than 70%. Surgical treatment decreases the risk for stroke after symptoms such as TIA or minor stroke. Surgical treatment of carotid artery stenosis includes: Carotid endarterectomy (CEA).
These organizations suggest that stenoses above 50% should be graded within a range (i.e., 50–69% or 70% to near occlusion) to provide adequate information for clinical decision making.
Obviousness: The patent office will conduct a search for prior art, which is any previous disclosure of the invention or similar invention. If prior art is found, the patent application may be rejected. Lack of novelty: The invention must be new and non-obvious in order to be eligible for a patent.
By far the most frequent ground of rejection is on the ground of unpatentability in view of the prior art, that is, that the claimed subject matter is either not novel under 35 U.S.C. 102, or else it is obvious under 35 U.S.C.
Patent applications: the three criteria Novelty. This means that your invention must not have been made public – not even by yourself – before the date of the application. Inventive step. This means that your product or process must be an inventive solution. Industrial applicability.
