Appeal No. 2001-2074
Application 08/552,143
REJECTIONS
Claims 1 through 5 and 8 stand rejected under 35 U.S.C.
§ 103 as unpatentable over Daum. According to the examiner, Daum
discloses an outer straight tube or cannula, middle interior tube
which is of superelastic material and normally curved, and an
inner stylet tube. The examiner takes official notice of the
fact that bevelled medical instruments are known in the art. The
examiner is of the opinion that it would have been obvious to
bevel the outer and middle tubes of Daum to reduce injection site
tissue trauma.
Claims 9 through 18 stand rejected under 35 U.S.C.
§ 103 as unpatentable over Daum in view of Hillstead. The
examiner is of the opinion that Hillstead shows handles on the
proximal end of the tube and the use of a stopper device. The
examiner is of the opinion that it would have been obvious to
provide Daum with handles for the tubes of Daum and to provide a
stopper device in the Daum invention.
