案情简介A公司于1998年9月1日对名称为“预制导管导引的闭塞器械”的发明专利提出了国际申请。该申请于2000年3月6日进入中国国家阶段,于2002年10月2日经国家知识产权局公告授权。该发明专利授权时的权利要求书只有一项独立权利要求,即“一种预制导管导引的闭塞器械,包含一金属编制品,其具有预设扩展的外形。在该预设扩展的外形的每个近端和远端包含一凹槽,所述每个近端和远端具有一装置,其用于固定附着到金属编制品上的每一端部,该装置容纳在凹槽内部。其中,所述医疗器械的形状能闭塞异常开口,因此,所述预设扩展的外形可变形为较小断面形状,用以输送通过病人体内的液流管。该金属编制品具有记忆特性,当不加约束时,医疗器械往往返回到所述预设扩展的外形。”
Case Briefing Company A filed an international application on September 1, 1998 for an invention patent entitled “Prefabricated Catheterized Occlusion Apparatus”. The application entered into the national phase of China on March 6, 2000 and was authorized by the State Intellectual Property Office on October 2, 2002. The patent claims at the time of the invention patent have only one independent claim, namely “a prefabricated catheter-guided occlusion device comprising a metal product having a preset expanded profile. In the preset expanded profile Each of the proximal and distal ends includes a recess, each of the proximal and distal ends having a means for securing each end affixed to the metal article, the means being received within the recess, The shape of the medical device being able to occlude the anomalous opening such that the preset expanded profile is deformable into a smaller cross-sectional shape for delivery through a fluid conduit in the patient’s body The metal article has a memory property that when worn When constrained, the medical device tends to return to the preset expanded shape. ”
