## 特征比对表格

技术特征描述及公开性判断对比文件原文引用(翻译)公开性论述
技术特征A:细长主体,其限定第一管腔并且包括远侧部分<br>《直接公开》对比文件第[2]段:“The elongate member 26 can be percutaneously positioned in the cardiovascular system of a patient via a remote site such as the femoral artery so the distal end of the elongate member is located in or close to the remote site while a proximal end extends out the body of the patient.”;以及“the elongate member 26 comprises a tubular sheath 80 having a distal portion 82 that can be positioned in a coronary artery and a proximal portion 84 that extends out of the body of the patient.” 对比文件第[2]段:“In the preferred embodiment, the sheath 80 has an external diameter of 0.040 inch.” 以及“the sheath 80 is formed of a TPX material, specifically a methylpentene copolymer plastic.”对比文件明确公开了细长主体(elongate member 26或sheath 80),该主体限定管腔(lumen 86,即第一管腔)并具有远侧部分(distal portion 82),用于插入血管。该结构特征与目标专利的细长主体在结构上完全相同,作用均为提供导管通道。本领域技术人员可直接且毫无疑义地确定对比文件公开了该技术特征。
技术特征B:内部构件,其被配置用于插入到所述第一管腔中<br>《直接公开》对比文件第[2]段:“the drive cable 28 is installed into the sheath 80 via the main port 89.”;以及“the drive cable 28 and sensor assembly 24 are located in the flexible elongate member 26.” 对比文件第[2]段:“the drive cable 28 is positioned inside the elongate member 26 and is connected to the sensor assembly 24.”对比文件中的驱动电缆(drive cable 28)及其连接的传感器组件(sensor assembly 24)作为内部构件,被明确描述为插入并容纳于细长主体(鞘管80)的管腔(lumen 86)中。该内部构件可旋转或移动,与目标专利中内部构件插入第一管腔的作用相同。本领域技术人员可直接确认对比文件公开了该特征。
技术特征C:内部构件包括被配置为将治疗能量递送到处置部位并且中断身体管腔中的阻塞的声学能量源<br>《未公开》无相关引用对比文件中的声学能量源(超声换能器)仅用于成像(发射和接收超声脉冲以获取图像),未公开任何关于治疗能量递送或中断阻塞(如溶解血栓)的功能或用途。目标专利明确要求声学能量源用于治疗(如超声溶解),而对比文件完全未涉及治疗目的,因此既未直接公开也未隐含公开该特征。
技术特征D:溶解元件,其被耦合到细长主体的远侧部分以与递送治疗能量不同的方式中断阻塞<br>《未公开》无相关引用对比文件未公开任何溶解元件(如球囊、加热元件、蒸汽元件等),其远侧部分仅设置有成像传感器,不涉及以不同方式中断阻塞的结构或功能。因此,该特征未被公开。
技术特征E:冷却元件,其包括用于耦合到声学能量源的热电冷却元件和用于将热消散到冷却流体的吸热设备<br>《未公开》无相关引用对比文件未提及任何冷却元件,特别是热电冷却元件或吸热设备。其超声换能器未设置主动冷却结构,因此该特征未被公开。
技术特征F:热电冷却元件包括被两条或更多条半导体电线分开的第一衬底和第二衬底<br>《未公开》无相关引用对比文件未公开任何热电冷却元件的具体结构,包括半导体电线、衬底等。因此,该特征未被公开。
技术特征G:以当半导体电线通过正极电源和负极电源被彼此连接时使得热从第一衬底被传递到第二衬底<br>《未公开》无相关引用对比文件未公开热电冷却元件的工作方式,因此该特征未被公开。
技术特征H:第二衬底与吸热设备相关联<br>《未公开》无相关引用对比文件未公开任何吸热设备与衬底的关联,因此该特征未被公开。
技术特征I:第一衬底和第二衬底被形成为声学能量源的背衬的部分<br>《未公开》对比文件第[2]段:“The backing layer 47 is bonded to the conductive layer 45b on the opposite surface of the core 44 from the matching layer 46. The backing layer serves to absorb acoustical energy generated off the nonimaging side of the transducer and also helps minimize energy reflections coming back to the transducer.” 但对比文件中的背衬层(backing layer)仅用于吸收声能,并非热电冷却元件的一部分,也未形成任何衬底或热电结构。对比文件虽公开了背衬层,但其功能、材料及连接方式均与目标专利中作为热电冷却元件的衬底完全不同。本领域技术人员无法从对比文件合理推断出背衬层可作为热电冷却元件的衬底,因此该特征未被公开。
技术特征J:其中,治疗能量为超声能量<br>《未公开》对比文件第[2]段:“The transducer sensor 42 creates a pressure wave pulse which travels through the elongate member into the arterial environment.” 以及“Ultrasonic energy includes acoustic waves.” 但对比文件中的超声能量用于成像而非治疗。对比文件使用的超声能量仅用于诊断成像,未公开用于治疗(如溶解血栓)的超声能量。目标专利要求治疗能量为超声,而对比文件未涉及治疗应用,因此该特征未被公开。
技术特征K:其中,内部构件被配置为在递送治疗能量的同时在细长主体内平移<br>《未公开》对比文件第[2]段:“the drive cable 28 and sensor assembly 24 are located in the flexible elongate member 26. The drive cable 28 can be rotated or moved longitudinally within the sheath.” 但内部构件的移动主要用于成像或调整位置,而非在递送治疗能量时进行。对比文件虽可能隐含内部构件可平移,但未结合治疗能量递送(治疗能量特征未被公开),且目标专利明确要求“在递送治疗能量的同时”平移,对比文件无治疗能量,因此该特征未被公开。
技术特征L:其中,内部构件被配置为在递送治疗能量的同时在细长主体内旋转<br>《未公开》对比文件第[2]段:“The motor 36 operates to rotate a proximal drive shaft located inside the proximal drive cable 32 which in turn rotates the sensor assembly 24 to which it is coupled via the distal drive cable 28.” 旋转用于成像扫描。内部构件旋转在对比文件中用于成像,而非治疗能量递送,且治疗能量特征未被公开,因此该特征未被公开。
技术特征M:细长主体限定递送管腔<br>《直接公开》对比文件第[2]段关于冲洗系统的描述:第一实施例“a flushing lumen 93 which may be a flexible tubular member having a diameter less than the diameter of the lumen 86 of the sheath 80.”;第二实施例“a sheath 94 having dual lumens, a main lumen 95 and an outer lumen 96. The outer lumen 96 provides a flushing channel to the distal end of the sheath 94 where it communicates with the distal end of the main lumen 94 through a opening 97 between the lumens 95 and 96.” 这些管腔均用于递送流体(冲洗液)。对比文件明确公开了细长主体(鞘管)内限定有用于递送流体的管腔(如冲洗管腔),该管腔从近端延伸到远端,与目标专利的递送管腔在结构上完全相同。虽然目标专利的递送管腔用于治疗物质,但对比文件中冲洗管腔的功能(递送流体)与结构等同,本领域技术人员可直接确认该特征。
技术特征N:递送管腔提供在被定位在细长主体的远侧部分处的开口与在细长主体的近侧端部的端口之间的流体路径<br>《直接公开》对比文件第[2]段关于第二冲洗实施例:“The outer lumen 96 provides a flushing channel to the distal end of the sheath 94 where it communicates with the distal end of the main lumen 94 through a opening 97 between the lumens 95 and 96. A flushing medium, typically water, is continuously fed under pressure through a proximal catheter manifold's flush port 98 through the flushing lumen 96 from the proximal end to the distal end, through the opening 97 into the main lumen 95, and back through the main lumen 95 from the distal end to the proximal end until the medium flows from the manifold's main port.”对比文件明确描述了递送管腔(冲洗管腔96)在远侧部分具有开口(开口97),在近侧端部具有端口(flush port 98),流体从近侧端口通过管腔流向远侧开口,形成流体路径。该特征与目标专利完全相同,直接公开。
技术特征O:其中,递送管腔与在细长主体的远侧部分处的多个开口流体连通<br>《未公开》无相关引用对比文件中的递送管腔(冲洗管腔)在远侧部分仅通过一个开口(如开口97)与其他管腔或外部连通,未公开多个开口。因此,该特征未被公开。
技术特征P:其中,溶解元件包括加热元件<br>《未公开》无相关引用对比文件未公开任何加热元件,因此该特征未被公开。
技术特征Q:其中,加热元件包括一个或多个电极<br>《未公开》无相关引用对比文件未公开电极,因此该特征未被公开。
技术特征R:其中,加热元件包括被设置在细长主体的第二管腔内的一条或多条光纤<br>《未公开》对比文件第[2]段涉及光学相干断层扫描(OCT)成像,但未用于加热。对比文件中的光纤用于成像,而非加热或溶解,且未公开作为加热元件的光纤。因此,该特征未被公开。
技术特征S:其中,溶解元件为球囊<br>《隐含公开》对比文件第[2]段关于液压驱动部分:“it would be possible to integrate a balloon onto the device. The hydraulic course would already be present, and if the balloon is ported to the same fluid used for driving the mirror, all that would need to be done to inflate the balloon would be to control the input pressure independent of the output flow rate.”对比文件明确提到了可以在设备上集成球囊,并给出了其与流体系统连接的基本思路。虽然未详细描述球囊作为溶解元件的具体用途,但本领域技术人员在阅读对比文件后,结合公知常识,可合理推断出球囊可用于血管内阻塞的处理(如压迫、扩张),且该球囊与目标专利中的球囊在结构上具有相似性。按照隐含公开的宽松标准,可认为对比文件部分公开了球囊这一元件,并可能将其用于溶解或阻塞处理中。因此,该特征被隐含公开。
技术特征T:还包括一个或多个功能流元件<br>《未公开》无相关引用对比文件未公开任何功能流元件(如压力传感器、流量传感器),因此该特征未被公开。
技术特征U:其被配置为获得身体管腔中的功能流数据<br>《未公开》无相关引用对比文件未公开功能流数据获取,因此该特征未被公开。
技术特征V:其中,溶解元件被定位在细长主体的远侧端部上<br>《未公开》无相关引用对比文件未公开溶解元件的位置,因此该特征未被公开。
技术特征W:溶解元件被配置为从远侧端部递送激光能量<br>《未公开》无相关引用对比文件未公开激光能量递送,因此该特征未被公开。
技术特征X:其中,溶解元件不是基于试剂的溶解剂<br>《未公开》无相关引用对比文件未公开任何溶解元件,因此无法判断其是否基于试剂,该特征未被公开。
