摘要： Methods for utilizing a device for blocking (e.g., embolizing) the side branches of an anatomical passageway under endoscopic guidance. The device comprises an elongate catheter body having a side branch blocking apparatus, such as an embolization catheter, disposed therein and further incorporating an endoscope (e.g., an angioscope). The incorporated endoscope is useable to a) visually locate side branches which emanate from the anatomical passageway and b) visually observe the operation of the side branch blocking apparatus. Disclosed are methods for performing in situ embolization of the side branches of a vein, under angioscopic visualization. The endoscopic component of the device may also be utilized to visually observe the use and/or effect of one or more separate device, such as valvulotome(s) used for cutting venous valves located within the lumen of a vein.

摘要： The invention is directed biopsy site markers and methods of marking a biopsy site, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging. The biopsy site markers of the invention have high ultrasound reflectivity, presenting a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The several disclosed embodiments of the biopsy site marker of the invention have a high contrast of acoustic impedance as placed in a tissue site, so as to efficiently reflect and scatter ultrasonic energy, and preferably include gas-filled internal pores. The markers may have a non-uniform surface contour to enhance the acoustic signature. The markers have a characteristic form which is recognizably artificial during medical imaging. The biopsy site marker may be accurately fixed to the biopsy site so as to resist migration from the biopsy cavity when a placement instrument is withdrawn, and when the marked tissue is subsequently moved or manipulated.
摘要翻译：本发明涉及活检部位标记和标记活组织检查部位的方法，使得活检腔的位置通过常规成像方法，特别是通过超声成像容易看到。本发明的活检部位标记物具有高的超声反射率，从小标记物呈现出实质的声学特征，以避免在随后的成像研究中掩盖诊断组织特征，并且可以容易地与生物特征区别开来。本发明的活检部位标记物的几个公开的实施方案具有放置在组织部位中的声阻抗的高对比度，以便有效地反射和散射超声能量，并且优选地包括气体填充的内部孔。标记可以具有不均匀的表面轮廓以增强声学特征。标记具有在医学成像期间可识别人造的特征形式。可以将活检部位标记物精确地固定到活检部位，以便当放置放置器械被取出时以及随后移动或操纵标记的组织时抵抗活组织腔的迁移。

摘要： A device and method of using the device to access a desired tissue site within a patient's body and separating a tissue specimen from the tissue site suitable for evaluation. The device includes a probe member having an arcuate tissue-cutting RF powered electrode secured to and distally spaced from the distal end of the probe and a small dimensioned distal extremity which when an inner lumen thereof is subjected to a vacuum, secured tissue for the specimen to the surface of the distal extremity. A circular tissue-cutting blade preferably secured to the distal end of a supporting tube is configured to rotate and move longitudinally along the shaft of the probe member effective to sever a tissue specimen from tissue secured to the surface of the distal extremity of the probe member. The supporting tube covers the separated specimen, and may be disposed within an accessing cannula.

摘要： The invention is directed to a system and method for separating and collecting one or more tissue specimens from a target site within a patient and flushing the specimen to remove blood, debris and the like before the specimen is removed from the biopsy device. The flow of flushing fluid to the tissue collector is preferably controlled to coincide with delivery of one or more specimens to the collecting tray or basket of the device or after the receipt of the specimen within the tissue collector to ensure that the fluid is applied to a fresh specimen. The tissue tray or basket within the tissue collector has an open or foraminous portion to facilitate removal of fluid, such as the applied fluid and blood, and other debris from the tissue specimens on the tray. Vacuum is provided within the tissue collector, preferably under the tray to remove fluid and debris from the collector interior.
