摘要： A permanent acute occlusion implantable device and method are described for immediate occlusion of a body lumen, such as blood vessels and the fallopian tubes of the human female, wherein an balloon expandable lumen occlusion device is placed within the lumen to be occluded. After inflating the balloon, the balloon is withdrawn leaving the expanded occlusion device in the lumen. The device is encased in an occluding impervious sheath and therefore completely occludes the lumen once the device is delivered and anchored into the inner wall of the body lumen.

摘要： A support device suitable for urethral support is adjustable for length post operatively. An elongated body has at least one bellows and a line going through a passage in the elongated body. The elongated body is supported in the patient and the line is adjustable by balloon inflation or rotation of a drum. The amount of support can be changed postoperatively using an instrument inserted through the skin with a local anesthetic or even from outside the skin with no surgical intervention. The bellows changes length when adjustments are made.

摘要： The invention discloses a stent which has a locking feature to prevent recoil. The stent is composed of a plurality of rings which are joined by crossties of various construction. The locking feature of each ring can be in alignment or staggered. The crossties may be straight or angled or they may have curvature to them to further promote longitudinal flexibility. The locking mechanism includes features which minimize sharp ends exposed to the vascular wall.

摘要： A stent delivery apparatus is disclosed comprising a movable inner tube and a fixed outer tube having corrugations or undulations at its distal end. The undulations or corrugations are stretched by movement of the inner tube, whereupon the stent is placed over the relatively flattened undulations or corrugations. A solid structure or an open structure such as a coil can be used for this purpose. One large proximal undulation is provided for preventing the stent from sliding from the predetermined location during the setting. Upon relative movement between the inner and outer tubes, which can be a single longitudinal or twisting movement or a combination of such movements, the undulations under the stent are outwardly relaxed, forcing the stent to expand toward the vascular wall. The relative movement is then reversed to retract the undulations and the delivery device withdrawn. In an alternative embodiment, the undulations are perforated to allow perfusion under and through the stent from a point external to the patient's body to a point distal of the placement of the stent during the procedure of stent expansion.
摘要翻译：公开了一种支架输送装置，其包括在其远端具有波纹或起伏的可移动内管和固定外管。起伏或波纹通过内管的移动而被拉伸，于是支架置于相对扁平的起伏或波纹之上。为了这个目的，可以使用固体结构或诸如线圈的开放结构。提供一个大的近端起伏，用于防止支架在设定期间从预定位置滑动。在内管和外管之间的相对运动（其可以是单个纵向或扭转运动或这种运动的组合）中，支架下方的波纹向外松弛，迫使支架朝向血管壁扩张。然后将相对运动反向以收回起伏并将递送装置撤回。在替代实施例中，波纹穿孔以允许在支架膨胀过程期间从支架外部的位置到支架远侧的点之间的灌注下和通过支架。

摘要： A permanent acute occlusion implantable device for sterilization of human female and method are described for immediate occlusion of the fallopian tubes of the human female, wherein an structure having an a shape to the normal anatomy of the ostium of the fallopian tube device consisting of a sealing segment is placed to seal the ostium of the fallopian tube. The sealing segment of the device is encased in an elastomeric material to provide the sealing action once the device is delivered into the ostium of the fallopian tubes. The occlusion device is held in place due to the spring action of the intermediate connecting segment which in turn is connected to an expanding anchoring segment. The occlusion device is delivered to the final location via a delivery sheath which is threaded through a hysteroscope.

摘要： An occlusion device has spaced struts connected by end members and is covered with a sheath. An actuator runs through the frame defined by the struts and end members. The struts are delivered in tension and allowed to relax to flex outwardly for fixation. The struts can also be placed in a relaxed condition and then flexed with relative movement of the end members when coming closer together. The set position of the struts is locked. The actuator can be at least in part removed after the struts flex. An anchor can be placed proximally to the frame and it contains spaced elongated members connected into a tubular shape with circumferential bands that have bends for flexibility to collapse for insertion and expand when placed in the lumen.

摘要： The present invention uses several innovative means in order to effectively puncture the intimal wall of blood vessels reliably and controllably. The total penetration of the needle is controlled by the height of the needle projecting from its base and the degree of penetration is controlled by the use of “cam” or similar means or mechanisms that moves the base containing the needles.

摘要： A flexible stent is disclosed that can be constructed in a variety of ways. It can be made from a continuous wire formed into discrete rings of undulating bends where the end rings are closed up on themselves, and the continuous wire which forms the rings between the end rings defines longitudinal gaps in each of the internal rings, which gaps are in turn straddled by crossties which, in the preferred embodiment, extend in a perpendicular plane to the longitudinal axis of the stent, while being disposed in alignment with the cylindrical surface defined by the stent. The crossties act to keep the opening in the inner rings constrained during expansion of the stent. The presence of the longitudinal openings in the internal rings adds to the flexibility of the stent to ease delivery to the desired location. Alternatively, the flexible stent can be etched from a tube. In this preferred embodiment, alternating rings of an undulating wire-type element, etched from a tube, are presented. The rings alternate between those that are fully closed upon themselves, interspersed adjacent those that have a longitudinal opening, coupled by crossties which extend symmetrically from opposite sides and opposite ends of the longitudinal opening in the open rings to attach to the ring above and ring below. The disposition of the crossties helps the stent expand by providing resistance to opening of the longitudinal gap during expansion. The presence of the longitudinal gap adds to the flexibility of the stent for proper delivery to the desired location.
摘要翻译：公开了可以以各种方式构建的柔性支架。它可以由连续的线形成，其形成为起伏弯曲的离散环，其中端环自身闭合，并且在端环之间形成环的连续线限定每个内环中的纵向间隙，该间隙然后又被跨栏铺设，在优选实施例中，它们在与支架限定的圆柱形表面对齐的同时在垂直于支架纵向轴线的平面上延伸。支架用于在支架膨胀期间保持内环中的开口受到限制。内环中的纵向开口的存在增加了支架的柔性，以便于输送到期望的位置。或者，可以从管中蚀刻柔性支架。在该优选实施例中，呈现了从管蚀刻的起伏线型元件的交替环。这些环在其自身完全闭合的环之间交替，与相邻的那些具有纵向开口的那些相交，所述纵向开口与通过开放环中的纵向开口的相对侧和相对端对称延伸的交叉连接，以连接到上面的环上并环绕。在扩张期间，通过提供对纵向间隙的打开的阻力，支架的布置有助于支架的扩张。纵向间隙的存在增加了支架的柔性，以适当地输送到期望的位置。

摘要： An antiglare tip for the sheath of an endoscope to prevent glare in an image viewer is disclosed. The antiglare tip includes an interfitting region with the endoscope to ensure that all light entering the image viewer is reflected from objects external to the endoscope. An opaque projection extends from the endoscope insertion tube between the light source and the image viewer. Opaque recesses in the tip are positioned to mate with the opaque projections extending from the endoscope end. Having mating projections and recesses aligned ensures that no light may pass directly from the light source to the image viewer via the tip. Glare resulting from internal reflections in the tip, or from an inside surface of the tip, is prevented.
摘要翻译：公开了一种用于内窥镜护套的防眩光尖端以防止图像观察者中的眩光。防眩光尖端包括与内窥镜的配合区域，以确保进入图像观看者的所有光从内窥镜外部的物体反射。不透明突起从光源和图像观察者之间的内窥镜插入管延伸。尖端中的不透明凹槽定位成与从内窥镜端延伸的不透明凸起配合。使匹配的突起和凹槽对准确保了光线不能通过尖端直接从光源传递到图像观察者。防止了尖端内部反射或从尖端的内表面引起的眩光。
