摘要： The present invention relates to methodology of an apparatus for accurately positioning devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. The sphincterotome with a steerable or adjustable distal segment of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy. According to one embodiment of the present invention, a threaded portion of a cable assembly cooperates with a torque transmission element and a cog to enable the operator to rotate a cutting wire into a desired position relative to the catheter. Alternate embodiments allow the operator to fix the depth of a needle knife while allowing, if desired, accurate rotational positioning of the associated catheter. Threaded stabilizing elements, pivot elements and a steering wire may be used together or individually to accomplish these features. Presently available products that may be modified according to the present invention include, but are not limited to, Boston Scientific Sphincterotomes and Needle Knives.
摘要翻译：本发明涉及准确定位用于进行内窥镜插管，乳头切开术和括约肌切开术的装置的方法。具有本发明的可转向或可调节的远端段的括约肌切片机允许医师独立于内窥镜来控制装置的远侧末端的位置，并且针对装置和解剖结构中的不一致性进行调整。根据本发明的一个实施例，电缆组件的螺纹部分与转矩传递元件和齿轮协作，以使操作者能够将切割线相对于导管旋转到期望的位置。替代实施例允许操作者固定针刀的深度，同时允许相关导管的精确的旋转定位。螺纹稳定元件，枢转元件和操纵线可以一起使用或单独使用以实现这些特征。目前可以根据本发明进行修改的产品包括但不限于波士顿科学耳鼻喉科和针刀。

摘要： A flexible composite tube (1) for medical applications is described. The tube (1) has the ability to transmit a torque and to resist compression, tension, and kinking. The tube (1) is also very flexible in bending, and has a small wall thickness. Different layers are used to obtain the desired properties. Torsional stiffness is obtained by embedding a braid (10) in an elastomeric material (20). Resistance to kinks and to compression and tension is obtained by placing coils (30) radially inward or outward of the braid (10). Smooth plastic layers (80, 90) are used to seal the assembly, and facilitate sliding in a body cavity.

摘要： A steerable endoscopic sheath has a proximal end, a distal end and a working channel lumen disposed therein. A plurality of solid state light emitting devices such as light emitting diodes are positioned near the distal end of the sheath and are selectively energized to illuminate internal body tissues. An imaging device such as a photo diode or CCD array creates an image from light reflected from the tissue. The distal tip of the endoscopic sheath is selectively moveable with a deflection device that is insertable into the sheath. The deflection device includes a tip deflection mechanism that allows a user to move the tip of the deflection device. With the deflection device inserted in the sheath, movement of the distal tip causes a corresponding movement in the distal tip of the sheath. The distal tip of the sheath has a shape retaining mechanism that allows it to retain the shape imparted by the deflection device once the deflection device is removed from the sheath.

摘要： A device for treating a lesion comprises a sheath extending from a proximal end which, in an operative position, is located outside the body, to a distal end which, in the operative position is located within the body. A needle extending through the sheath has a tissue piercing distal tip and a central lumen extending through the needle from a proximal port to a distal opening formed in the distal tip and a needle actuator is provided for moving the needle between a retracted position in which the distal tip is received within the sheath to an injection position in which the distal tip extends distally beyond a distal end of the sheath. A snare extends within the lumen to a loop formed in a distal end of the snare and a snare actuator is provided for moving the snare between a covered position in which the loop is received within the lumen and an extended position in which the loop extends distally from the lumen beyond the distal tip.

摘要： A ligating band dispenser comprises a substantially cylindrical first support surface capable of holding a plurality of first ligating bands. The first support surface has a first channel extending substantially axially therethrough and a plurality of first slots extending away from a distal end thereof through at least a portion of the first support surface. A plurality of increased diameter abutting portions define a plurality of segments of a pull line extending through the slots with each of the abutting portions being retained within the channel by contact with a corresponding one of the slots. Each of the segments loops around a corresponding one of the ligating bands to releasably couple the pull line to the ligating bands.
