摘要： A multifilar flexible rotary shaft includes a plurality of individual filaments which are not wound around each other or around a central core, a loose ensemble of filaments. The input ends of each filament are coupled to each other and the output ends of each filament are coupled to each other. Preferably all of the filaments are identical. A loose ensemble of N filaments can transmit N times the torque of a single filament, and will have N times the torsional stiffness of a single filament, while retaining the minimum radius of operation of a single filament. Since a loose ensemble of filaments does not have any appreciable contact forces among the filaments (because they are not forcibly twisted together), there is no appreciable internal friction or hysteresis. In order to appreciably eliminate all the hysteresis in such an ensemble of filaments, the filaments should be no more than loosely twisted together, if at all. The only reason for loosely twisting the wires together is to allow the ensemble to be easily handled and to insure that the individual wire filaments follow the same general curved path from one end to the other. Several practical applications of the invention are also disclosed.
摘要翻译：多针柔性旋转轴包括多个单独的细丝，它们彼此不缠绕或围绕中心芯，松散的细丝组合。每个灯丝的输入端彼此耦合，并且每个灯丝的输出端彼此耦合。优选地，所有的长丝是相同的。 N细丝的松散组合可以传播N倍的单丝的扭矩，并且将具有单丝的扭转刚度的N倍，同时保持单丝的最小操作半径。由于长丝的松散组合在细丝之间没有任何明显的接触力（因为它们不被强制扭曲在一起），所以没有明显的内部摩擦或滞后。为了明显地消除这种灯丝组合中的所有滞后现象，如果有的话，灯丝不应该松散地扭曲在一起。将电线松散地缠绕在一起的唯一原因是允许集合容易地处理并且确保单个线丝沿着从一端到另一端的相同的一般弯曲路径。还公开了本发明的几个实际应用。

摘要： A snap-fit collar for coupling the end of a flexible coil to a part of an endoscopic instrument is a substantially cylindrical member having a first end portion with a stop flange, a resilient tapered locking flange spaced apart from the stop flange defining a waist or groove between the stop flange and the locking flange, and second end portion having a pair of cantilevered substantially semi-cylindrical legs. The first end portion is preferably frustroconical and flares diametrically outward to form the stop flange which has a first diameter. The waist or groove has a second diameter which is smaller than the first diameter. The tapered locking flange is also preferably frustroconical and tapers diametrically inward from a third diameter which is larger than the second diameter. Each of the legs is inclined diametrically outward and includes a plurality of coil engaging ribs on its inner surface. The outer surface of each leg is preferably provided with a longitudinal key and the free end of each leg is preferably tapered radially inward. The collar has a throughbore which extends through the first end portion to the space between the legs. An endoscopic instrument actuator and a clevis for use with the snap-fit collar each include a throughbore having a step and a pair of diametrically opposed keyways which extend into at least a portion of the throughbore wall.

摘要： A biological forceps device is disclosed for the taking of tissue samples from a body. The biopsy forceps device comprises a flexible main coil having a distal end which is stiffer than the majority of the coil, a pair of opposed jaws hingedly disposed on the distal end of the coil, and an actuator having a distal end coupled to the hingedly disposed jaws for effecting articulation of the jaws. Preferably, shrink wrap tubing is placed on the distal end of the coil and acts as the stiffening agent thereof. A stiffer distal end permits the practitioner to press the jaws deeper into the tissue and reduces the jump experienced at the distal end when the coils go from a state of tension (jaws open) to a state of compression (jaws closed), so that a better sample can be obtained.

摘要： A surgical clip includes a U-shaped configuration with first and second arms, and a bridge portion therebetween. The first arm is provided with a tip preferably having a catch, and the second arm extends into a deformable retainer having a tissue-piercing end and preferably also a hook. During application, tissue is clamped, and the clip is forced over the clamped tissue and the retainer of the second arm is bent and may be pierced through the tissue. The retainer is toward and around or adjacent the tip of the first arm preferably until the hook is engaged about the catch to secure the clip to the tissue and prevent the clip and tissue from separating. The clip is provided with structure that facilitates the stacking of a plurality of clips in a clip chamber of a clip applier.

摘要： A helical stent having a central helically wound portion, and cylindrical ends is provided. A transition zone having struts of different lengths is provided between the helical portion and each cylindrical portion. A junction defining a strut trident is provided between the transition zone and the helical portion. This construction provides a highly flexible stent, permits connecting bridges that are in the same basic orientation, and enables the hoops of the helical, cylindrical, and transitions zones to remain “in phase” such that the stent can easily expand and collapse. According to another aspect of the invention, the kerf between adjacent struts does not go all the way to the end of those struts. The longer struts can have substantially the same flexibility and expansion force as the shorter struts of the transition by making all the kerfs approximately the same length.

摘要： Radioactive therapeutic seeds include a carrier structure bearing a radioactive isotope and a radiopaque marker. According to several embodiments, the seeds include a central plug provided with an axial marker and a relatively transverse bore extending through the marker. A second marker may be positioned in the bore, thereby distinguishing a seed provided with the second marker relative to a seed not provided with the second marker. According to another embodiment, the isotope is deposited on the outer surface of a hollow radiolucent tube. A biologically-compatible, radiolucent, surface-sealing layer seals the external surface of the tube. A radiopaque marker wire of selected length is positioned in the hollow of the tube. Seeds may be distinguished from one another by providing seeds with marker wires of different lengths. According to other embodiments, the seed includes a cylindrical outer member, and an inner member provided within the outer member and having two large diameter portions and a relatively smaller diameter portion therebetween. A marker is disposed within the inner member, and a radioactive isotope is carried on the inner member. The marker may be drilled to a smaller size. Each embodiment permits at least two groups of seeds to be distinguished from one another by the use of differing marker configurations.
