摘要： Endoscopic biopsy forceps jaws having an outer edge which may be generally U-shaped, circular, or oblate circular are disclosed with teeth which extend completely around the outer edge. The teeth may take any of several arrangements. In a first arrangement, the teeth and valleys are formed with two substantially rectangular surfaces which meet at substantially horizontal vertex and nadir lines. In a second arrangement, each tooth has a vertex or peak located upward and inward from the outer edge, and is defined by a substantially triangular inner surface, a substantially quadrilateral base, and a surface which extends outward and downward from the vertex of the triangular surface to the outer edge of the jaw. Valleys between the teeth have two inclined surfaces which intersect along a line which extends inward and downward from the outer edge of the jaw. In a third arrangement, the peak of each tooth is defined by the vertex of a pyramid having four faces and valleys between these teeth have three substantially flat surfaces which intersect at a vertex which lies downward and inward from the outer edge of the jaw. Alternate embodiments of all arrangements include providing a lip around the outer portion of the outer edge so that the teeth and valleys are spaced farther in from the outer surface of the jaw cup.

摘要： A tapered helical implantation device for peripheral arteries and other body lumina of locally varying diameter, including struts connected by loops and shaped in a helical winding. The helical winding defines turns and, when expanded, has a first end with a first expanded circumference and a second end with a second expanded circumference greater than the first expanded circumference to form a stent tapering outward from the first end towards the second end. Bridges connect adjacent ones of the turns. The struts, the loops, and the bridges define a series of pores aligned along the helix, the pores having a substantially uniform pore size. The pores has a substantially similar area. The pore size limits a size of a particle that can pass therethrough. In particular, the pore size limits a size of a spherical particle that can pass therethrough.

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 filter basket device includes two shaft wires, a filter basket adapted to capture emboli and thrombi, and an actuation handle. The shaft wires are loosely twisted together so that they remain adjacent to each other, and yet are able to slide relative to each other with little friction and without plastic deformation. One shaft wire is connected to the distal end of the filter basket, and the other shaft wire is connected to the proximal end of the filter basket. The actuation handle moves the shaft wires relative to each other to control opening and closing of the basket. In one embodiment, a guidewire-accepting fitting is attached to a distal portion of the device and permits advancement of the device over a guidewire until a desired location along the guidewire is reached. In another embodiment, the basket is provided with a tip resembling a guidewire.

摘要： An electro-surgical device for performing tissue resection and cauterization includes an elongated body, a pair of arms extending from a distal end of the elongated body, and an electrode in communication with the pair of arms. The elongated body is adapted to be coupled to a source of energy at a proximal end. The electrode has a first region coated with an insulative coating and a second region for focusing energy emission. The coating can be a diamond-like carbon coating or other coating exhibiting resistance to cracking at high temperatures and high voltages. The coating can be deposited on a base section of a loop electrode while the end sections remain free of the coating. Alternatively, the coating can be unevenly deposited on the electrode. In other embodiments, the electrode can comprise a rollerball and the insulative coating can be deposited on selected or random portions of the rollerball. The insulative coating prevents energy loss to fluid and tissue during the operation, thus allowing resection and cauterization to be efficiently performed.

摘要： A process for providing an endoscopic scissors blade with the necessary roughness to receive a ceramic coating, without first requiring that the blade surfaces be roughened by gritblasting, includes obtaining an investment mold with an interior textured surface. The investment mold is textured by first texturing an injection mold cavity by etching, gritblasting, or electric-discharge machining the inside surface of the injection mold cavity to produce a desired roughness. A blade pattern (wax) is then formed in the injection mold with a resulting textured surface, and using the textured blade pattern, the investment mold with the textured interior cavity is generated. When metal is injected into the investment mold using a lost wax process, the resulting cast blades will have the necessary roughness for permitting a ceramic to be bonded thereto without the need for any additional roughening. Thus, the so-formed blades are coated with a ceramic material. Such scissors blades are used in an endoscopic surgical scissors instrument and are especially useful as the scissor blades of a bipolar cautery endoscopic scissors instrument.

摘要： An endoscopic suctioning instrument with variable suction is disclosed. The instrument has a hollow cannula having a proximal end and a distal end, and sliding sleeve having a proximal end and a distal end and a longitudinal axis, with the sliding sleeve being coaxial to and closely surrounding and slidingly engaging the hollow cannula. The sliding sleeve has a plurality of lateral holes at its distal end with the lateral holes being spaced along the longitudinal axis. A valve is provided for selectively coupling a suction source to the proximal end of the cannula, and a sleeve actuation mechanism is provided for sliding the sliding sleeve from a first position where the distal end of the sliding sleeve extends beyond the distal end of the cannula such that a first number of the lateral holes are unblocked by said cannula, to a second position where the distal end of the sliding sleeve extends beyond said distal end of the cannula such that fewer lateral holes are unblocked by said cannula, to a third position where the cannula blocks all of said lateral holes of the sliding sleeve. Various embodiments are described with different mechanisms for causing the sleeve to slide, including mechanisms linking the valve to the sleeve.
