摘要： A catheter includes a flexible elongated catheter body (10), a retractable needle or probe (36), and an electrode (26) mounted on the distal portion of the catheter body (10). The needle (36) provides a fluid passage (39) for introducing fluid (e.g., sclerotic agents for enhancing electrocoagulation of the tissue, heat responsive drugs for improving bonding to tissue surfaces, or vasoconstrictor drugs) into tissue. The electrode (26) can provide bipolar electrocoagulation by means of two separate constituent electrodes, or alternatively, the electrode (26) can be employed in combination with either the needle or probe (36) to establish the bipolar elecrocoagulation path through tissue into which the needle or probe (36) extends. The electrode (26), in combination with the needle or probe (36), may also be used to provide a mapping function inside cardiac chambers.

摘要： Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include a medical guide wire (2) with stiff portion (14), transition portion (16) and flexible portion (18), a catheter (140) and a sphincteral (170).

摘要： A miniaturized spectrometer is adapted for placement within a body near tissue to be characterized. The spectrometer includes a light source (3) and a plurality of light detectors (61). The light source generates light to illuminate the tissue. The detectors detect optical signals from the illuminated tissue and convert these optical signals to electrical signals. The miniaturized spectrometer can be disposed at the distal end of an interventional device (4). Optical conduits, such as fiber optic cables or strands, extending the length of the interventional device are not required when the miniature spectrometer is employed.

摘要： A dilation balloon for a catheter (2) with improved folding characteristics for insertion into a body conduit. The balloon surface is generally textured, having a reduced texture longitudinal strip (14) causing preferential controlled folding along the strip. The preferential folding creates curved wings which fold together upon further deflation. The curved, folded wings result in a decreased profile having wing edges oriented so as to decrease contact with conduit walls. A preferred embodiment has raised radial ridges (12) extending around a portion of the circumference of the balloon and a smooth longitudinal surface radially therebetween.
摘要翻译：用于导管（2）的扩张气囊，其具有用于插入体导管中的改进的折叠特性。气球表面通常是纹理的，具有减小的纹理纵向条带（14），导致沿条带的优先控制折叠。优惠折叠产生弯曲的翅膀，在进一步的放气时折叠在一起。弯曲的折叠的翼导致减少的轮廓，其翼缘定向成减小与导管壁的接触。一个优选实施例具有围绕球囊的圆周的一部分延伸的径向脊（12），并且其间径向地具有平滑的纵向表面。

摘要： An expansible balloon catheter (10) has at least a first exterior surface (27) with a given coefficent of friction and a second exterior surface (32) with a greater coefficient of friction. In a compact form only the first exterior surface is exposed to produce one coefficient of friction during transfer of the collapsed or uninflated balloon to and across a lesion. When inflated, the second surface dominates the first surface and produces a second coefficient of friction.

摘要： This invention is a ureteral stent (100) for assisting movement of urine along a patient's ureter and into the patient's bladder. The stent (100) includes an elongated tubular segment (130) extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen (260) connects at least one opening (127) at the first end region to at least one opening in the bladder end region. At least one flexible tail (110) is attached to the bladder end region of the tubular segment (130) at a point outside the bladder so as to receive urine from the opening in the bladder end region of the tubular segment (130) and to transport urine from there across the ureter/bladder junction and into the bladder. The tail (110) includes an elongated external urine transport surface sized and configured to transport urine along the ureter. The urine transporting surface is sized and configured to extend along at least part of the ureter, across the ureter/bladder junction, and from there into the bladder.

摘要： A catheter for diagnosing body interiors utilizing the transmission and receiving of ultrasonic waves. The catheter has a patient insertable distal end (16) and a proximal end (20) and comprises an elongated catheter sheath including an ultrasonically transmissible section (13) adjacent the distal end. It further includes a reservoir disposed within the sheath and adjacent the distal end. A frangible membrane (15) is disposed within the sheath and seals the reservoir from the interior of the sheath. A liquid (12) is disposed within the reservoir and contained therein by the frangible membrane. A transducer (11) for generating and receiving the ultrasonic waves is used to break the membrane when it is slipped into the sheath so the transducer will be bathed in the liquid and provide sonic transmissions within the catheter.

摘要： An apparatus (10) and a method for managing polyps by which an elongated tubular member (11) generally positionable within a working channel of an endoscopic device. The tubular member (11) carries a selectively extendable severing device (13) and capturing device (14) at its distal end (12). Slide member (17) at the proximal end (16) of the tubular member (11) enables a physician to extend and retract the severing and capturing devices (13, 14). The physician retracts the capturing device (14) to grasp the portion of the polyp to be severed and retracts the severing device (13) to sever the polyp. The capturing device (14) retains the severed portion of the polyp for removal with the tubular member (11). In one of the embodiments the capturing device (14) includes an injection needle (71A).

摘要： A guidewire (10) adapted to be inserted into a vascular vessel or into a catheter that is to be inserted into a vascular vessel or the like. The guidewire comprises a coil of flexible radiotransparent wire having a proximal section (11) and a distal section (12). The proximal section (11) is formed of a coil of wire having abutting turns and distal section is formed by the same coil of wire with the turns of wire being spaced from each other. A layer of radiopaque material of predetermined length is disposed in a predetermined location on the distal section, the interior of the layer being interstitially disposed within the outer surface of the coil. A hemispherical tip (15) is disposed at the distal end of the distal section (12). A small braze (14) is made at the juncture between the proximal section and the distal section to prevent spreading of the coils from the abutting relationship in the proximal end of said guidewire.
