摘要： A method and apparatus for analyzing micturition disturbances are provided. The apparatus comprises a gas cystometry system for monitoring bladder detrusor reflexes and an electromyographic monitoring system which, in the preferred form of this invention, are combined within a unitary enclosure. The cystometry system further compromises a catheter for injecting fluid interiorly of the bladder and associated electronic circuitry for deriving interior bladder pressure. The electromyographic system comprises one or more electrodes for sensing sphincter electrical activity and electronic circuitry interconnected with the electrodes for amplifying sphincter electrical outputs. A dual trace strip chart recorder interconnected with the cystometry apparatus and the electromyography apparatus provides simultaneous display of bladder detrusor reflexes and related sphincter electrical activity for correlated analysis by the attendant physician. In the preferred embodiment of this invention the electromyographic electrodes are operably mounted at the bladder-engaging end of a cystometric catheter.A method disclosed herein for diagnosing micturition dysfunction comprises the steps of generating a cystometrogram, generating a sphincter electromyogram, and simultaneously displaying the cystometrogram and the electromyogram to thereby correlate micturition neurological responses.

摘要： A method and apparatus for diagnostic evaluation of the urinary tract. The method comprises the steps of generating a urethral pressure profile and simultaneously monitoring and recording electrical signals derived from the urinary tract thereby generating an electrical or electromyographic profile. As fluid is inputted into the urethra the catheter is mechanically withdrawn therefrom at a constant velocity. Fluid pressure within the urethra is derived and recorded thereby providing a urethral pressure profile. Simultaneously, urethral electrical signals derived from one or more electrodes mounted on the catheter are amplified and graphically displayed, thereby plotting urethral electrical activity and urethral fluid pressure at given points along the urethra. The apparatus comprises an interface unit for withdrawing the catheter and for enabling measurement of the various diagnostic parameters.

摘要： The urethral catheter puller described in this application provides a convenient apparatus for performing urological diagnostic procedures such as urethral pressure profilometry and urethral electromyographic profilometry. In practice, a urethral catheter is mounted on catheter supports attached to the boom of the puller. The boom is equipped with positioning apparatus so that the catheter supports may be positioned in close proximity to the patient. The puller allows the catheter to be pulled in a horizontal or vertical direction, thus allowing the patient to stand or lie in a bed during the diagnostic procedure. The catheter supports are equipped with suitable structures to control the motion of the catheter as it is withdrawn from the urethra of the patient. A variable speed drive is provided to control the rate at which the catheter is withdrawn.

摘要： A method and apparatus for packaging a fluid containing prosthesis adapted to be implanted in a sterile condition involves filling a closable, permeable fluid containing housing within the prosthetic device with a fluid. The prosthetic device is then enclosed within a substantially fluid impenetrable enclosure that is filled with a fluid with activities which substantially match the activities of the fluid within the prosthetic device. Thus, even where the prosthetic device contains a physiological solution, by incorporating a solution of equal solute concentration within the enclosure that surrounds the prosthetic device, the tendency for osmosis to occur across the barrier defined by the walls of the prosthetic device can be adequately controlled. The enclosure may then be enclosed within an outer bag which may be handled by a non-sterile nurse, preparatory to implantation by a surgeon. In this way, it is possible to ship a prosthetic device in a fluid filled state despite the tendency for migration through the walls of the device by establishing mass transfer equilibrium within the package.
摘要翻译：用于包装适于被植入无菌状态的含有假体的流体的方法和装置包括用流体在可修复的装置内填充容纳可渗透的流体的壳体。然后将假体装置封闭在基本上流体不透气的外壳内，该外壳充满流体，其活动基本上与假体装置内的流体的活动相匹配。因此，即使在假体装置含有生理溶液的情况下，通过在围绕假体装置的外壳内并入等溶质浓度的溶液，可以充分控制由假体装置的壁限定的阻挡层渗透的趋势。然后可以将外壳封闭在外袋内，该外袋可以由非无菌护理员处理，准备由外科医生植入。以这种方式，通过在包装内建立传质平衡，可以将假体装置运送在流体填充状态，尽管倾向于通过装置的壁迁移。

摘要： A design and method of manufacture is disclosed for an insulated electrode used during surgical procedures. The electrode includes a durable electrical insulation element that can withstand the range of temperatures generated during an electrosurgical procedure. Such insulation characteristics include resistance to meltback and manufacturability to ensure the device is biocompatible and non-toxic so as to prevent adverse reactions in both patients and users of the device. The insulated electrode further includes properties that reduce the incidence of scope damage caused by the intensity of heat generated during the cutting and coagulation cycles.
