摘要： An intubation device comprises an imaging conduit including an illumination conduit for delivering illumination to a distal end of the device and an image-receiving conduit for communicating images from the distal end of the device to the proximal end of the device. The device also comprises a flushing conduit for delivery of fluids and/or gases to the distal end of the device. The image conduit and the flushing conduit are attached at the distal end of the device. The distal end of the device can be manipulated by advancing the imaging conduit in an axial direction while maintaining the flushing conduit fixed in place. Furthermore, a length adjustment member is provided for adjusting the extent to which the distal end of the device extends beyond a distal end of an endotracheal tube which is inserted over the imaging and flushing conduits. The illuminating conduit and the image-receiving conduit terminate in separate ports at the distal end of the device. Furthermore, a substantial portion of the device is disposable, so that time consuming sterilization is not necessary.

摘要： A surgical access device and method are provided for endoscopic surgeries comprising biopsies or other surgical cutting procedures. The device generally comprises a substantially rigid first channel associated with a first port and a second channel associated with a second port of a proximal housing. The first or main channel extends to a curved distal end of the device, and the second channel is connected to a guide channel extending tangential to the main channel. The guide channel comprises substantially noncompliant material and has a pre-insertion position such that a cross-section of an inserted portion of the device is substantially the same as a cross-section of the main channel. A preferred method of the present invention includes the use of an open-loop device formed at a distal tip of an introducer and an aspiration tube during the location, excision and removal of one or more tissue specimens.

摘要： An endoscope including an elongated endoscope body sized and adapted for insertion into a passage, such as a passage of the body of a patient. Optical components are carried by the endoscope body to enable viewing of the passage distally of the distal end of the endoscope body within a field of view of the endoscope. An elongated, resilient member is mounted on and carried by the endoscope body such that the endoscope body and the resilient member are a unitary assembly which can be inserted as a unit into the passage. The resilient member extends beyond the distal end of the endoscope body and is capable of contacting material within or forming the passage and relatively displacing the distal end of the endoscope body and such material within the field of view of the endoscope to enhance viewing of the passage with the endoscope.

摘要： A method and apparatus extract a signal component of a measured signal using one of two methods. If the signal component in the measured signal is a periodic signal with a certain well-defined peak-to-peak intensity value, upper and lower envelopes of the measured signal are determined and analyzed to extract said signal component of the measured signal. This signal component can further be used to calculate a desired parameter of the sample. The DC component of the signal is determined as the median value of the upper envelope, and the AC component is determined as the median value of the difference between the upper and lower envelopes. If the signal component of the measured signal is a periodic signal characterized by a specific asymmetric shape, a specific adaptive filtering is applied to the measured signal, resulting in the enhancement of the signal component relative to a noise component. This adaptive filtering is based on a derivative of the Gaussian Kernel having specific parameters matching the characteristics of the signal component.

摘要： This invention provides a linear stapling instrument for use in surgical procedures including, inter alia, a staple housing. The housing includes a plurality of staple openings and a plurality of staples disposed in the staple openings. The housing further includes a plurality of staple drivers. The staple drivers have an upper surface bearing on a staple and a lower camming surface. The staple drivers are slidably mounted in the housing for movement from an initial lower position to an upper position. They also are arranged such that their lower camming surfaces are disposed in one or more spaced rows. The housing also includes a sled slidably mounted in the housing for movement from an unfired position to a fired position. The sled has at least one camming surface. The camming surface is disposed on the sled such that movement of the sled from its unfired to its fired position causes the camming surface to contact in sequence the lower camming surface of the staple drivers in at least one the row. The staple drivers, thus, are cammed from their lower to their upper positions, and they in turn eject the staples from the staple openings.

摘要： A trocar for use in surgical procedures including a cannula for maintaining a sealed working channel in a body wall and an obturator which creates the working channel through the body wall while protecting patients and medical personnel from harm is disclosed. A cannula converter which can be employed with the trocar to enable a surgeon to use surgical instruments having a smaller outer diameter than the inner diameter of the cannula without deflating a body cavity is further disclosed. A site stabilizer which can be used with the trocar to prevent the cannula from being inadvertently withdrawn from the body cavity during a surgical procedure is also disclosed.

摘要： Apparatus and methods are provided for monitoring cardiac output using bioelectrical impedance techniques in which first and second electrodes are placed in the trachea and/or bronchus in the vicinity of the ascending aorta, while a sense current is injected into the thorax via first and second source electrodes, so that the resulting bioelectrical impedance measurements reflect voltage changes induced primarily by blood flow dynamics, rather than respiratory or noncardiac related physiological effects. Apparatus and methods are also provided so that the measured cardiac output may be used to control administration of intravenous fluids to a patient or to optimize heart rate for those patients having pacemakers.

摘要： A surgical clip applier for application of surgical clips to body tissue is disclosed. The clip applier includes an elongated housing having proximate and distal ends. This housing also defines a feed surface for the surgical clips. The clip applier also includes first and second jaws extending from the distal end of the housing. The jaws open and close to apply the surgical clips to the body tissue of the patient. A driver is disposed within the housing to advance the surgical clips from the feed surface to the jaws. The clip applier of the present invention incorporates a backing surface extending from the distal end of the housing and extending along the jaws. Accordingly, the backing surface bears against the jaws by constantly applying a force such that the housing is always pre-loaded against the jaws. As such, the jaws are maintained in proper alignment with the feed surface and the surgical clips can be advanced from the feed surface to the jaws without a misfeed.

摘要： A laparoscopic introducer and method of use comprise a laparoscopic channel and a guide channel for a secondary instrument. Upon initial insertion of the introducer, the guide channel closely conforms to the body of the introducer so as to only negligibly increase the cross-sectional profile thereof. Following insertion, the guide channel can be distended by means of a dilator. Thus, the guide channel allows a secondary instrument to be inserted into the body to perform laparoscopic procedures wherein the instrument is inserted and utilized along the same longitudinal axis as the laparoscope. Thus, the number of laparoscopic ports are reduced and visual distortions associated with triangulation are avoided. The guide channel is constructed from an extremely thin, but very strong and noncompliant membrane which may also be reinforced by means of a force distribution mechanism. The guide channel may also be provided with guide rails or other tracking mechanisms to ensure accurate and secure advancement of the dilator or secondary instrument. The method of construction of the introducer and an apparatus and method for dilation are also disclosed.
摘要翻译：腹腔镜引导器和使用方法包括腹腔镜通道和辅助器械的引导通道。在引导器初次插入时，引导通道与导引器的主体紧密地一致，以便仅忽略不计地增加其横截面轮廓。插入后，引导通道可通过扩张器扩张。因此，引导通道允许将二次器械插入体内以执行腹腔镜手术，其中该仪器沿着与腹腔镜相同的纵向轴线被插入和使用。因此，减少腹腔镜口的数量，避免与三角测量相关的视觉失真。引导通道由非常薄但非常坚固和不合格的膜构成，其也可以通过力分配机构加强。引导通道还可以设置有导轨或其它跟踪机构，以确保扩张器或辅助仪器的准确和安全的前进。还公开了导引器的构造方法以及用于扩张的装置和方法。
