摘要： An adjustable length cannula (10) which may be longitudinally extended or retracted in order to accommodate a range of body cavity wall thicknesses. A method for inserting the cannula (10) is disclosed, in which a guiding cannula (260) is placed into the peritoneal cavity using the insufflation needle (250) as a guidewire, and a screw dilator (270) and cannula (10) are then placed into the peritoneal cavity using the guiding cannula as a guidewire. The guiding cannula (260) also allows visual inspection of the peritoneal cavity with an endoscope prior to insertion of the dilator (270)/cannula (10) in order to verify proper clearance.

摘要： Disclosed is an ergonomically improved hypodermic syringe (10) which facilitates one handed use by allowing the same hand that holds the syringe to operate the plunger (20) conveniently to accomplish both the distal (injecting) stroke, and the proximal (aspirating) stroke. The syringe includes a pair (6, 7) of finger stop structures on diametrically opposite sides of the barrel which block slippage in both proximal and distal directions, which do not occupy the barrel's entire circumference, and do not interfere with the legibility of a calibration scale (11) that passes through the region of the barrel with which said structures are associated. A loop (25, 26) atop the syringe's plunger member is also provided, which is adjustable to vary the size of the aperture thereof for a snug fit with fingers and thumbs of varying sizes. In combination, the adjustable loop and finger stops make the syringe plunger easily operable in both directions with one hand. The result is a syringe which is inexpensive to manufacture, which is compact to store and ship, and which enables an aspiration maneuver to test for the presence of blood indicating that a blood vessel has been penetrated, to be performed easily with one hand.

摘要： Methods and systems for introducing articles and surgical instruments to target body cavities, utilize conformable sleeves which are percutaneously positioned within the cavity. Articles (44) may then be passed directly through the conformable sleeve (12) without use of a rigid cannula, either by pushing the articles (44) inwardly through the sleeve (12) using an introducer, or pulling the articles (44) inwardly through the sleeve using a tapered carrier. Surgical instruments are also passed directly inwardly through the sleeve. Such systems and methods may be used in a variety of minimally invasive surgical procedures.

摘要： A fluid gas removal drip chamber (10) for use for parenteral administration of fluids is disclosed. The drip chamber has a hydrophobic barrier (28) which extends into the interior of the drip chamber. The hydrophobic barrier preferably comprises at least a portion of a three-dimensional surface. In one embodiment, an inlet port (14) allows fluid to enter the drip chamber from the top of the drip chamber. By shaping the inlet port so that droplets of fluid are formed, a health care professional can monitor the fluid drip rate. In another embodiment, the hydrophobic barrier is configured so that little or no air space exists at the top of the drip chamber. The drip chamber includes means for venting air that is separated from the fluid within the chamber and, at the same time, preventing air from entering the chamber through the venting means. For certain applications, the drip chamber is provided with a hydrophobic filter (68) for filtering the fluid prior to exiting the drip chamber.
摘要翻译：公开了一种用于肠胃外给药流体的流体气体去除滴液室（10）。滴水室具有延伸到滴水室内部的疏水屏障（28）。疏水屏障优选地包括三维表面的至少一部分。在一个实施例中，入口（14）允许流体从滴液室的顶部进入滴注室。通过使入口端口成形以形成液滴，保健专业人员可以监测流体滴落率。在另一个实施方案中，疏水屏障被配置为使得在滴液室顶部存在很少或没有空气空间。滴水室包括用于排出空气的装置，其与室内的流体分离，并且同时防止空气通过排气装置进入室。对于某些应用，滴注室设有疏水过滤器（68），用于在离开滴水室之前过滤流体。

摘要： This invention is a valve apparatus (10) and method with an elastomeric disk (10d) fixedly disposed between the inlet (11) and outlet (12) members and being deformable to permit flow through the inlet (11) to the outlet (12). Deformation of the disk (10d) in the direction of pressure through the outlet (12) is limited. The elastomeric disk (10d) can be circular with a linear or nonlinear slit (S) and be clamped between the inlet and outlet members. The structure for limiting disk deformation can take the form of a pilot (12-3) integrated into, and extending across, the inlet member in centrally or non-centrally aperture form.
