    摘要： A blood collection vessel includes a blood inlet, a pooling region in which blood from the inlet collects, and an outlet in the pooling region for reinfusion of the collected blood. A filter located in the blood path between inlet and outlet extends at least in part into the pooling region and impounds clots so they remain away from the outlet but suspended in the collected blood. Preferably, the filter is located to provide venting between both sides of the filter. In one embodiment the filter is a vertical wall, which defines a shielded outlet column or chimney extending above the outlet. Blood permeates to the outlet region over a broad area, and the column forms an open suction path that prevents suction differentials from arising across the filter, so clots cannot be sucked through the large-pore material. With the clots residing in the collected fluid, the total fluid loss is directly displayed in a single window at all times, and maximal use is made of the limited volume in the vessel. In another embodiment, the filter constitutes a false floor or basket in the pooling region. A preferred construction employs filter material on a support grid, to form a flexible and self-supporting filter sheet, which inserts like a plate to compartmentalize the collection vessel and form an impounding surface in the pooling region.

    摘要翻译： 血液采集容器包括血液入口，来自入口的血液收集的汇集区域以及汇集区域中用于回收血液回输的出口。 位于入口和出口之间的血液路径中的过滤器至少部分地延伸到汇集区域中并扣留凝块，使得它们保持远离出口但悬浮在收集的血液中。 优选地，过滤器被定位成在过滤器的两侧之间提供排气。 在一个实施例中，过滤器是垂直壁，其限定在出口上方延伸的屏蔽出口塔或烟囱。 血液在大面积上渗透到出口区域，柱形成一个开放的吸入路径，防止吸入差异跨越过滤器，因此凝块不能通过大孔材料吸入。 在收集的液体中存在凝块的情况下，总的流体损失始终直接显示在单个窗口中，并且最大限度地利用了容器中有限的体积。 在另一个实施例中，过滤器构成汇集区域中的假地板或篮子。 优选的结构是在支撑格栅上使用过滤材料，以形成柔性和自支撑的过滤片，其将类似板的插入物分隔成收集容器并在汇集区域中形成蓄水表面。

    摘要： A fluid recovery system, such as a chest or thoracic cavity drain, having a collection chamber for collecting fluid from a patient includes a base and a front face having a translucent portion for viewing the collected fluid and monitoring operation of the system. The front face is coupled to the base at an acute angle to facilitate viewing of the collected fluid, and measurement of the fluid volume, from a position substantially above the fluid recovery system. Additionally, a column insert can be positioned within the collection chamber to collect an initial volume of the fluid and to allow precise determination of its volume.

    摘要： A radially expandable fluid delivery device for delivering a fluid to a treatment site within the body is disclosed. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device. The fluid delivery device includes a tubular member defined by a wall having a thickness transverse to the longitudinal axis of the tubular member and extending between an inner and an outer surface. The wall is characterized by a microstructure of nodes interconnected by fibrils. The tubular member is deployable from a first, reduced diameter configuration to a second, increased diameter configuration upon the introduction of a pressurized fluid to the lumen. The tubular member includes at least one microporous portion having a porosity sufficient for the pressurized fluid to permeate through the wall. Substantially all of the nodes within the microporous portion are oriented such that spaces between the nodes form micro-channels extending from the inner surface-to the outer surface of the wall.

    摘要： A method and apparatus relating to a biocompatible soft tissue implant is disclosed. The implant, in the form of a prosthesis, is constructed of a knitted pile mesh material arranged into either a 3-dimensional structure or a planar shape or structure. The material or fabric includes a plurality of filament extensions projecting outwardly therefrom. The filament extensions can be radially projecting looping filaments from one or more rows of the knitted pile mesh material. The combination of the filament extensions with the 3-dimensional structure results in the biocompatible implant having a structural resistance to hinder anticipated crushing forces applied to the implant, and also provide a suitable 3-dimensional structure for promoting rapid tissue in-growth to anchor such implant without migration and strengthen the repaired tissue area.
