摘要： A method of curing and corresponding resulting non-polymeric cross-linked gel are provided. The cross-linked gel can be combined with a medical device structure. The cross-linked gel can provide anti-adhesion characteristics, in addition to improved healing and anti-inflammatory response. The cross-linked gel is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel derived from at least one fatty acid compound. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent. The curing method can vary the application of heat in both temperature and duration to achieve a desired amount of cross-linking forming the gel.

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.

摘要： A blood collection device has a modular suction regulator assembly in the form of an adjustable negative pressure relief valve which controls the level of suction in a collection chamber by admitting air to a short bleed-in passage proximate to a suction connection. The modular assembly is a canister which drops into a receptacle oriented transversely in the collection vessel, and defines a laterally-directed intake manifold which resists blockage. The intake passes centrally through the canister along a path spanned by a filter, past a hat-shaped poppet supported on a compression spring. Fluted and threaded members control the scale and range of poppet response so that the assembly may be calibrated before installation. A face plate covers the installed canister, and radial vanes in the intake manifold double as gripping elements for manual adjustment of the assembly. A bellows meter provides refined suction resolution by linearly advancing across an oblique or curved reference line. Other improvements include a compact and balanced layout of suction canister, seal chamber and collection chamber, and a rigid handle assembly having five faces integral with the device.

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： A drainage device includes a vessel having a plurality of sub-chambers one of which is a regulated drainage collection chamber, and two of which cooperate to maintain a selected suction level in the drainage collection chamber. A stopcock proximate to the vessel communicates directly with the two cooperating sub-chambers, and allows quick adjustment and stable operation in varying environments. A float ball arrangement provides an indication of water loss that may compromise the water seal. The device is suitable for wound drainage, and may be used as a cardiotomy reservoir or a thoracic cavity drain device. Different embodiments collect blood for autologous infusion.

摘要： Apparatus for blood collection includes a collection bag with a suction inlet, a fluid inlet, and an outlet, and an internal stent that resiliently biases the bag into a fixed shape while moving to modulate abrupt variations in suction level. A gross filter about the outlet is located out of the suction path, eliminating blood damage from drying or cell trauma. Different graduation scales show the true volume of collected fluid under suction conditions during collection and with no suction during reinfusion. Two quick-connects allow in-line connection with a chest drain to provide suction, and mate with each other to close the inlets when the filtered bag is removed for gravity reinfusion. When multiple units are piggy-backed, they fill sequentially and may be removed for reinfusion quickly, with only a single tube reconnection required during surgery.

摘要： A thoracic cavity drainage device includes a first vessel having a plurality of chambers one of which is a regulated drainage chamber, and a separate transfer vessel which receives fluid collected in the drainage chamber of the first vessel. The chambers of both vessels are interconnected in a series by fluid passageways which cooperate to maintain a uniform range of suction in the drainage chamber while preventing passage of water into the drainage chamber and permitting a different level of suction in the transfer vessel. This operation is effective despite relatively large pressure and vacuum impulses caused by stripping of drainage lines, patient coughing, and the like, and despite discrete changes in the physical configuration of the system caused by disconnection of the transfer vessel, connection of the transfer vessel to an infusion line or the opening or closing of fluid lines and ports. A novel transfer vessel empties the drainage device and provides gravity reinfusion of the collected fluids. A mechanism within the transfer vessel provides an effective suction without vacuum connections or pressure regulating adjustments.

摘要： Disclosed are the product and method for making a macroscopically smooth, microporous, flexible, elastic tubular prosthetic device from a substantially non-elastic woven fabric tube. The method involves axially compressing the substantially non-elastic tube on a tight fitting cylindrical mandrel so that the individual axially oriented threads of the fabric form loops projecting radially outwardly between circumferential threads. The threads are set to return to this loop configuration upon release of tension applied axially to the tube. The exterior of the tube presents an easily deformed, macroscopically smooth surface having a multiplicity of interstices among the threads and among the fibers of the threads into which cells can grow after implantation.

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.
