    • This invention relates to a method of making an inflatable bone plug for plugging the open end of an intramedullary bone canal which is capable of restricting the flow of bone cement, particularly, during the insertion of bone cement, particularly during the pressurized injection of such a cement, during an operative procedure involving the fixation of the stem of an artificial joint prosthesis such as a femoral hip joint prosthesis to the end of a bone such as a femur. The bone plug is designed to be pressurized with a biocompatible fluid and to thereafter deflate in a controlled manner after the cement hardens. Preferably, the bone plug is made by forming a hollow expandable container of a silicone elastomer permeable to carbon dioxide gas which has a valve stem attached to one end of the container and an opening at the opposite end of the container. A shrinkable elastomeric band is placed over the valve stem in which a channel has been made to receive a further cooperating injection means such as a needle. The elastomeric band shrinks over the valve stem to form a resealable valve assembly. The valve assembly is located in the hollow interior of the bone plug and the opening opposite the valve stem is sealed to complete construction of the bone plug. When such a plug is inflated with a biocompatible fluid such as carbon dioxide, the plug remains pressurized for a sufficient amount of time to allow the cement to harden, but the pressure drops to a minimum within about 24 hours after inflation.
    • 本发明涉及一种制造用于堵塞髓内骨管的开口端的可膨胀骨塞的方法,该骨塞能够限制骨粘固剂的流动,特别是在插入骨粘固剂期间,特别是在加压注射骨粘固剂期间 水泥,包括将诸如股骨髋关节假体的人造关节假体的杆固定到诸如股骨的骨的末端的手术过程中。 骨塞设计成用生物相容性流体加压,然后在水泥硬化后以受控的方式放气。 优选地,骨塞是通过形成可渗透二氧化碳气体的硅氧烷弹性体的中空可扩张容器制成的,其具有连接到容器的一端的阀杆和在容器的相对端的开口。 将可收缩的弹性体带放置在阀杆上方,在该阀杆上已形成通道以接收进一步协作的注射装置,例如针头。 弹性带收缩在阀杆上以形成可重新密封的阀组件。 阀组件位于骨塞的中空内部,并且与阀杆相对的开口被密封以完成骨塞的构造。 当这样的塞子用诸如二氧化碳的生物相容性流体充气时,塞子保持加压足够的时间以允许水泥硬化,但在充气后约24小时内压力降至最低。

    • An improvement in the implantable shunt device of the type disclosed in U.S. Pat. No. 4,181,132 wherein each valving slit within the elastomeric body of the shunt is formed by a flattened sleeve of woven vascular prosthesis material presenting opposed interior surfaces interengaged when the valving slit is in a closed condition and spaced apart when the valving slit is in an open condition. The opposed surfaces of the sleeve are formed by a material having a coefficient of friction with respect to the material of the cannula insertable therethrough less than that of the elastomeric material of the body. A separate yieldable bias operable in addition to the bias provided by the elastomeric material of the body is provided for yieldably biasing the opposed surfaces of the flattened sleeve into sealed relation when in the closed interengaged condition and into sealed relation to the exterior periphery of the portion of the cannula extending therethrough when in the open spaced apart condition. The additional bias is provided by filling under pressure opposed cavities in the elastomeric body with a yieldable material so located with respect to the flattened sleeve as to transmit the pressure thereof as the additional bias of the opposed surfaces into sealed relation when in the closed interengaged condition and into sealed relation with the exterior periphery of the cannula when in the open spaced apart condition.

    • In accordance with a preferred embodiment of this invention, there is provided a new and improved method of forming a four-lumen gastrointestinal tube. This tube may be characterized as having two lumens which extend nearly the full length of the tube and two lumens which extend through only a portion of the tube. The subject method comprises the steps of: (1) extruding a three-lumen sleeve portion wherein one of the lumens is an insert carrying lumen and the remaining two lumens, in the final gastrointestinal tube assembly, are those lumens which extend the full length of the tube; (2) extruding a two-lumen insert portion, the lumens of which in the final gastrointestinal tube assembly, extend the full length of the assembly, and wherein the external dimensions of the insert portion are slightly larger than the internal dimensions of the insert carrying lumen of the sleeve portion; (3) immersing the sleeve portion in a solvent, preferably chlorothene, to cause it to swell until the internal dimensions of the insert carrying lumen are slightly larger than the external dimensions of the two-lumen insert portion; (4) inserting the insert portion into the insert carrying lumen; and (5) removing the solvent and thereby causing the insert carrying lumen in the sleeve portion to contract around the insert portion forming a "solvent shrink fit."
