    • According to one aspect of the invention, a method of forming a medical device is provided, which includes: (a) contacting a substrate with a solution that contains (i) one or more types of polymers, (ii) a solvent that contains one or more types of solvent species, and (iii) one or more optional agents, for example, one or more therapeutic agents, among others; and (b) removing the solvent from the solution, thereby forming a polymeric layer on the substrate. The composition of the solution is changed over the course of forming the polymeric layer. In another aspect of the invention, a medical device is provided, which includes a substrate and a polymeric layer over the substrate. The polymeric layer contains a copolymer that contains differing first and second monomers. The lower surface of the polymeric layer contacting the substrate has a surface concentration of the first monomer relative to the second monomer that is higher than that of the upper surface of the polymeric layer opposite the substrate.
    • 根据本发明的一个方面,提供了一种形成医疗装置的方法,其包括:(a)使基底与含有(i)一种或多种聚合物的溶液接触,(ii)含有一种 或更多类型的溶剂物质,和(iii)一种或多种任选的试剂,例如一种或多种治疗剂等; 和(b)从溶液中除去溶剂,由此在基材上形成聚合物层。 在形成聚合物层的过程中改变溶液的组成。 在本发明的另一方面,提供了一种医疗装置,其包括衬底和在衬底上的聚合物层。 聚合物层含有含有不同的第一和第二单体的共聚物。 与基材接触的聚合物层的下表面具有相对于第二单体的第一单体的表面浓度高于与基材相对的聚合物层的上表面的表面浓度。

    • A stent delivery system for deployment at a bifurcated vessel includes a catheter and a balloon. The length of the balloon is defined by a proximal balloon region and a distal balloon region. The proximal balloon region is disposed about a first longitudinal axis and the distal balloon region is disposed about a second longitudinal axis. The balloon has an unexpanded state and an expanded state, and a bend along its length. The proximal balloon region intersects the distal balloon region at the bend. In both the unexpanded state and the expanded state, at least one of the first longitudinal axis and the second longitudinal axis define an oblique angle relative to the main vessel longitudinal axis.
    • 用于部署在分叉血管的支架输送系统包括导管和气囊。 球囊的长度由近端球囊区域和远端球囊区域限定。 近端球囊区域围绕第一纵向轴线设置,并且远端球囊区域围绕第二纵向轴线设置。 气球具有未膨胀的状态和膨胀的状态,并且沿其长度弯曲。 近端气囊区域在弯曲处与远端球囊区域相交。 在未膨胀状态和膨胀状态下,第一纵向轴线和第二纵向轴线中的至少一个限定相对于主容器纵向轴线的倾斜角度。

    • A process and apparatus for planting aquatic plants underwater on the bottom of estuaries in damaged areas and for encouraging plant growth in seabeds and banks. Aquatic plant shoots are transplanted by positioning shoots in a sediment container which is in turn placed in the targeted area. When the sediment container is placed, the sea grass shoots are held in position for an extended period of time to allow the sea grass shoots to take root. The sediment containers may be preformed or they may be formed just prior to their placement. A watercraft may be used to position the sediment containers with and without sea grass shoots over an area of the propeller scar. With the process and apparatus of this invention, sea grass plants can be cultivated. Further in accordance with another embodiment of this invention a container or other obstruction without plant is placed to impede water flow over the area being cultivated. When water flow is impeded natural plant growth is encouraged.
    • 用于在受损区域的河口底部水下种植水生植物的过程和装置,并鼓励海底和银行植物生长。 通过将沉淀物定位在沉淀物容器中并将其放置在目标区域中来移植水生植物芽。 放置沉积物后,海草长时间保持在适当位置,使海草扎根。 沉淀物容器可以预先形成,或者它们可以在其放置之前形成。 可以使用船只将含有和不具有海草芽的沉积物定位在螺旋桨疤痕的区域上。 利用本发明的方法和装置,可以栽培海草植物。 此外,根据本发明的另一个实施例,放置没有植物的容器或其他阻塞物以阻止水被流经被培养的区域。 当水流阻碍时,鼓励天然植物生长。

    • A bearing seal assembly includes a pair segmented circumferential or a carbon ring seals to contain oil in the bearing compartments of a gas turbine engine or other mechanical device. The pair of seals, an oil-side seal and an air-side seal, are axially-spaced between the oil and the air in the housing. Air at an elevated pressure is introduced between the seals. This elevated air pressure urges the seals axially apart from one another and radially inward to improve the seal. A backup seal is provided adjacent either the oil-side seal or the air-side seal. In the event of failure of either the oil-side seal or the air-side seal which results in the loss of air pressure, the backup seal will provide at least a minimum level of seal between the oil compartment and the air in the housing.
    • 轴承密封组件包括一对分段圆周或碳环密封,以在燃气涡轮发动机或其它机械装置的轴承隔室中容纳油。 一对密封件,油侧密封件和空气侧密封件在壳体中的油和空气之间轴向间隔开。 在密封件之间引入高压空气。 这种升高的空气压力迫使密封件彼此轴向地分开并径向向内以改善密封。 在油侧密封件或空气侧密封件附近设置备用密封件。 在导致空气压力损失的油侧密封件或空气侧密封件发生故障的情况下,备用密封件将在油室和壳体中的空气之间提供至少最小程度的密封。
