摘要:
An automated analytical apparatus comprises an introduction station for receiving a plurality of reagent packages. Each package has a plurality of receptacles, at least one of which includes a sample liquid to be analyzed, and at least one of which includes a liquid reagent for forming a reaction mixture with the sample liquid. A liquid transfer station is included for transferring liquid contained in one or more receptacles of a reagent package into, out of or among different receptacles thereof, including the formation of the reaction mixture. A detector is provided for detecting a characteristic of the sample by analyzing the reaction mixture contained in one of the receptacles of a package. A storage area is included within the apparatus for storing a plurality of reagent packages. A shuttle system transports individual reagent packages in any order and in any direction between the introduction area, the liquid transfer station, the detector and the storage area.

A sleep surface insert system and method for positioning under, for example, an infant on a sleep surface. The sleep surface insert system includes an insert and a blower system. The insert includes a top liner and a bottom liner. The top liner and bottom liner define first and a second hollow spaces therebetween. Further, the top liner includes first and second pores such that the first pores extend through the top liner from the first hollow space and the second pores extend through the top liner from the second hollow space. In addition, the blower system is configured to provide air flow into the first and second hollow spaces defined in the insert such that the air flow is configured to flow into the insert and out of at least one of the first pores and the second pores.

A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The closure device can include a body portion operatively associated with a first anchor and a second anchor. The body portion can include a plurality of segments defining a multi-cellular structure. The closure device can be configured to apply lateral force to tissue of the internal tissue opening to bring tissue together. The closure device can have a substantially flat aspect, and have a depth thickness that is substantially greater than the thickness or width of a majority of the members forming the closure device to reduce out of plane bending. The closure device can also include a member adapted to induce tissue growth.

The present invention is directed to various embodiments of medical devices and methods for occluding a fallopian tube for contraception and permanent sterilization. In one embodiment, the medical device includes an outer member, an inner member and a tissue growth member. The outer member includes an outer surface and an inner surface, wherein the inner surface defines a bore in the outer member. The inner member is configured to be positioned within the bore of the outer member. The tissue growth member is attached to the outer surface of the outer member and is configured to induce tissue growth thereto. With this arrangement, the medical device can be implanted within the fallopian tube and serve as a permanent occluding device therein. If desired, the medical device can be partially removed from the fallopian tube to restore the ability for conception.

Several embodiments are set forth of devices, systems and methods for modifying an atrial appendage such as a left atrial appendage (LAA). In one embodiment, a device includes a body that is collapsible and self-expanding. The body includes a textured surface with protruding portions and recessed portions. The body may be formed of a reticulated foam material and may exhibit a substantially spherical geometry or a truncated spherical geometry. The body may be substantially hollow. In one embodiment, portions of the textured surface may be metalized or have a coating placed thereon to enhance frictional engagement of the body with the atrial appendage wall. In another embodiment, a mesh bag is disposed within an LAA and one or more self-expanding bodies are disposed within the mesh bag. The mesh bag is then secured to retain the self-expanding bodies within the bag and the LAA.

A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The closure device can include a multi-cellular body portion operatively associated with a first anchor and a second anchor. The closure device can be configured to apply lateral force to tissue of the internal tissue opening for tissue approximation. The closure device can have a substantially flat aspect, and have a depth that is substantially greater than the thickness of a majority of the members forming the closure device. The closure device can also include an in-growth material. The delivery device can include an actuating assembly configured to partially deploy the closure device by a first movement, and deploy a second portion of the closure device by a second movement. The delivery device can also include a release assembly to selectively release or disconnect the closure device from the delivery device.
