摘要： A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float, a ballast assembly longitudinally moveable with respect to the float, and a bellows structure. The bellows structure includes a first end, a second end, and a deformable bellows therebetween. The float is attached to a portion of the first end of the bellows structure, and the ballast is attached to a portion of the second end of the bellows structure. The attached float and bellows structure includes a releaseable interference engagement therebetween. The float has a first density, and the ballast has a second density that is greater than the first density of the float.

摘要： A mechanical separator for separating a fluid sample into first and second phases is disclosed. The mechanical separator includes a float having a passageway extending between first and second ends thereof with a pierceable head enclosing the first end of the float, a ballast longitudinally moveable with respect to the float, and a bellows extending between a portion of the float and a portion of the ballast. The bellows is adapted for deformation upon longitudinal movement of the float and the ballast, with the bellows isolated from the pierceable head. The float has a first density and the ballast has a second density greater than the first density. The bellows is structured for sealing engagement with a cylindrical wall of a tube, and the pierceable head is structured for application of a puncture tip therethrough. The separation device is suitable for use with a standard medical collection tube.

摘要： A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

摘要： An endoscopic vacuum controller may include a housing having a vacuum inlet, a vacuum outlet configured to be coupled to a vacuum source, and a vacuum passage fluidly coupling the vacuum inlet to the vacuum outlet. The vacuum controller may also include an actuator supported by the housing and configured to control the flow of fluid through the vacuum passage. An indicator may be supported by the housing to provide an indication that a predetermined vacuum level is being drawn at the vacuum inlet. The vacuum controller may include a connector to detachably couple the housing to an endoscope shaft. The connector may be configured to slidably couple the housing to the endoscope shaft to allow adjustment of the controller along the length of the shaft while the housing remains coupled to the shaft.

摘要： Suture anchor systems for repairing torn or damaged tissue are described herein. In one embodiment, a system can include a first suture loop having a first suture anchor coupled thereto, the first suture loop including a slip knot formed thereon to allow a size of the first suture loop to be adjusted. The system can also include a second suture loop coupled to the first suture loop and having a second suture anchor coupled thereto. The second suture loop can have a fixed size. In use, the suture anchors can be deployed through tissue to be repaired and into the anchoring tissue at a position spaced apart from one another by a selected distance. The length of the first suture loop can then be tensioned to re-approximate the torn or damaged tissue toward the anchoring tissue, thereby securely attached the torn tissue to the anchoring tissue.
