Abstract:

A separation device including a first buoy, a second buoy, a first valve, and a second valve. The first buoy is mounted to a buoy guide post and slidably mounted within a separation chamber. The second buoy is slidably mounted to the guide post and movable between a first position and a second position. The second buoy closes the first valve and opens the second valve when in the first position. The second buoy opens the first valve and closes the second valve when in the second position. The second buoy has a density such that after spinning the device for a suitable period of time a first component of the composition is isolated between the first buoy and the second buoy and a second component of the composition is isolated between the second buoy and the end of the separation chamber that is opposite to a port.

US Classification:

422547, 422548, 422549, 422561

Abstract:

A transportation system for transporting a biological material container between a sterile field and a nonsterile field and substantially maintaining sterility of the biological material container includes a housing assembly that removably houses the biological material container. The system also includes a port defined by the housing assembly, and the port provides communication into the biological material container from outside the housing assembly. The housing assembly includes a first member that covers a first portion of the biological material container such that a second portion of the biological material container extends from the first member. The housing assembly also includes a second member that covers the second portion of the biological material container. The second member is removably coupled to the first member to expose the second portion of the biological material container. A keying member that keys the transportation system in a centrifuge is also disclosed.

International Classification:

A61B 17/00

US Classification:

606 85

Abstract:

Oscillating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such oscillating rasps are also disclosed. The oscillating rasp includes an attachment head configured to be secured in a chuck of an oscillating tool, and a cutting head secured to the attachment head. The cutting head includes a cutting surface extending posteriorly from the longitudinal axis of the oscillating surgical rasp. The cutting surface has a plurality of cutting teeth arranged in a geometry that, when oscillated along a predetermined path in contact with the glenoid of the patient, corresponds with the geometry of the augmented glenoid prosthesis.

International Classification:

A61M 37/00

US Classification:

604 82

Abstract:

A system for expressing two materials onto a selected site is disclosed. The system can include a syringe that is operable to maintain two separated materials substantially separate until a selected time. The system can further include a tip portion operable to direct the two materials, either mixed or unmixed, to a selected site. The materials can include tissue sealants, growth factors, or other appropriate materials to be directed to a selected site.

Abstract:

Extracting or removing at least a portion of liquid phase from a whole sample using a centrifugal force is disclosed. Centrifugal forces are used to apply pressure to a whole sample and drive a liquid phase through a passage region that can be perforated and/or porous and maintain a drier portion within a separation container. The whole sample can be dried, which includes a remaining sample where excess or a selected amount of liquid is removed. Direct access to the separation container or area can then be made to provide for an efficient withdrawal of the drier material from the separation container.

US Classification:

435 13

Abstract:

A method for preparing and isolating clotting serum. The method includes adding reagent and a clotting serum source to a reaction chamber of a clotting serum production device that includes an activator. The reagent, clotting serum source and activator are mixed by shaking the serum production device to bring the contents to a foam. The serum production device is placed in either a vacuum or at room temperature for a period of time, and the clotting serum is extracted from the reaction chamber.

Abstract:

A separation system for separating a multiple component material into at least two fractions. The separation system includes a separation device having a first end, a second end opposite to the first end, and a sidewall that extends between the first end and the second end to define a separation chamber having an interior volume. The system also includes a valve moveable between an open position and a closed position, the valve is mounted at a fixed location within the separation chamber at a position that is closer to the second end than to the first end and is spaced apart from the second end, the valve is operable to isolate a first fraction of the multiple component material having a first density on a first side of the valve from a second fraction having a second density on a second side of the valve that is opposite to the first side.
