US 7,407,631 B2 · Apparatus and method for agitating a sample during in vitro testing

Abstract

In an apparatus and method for agitating a sample during dissolution or other in vitro testing, a movable component is disposed in a container for reciprocating or rotating a sample carrier such as a dosage form or stent through a medium in the container. The apparatus can include a closure member to seal the container for substantially preventing loss of contents during movement of the sample carrier. The movable component can be actuated by a driving source in a non-contacting manner. The movable component can include a magnet drivable by a source external to the container. The container can include first and second container sections having different volumes, in which case actuation of the movable component causes agitation of the sample carrier through a medium contained in one of the container sections. The container can include a hole at or near the bottom for filling the container, using instruments, and the like.

Dependent claims

An apparatus for actuating movement of an implantable medical device during in vitro testing, the apparatus comprising:

a movable component including means for holding the implantable medical device in a container during movement of the movable component in the container, wherein the implantable medical device holding means includes a body, a first support member and a second support member, the first and second support members attached to the body and axially spaced from each other for securing the implantable medical device between the first and second support members, and wherein at least one of the first and second support members is axially adjustable along the body for varying the space between the first and second support members;
and
a drivable component attached to the implantable medical device holding means, the drivable component including means for actuating the drivable component and the implantable medical device holding means to move together in the container, the actuating means responsive to non-contacting coupling with a driving source disposed entirely outside the container.
