Abstract: Example medical systems useful in performing treatment under magnetic resonance imaging and related devices, kits, and methods are described. An example medical system includes a first medical device and a second medical device. The first medical device has a first passive marker. The first passive marker is formed of a first material that has a first magnetic susceptibility. The second medical device has a second passive marker. The second passive marker is formed of a second material that has a second magnetic susceptibility. The second passive marker creates an image artifact under MRI. The image artifact created by the second passive marker is altered under MRI when the first passive marker overlaps the second passive marker.

Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.

Abstract: Disclosed are embodiments of devices and methods for imaging the inside of a body part, such as a blood vessel. In particular embodiments, a catheter has a chamber within which is a transducer. A wire guide channel extends throughout the length of the catheter. The transducer is rotatable about the wire guide channel and the transducer is driven by a cable or other device that is connected to a motor which is located outside the catheter. In one form, a torque cable connects the transducer to the motor. In other embodiments, a pusher piece having a plurality of lumens is positioned in the catheter. Each of the lumens is sized to receive a cable, wire, and/or flushing fluid. The lumens maintain the orientation and separation of the cables, wires, and/or to flushing fluid.

Abstract: Differential pressure material processing systems, apparatus, methods, and products are described. An example embodiment of a differential pressure material processing system includes a tank, a holding member, and a sheet of tissue disposed within the holding member. The holding member defines a first holding member chamber and a second holding member chamber. The first holding member chamber has a first pressure when a fluid is disposed within the first holding member chamber. The second holding member chamber has a second pressure when a fluid is disposed within the second holding member chamber. The second pressure is different than the first pressure.

Abstract: Devices and methods for obtaining a real-time, three-dimensional image of a body part, particularly a blood vessel. A catheter has a chamber in its tip. The chamber contains an ultrasound transducer and reflector which generally face each other and rotate about a common axis. The transducer element on the transducer and the reflective face on the reflector are both tilted off-axis. The difference in angular velocity generally creates a phase shift between the transducer and the reflective face. The phase shift allows the transducer and the reflective face to actively scan a three-dimensional volume that is generally bounded interiorly by a hyperboloid and exteriorly by the effective range of the ultrasound beam. The transducer and reflector may rotate at constant speeds or nonconstant speeds as well in the same direction or in opposite directions.
