Abstract: A catheter assembly and related methods include first and second catheter branches that are configured to travel over separate guidewires to a vessel bifurcation treatment site within a patient. The catheter branches can each include a plurality of markers. The position of markers on one catheter branch relative to the position of markers on the other catheter branch provide a visual indication of relative twist between the catheter branches, can help distinguish one catheter branch from the other, and help with visual alignment of the catheter branches relative to the vessel bifurcation.

Abstract: Medical devices that include micromachined hypotubes or that have themselves been micromachined can provide advantages in flexibility, strength and other desirable properties. Examples of such medical devices may include catheters such as guide catheters and balloon catheters. Such devices may also include dual shaft medical devices in which an outer shaft is reversibly lockable onto an inner shaft.

Abstract: An intravascular balloon catheter that may include, for example, a first elongate member having a proximal end, an opening at the distal end and a lumen therebetween, a balloon defining a cavity, the balloon having a proximal waist sealingly attached to the first elongate member proximal the distal end, a distal waist, and a tubular portion therebetween, a second elongate member having a proximal end, a distal end and a lumen therebetween, the second elongate member disposed in the first elongate member and sealingly attached to the balloon distal waist, and a stopper attached to the second elongate member and disposed in the balloon cavity distal the distal end of the first elongate member, the stopper having an outer profile that prevents movement of the first elongate member thereover the first elongate member having an inner diameter at the distal end large enough to permit the passage of fluid therethrough over the second elongate member.

Abstract: A medical appliance is provided that includes a self-expanding stent; a sheath adapted to enclose the self-expanding stent in an interior space during deployment; and an external body comprising a bioactive agent attached to the self-expanding stent and adapted to lie outside the interior space of the sheath when the self-expanding stent is enclosed in the sheath. The medical appliance may be deployed in a lumen of a human body and the external body may release the bioactive agent. A method of producing a medical device is provided that includes attaching an external body to a stent and coupling the stent to a delivery arrangement. The external body includes a bioactive agent.

Abstract: A stand alone sensor module having built in intelligence that provides object detection for a both a vehicle and stationary applications. The system includes a processor connected to a sensor and a signal interface. The processor receives signals from the sensor and the signal interface and generates a status signal based on the signals received from the sensor and the signal interface. The processor drives the status signal to the signal interface.

Abstract: A collision avoidance system including a control module, a first transmitting device connected to the control module, wherein the first transmitting device transmits a signal, a first receiving device connected to the control module, wherein the first receiving device receives a return of the signal transmitted from the first transmitting device and transmits a first return signal representative of the return to the control device, a second transmitting device connected to the control module, wherein the second transmitting device transmits a signal, and a second receiving device connected to the control module device, wherein the second receiving device receives a return of the signal transmitted from the second transmitting device and transmits a second return signal representative of the return to the control device, wherein the control module includes measurement circuitry used to measure the first and second return signals and display means for displaying a transverse location of an object as a function

Abstract: A medical device comprises a catheter having a catheter shaft, a sheath and a rolling membrane. The sheath is being disposed about the catheter shaft and is longitudinally moveable relative thereto. A distal portion of the sheath defines a stent retaining region. The sheath is moveable between an extended position and a retracted position, wherein in the extended position the retaining region is disposed about a stent receiving region of the catheter shaft, and in the retracted position the sheath is removed from the stent receiving region. End regions of the rolling membrane are respectively engaged to a distal end of the sheath and a portion of the shaft proximal to the stent receiving region respectively.

Abstract: Catheters, as well as related systems and methods are disclosed.

Abstract: A trailer based collision warning system includes one or more side object detection sensors, one or more backup assist sensors, a driver vehicle interface, and trailer-mounted display units operating essentially independent of the tractor with all detection and warning system equipment mounted on the trailer. The trailer based collision warning system is coupled to industry-standard tractor to trailer wiring to provide the trailer with power and signals such as left turn indication and right turn indication. The side and rear sensors detect the presence and location of objects and transfer this information to a driver vehicle interface device located on the trailer. The system can also be equipped with video cameras with a means of automatically activating the camera in the area where a hazard condition has been detected.

Abstract: A system for reducing the diameter of a stent comprises a stent contracting assembly and a fluid source. The assembly comprises a plurality of contracting members that define a diameter reduction chamber for receiving a stent. When the chamber is in a pre-reduction configuration the stent has a first diameter and when the chamber is in a reduced configuration the stent has a second diameter. The second diameter is less than the first diameter. The fluid source is in fluid communication with the chamber and is constructed and arranged to inject a fluid therein. The fluid forms a fluid bearing between the contracting members and the stent which prevents the contracting members from contacting the stent in the reduced diameter configuration.
