摘要： An intraluminal imaging catheter system for viewing segments of vessels downstream of the catheter itself is provided. The catheter system incorporates an ultrasonic transducer pivotally mounted adjacent the catheter's distal end. A flexible drive means disposed within a flexible tubular member adapted for insertion into the vessel causes the transducer to pivot back and forth to scan a segment of the vessel. Optionally, the forward viewing catheter system of the present invention may be combined with a work element such as a biopsy tool or other device for use in conjunction with the imaging capability.

摘要： A dental condensing instrument having an elastomeric tip of sufficient size to surround the margins of a prepared cavity, which will yieldably urge the flow of soft restorative materials inside prepared cavities to improve their adaptation to cavity walls and margins without the introduction of deleterious air voids therein. When hand pressure is applied, the tip will not only seal said margins, but also apply a steady, isostatic condensing force upon said materials.

摘要： An improved catheter system having an ultrasonic imaging transducer coupled to a drive cable disposed within a lumen of a flexible tubular catheter body. An improvement including a reconfiguration of the ferrites in the hub assembly, such that the need for the gap between the ferrites is removed. A strain relief member is provided to increase the strength of the electrical transmission lines to enable them to withstand the tensile forces caused by either flushing and/or pull-back operations. A device which allows the electrical transmission lines to extend their length when placed in tension may also be employed to provide strain relief to the electrical transmission lines. Another improvement includes a counter-wound coil structure, which may either expand or contract as the drive cable is being rotated to strengthen the drive cable. The distal tip of the catheter body may be redesigned to provide a lumen which allows for the release of flushing fluids through a distal port in the guidewire lumen.

摘要： Devices and methods for percutaneous translumenal minimally invasive coronary surgery, particularly bypass surgery involving the following basic steps: determining a proper location for treatment, navigating a suitable device to the treatment site, creating an extravascular opening and pathway, guiding and/or monitoring the progress of creating the opening and pathway, and maintaining the extravascular opening and pathway. One or more extravascular openings and/or pathways may be created to define a fluid path or bypass around the vascular restriction. For example, an intravascular catheter for creating an extravascular opening in a vessel wall includes an elongate shaft adapted for intravascular navigation, an anchoring mechanism disposed on the distal end of the shaft, and a tissue penetrating member having a proximal end slidably disposed in the shaft and a distal end including a tissue penetrating mechanism.

摘要： An apparatus for delivering a closure element into an opening formed in a blood vessel or other body lumen and methods for manufacturing and using same. The apparatus is configured to retain the closure element such that the closure element is disposed substantially within the apparatus. The apparatus also can engage, and position the closure element substantially adjacent to, the blood vessel wall adjacent to the opening. During deployment of the closure element, the apparatus expands the closure element beyond a natural cross-section of the closure element such that the closure element, when deployed, is configured to engage a significant amount of the blood vessel wall and/or tissue. Engaging the blood vessel wall and/or tissue, the closure element is further configured to return to the natural cross-section, thereby drawing the engaged blood vessel wall and/or tissue substantially closed and/or sealed, such that hemostasis within the opening is enhanced.
