摘要： A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.

摘要： A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).

摘要： Described herein is a shock wave device for the treatment of vascular occlusions. The shock wave device includes an outer covering and an inner member inner connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member. A conductive emitter band circumscribes the ends of the first and second wires to form a first spark gap between the end of the first wire and the emitter band and a second spark gap between the end of the second wire and the emitter band. When the volume is filled with conductive fluid and a high voltage pulse is applied across the first and second wires, first and second shock waves can be initiated from the first and second spark gaps.

摘要： A radiopaque balloon with a composite wall having a radiopaque adhesive affixing inner and outer layers of the balloon. The radiopaque adhesive provides a radiographic image of the balloon wall with or without the use of radiopaque contract media to inflate the balloon. A radiographically fainter image is provided as the balloon is inflated with well-defined edges of a balloon image, and the total radiopacity of the balloon does not change as the balloon is inflated. Also, a method of imaging a balloon wall and a method of imaging a radiopaque adhesive between two layers of a balloon wall are provided.

摘要： A system and method used to deliver a valve delivery system carrying a valve to a target valve annulus in the heart includes a cable percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, transseptally through the heart, to a femoral artery. The valve delivery system device is passed over an end of the cable at the arterial side and is secured to the cable. The valve delivery system device is pushed in a distal direction while the venous end of the cable is pulled in the proximal direction, to advance the valve delivery system to the target valve annulus. A left ventricle redirector positionable on the cable from the venous end has a distal end actively steered during advancement and positioning of the valve delivery device, exerting forces that steer the distal nose of the valve delivery device as it moves towards the valve annulus.

摘要： A balloon catheter for use with a guidewire includes an elongated, tubular shaft extending in a longitudinal direction, said shaft having a proximal end and a distal end. An inflatable balloon is connected to the distal end of the shaft, the balloon including a working surface. A radiopaque identifier is provided for identifying the working surface. A receiver adjacent the proximal end of the shaft is adapted for allowing the shaft to move relative to the receiver in at least the longitudinal direction.
