摘要： An example medical device delivery system is disclosed. The delivery system includes an inflation shaft having a first lumen, a second lumen and a distal end region, the distal end region including an elongated tip. The delivery system also includes a detachment shaft extending along a portion of the inflation shaft. The delivery system also include a delivery shaft having a proximal end region, a distal end region and a lumen extending therein. The delivery system also includes an occlusive member positioned within at least a portion of the lumen of the delivery shaft, wherein the occlusive member is configured to expand and seal the opening of a left atrial appendage. Further, a portion of the elongated tip is removeably engaged with the occlusive member.

摘要： Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft having a proximal end region and a distal end region. A first lumen may be defined in the shaft. A second lumen may be defined in the shaft. The distal end region may include a common lumen region in fluid communication with the first lumen and the second lumen. A deflectable member may be disposed within the shaft. The deflectable member may be designed to shift between a first configuration where the deflectable member directs a first medical device disposed within the common lumen region into the first lumen and a second configuration where the deflectable member allows a second medical device to move between the common lumen region and the second lumen.
