    摘要: Methods and devices for successively advancing a plurality of catheters over a guide element to a body tissue are described. In some of the methods, the guide element may be attached to the body tissue, which may be accessible minimally invasively. In certain variations, the guide element may not be detached from the body tissue after the catheters have been advanced over the guide element. The methods may further comprise deploying at least one implant from at least one of the plurality of catheters. In some variations, a method may comprise advancing a first delivery catheter to a first region of a body tissue, deploying a first anchor from the first delivery catheter, where the first anchor is attached to a guide element, proximally withdrawing the first delivery catheter, advancing a second delivery catheter over the guide element, and deploying a second anchor from the second delivery catheter.

    摘要: Described herein are devices and methods for guide catheters having one or more regions of increased flexibility. A flexibility region comprises one tubular segment of the guide catheter with a non-linear longitudinal seam between two non-concentric layers of material having different durometers. A non-linear seam, such as a zig-zag or sinusoidal configuration, permits controlled compression of lower durometer material between portions of higher durometer material.

    摘要: The present disclosure describes an angioplasty balloon catheter having a retractable sheath and a flexible tip attached to the distal end of the sheath. The flexible tip is made of an elastomeric plastic that is capable of returning to its original shape after being expanded multiple times. The tip allows for the sheath to be retractable and the balloon inflated multiple times to treat or expand different locations within the vessel. Because the tip returns to its original shape each time, the tip is less likely to damage the vessel wall when the sheath is repositioned in the vessel, and also is easier to retract through a guide-catheter.
