摘要： A diagnostic device for determining the amount of change required in a coronary sinus to reduce valve regurgitation. The device includes a distal tube having a distal anchor at a distal end portion of the distal tube, a proximal tube having a proximal anchor at a distal end portion of the proximal tube, and an adjustor to move the distal tube relative to the proximal tube. The proximal tube and the distal tube together form a telescoping elongate body adapted to fit within the coronary sinus, and the device includes a scale to measure the movement of the distal anchor relative to the proximal anchor.

摘要： A system and method is provided for treating a mitral valve. The method preferably includes advancing a guide catheter to an ostium of the coronary sinus and advancing a delivery catheter containing a medical implant through the guide catheter and into the coronary sinus. The delivery catheter has an inner member on which the medical implant is held and an outer sheath which is retractable for deploying and releasing the medical implant. In one embodiment, the medical implant has proximal and distal anchors and a bridge containing resorbable material. The inner member may have a flexible sleeve for gripping and holding a portion of the outer sheath, thereby providing a releasable attachment mechanism. In another embodiment, the inner member may include an inflatable balloon having a tapered distal region which extends from the outer sheath for providing an atraumatic tip. The inflatable balloon may also be used to expand the medical implant and to grip the outer sheath.

摘要： A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment.

摘要： A system for treating a bifurcation includes first and second delivery catheters. The first catheter has a first shaft, a first expandable member adjacent the distal end of the first shaft, an auxiliary expandable member disposed under the first expandable member, and a first radially expandable stent disposed over both the first expandable member and the auxiliary expandable member. The second delivery catheter has a second shaft, and a second expandable member adjacent the distal end of the second shaft. A portion of the second catheter is disposed under a portion of the first stent, and a portion of the second delivery catheter passes through a side hole in the first stent. The first stent is crimped over the first and second catheters such that the first stent remains attached to the first and the second catheters during advancement of the catheters through a blood vessel.

摘要： Methods for crimping a stent on an expandable member of a delivery catheter, and devices and methods for treating a bifurcation are disclosed. A method for crimping includes positioning a stent having a first portion and a second portion over the expandable member, and non-uniformly crimping the stent to the expandable member. The method can include routing an elongate shaft under the second portion of the stent and through the side hole so as to be routed external to the first portion. The stent second portion can be crimped so that the elongate shaft can be slidably disposed relative to the stent second portion prior to deployment of the stent.
