摘要： An apparatus for automatically retroperfusing a coronary vein includes an intraluminal cannula having a main body portion extending between a proximal end portion and a distal end portion. The proximal end portion is for connecting to an artery outside of the pericardium to automatically supply oxygenated blood from the artery for retroperfusion. The main body portion and the distal end portion are insertable through a vein that is fluidly connected with the coronary vein and into the coronary vein. An expandable stent is attached to the distal end portion for expanding radially into engagement with the interior wall of the coronary vein to secure the distal end portion at a desired location within the coronary vein. Occluding structure for at least partially occluding the coronary vein is provided at the distal end to decrease the back-flow of blood into the right atrium during retroperfusion. The cannula includes passages that allow a limited amount of blood to bypass the occluding structure.

摘要： An annuloplasty ring for repairing a cardiac valve includes an expandable support member having oppositely disposed proximal and distal end portions and a main body portion between the end portions. The proximal end portion of the support member includes a plurality of wing members that extend from the main body portion. Each of the wing members includes at least one hook member for embedding into a cardiac wall and the valve annulus to secure the annuloplasty ring in the valve annulus. The annuloplasty ring may be expanded into full contact engagement with the annulus of the cardiac valve by an inflatable balloon. Methods for repairing a cardiac valve using the annuloplasty ring are also provided.

摘要： An apparatus for modifying the annulus of a cardiac valve to reduce regurgitation of blood flow through the cardiac valve includes a first annuloplasty ring having a first diameter and being disposed about a first aspect of the annulus of the cardiac valve. The apparatus also includes an elongate flexible body having proximal and distal end portions and being insertable into the first annuloplasty ring. The elongate flexible body has an adjustable mechanism for selectively adjusting the elongate flexible body from a first relaxed configuration to a second tensioned configuration. The first annuloplasty ring is adaptable to obtain a second smaller diameter and to cause the annulus of the cardiac valve to be modified and reduce regurgitation of blood flow through the cardiac valve when the elongate flexible body obtains the second tensioned configuration.

摘要： An apparatus for fluidly isolating a portion of a blood vessel wall from bloodflow at an anastomosis site within a blood vessel is described. An insertion catheter has longitudinally spaced proximal and distal catheter ends and an operative lumen extending therebetween, and is configured for insertion into the blood vessel at an insertion location spaced apart from the anastomosis site. An isolation device is attached to the distal catheter end, and includes a concave working surface bounded by an isolation rim and a bloodflow surface opposite the working surface. The isolation rim is configured to contact at least a portion of the blood vessel longitudinally aligned with, and radially spaced from, the anastomosis site. The bloodflow surface is in contact with bloodflow past the anastomosis site within the blood vessel when the isolation device engages the blood vessel wall. A retention means is attached to the isolation device and in fluid communication with the operative lumen. The retention means is configured to exert force on the blood vessel wall to at least partially engage the blood vessel wall with the isolation device. A method of fluidly isolating a portion of a blood vessel wall from bloodflow at an anastomosis site within a blood vessel is also provided.

摘要： A method is provided for implanting a valve having at least one valve leaflet within the cardiovascular system of a subject. One step of the method includes preparing a substantially dehydrated bioprosthetic valve and then providing an expandable support member having oppositely disposed first and second ends and a main body portion extending between the ends. Next, the substantially dehydrated bioprosthetic valve is attached to the expandable support member so that the substantially dehydrated bioprosthetic valve is operably secured within the main body portion of the expandable support member. The expandable support member is then crimped into a compressed configuration and placed at a desired location within the cardiovascular system of the subject. Either before or after placement at the desired location, fluid or blood re-hydrates the substantially dehydrated bioprosthetic valve.

摘要： An apparatus is provided for replacing a native cardiac valve. The native cardiac valve has at least one leaflet and is surrounded by a native cardiac valve annulus having superior and inferior aspects. The apparatus comprises a barbell-shaped, expandable anchoring member including first, second, and main body portions extending between the end portions. The main body portion includes a channel defined by inner and outer surfaces. Each of the first and second end portions has a diameter greater than the diameter of the main body portion. The first and second end portions are sized to respectively contact the superior and inferior aspects of the native cardiac valve annulus when the expandable anchoring member is in an expanded configuration. The apparatus also includes an expandable support member operably disposed within the main body portion of the expandable anchoring member, and a prosthetic cardiac valve secured within the expandable support member.
