摘要： An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. In some implementations, the implantable device or implant, or one or more portions thereof, can be configured to expand and/or contract. For example, the implantable device or implant can narrow during delivery and expand on implantation on the native heart valve.

摘要： Catheterization methods and apparatuses allow sensing of pressures inside the heart and for removing air from catheters. A delivery system can use the same components that are used to deliver a valve repair or replacement device to measure the pressure in the atrium or other heart chamber. A pressure sensor can be included in one of the catheters of the delivery system or pressure can be sensed through the same port that is used to flush a catheter. The delivery system can be inserted into the heart, delivering the valve repair or replacement device to the native valve, such as the mitral valve, the tricuspid valve, the aortic valve, or the pulmonary valve.

摘要： A method and system for implanting and repositioning an implantable device for a native valve of a patient's heart includes a delivery catheter, a collar, a coupler, and an actuation element. The actuation element extends through the delivery catheter and attaches to the device to open the device. The collar is connected to the device and the coupler is connected to the delivery catheter. The collar and coupler are tied together via one or more coupling tethers which can be used to reengage the device after an initial deployment.
