VALVE TREATMENT DEVICES, SYSTEMS, AND METHODS

摘要

Medical device systems, methods and devices are provided for treating a valve in a heart to minimize valve regurgitation. The medical device system includes an RF energy source, a handle, a treatment catheter, and a treatment device. The handle is operatively coupled to the RF energy source and coupled to the treatment catheter. The treatment device includes exposed electrode portions of one or more electrodes operatively coupled to the RF energy source and configured to contact tissue of a valve annulus. Further, one or more of the exposed electrode portions include a marker associated therewith. With this arrangement, a physician may view the one or more markers and selectively activate particular exposed electrode portions with RF energy to selectively treat a portion of the valve annulus.

1. A medical device system for treating a valve in a heart to minimize valve regurgitation, the medical device system comprising:
an RF energy source; a handle operatively coupled to the RF energy source; a treatment catheter coupled to the handle, the treatment catheter extending between a proximal end and a distal end and including a lumen defined along a length of the treatment catheter; and a treatment device disposed at the distal end of the treatment catheter, the treatment device moveable between a constricted position and an expanded position, the treatment device including multiple strands extending in a woven configuration and, in the expanded position, configured to be conformable to a valve annulus, the treatment device including a lower periphery with exposed electrode portions of one or more electrodes, one or more of the exposed electrode portions including markers associated therewith and the exposed electrode portions configured to be selectively activated to heat a selective portion of the valve annulus.
