Abstract
A catheter based medical system and medical procedure for reducing cardiac valve regurgitation are disclosed. The system comprises a resilient curvilinear shaped annuloplasty implant for reducing the size of a dilated annulus of said valve for reducing said regurgitation having resilient anchoring elements, and a delivery device for said annuloplasty implant having a distal curvilinear shaped portion that is hollow to mount said annuloplasty implant and has an annular opening arranged to be in apposition against an annulus of said cardiac valve. A plurality of suction units allows for a atrial approach and symmetric implantation of said implant.
Claims20
A catheter based medical system, including a retractable delivery device for delivery of a medical implant, such as an annuloplasty implant for reducing cardiac valve regurgitation, having a distal portion for releasably holding said implant, and for apposition against a target tissue for said implant, such as an annulus of a cardiac valve, wherein said distal portion comprises a plurality of suction units for providing and/or determining a desired apposition of said distal portion at said target tissue prior to releasing said medical implant to said tissue and retracting said delivery device.
A medical procedure for reducing cardiac valve regurgitation including the steps of:
- measuring the geometry of a dilated cardiac valve of a patient including the shape and size of a dilated annulus thereof;
- determining the downsized shape and size of said annulus;
- selecting a resilient annuloplasty implant having in a tissue engaging conformation a shape and size to be arranged at said downsized annulus based on said determined downsized shape and size of said annulus;
- introducing said annuloplasty implant in a delivery device in a compressed state via a catheter to said cardiac valve;
- releasing an aggregate of a distal portion of said delivery device and said annuloplasty implant in a stretched state in said delivery device from said catheter such that implant assumes an expanded shape;
- positioning said aggregate at said annulus;
- fixation said distal portion to said annulus, e.g. by activating suction of suction units;
- providing and/or verifying a desired apposition of said distal portion at said annulus prior to releasing said implant;
- releasing and anchoring said annuloplasty implant into said annulus;
- reducing the size of said delivery device and/or annuloplasty implant for reshaping said annulus to said downsized shape;
- optionally determining a reduction of said cardiac valve regurgitation, and removing said delivery device and catheter if the reduction is satisfactory, or removing said annuloplasty implant together with said delivery device when said reduction is determined as not being satisfactory.
