Delivery and occlusion devices for paravalvular leak

A paravalvular occlusion apparatus, comprising:

• a catheter comprising:
• a main body having a proximal end and a distal end;
• a visualization element disposed in the distal end of the main body;
• a working channel extending from the distal end of the main body;
• and
• an elongate shaft extendable from the working channel;
• and
• an occlusion device coupled to the elongate shaft, the occlusion device comprising:
• a leading end including a first section;
• a trailing end opposite the leading end, the trailing end including a second section, wherein the first section and the second section are operable to be positioned along a perimeter of an artificial valve in an area of a paravalvular leak;
• and
• a connector element extending between the first and second sections.

A method for delivering an occlusion device to a paravalvular leak, the method comprising:

• advancing a catheter in a body of patient to a paravalvular leak, the catheter comprising:
• a main body having a proximal end and a distal end;
• a visualization element disposed in the distal end of the main body;
• a working channel extending from the distal end of the main body;
• and
• an elongate shaft extendable from the working channel;
• and
• delivering an occlusion device from the working channel of the catheter, the occlusion device comprising:
• a leading end including a first section;
• and
• a trailing end opposite the leading end, the trailing end including a second section connected to the first section by a connector element, wherein the first section and the second section are operable to be positioned along a perimeter of a prosthetic valve.
