positioning a multi-aperture catheter circumferentially along myocardium located generally at or near papillary muscles, the multi-aperture catheter comprising a lumen at least partially therethrough and a plurality of apertures along a distal portion of the catheter, wherein the plurality of apertures are defined by a plurality of releasable retaining structures;
advancing a device comprising at least one anchor coupled to a tether at least partially through the lumen;
temporarily securing the distal portion of the multi-aperture catheter to the myocardium using the device, wherein the tether is retained within the lumen;
releasing the multi-aperture catheter from the myocardium by releasing the tether from the lumen, wherein the at least one anchor and the tether remain secured to the myocardium at or near the papillary muscles; and
removing the multi-aperture catheter from the heart.
