Abstract:
1. A delivery catheter for implanting a medical device, comprising: a handle; a catheter shaft coupled to the handle; a first tether disposed within the catheter shaft and extending distally beyond the catheter shaft, the first tether including a first locking feature positioned near a distal portion of the first tether; a second tether disposed within the catheter shaft and extending distally beyond the catheter shaft, the second tether including a second locking feature positioned near a distal portion of the second tether; a tether adjustment feature coupled to the first tether, the tether adjustment feature configured to adjust a length of the first tether extending distally beyond the catheter shaft to switch the delivery catheter between an aligned configuration and a non-aligned configuration, wherein the first locking feature is at least partially longitudinally aligned with the second locking feature in the aligned configuration, wherein the first locking feature is not longitudinally aligned with the second locking feature in the un-aligned configuration; further comprising a tether shuttle coupled to the handle, wherein: the tether adjustment feature comprises a tether adjustment key, the first tether comprises a tether key disposed within the tether shuttle, and the tether adjustment feature is configured to mate with and engage the tether key to move the tether key distally or proximally within the tether shuttle to adjust the length of the first tether extending distally beyond the catheter to thereby switch the first and second locking features of the first and second tethers between longitudinally aligned and non-aligned positions.
