Prosthetic valve docking device having a guard member

A docking device for securing a prosthetic implant at a native valve, the docking device comprising:

• a coil defining a longitudinal axis extending through a lumen of the coil from an inflow side to an outflow side and comprising a plurality of helical turns when deployed at the native valve, wherein at least one of the helical turns comprises a first coil region configured to be disposed on the inflow side of a native annulus and to stabilize the coil relative to the native annulus wherein a proximal end portion of the first coil region is lifted relative to a plane defined by the first coil region and normal to the longitudinal axis and wherein a proximal end of the first coil region is above the plane defined by the first coil region by less than 12 mm and at least one of the helical turns comprises a second coil region extending from a distal end of the first coil region and configured to be disposed on the outflow side of a native annulus and to receive a prosthetic valve;
• and
• a guard member coupled at least partially to the outflow side of the first coil region wherein the guard member is movable between a radially compressed state and a radially expanded state.

A coil for a docking device for securing a prosthetic valve, the coil comprising:

• a core comprising a plurality of helical turns and defining a longitudinal axis extending through a lumen of the plurality of helical turns from an inflow side to an outflow side when deployed at a native valve, wherein at least one of the helical turns comprises a first region configured to be disposed on the inflow side of a native annulus and to stabilize the coil relative to the native annulus and at least one of the helical turns comprises a second region extending from a distal end of the first region and configured to be disposed on the outflow side of a native annulus and to receive a prosthetic valve;
• and
• a cover encompassing at least a portion of the core and comprising a first outer diameter and a second outer diameter which is larger than the first outer diameter, wherein the second region comprises the second outer dim.
