For example, an implant device can include an anchoring structure to anchor the implant device to a blood vessel, heart valve, or other anatomy. The anchoring structure can be coupled to an elastic tube that is configured to expand. The elastic tube can include a prosthetic valve to permit fluid to flow through the implant device. ## Claims ### Claim 1 An implant device comprising: a first elastic tube including a first end portion and a second end portion, the first elastic tube adapted to extend from the first end portion into a heart chamber; a first anchoring structure associated with the first end portion and dimensioned to be anchored to a native heart valve associated with the heart chamber; and a first prosthetic valve coupled to the second end portion, the first prosthetic valve adapted to be disposed within the heart chamber. ### Claim 2 (depends on 1) The implant device of claim 1, further comprising: a frame including a cylindrical form, the frame being disposed within the first elastic tube and dimensioned to prevent the first elastic tube from radially compressing. ### Claim 3 (depends on 2) The implant device of claim 2, further comprising: a second elastic tube including a first end portion and a second end portion, the first end portion of the second elastic tube being coupled to the first end portion of the first elastic tube. ### Claim 4 (depends on 3) The implant device of claim 3, further comprising: a second anchoring structure associated with the second end portion of the second elastic tube and dimensioned to anchor the second elastic tube to a blood vessel. ### Claim 5 (depends on 1) The implant device of claim 1, further comprising: a second prosthetic valve coupled to the first end portion of the first elastic tube. ### Claim 6 (depends on 5) The implant device of claim 5, wherein the first prosthetic valve includes a first blood flow characteristic that is based at least in part on a second blood flow characteristic of the second prosthetic valve. ### Claim 7 (depends on 1) The implant device of claim 1, wherein the first prosthetic valve includes a second anchoring structure configured to anchor the first prosthetic valve to tissue within the heart chamber. ### Claim 8 (depends on 1) The implant device of claim 1, further comprising: a valve docking station coupled to the first anchoring structure and adapted to receive a second prosthetic valve. ### Claim 9 An implant device comprising: a first anchoring feature adapted to be anchored to a heart valve; a first compliant tube coupled to the first anchoring feature at a first end portion of the first compliant tube; and a prosthetic valve coupled to a second end portion of the first compliant tube, the prosthetic valve adapted to be disposed within a heart chamber. ### Claim 10 (depends on 9) The implant device of claim 9, further comprising: a frame disposed within the first compliant tube and dimensioned to maintain a minimum diameter for the first compliant tube when the first compliant tube radially compresses. ### Claim 11 (depends on 9) The implant device of claim 9, further comprising: a second compliant tube including a first end portion and a second end portion, the first end portion of the second compliant tube being coupled to the prosthetic valve; and a second anchoring feature associated with the second end portion of the second compliant tube and dimensioned to anchor the second compliant tube to a blood vessel. ### Claim 12 (depends on 9) The implant device of claim 9, wherein the prosthetic valve includes a second anchoring feature configured to anchor the prosthetic valve to tissue within the heart chamber. ### Claim 13 (depends on 9) The implant device of claim 9, further comprising: a valve docking station coupled to the first anchoring feature and adapted to receive another prosthetic valve. ### Claim 14 (depends on 9) The implant device of claim 9, wherein the heart valve is an aortic valve. ### Claim 15 An implant device comprising: a first anchoring structure adapted to anchor to a heart chamber; a first prosthetic valve coupled to the first anchoring structure; a second anchoring structure adapted to anchor to a native heart valve; and an elastic tube coupled between the first anchoring structure and the second anchoring structure to provide a channel to an output blood vessel associated with the native heart valve. ### Claim 16 (depends on 15) The implant device of claim 15, wherein the first anchoring structure includes an inner frame structure that has a smaller diameter than an outer diameter of the first anchoring structure, the elastic tube being coupled to the inner frame structure. ### Claim 17 (depends on 15) The implant device of claim 15, further comprising: a valve docking station associated with the second anchoring structure and adapted to receive a second prosthetic valve. ### Claim 18 (depends on 15) The implant device of claim 15, further comprising: a second prosthetic valve associated with the second anchoring structure. ### Claim 19 (depends on 18) The implant device of claim 18, wherein the first prosthetic valve includes a first blood flow characteristic that is based at least in part on a second blood flow characteristic of the second prosthetic valve. ### Claim 20 (depends on 15) The implant device of claim 15, wherein at least one of the first anchoring structure or the second anchoring structure includes an expandable frame.
