A replacement heart valve implant may include a braided anchor member configured to actuate between a delivery configuration and a deployed configuration formed from a plurality of filaments, a circumferential seal member disposed about a distal portion of the anchor member and including a reinforcing band disposed at a distal end thereof, and a plurality of valve leaflets connected to the anchor member. The reinforcing band is secured to the anchor member adjacent a distal end of the anchor member by a plurality of lashings each attached to two individual filaments. The plurality of filaments defines a body section, a proximal crown section, and a distal crown section, wherein the proximal crown section includes a first plurality of end loops and a second plurality of end loops, wherein a proximalmost extent of the first plurality of end loops and the second plurality of end loops varies.

1. A replacement heart valve implant, comprising: a braided anchor member configured to actuate between an elongated delivery configuration and an expanded deployed configuration, the braided anchor member formed from a plurality of filaments;a circumferential seal member disposed about a distal portion of the braided anchor member, the circumferential seal member including a reinforcing band disposed at a distal end thereof; anda plurality of valve leaflets connected to the braided anchor member;wherein the reinforcing band is secured to the braided anchor member adjacent a distal end of the braided anchor member by a plurality of lashings, wherein each lashing is attached to two individual filaments of the plurality of filaments. 2. The replacement heart valve implant of claim 1, wherein the two individual filaments are crossing each other where each lashing is attached thereto. 3. The replacement heart valve implant of claim 1, wherein the two individual filaments are immediately adjacent each other where each lashing is attached thereto. 4. The replacement heart valve implant of claim 1, wherein at least a portion of the braided anchor member extends distally of the plurality of lashings. 5. The replacement heart valve implant of claim 4, wherein at least a portion of the braided anchor member extends distally of all of the plurality of lashings. 6. The replacement heart valve implant of claim 4, wherein at least a portion of each of the two individual filaments extends distally of each lashing attached thereto. 7. The replacement heart valve implant of claim 1, wherein each lashing comprises more than one suture member. 8. The replacement heart valve implant of claim 1, wherein the reinforcing band includes a fabric strip. 9. The replacement heart valve implant of claim 1, wherein each of the plurality of valve leaflets is secured directly to the reinforcing band. 10. A replacement heart valve implant, comprising: a braided anchor member configured to actuate between an elongated delivery configuration and an expanded deployed configuration, the braided anchor member formed from a plurality of filaments defining a body section, a proximal crown section, and a distal crown section;a circumferential seal member disposed about a distal portion of the braided anchor member, the circumferential seal member including a reinforcing band disposed at a distal end thereof; anda plurality of valve leaflets connected to the braided anchor member;wherein the proximal crown section includes a first plurality of end loops and a second plurality of end loops;wherein a proximalmost extent of the first plurality of end loops and the second plurality of end loops varies around a circumference of the braided anchor member. 11. The replacement heart valve implant of claim 10, wherein when the braided anchor member is in the deployed configuration the first plurality of end loops extends proximally to a first proximal extent and the second plurality of end loops extends proximally to a second proximal extent distal of the first proximal extent. 12. The replacement heart valve implant of claim 10, wherein the braided anchor member includes a plurality of buckle members fixedly attached thereto, the plurality of buckle members being configured to lock the braided anchor member in the deployed configuration. 13. The replacement heart valve implant of claim 12, wherein each of the plurality of buckle members is positioned circumferentially between adjacent end loops from the first plurality of end loops. 14. The replacement heart valve implant of claim 12, wherein each of the plurality of buckle members is positioned circumferentially over one of the second plurality of end loops. 15. The replacement heart valve implant of claim 12, wherein two of the first plurality of end loops and two of the second plurality of end loops is disposed circumferentially between adjacent buckle members. 16. The replacement heart valve implant of claim 10, wherein when the braided anchor member is in the elongated delivery configuration the first plurality of end loops extends farther proximally than the second plurality of end loops. 17. The replacement heart valve implant of claim 10, wherein the distal crown section includes a third plurality of end loops and a fourth plurality of end loops; wherein a distalmost extent of the third plurality of end loops and the fourth plurality of end loops varies around a circumference of the braided anchor member. 18. The replacement heart valve implant of claim 17, wherein when the braided anchor member is in the deployed configuration the third plurality of end loops extends distally to a first distal extent and the fourth plurality of end loops extends distally to a second distal extent proximal of the first distal extent. 19. The replacement heart valve implant of claim 17, wherein when the braided anchor member is in the elongated delivery configuration the third plurality of end loops extends farther distally than the fourth plurality of end loops. 20. The replacement heart valve implant of claim 10, wherein the braided anchor member is formed from a metallic material.
