A prosthetic valve delivery assembly (500; 600), comprising: a prosthetic valve comprising a self-expandable stent having a plurality of apices (302, 306) spaced circumferentially around a first end portion of the stent, wherein each apex (302, 306) has an aperture (304; 308); an elongate shaft (502; 606) located proximal to the prosthetic valve; a suture-retention member (510; 626) located distal to the shaft (502; 606), the suture-retention member (510; 626) comprising a proximal portion (512; 638) and a distal portion (516; 636) spaced from the proximal portion (512; 638), the proximal portion (512; 638) being coupled to the shaft; at least one slidable release member (520; 628) extending through the proximal portion (512; 638) and the distal portion (516; 636) of the suture-retention member (510; 626); a plurality of suture loops extending from the proximal portion (512; 638) of the suture-retention member (510; 626), through the apertures (304; 308) in the apices (302, 306) of the stent, and around the release member (520; 628) at a location between the proximal and distal portions (512, 516; 638, 636) of suture-retention member (510; 626), wherein each apex (302, 306) has at least one of the suture loops extending through the aperture (304; 308) of the apex (302, 306); and an outer sheath (504; 612) which can be advanced over the prosthetic valve to retain the prosthetic valve in a radially compressed state and retracted relative to the prosthetic valve to permit radial expansion of the prosthetic valve, while the stent remains connected to the suture-retention member (510; 626) via the suture loops; wherein after the entirety of the prosthetic valve is deployed from the sheath (504; 612), the sheath (504; 612) can be advanced distally back over the prosthetic valve to cause the prosthetic valve to radially collapse as it is recaptured by the sheath (504; 612). a prosthetic valve comprising a self-expandable stent having a plurality of apices (302, 306) spaced circumferentially around a first end portion of the stent, wherein each apex (302, 306) has an aperture (304; 308); an elongate shaft (502; 606) located proximal to the prosthetic valve; a suture-retention member (510; 626) located distal to the shaft (502; 606), the suture-retention member (510; 626) comprising a proximal portion (512; 638) and a distal portion (516; 636) spaced from the proximal portion (512; 638), the proximal portion (512; 638) being coupled to the shaft; at least one slidable release member (520; 628) extending through the proximal portion (512; 638) and the distal portion (516; 636) of the suture-retention member (510; 626); a plurality of suture loops extending from the proximal portion (512; 638) of the suture-retention member (510; 626), through the apertures (304; 308) in the apices (302, 306) of the stent, and around the release member (520; 628) at a location between the proximal and distal portions (512, 516; 638, 636) of suture-retention member (510; 626), wherein each apex (302, 306) has at least one of the suture loops extending through the aperture (304; 308) of the apex (302, 306); and an outer sheath (504; 612) which can be advanced over the prosthetic valve to retain the prosthetic valve in a radially compressed state and retracted relative to the prosthetic valve to permit radial expansion of the prosthetic valve, while the stent remains connected to the suture-retention member (510; 626) via the suture loops; wherein after the entirety of the prosthetic valve is deployed from the sheath (504; 612), the sheath (504; 612) can be advanced distally back over the prosthetic valve to cause the prosthetic valve to radially collapse as it is recaptured by the sheath (504; 612).
