1. A delivery device for a stented heart valve comprising:
- a handle;
an elongate shaft extending from a distal end of the handle; and
a conical housing having a proximal end coupled to the elongate shaft and an open distal end, the conical housing having a conical lumen therein with a first internal diameter adjacent to the proximal end of the conical housing and a larger second internal diameter adjacent to the open distal end of the conical housing.

24. A method of loading a stented heart valve into a delivery device comprising:
-
receiving a delivery device, the delivery device including a handle on a proximal end, a housing on a distal end, and a shaft extending therebetween; crimping a stented heart valve with a crimping tool, the stented heart valve including a radially compressible support stent, a replacement valve, and a control suture; pushing the crimped stented heart valve into the housing of the delivery device; pulling the control suture through the shaft and the handle of the delivery device; and engaging the control suture with an engagement mechanism operably coupled to the handle of the delivery device to apply tension to the control suture such that the crimped stented heart valve is retained within the housing. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of delivering a stented heart valve to an implantation site comprising:
-
receiving a delivery device including a conical housing, the conical housing having a conical lumen therein with a first internal diameter adjacent to a proximal end of the conical housing and a larger second internal diameter adjacent to a distal end of the conical housing; loading a crimped stented heart valve into the conical housing such that an inflow end of the stented heart valve extends outside of the housing past the distal end; positioning the conical housing at an implantation site; allowing the inflow end of the stented heart valve to expand within the implantation site; and manipulating the delivery device to expose additional portions of the stented heart valve to allow for expansion within the implantation site. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48)
