Abstract
A delivery system for delivering an implantable stented device to a lumen of a patient, the delivery system including an elongated body having a proximal end and a distal end, a driver mechanism positioned at the proximal end of the elongated body, an elongated threaded rod located axially distal to the driver mechanism, and a sheath including an elongated tubular portion having a hollow interior portion with a first diameter that is sized for compression and retention of the implantable stented device in a compressed configuration for delivery to a body lumen.

21. A delivery system for delivering an implantable stented device to a lumen of a patient, the delivery system comprising:
-
an elongated body comprising a proximal end and a distal end comprising a tip; a plurality of stent engagement elements, wherein each stent engagement element includes an elongated wire and a tip portion for engagement with the implantable stented device; a plurality of sleeves, wherein each sleeve surrounds a respective stent engagement element, wherein the plurality of sleeves and stent engagement elements include a first position wherein each sleeve surrounds a respective one of the tip portions and a portion of the implantable stented device and a second position wherein each sleeve is spaced proximally of the respective tip portion; a sheath comprising an elongated tubular portion having a hollow interior portion with a first diameter that is sized for compression and retention of the implantable stented device in a compressed configuration for delivery to a body lumen, wherein with the stent engagement elements and the sleeves in the second position, the sheath is configured such that advancement of the sheath distally causes the tip portions to move towards a central longitudinal axis of the delivery system to disengage the tip portions from the implantable stented device. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A delivery system for delivering an implantable stented device to a lumen of a patient, the delivery system comprising:
-
an elongated body comprising a proximal end and a distal end comprising a tip; a sheath comprising an elongated tubular portion having a hollow interior portion that is sized for compression and retention of the implantable stented device in a compressed configuration for delivery to a body lumen; a plurality of stent engagement mechanisms, each of the plurality of stent engagement mechanisms being axially translatable from a distal end of the sheath and each of which includes a first portion and a second portion engageable with a proximal end of a stented device; and a plurality of sleeves surrounding the stent engagement mechanisms; wherein the plurality of sleeves are movable between a stent engagement position wherein each sleeve surrounds the second portion of a respective one of the stent engagement mechanisms and a portion of the implantable stent device, and a stent deployment position wherein the second portion of each stent engagement mechanism is spaced axially distal of each respective sleeve, wherein with the stent engagement mechanisms in the stent deployment position, movement of the sheath distally causes the stent engagement mechanisms to move toward a central axis of the elongated body such that the second portions of the stent engagement mechanisms disengage from the implantable stented device. - View Dependent Claims (30, 31)
