A delivery catheter for a stent. The delivery catheter may have a distal end and a proximal end. The distal end includes a stent attachment region adapted to receive a stent. The stent may be of the self-expanding type. The catheter further includes a handle at its proximal end and at least one sheath which may at least partially circumferentially cover the stent such as to retain it in a collapsed configuration. The sheath is coupled at its proximal end to an actuator located on the handle portion. The catheter further includes at least one radio-opaque indicator for indicating a rotational orientation of the delivery catheter and/or the stent when observed using medical imaging during implantation of the stent.

Catheter delivery system for stent valve

Apparatus () for compressing a transcatheter cardiac stent-valve () comprises: a first compressor stage () including a hollow channel () with a tapered interior surface configured for compressing a stent-valve in response to longitudinal advancement of the stent-valve within the channel; and a second compressor stage () comprising a crimper for compressing a portion of the stent-valve without longitudinal advancement.

Method and apparatus for compressing/loading stent-valves

Example medical device delivery systems are disclosed. An example delivery system for an implantable medical device includes an outer shaft having a distal end region, a proximal end region and a lumen extending therebetween. The delivery system also includes a handle coupled to the proximal end region of the outer shaft, wherein the handle includes a first actuator, a carriage and a housing. The delivery system also includes a selector coupled to the handle and a resistance member disposed along a portion of the selector. Further, the selector is configured to shift between a first configuration and a deployment configuration. Additionally, the carriage is free from the resistance member in the first configuration and the resistance member contacts the carriage in the deployment configuration.

Medical device delivery system including a resistance member

A delivery apparatus for delivering a stent-valve for implantation within the body, the delivery apparatus configured for introduction into the body through an arterial introducer of a type having a stem insertable into the body and a mouth section that remains outside the body, the mouth section including a haemostasis valve, and wherein the delivery apparatus comprises: a first constraining sheath at a stent-valve accommodation region of the apparatus at a distal end of the apparatus, and configured for constraining at least a portion of a stent-valve at the accommodation region in a radially collapsed configuration; a delivery introducer captive on the delivery apparatus, and slidable between a first position surrounding at least a portion of the stent-valve accommodation region, and a second position in which the delivery introducer slides proximally of the stent-valve accommodation region; wherein the delivery introducer is insertable at least partly into the mouth of a said arterial introducer, the delivery introducer configured for introducing the stent-accommodation region through the haemostasis valve.
