A transluminal delivery system and a method of assembling. The system includes a cylindrical, inner-catheter component and a retractable sheath surrounding the component and defining a space between the component and the sheath to receive a self-expanding luminal prosthesis between the component and the sheath. The inner-catheter component may include at least one sleeve having fibers, at least one connected sleeve portion connected to the inner catheter, and at least one unconnected sleeve portion slidably engaging the inner catheter such that when the sheath retracts, the unconnected portion expands and sleeve fibers engage the prosthesis's luminal surface, wherein the engagement opposes proximal stent movement.

Transluminal delivery system

A method of moving a stent device into an outer sheath of a stent device delivery system is disclosed. The stent device is crimped into a collapsed configuration onto the loading mandrel. The loading mandrel is pushed toward the outer sheath as the engaging surfaces resist relative longitudinal movement between the stent device and the loading mandrel to move the stent device into the outer sheath. Upon entering the outer sheath, the stent device expands radially until radially constrained by the outer sheath.

Stent device, a crimping head, and an outer sheath of a stent device delivery system

A method of moving a stent device into an outer sheath of a stent device delivery system is disclosed. The stent device () is crimped into a collapsed configuration onto the loading mandrel (). The loading mandrel is pushed toward the outer sheath as the engaging surfaces () resist relative longitudinal movement between the stent device and the loading mandrel to move the stent device into the outer sheath (). Upon entering the outer sheath, the stent device expands radially until radially constrained by the outer sheath.

Method of transferring a stent device from a crimping head to an outer sheath of a stent device delivery system

A method of moving a stent device into an outer sheath of a stent: device delivery system is disclosed. The stent device () is Crimped into a collapsed configuration onto the loading mandrel (). The loading mandrel is pushed towards the outer sheath as the engaging surfaces () resist relative longitudinal movement between the stent device and the loading mandrel to move the stent device into the outer sheath (). Upon entering the outer sheath, the stent device expands radially until radially constrained by the outer sheath.

There is disclosed herein a transluminal delivery system for a self-expanding luminal prosthesis, the system comprising an inner catheter component () and a retractable sheath () to surround the component thereby to define an annular space to receive the prosthesis (), the component exhibiting an anti-sliding component, for abutting a luminal surface portion of the prosthesis () to restrain the prosthesis from sliding with the sheath (), and relative to the inner catheter (), while the sheath retracts relative to the prosthesis to release the prosthesis progressively into the target bodily lumen characterized in that the anti-sliding component is or includes at least one sleeve () having a length direction parallel to the longitudinal axis of the annular space and having at least one bound portion () of its length that is not free to slide on the inner catheter, and at least one unbound portion of its length with a capability to slide axially on the inner catheter () and thereby to exhibit a radial swelling capability, to deliver an increase in the radial thickness of the sleeve () while the sheath retracts. Associated methods are also disclosed.

A delivery device () for delivering a stent device () in a reduced profiled delivery configuration is provided. A distal region () of the stent device is axially anchored to an inner catheter () by annular rings () about the inner catheter. A remaining portion () of the stent device is spaced radially from the inner catheter. A proximal stop () is spaced axially from a proximal end of the stent device. The stent device is maintained in the reduced profile delivery configuration by a retractable outer sheath ().

Delivery device for delivering a stent device

A device for trans-luminal delivery of a self-expanding stent or other surgical device and which is designed for rapid exchange over a guidewire has a guidewire lumen that adjacent its proximal exit port lies side -by-side with the line of the shaft of the device. A sleeve which surrounds and confines the stent has a proximal end that is shaped around the guidewire exit port to show in profile a shape reminiscent of the nose of a dolphin. In preferred embodiments, the sleeve also has a tapered distal tip that is withdrawn proximally over the length of the stent to release it, progressively, from its distal end. The configuration delivers simplicity of design, enhanced performance and reliability in use.
