Abstract
The present invention describes a device for delivering a stent to a bodily stricture. The delivery device advantageously includes a funnel shaped distal end configured to facilitate compressing the stent onto the delivery device. The funnel may further include a tear away strip suitable for separating the funnel from the delivery device.
Claims10
A stent delivery device comprising:
- an elongate member having a distal portion;
- a tube slideably mounted about the distal portion of the member, the tube having a distal end;
- and
- a stent loading funnel mounted on the distal end of the tube and comprising a peel away means for removing the stent loading funnel after the stent has been mounted on the delivery device.

An assembly for delivering an endoprosthesis to a bodily stricture comprising:
- an exterior tube;
- and
- an interior member slideably mounted within the exterior tube, the interior member configured to constrain the endoprosthesis relative to the exterior tube;
- and
- a funnel surrounding the interior member adjacent a distal end of the exterior tube and comprising a tear away strip, the funnel assisting the endoprosthesis in transitioning from an uncompressed state to a compressed state as the exterior tube is slid over the interior tube.
2 more elements
A method of mounting an endoprosthesis on a delivery device comprising:
- providing a stent, a loading tool having an interior tube slideably mounted within an exterior tube and a loading funnel attached to a distal end of the exterior tube, the loading funnel having a tear away strip suitable for detaching the funnel from the exterior tube;
- loading an uncompressed endoprosthesis about the delivery device;
- advancing the exterior tube over the stent and thereby causing the endoprosthesis to be compressed about the delivery device;
- and
- removing the loading funnel by tearing away the tear away strip.
