First Claim
Patent Images
1. A stent delivery system comprising:
- an inner elongate body and an outer elongate tubular body which are co-axially arranged,a pull-back device enabling proximal displacement of the outer body with respect to the inner body for releasing a stent contained within an annular cavity formed between the inner and outer body, into a body lumen,a device for passing fluid into the annular cavity having a housing with a distal end, a proximal end and an off-axis end, the housing provides a seating at the distal end thereof for the outer elongate tubular body along an axis of the housing extending between the proximal and the distal end, the distal and off-axis ends defining respective openings which are in fluid communication with each other, and the proximal end having a lumen to enable the inner elongate body to extend from the housing both distally and proximally, along the axis thereof,the stent delivery system being characterized by a locking and release device mounted to the housing and extending into the off-axis opening of the housing to bear, in a locking disposition, against the inner body to prevent axial movement thereof with respect to the outer body, and to simultaneously allow injection of fluid into the annular cavity and, in a released disposition, to be spaced from the inner body to permit axial movement of the inner body with respect to the outer body.
