主权项

1. A catheter assembly comprising:
at least one catheter shaft having a distal end and a proximal end, a distal tip disposed at the distal end and a longitudinal axis; a stent disposed about the distal end of the catheter shaft; a product mandrel, the product mandrel removably disposed within the catheter shaft, and exposed at the distal end of the catheter shaft and distal of the distal tip; a stent protector having an inner surface and an outer surface and having a proximal end and a distal end, the stent protector having a first stent covering region having a first inner diameter defined by the inner surface and disposed about the stent without substantially engaging the stent, a second stent covering region having a second inner diameter defined by the inner surface which is less than the first inner diameter located distal of the first stent covering region disposed about the catheter shaft distal tip, a first connecting region connecting the first stent covering region and the second stent covering region, an engagement region having a third inner diameter defined by the inner surface which is less than the second inner diameter, the engagement region engaging the product mandrel, and a second connecting region connecting the second stent covering region and the engagement region and wherein the product mandrel and the stent protector are removed from the catheter assembly prior to use.
