摘要:
A drug eluting stent is disclosed. The stent includes a stent base; a basecoat formulation comprising Sirolimus in a polymer coating, wherein the polymer coating contains ethylene-co-vinyl acetate and poly-n-butyl methacrylate; and a topcoat disposed on the basecoat formulation.
摘要:
A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.
摘要:
A patterned coating on a prosthesis, for example a stent, and a method for forming the coating are disclosed Additionally, an apparatus for forming the patterned coating is disclosed.
摘要:
A method for crimping a stent onto a balloon includes inflating a balloon with a fluid, sliding a stent over the inflated balloon, crimping the stent onto the balloon, and controlling the pressure inside the balloon below a given value when the stent is being crimped onto the balloon.
摘要:
A medical device such as a stent with a catheter, delivery balloon and an infrared energy source is disclosed. The infrared energy source heats the delivery balloon, and/or the stent to a temperature above body temperature, thereby increasing the flexibility of the stent such that formation of cracks in the stent upon its expansion is reduced or eliminated. Either the delivery balloon, and/or the stent may include an infrared energy absorbing material.
