Abstract
A method and system of coating an implantable device, such as a stent, are provided.
Claims30
A method of coating an implantable device comprising:
- applying a composition including a solvent to an implantable device;
- and
- actively directing a gas from a blowing means onto the implantable device, wherein if the solvent has a vapor pressure greater than 17.54 Torr at ambient temperature the temperature of the gas is adjusted to inhibit the evaporation of the solvent, and if the solvent has a vapor pressure of less than 17.54 Torr at ambient temperature the temperature of the gas is adjusted to induce the evaporation of the solvent.
A method of coating an implantable device comprising:
- applying a composition including a solvent to an implantable device;
- and
- directing a gas onto the implantable device, wherein if the solvent has a vapor pressure greater than 17.54 Torr at ambient temperature the temperature of the gas is adjusted to inhibit the evaporation of the solvent, and if the solvent has a vapor pressure of less than 17.54 Torr at ambient temperature the temperature of the gas is adjusted to induce the evaporation of the solvent, wherein the act of directing the gas is performed at a flow rate of about 300 feet/minute to about 10,000 feet/minute.
A method of coating an implantable device comprising:
- applying a composition including a solvent to an implantable device;
- and
- actively directing a gas from a blower means onto the implantable device simultaneous with application of the composition to either induce or inhibit evaporation of the solvent from the composition to form a coating on the implantable device, wherein if the solvent is non-volatile the temperature of the gas is adjusted to induce the evaporation of the solvent, and if the solvent is volatile the temperature of the gas is adjusted to inhibit the evaporation of the solvent.
