Definitions
- an unexpended stent is permanently implanted in the body by percutaneously inserting it into a vessel using a catheter, and guiding the stent to the site where it is to be permanently implanted.
- the balloon portion of the catheter is inflated and the stent expanded, solely as a result of the mechanical force applied by the expanding balloon, until the stent is sized appropriately for the implantation site. Thereafter, the expanded balloon is deflated, and the catheter is removed from the body, leaving the stent permanently in position.
- the method described by Pathak poses the risk that the balloon may be damaged by overheating.
- compounding the chromophore with the polymer by thermal means can alter its light-absorbing properties or degrade it significantly. Chromophores which are compounded with polymers and extruded to make stents may become photo-bleached, altering their absorption properties and making precise and repeatable deployment difficult. Chromophores can also chemically react with the polymer during heating, leading to cross-linking which may alter the physical properties of the polymer.
- FIG.6 is a graph showing the relationship between the temperature of the stent, the current of the laser providing optical radiation, and the time of exposure to optical radiation in accordance with practice of the present invention.
- the concentration of radiation-absorbing material used in the contrast medium may be determined empirically.
- indocyanine green (“ICG”) is used in both the coating and in the contrast medium, in a concentration of 48.1 mg ICG/g poly (D,L- lactide) in the coating, and between about 0.15 and about 0.4 mg/mL, preferably 0.2 mg/mL, in the contrast medium. If the concentration of indocyanine green in the contrast medium is too high, about 0.5 mg/mL or higher, insufficient radiation penetrates the medium and only the contrast medium near the diffuser lumen is heated. Under these circumstances, the medium near the diffuser may become overheated and damage the diffuser.
- thermocouple The temperature sensed by the thermocouple is fed into a controller system, preferably a proportional-integral-differential controller system, that modulates the power emitted from the diffuser, preferably by modulating the power emitted from the radiation provider, thereby maintaining the stent temperature to within a range above the glass transition temperature that permits stent expansion yet does not adversely overheat the tissue adjacent to the stent, preferably the stent temperature is maintained between about 38 ° C and about 60 ° C depending upon the molecular composition of the stent.
- a controller system preferably a proportional-integral-differential controller system, that modulates the power emitted from the diffuser, preferably by modulating the power emitted from the radiation provider, thereby maintaining the stent temperature to within a range above the glass transition temperature that permits stent expansion yet does not adversely overheat the tissue adjacent to the stent, preferably the stent temperature is maintained between about 38 ° C and about 60 ° C depending upon the
- optical radiation is provided to the stent coating via a diffuser contained within the lumen of the balloon on which the stent is deployed.
- the internal diffuser is connected to an external laser, which provides optical radiation to the diffuser via optical fibers.
- the radiation source will be contained in a single device as, for example, in an ultrasonic transducer. In such embodiments, the radiation source may be completely contained within the balloon and not dependant on an external component. It is to be understood that both embodiments, that is, those in which the radiation source includes an internal and an external component, and those in which the radiation source is contained in a single internal component, are provided in accordance with practice of the present invention.
- the stent was placed upon a Schneider Total Cross 0.021 -inch balloon (6 mm diameter, 2 cm length; Schneider (USA), Inc.) with a thermocouple between the balloon and the stent.
- a 3 cm long, 0.019-inch diameter, optical diffuser (Lightstik®, Rare Earth Medical, Inc.) was inserted into the lumen of the balloon, and an optical fiber connected the diffuser to the continuous wave output of a diode laser emitting 790.7 nm radiation (Opto Power Corp., model OPC-D010-B05-HPHS/250, maximum output power at 10 W).
