Abstract
A location within a patient may be visualized while reducing potential impact on the patient's anatomy. A contrast media may be injected into a location within the patient's vasculature. The location may be viewed fluoroscopically. At least some of the injected contrast media may be recaptured in order to reduce a quantity of contrast media reaching the patient's anatomy.
Claims20
A method for visualizing a location within a patient while reducing potential impact on the patient's anatomy, the method comprising:
- injecting a contrast media into a location within the patient's vasculature;
- viewing the location fluoroscopically;
- and
- recapturing at least some of the injected contrast media.
An assembly for visualizing a location within a patient while reducing potential impact on the patient's anatomy, the assembly comprising:
- an injection catheter including:
- an injection lumen extending therethrough;
- one or more injection ports fluidly coupled with the injection lumen for injecting contrast media;
- and
- an aspiration catheter including:
- an aspiration lumen extending therethrough;
- and
- one or more aspiration ports fluidly coupled with the aspiration lumen.
A catheter, comprising:
- an elongate shaft;
- an injection lumen extending through the elongate shaft;
- one or more injection ports fluidly coupled with the injection lumen for injecting contrast media;
- an aspiration lumen extending through the elongate shaft;
- and
- one or more aspiration ports fluidly coupled with the aspiration lumen, the one or more aspiration ports disposed proximally of the one or more injection ports.
