Abstract
An aspiration sheath system for aspirating occlusive material from a blood vessel is disclosed. The aspiration sheath system may be configured to have the ability to be unclogged, while retaining the position of the aspiration sheath in the target vasculature. The system includes an aspiration sheath including an elongate shaft extending distally from a manifold, an aspiration sleeve having an elongate shaft slidably disposed within a lumen of the aspiration sheath, and a dilator having an elongate shaft slidably disposed within an aspiration lumen of the aspiration sleeve.
Claims20
An aspiration sheath system comprising:
- an aspiration sheath including an elongate shaft extending distally from a manifold, the aspiration sheath having a lumen extending therethrough;
- an aspiration sleeve having an elongate shaft slidably disposed within the lumen of the aspiration sheath, the aspiration sleeve having an aspiration lumen extending therethrough;
- and
- a dilator having an elongate shaft slidably disposed within the aspiration lumen of the aspiration sleeve.
An aspiration sheath system comprising:
- an aspiration sheath including an elongate shaft extending from a manifold to a distal end, the elongate shaft having a lumen extending therethrough;
- an aspiration sleeve having an elongate shaft and a hub at a proximal end thereof, the elongate shaft of the aspiration sleeve configured to be inserted through the lumen of the aspiration sheath;
- and
- a vacuum source fluidly coupled to the hub of the aspiration sleeve for providing aspiration through an aspiration lumen of the aspiration sleeve.
A method of aspirating occlusive material from a blood vessel, the method comprising:
- advancing an aspiration sheath having an aspiration sleeve and a dilator disposed therein to a treatment site within a blood vessel;
- withdrawing the dilator from the aspiration sleeve while maintaining the aspiration sleeve within the aspiration sheath;
- creating suction through the aspiration sleeve to aspirate occlusive material from the blood vessel;
- withdrawing the aspiration sleeve from the aspiration sheath while maintaining the position of the aspiration sheath at the treatment site;
- and
- creating suction through the aspiration sheath to continue aspirating occlusive material from the blood vessel.
