摘要:
A clot removal device and method for removing a clot from a blood vessel may include an expandable clot engagement element, an expandable clot capture element, and a sheath surrounding and compressing the capture element and the engagement element. The sheath may be removable to thereby enable the capture element to expand in a blood vessel in which the sheath is deployed, and to enable the engagement element to expand within the capture element. Additionally, a clot removal device and method for removing a clot from a blood vessel may employ a tubular clot capture element for deployment in a blood vessel for surrounding a clot, such that when the clot capture element surrounds a clot and is retracted in a longitudinal direction of the blood vessel, the clot capture element is configured to exert a radially inward compression force on the clot. Further, a clot removal device and method may include a tubular clot capture element having a first internal diameter and a clot engaging element having a second external diameter. The first diameter and the second diameter may be selected to permit the clot engaging element to be rotated within the tubular clot capture element. Further still, a clot removal device and method may employ a shaft and a clot engagement element on an end of the shaft, both configured for deployment in a blood vessel. The clot removal device may also include a stabilizer configured to at least partially surround the shaft and to maintain a portion of the shaft in a non-contacting relationship with the blood vessel wall.L'invention porte sur un dispositif et sur un procédé de retrait de caillot pour retirer un caillot à partir d'un vaisseau sanguin, lesquels peuvent mettre en œuvre un élément de prise de caillot extensible, un élément de capture de caillot extensible, et un manchon entourant et comprimant d'élément de capture et l'élément de prise. Le manchon peut être amovible de façon à permettre ainsi à l'élément de capture de se dilater dans un
