1. A system for treating a pulmonary embolism, comprising:
- an elongated member having a proximal portion and a distal portion; and
a clot treatment device having a proximal portion fixed to the distal portion of the elongated member, the clot treatment device including;
an expandable generally cylindrical portion; and
a plurality of capture elements including at least a first capture element and a second capture element, wherein the generally cylindrical portion is positioned between the first and second capture elements, and wherein the generally cylindrical portion and the capture elements are configured to move from a low-profile undeployed state sized to fit within a delivery catheter to a deployed state in which the generally cylindrical portion has a first cross-sectional dimension greater than that of the low-profile state and the capture elements project outwardly from the generally cylindrical portion,wherein the generally cylindrical portion has a first longitudinal dimension and each of the capture elements has a second longitudinal dimension, the first longitudinal dimension being greater than the second longitudinal dimension.

Abstract
A method and apparatus for treating a clot in the blood vessel of a patient, and particularly the treatment of a pulmonary embolism is disclosed. The treatment includes restoring flow through the clot followed by clot removal, either partially or substantially completely. The clot treatment device is expandable into the blood vessel and may contain radial extensions that assist in restoring flow as well as in removing clot material.

15. A pulmonary embolism treatment device, comprising:
-
an outer elongated member having a distal end; an inner elongated member within the outer elongated member, wherein the inner elongated member and the outer elongated member slides relative to each other, and wherein the inner elongated member has a distal end; and an expandable member having a proximal portion fixed to the distal end of the outer elongated member and a distal portion fixed to the distal end of the inner elongated member, the expandable member having a generally cylindrical portion and a plurality of capture elements arranged along the generally cylindrical portion, wherein the generally cylindrical portion and the capture elements are configured to move from a low-profile undeployed state sized to fit within a delivery catheter to a deployed state in which the generally cylindrical portion has a first cross-sectional dimension greater than that of the low-profile state and the capture elements project outwardly from the generally cylindrical portion, wherein the generally cylindrical portion has a first longitudinal dimension and each of the capture elements has a second longitudinal dimension, the first longitudinal dimension being greater than the second longitudinal dimension. - View Dependent Claims (16, 17, 18, 19, 20)
