Clot retrieval device for removing clot from a blood vessel
First Claim
1. A device for removing clot from a blood vessel, the device having a collapsed delivery configuration and an expanded deployed configuration and comprising:
- a shaft;
an expandable body coupled to the shaft and radially expandable to the deployed configuration, and havingan inner expandable body fixedly coupled to a distal region of the shaft, andan outer expandable body fixedly coupled to the distal region of the shaft and having an open distal end, anda capture net coupled to the inner expandable body and including a proximal mouth;
wherein a proximal most end of the inner expandable body is coextensive with a proximal most end of the outer expandable body.

Abstract
A clot retrieval device (9501) for removing clot from a blood vessel comprises an inner elongate body (9503) and an outer elongate body (9504) at least partially overlying the inner elongate body (9503). The device also comprises an elongate member or shaft (9502) having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (9502). The outer elongate body (9504) and the inner elongate body (9503) are connected to the distal end of the shaft (9502) and are expandable relative to the shaft (9502) from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body (9504) is expandable relative to the inner elongate body (9503) to a radial extent which is greater than the radial extent of the inner body (9503) in the deployed configuration.
