Abstract
A clot retrieval apparatus 1 comprises a clot engaging device 2 and a capture basket 3. The clot engaging device 2 has a collapsed delivery configuration and an expanded deployment configuration. The clot engaging device has a proximal end and a distal end and an elongate body between the proximal end and the distal end. The capture basket 3 has a collapsed delivery configuration and an expanded deployment configuration. The capture basket 3 has a proximal mouth which is open when the capture basket 3 is in the deployment configuration. The clot engaging device 2 is axially movable relative to the capture basket for capture of a clot.
Claims20
A clot retrieval apparatus, comprising:
- a handle;
- a clot engaging device located distally of the handle and having a collapsed delivery configuration and an expanded deployment configuration, the clot engaging device having a proximal end and a distal end and an intermediate body section between the proximal end and the distal end, the clot engaging device being connected to a first elongate shaft element;
- a capture basket located distally of the clot engaging device and having a collapsed delivery configuration and an expanded deployed configuration, the capture basket having a proximal mouth formed by a proximal mouth structure, the proximal mouth being open when the capture basket is in the expanded deployed configuration, a distalmost end of the proximal mouth structure being located at the proximal end of the capture basket, the capture basket being connected to a second elongate shaft element at a first portion of the proximal mouth structure;
- a control tether coupled to the proximal mouth at a second portion of the proximal mouth structure and selectively movable to adjust an orientation of the proximal mouth in the expanded deployed configuration, the second portion of the proximal mouth structure being different than the first portion of the proximal mouth structure, and
- the first and second shaft elements being movable relative to one another such that the clot engaging device is axially movable relative to the capture basket,
- wherein the distal end of the clot engaging device has a radial size smaller than a radial size of the intermediate body section and of the proximal mouth of the capture basket.

A clot retrieval apparatus, comprising:
- a handle;
- a clot engaging device located distally of the handle having a collapsed delivery configuration and an expanded deployed configuration, the clot engaging device including a body having
- a plurality of struts forming a plurality of closed cells,
- a proximal end,
- an intermediate section, and
- a distal end, and
- the clot engaging device being connected to a first elongate shaft element;
- and
- a capture basket located distally of the clot engaging device and having a collapsed delivery configuration and an expanded deployed configuration, the capture basket having a proximal mouth formed by a proximal mouth structure coupled to a control member and open when the capture basket is in the expanded deployed configuration, a distalmost end of the proximal mouth structure being located at the proximal end of the capture basket the control member movable between a first position in which the proximal mouth in the expanded deployed configuration is at a first radial orientation relative to the control member, and a second position in which the proximal mouth in the expanded deployed configuration is at a second radial orientation relative to the control member, the capture basket being connected to a second elongate shaft element at a first location along the proximal mouth structure and the control member being connected to the capture basket at a second location along the proximal mouth structure, the second location being spaced from the first location, and
- the first and second shaft elements being movable relative to one another such that the clot engaging device is axially movable relative to the capture basket wherein, in the expanded deployed configuration, the distal end of the clot engaging device has a radial size which is smaller than a radial size of the intermediate section and of the proximal mouth of the capture basket.
