An intravascular snare device for use in capturing debris found in blood vessels. The snare device is fabricated from a tube and includes longitudinally and circumferentially extending members. The snare device specifically embodies structure that provides enhanced radial opening and angular resistance to collapse.

Snare

A self-expanding, pseudo-braided device embodying a high expansion ratio and flexibility as well as comformability and improved radial force. The pseudo-braided device is particularly suited for advancement through and deployment within highly tortuous and very distal vasculature. Various forms of the pseudo-braided device are adapted for the repair of aneurysms and stenoses as well as for use in thrombectomies and embolic protection therapy.

Self-expanding pseudo-braided intravascular device

Expandable emboli filter and thrombectomy devices adapted for use with microcatheters to remove debris from blood vessels. The devices embody expanded profiles that span the entirety of various sized target vessels and thus are particularly effective in the engagement of debris found in vessels.

Expandable emboli filter and thrombectomy device

An organ manipulator including at least one suction member or adhesive disk mounted to a joint providing freedom of movement of the at least one suction member or adhesive disk relative to its support. A method for retracting and maintaining an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) is provided.

Organ manipulator having suction member supported with freedom to move relative to its support

An organ manipulator including at least one suction member or adhesive disc mounted to a joint providing freedom of movement of the at least one suction member or adhesive disk relative to its support. A method for retracting and suspending an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) in at least the vertical direction during both steps.

An organ manipulator including at least one suction member or adhesive disk mounted to a joint providing freedom of movement of the at least one suction member or adhesive disk relative to its support. A method for retracting and suspending an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) in at least the vertical direction during both steps.

An extraction device for the removal of clots and foreign bodies from vasculature. The extractor device is connected to an elongate mandrel and is located within a longitudinally extending lumen defined by a catheter. A clot or foreign material extracted from a vessel by moving the extraction device and catheter proximally until the clot or foreign material does not perfuse a critical organ.

Filter/emboli extractor for use in variable sized blood vessels

A device that is useful for removing obstructions from vessels. Various embodiments and methods of use are contemplated for the effective removal of obstructions. The disclosed devices utilize a thrombogenic material to promote the formation of fibrin bonds, thus enhancing adhesion. It is further contemplated that the disclosed devices may be used in all vasculature including the cerebral vasculature and the neurovasculature.

Device for removal of thrombus through physiological adhesion

An organ manipulator including at least one suction member or adhesive disc mounted to a compliant joint, a flexible locking arm for mounting such suction member or compliant joint, and a method for retracting and suspending an organ in a retracted position using suction (or adhesive force) so that the organ is free to move normally (e.g., to beat or undergo other limited-amplitude motion) in at least the vertical direction during both steps. In preferred embodiments, a suction member exerts suction to retract a beating heart and suspend it in a retracted position during surgery. As the retracted heart beats, the compliant joint allows it to expand and contract freely (and otherwise move naturally) at least in the vertical direction so that hemodynamic function is not compromised. The suction member conforms or can be conformed to the organ anatomy, and its inner surface is preferably smooth and lined with absorbent material to improve traction without causing trauma to the organ. The compliant joint can connect the member to an arm which is adjustably mounted to a sternal retractor or operating table. The compliant joint can be a sliding ball joint, a hinged joint, a pin sliding in a slot, a universal joint, a spring assembly, or another compliant element. In preferred embodiments, the method includes the steps of affixing a suction member to a beating heart at a position concentric with the heart's apex, and applying suction to the heart while moving the member to retract the heart such that the heart has freedom to undergo normal beating motion at least in the vertical direction during retraction.

An organ-stabilizing element is covered with a layer of textile material such as cloth to enhance slip-free engagement with an organ such as a beating heart during surgery thereon. The organ-stabilizing element is supported on a stacked structure of successive ball elements and rings that can be selectively flexible or rigid in response to tensioning of a flexible cable within a central bore of the structure.

Organ stabilizer and method

A flexible locking arm for use in an organ manipulator apparatus. The flexible locking arm has a flexible state, used to position the organ manipulator as needed, and a fixed state for mounting the manipulator in a desired orientation. Even in the fixed state, the organ manipulator maintains a limited freedom of movement, to allow the organ held to continue to move substantially according to its natural motion during functioning. For example, in an embodiment where a suction member exerts suction to retract a beating heart and suspend it in a retracted position during surgery by setting the flexible arm to the fixed state, as the retracted heart beats, a complaint joint allows it to expand and contract freely (and otherwise move naturally) at least in the vertical direction so that hemodynamic function is not substantially compromised.
