摘要： A clot removal device for removal of an occlusion from a lumen in a patient's body is provided. The clot removal device has a lumen, an elongated member positioned within the lumen and extending axially from a proximal end to a distal end of the lumen, a handle attached to the proximal end of the lumen, a first expandable member positioned along a length of the elongated member, a second expandable member positioned along the length of the elongated member, wherein the second expandable member is distal to the first expandable member relative to the handle. The handle has at least one actuation mechanism and at least one of the following applies: a) the first expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the second expandable member upon manipulation of the at least one actuation mechanism; b) the first expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism; c) the second expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the first expandable member upon manipulation of the at least one actuation mechanism; or d) the second expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism.

摘要： Provided herein are methods and systems for the removal of anatomical occlusions, and an occlusion removal device comprising a first body adapted to be mounted to a delivery wire and releasably engaged to the delivery wire, wherein while engaged the first body remains fixed on the delivery wire and upon release moves axially along the delivery wire, and a second body adapted to be mounted to the delivery wire. A first proximal body may be oriented proximally to a second distal body. The proximal body and the distal body may be adapted to expand upon exiting a delivery catheter. The proximal body may be releasably engaged by a mechanically breakable connection or an electrolytically or heat disconnectable connection, the electrolytically disconnectable connection being broken upon an application of electric current to the electrolytically disconnectable connection.

摘要： A retriever device for removal of unwanted material from a vessel in a patient's body comprising a retriever sub-system and an aspiration sub-system. The retriever sub-system comprising a delivery catheter and a delivery wire having first and second expandable bodies disposed thereon that are adapted to expand from a pre-expansion configuration to an expanded configuration. The second expandable body is further adapted to slidably translate along the delivery wire in a distal direction toward the first expandable body when the second expandable body is released from the delivery wire, whereby, when the first expandable body is disposed on a distal side of at least a first portion of the unwanted material in the vessel and the second expandable body is disposed on a proximal side of the first portion of the unwanted material, the first expandable body and the second expandable body surround and contain the first portion of the unwanted material between the first expandable body and the second expandable body. The aspiration sub-system is adapted to remove at least a second portion of the unwanted material from the vessel. The aspiration sub-system also includes a pressure sensor adapted to monitor internal vessel pressure proximate an internal region of the vessel.
