Claim 0:
1. A medical device, comprising:
a retriever sub-system adapted to remove first unwanted material from a vessel of a patient, said retriever sub-system comprising an elongated member, a proximal element, a distal element, element disengagement means and a handle,
said elongated member comprising a first proximal end and a first distal end,
said proximal element comprising a first proximal end point and a first distal end point, said first proximal end point of said proximal element releasably engaged to a first portion of said elongated member and said first distal end point of said proximal element releasably engaged to a second portion of said elongated member, whereby, when said first proximal end point and said first distal end point of said proximal element are released from said elongated member, said proximal element is allowed to slidably translate along said elongated member,
said proximal element adapted to expand from a first pre-expansion configuration to a first expanded configuration, and from said first expanded position to a first contracted configuration,
said distal element comprising a second proximal end point and a second distal end point, said second proximal end point engaged to a third portion of said elongated member, said second distal end point engaged to a fourth portion of the elongated member,
said first portion, second portion, third portion, and fourth portion of said elongated member representing different locations along said elongated member,
said distal element adapted to expand from a second pre-expansion configuration to a second expanded configuration, and from said second expanded position to a second contracted configuration,
said element disengagement means adapted to release said first proximal end point of said proximal element and said first distal end point of said proximal element from said elongated member,
said handle in physical communication with said elongated member, said handle comprising a first physically manipulable interface and a second physically manipulable interface,
said first physically manipulable interface adapted to selectably mechanically induce said expansion of said proximal element from said first pre-expansion configuration to said first expanded configuration or said contraction of said proximal element from said first expanded position to said first contracted configuration or mechanically induce said expansion of said distal element from said second pre-expansion configuration to said second expanded configuration, and from said second expanded position to said second contracted configuration when said first physically manipulable interface is moved,
said second physically manipulable interface adapted to induce first slidable translation of said proximal element along said elongated member without inducing second slidable translation of said distal element along said elongated member when said first proximal end point and said first distal end point of said proximal element are released from said elongated member and said second physically manipulable interface is moved; and
an aspiration sub-system in communication with said retriever sub-system, said aspiration sub-system also adapted to remove said first unwanted material from said vessel of said patient.
