Abstract
The present invention provides an embolectomy device for removal of clots from vasculature, said device comprising: a proximal effecter characterized by a non-expanded configuration and an expanded configuration; a distal effecter characterized by a non-expanded configuration and an expanded configuration; said proximal effecter, in said expanded configuration is adapted for grasping a proximal portion of the target embolus; said proximal effecter, in said expanded configuration is adapted for grasping a distal portion of said target embolus; wherein both said effecters, when expanded, are oppositely positioned and are adapted to operate in concert, for trapping said clot such that said clot is (i) manipulatable along and/or around the main longitudinal axis of said vasculature in a predetermined set of motions; (ii) extracted out of said vasculature.

45. An embolectomy device for removal of clots from vasculature, said device comprising:
-
a. a proximal effecter characterized by a non-expanded configuration and an expanded configuration; b. a distal effecter characterized by a non-expanded configuration and an expanded configuration; said proximal effecter, in said expanded configuration is adapted for grasping a proximal portion of the target embolus;
said proximal effecter, in said expanded configuration is adapted for grasping a distal portion of said target embolus;wherein both said effecters, when expanded, are oppositely positioned and are adapted to operate in concert, for trapping said clot such that said clot is (i) manipulatable along and/or around the main longitudinal axis of said vasculature in a predetermined set of motions;
(ii) extracted out of said vasculature. - View Dependent Claims (46, 47, 48, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73)

74. A method for removing a clot from blood vessel, comprising steps of:
-
i. obtaining an embolectomy device comprising; a. a proximal effecter characterized by a non-expanded configuration and an expanded configuration; b. a distal effecter characterized by a non-expanded configuration and an expanded configuration; ii. approximating said clot; iii. crossing said clot via said distal effecter in said an expanded configuration; iv. reconfiguring said distal effecter from said an expanded configuration to said expanded configuration; v. reconfiguring said proximal effecter from said an expanded configuration to said expanded configuration; vi. grasping both the proximal portion of said clot via said proximal effecter and the distal portion of said clot via said distal effecter; vii. manipulating said clot along and/or around the main longitudinal axis of said blood vessel in a predetermined set of motions;
thereby separating said clot from the walls of said blood vessel; and
,viii. extracting said clot confined from said blood vessel. - View Dependent Claims (75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88)
