Abstract:
A single operator exchange fluid jet thrombectomy device, suitable for insertion into a body vessel or other body cavity in order to remove undesirable matter therefrom, the device comprising:a. an outer assembly including: (1) a manifold including a proximal end and a distal end; and, (2) a first tube extending from the distal end of the manifold, the first tube having a proximal end and an open distal end; b. at least one inner assembly, each inner assembly characterized by an ability to separate from the outer assembly and be exchanged for a different inner assembly and to pass through the first tube of the outer assembly, and wherein at least one inner assembly includes: (1) a high pressure second tube having a proximal end, a distal end, a high pressure lumen, and a geometrically configured distally located jet emanator; and, (2) a flow director means attached to the high pressure second tube adjacent to, spaced apart from, and proximal to the jet emanator, the flow director means having a lumen; and, c. said flow director means and said first tube of said outer assembly defining an annulus and said flow director means positionable to at least partially restrict the annulus thereby providing a substantial fluid seal means between said flow director means and said first tube of said outer assembly.
