Abstract
Abstract This invention related to a catheter comprising a tube-like basic body with a proximal and a distal end and a high-frequency generator associated with the catheter used for the purpose of generating high-frequency mechanical vibrations at the distal end of the catheter. The catheter comprises a lumen to be filled with liquid which is connected at the proximal end to an area inside of which a high-frequency movable member of the high-frequency generator is located and wherein at the distal end of the catheter a guide have been arranged for deflecting high frequency longitudinal waves traveling through the liquid inside the lumen in a lateral direction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
Catheter comprising: a tube-like catheter body with a proximal end and a distal end; and a high-frequency generator associated with the catheter used for the purpose of generating high-frequency mechanical vibrations at the distal end of the catheter, said generator containing a readily manipulable projecting member; and said catheter comprising a lumen, said catheter connected at its proximal end to an area inside of which at least a portion of said high-frequency generator can be inserted and located; and wherein guiding means are arranged said guiding means arranged at the distal end of the catheter, for deflecting in a lateral direction high-frequency longitudinal waves generated by said generator; a suction inlet connected within a discharge lumen in the catheter body; and a pressure lumen connected to a jet nozzle directed in a proximal direction past said suction inlet; said pressure lumen for generating suction by means of pressure differential within said lumen.
Claim 2
Dependent Claim
152 words
Catheter comprising: a tube-like catheter body with a proximal end and a distal end; and a high-frequency generator associated with the catheter used for the purpose of generating high-frequency mechanical vibrations at the distal end of the catheter, said generator containing a readily manipulable projecting member; and said catheter comprising a lumen, said catheter connected at its proximal end to an area inside of which at least a portion of said high-frequency generator can be inserted and located; and wherein guiding means are arranged said guiding means arranged at the distal end of the catheter, for deflecting in a lateral direction high-frequency longitudinal waves generated by said generator; a suction inlet connected within a discharge lumen in the catheter body; and a pressure lumen connected to a jet nozzle directed in a proximal direction past said suction inlet; said pressure lumen for generating suction by means of pressure differential within said lumen.
Claim 3
Dependent Claim
41 words
Catheter as claimed in claim 1, wherein the high-frequency generator comprises an element excitable by means of electrical vibrations at its distal end and electrical lines extend from the proximal end of the catheter, through said tube-like body, to the element.
Claim 4
Dependent Claim
14 words
Catheter as claimed in claim 2, wherein the excitable element is a piezo-electric element.
Claim 5
Dependent Claim
14 words
Catheter as claimed in claim 1, wherein the high-frequency generator further comprises a frequency-adjusting-element.
