Electrophysiological diagnostic catheter especially for obtaining of endomyocardial biopsy of heart tissue
First Claim
Patent Images
1. An electrophysiological diagnostic catheter to obtain an endomyocardial biopsy of heart tissues and to be guided and monitored by an electroanatomical 3D mapping system, the catheter comprising:
- a main tube being flexible in a deployed configuration and having a distal end and a proximal end;
a manipulation handgrip on said main tube adjacent said proximal end;
a plurality of diagnostic rings on said main tube, wherein at least one diagnostic ring is a distal ring at said distal end of said main tube; and
a bioptome removably engaged to said main tube, said bioptome being comprised of a forceps, a hinge, and a bioptome tube,wherein said main tube is comprised of an internal channel with distal opening at said distal ring and a proximal opening as said proximal end, said internal channel being centrally located in said main tube,wherein said distal opening is in fluid connection with said proximal opening, andwherein said bioptome has a stand-by configuration relative to said main tube with said forceps and said distal ring forming a rounded arc at said distal end.

Abstract
The electrophysiological diagnostic catheter obtains an endomyocardial biopsy of heart tissues. The catheter includes a manipulation handgrip, main channel, distal ring and diagnostic rings connected with electrical connections. There is a centrally located, open internal channel, wherein inlet/outlet of internal channel is located in the distal ring, or is guided and monitored using a system for 3D electroanatomical mapping.
