Abstract:
An endoscopic instrument for severing and capturing a polyp from a patient, the instrument comprising:a catheter having a distal end and a proximal end; a first cable extending between said distal end and said proximal end of said catheter; a snare for severing the polyp from the patient, said snare being coupled to a distal end of said first cable and being at least partially extensible from and at least partially retractable into said distal end of said catheter; second cable extending between said distal end and said proximal end of said catheter; a self-expansible forceps for holding the severed polyp, said forceps being coupled to a distal end of said second cable and being at least partially extensible from and at least partially retractable into said distal end of said catheter, said snare and said forceps configured so that said forceps is capable of holding a portion of the polyp to be severed and removed while said snare severs the polyp; a needle for piercing the polyp, said needle coupled to said distal end of said second cable; and a control device coupled to said proximal end of said catheter for extending and retracting said snare and for extending and retracting said forceps and said needle relative to said distal end of said catheter.
