Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
76 words
An apparatus for fragmenting and drilling urinary calculi comprising a catheter adapted to be inserted into a ureter to abut the calculi to be removed, a coupling member extending lengthwise of the lumen of said catheter and having a diameter less than the diameter of said lumen whereby said coupling member may vibrate transversely within the catheter and ultrasonic means acting on the coupling member to cause transverse vibration of the end thereof adjacent the calculi.
Claim 2
Independent Claim
76 words
An apparatus for fragmenting and drilling urinary calculi comprising a catheter adapted to be inserted into a ureter to abut the calculi to be removed, a coupling member extending lengthwise of the lumen of said catheter and having a diameter less than the diameter of said lumen whereby said coupling member may vibrate transversely within the catheter and ultrasonic means acting on the coupling member to cause transverse vibration of the end thereof adjacent the calculi.
Claim 3
Dependent Claim
23 words
An apparatus as claimed in claim 1 wherein the diameter of the coupling member is less than two-thirds the diameter of the lumen.
Claim 4
Dependent Claim
14 words
An apparatus as claimed in claim 1 wherein the coupling member is a wire.
Claim 5
Independent Claim
115 words
A method for fragmenting and drilling urinary calculi comprising th steps of: a. placing a catheter in a ureter containing a calculi to be removed with one end abutting the calculi and the other end free, b. inserting a coupling member through the lumen of said catheter until one end abuts the calculi while the other end extends out of the free end of the catheter, said coupling member having a smaller diameter than the lumen diameter, c. subjecting the coupling member to ultrasonic vibrations such that transverse vibrations are produced at the end abutting the calculi, and d. moving the coupling member into the catheter to cause it to fragment and drill the calculi.
Claim 6
Independent Claim
115 words
A method for fragmenting and drilling urinary calculi comprising th steps of: a. placing a catheter in a ureter containing a calculi to be removed with one end abutting the calculi and the other end free, b. inserting a coupling member through the lumen of said catheter until one end abuts the calculi while the other end extends out of the free end of the catheter, said coupling member having a smaller diameter than the lumen diameter, c. subjecting the coupling member to ultrasonic vibrations such that transverse vibrations are produced at the end abutting the calculi, and d. moving the coupling member into the catheter to cause it to fragment and drill the calculi.
Claim 7
Dependent Claim
29 words
A method as claimed in claim 4 wherein the coupling member is a wire whose diameter is less than two-thirds of the diameter Of the lumen of the catheter.
Claim 8
Dependent Claim
38 words
A method as claimed in claim 4 wherein a cystoscope is inserted in the urinary tract to at least the bladder and the catheter is inserted through the cystoscope into the bladder and from thence into the ureter.
Claim 9
Dependent Claim
26 words
A method as claimed in claim 4 wherein flushing fluid is introduced into the catheter whereby the catheter is irrigated with fluid during fragmenting and drilling.
Claim 10
Dependent Claim
25 words
An apparatus as claimed in claim 1 wherein the coupling member has a wave form adjacent the point when the ultrasonic means acts upon it.
Claim 11
Dependent Claim
25 words
An apparatus as claimed in claim 1 wherein the coupling member has a spiral form adjacent the end where the ultrasonic means acts upon it.
Claim 12
Dependent Claim
20 words
An apparatus as claimed in claim 1 wherein the ultrasonic means acts on the coupling member transversely to its length.
