Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A system for evaluating female urinary incontinence, comprising: a catheter having at least one pressure sensor positioned thereon; means for supporting the catheter to allow movement of the catheter in response to a pelvic pressure pulse, wherein the movement of the catheter tracks movement of the urethra of a patient during the pelvic pressure pulse; and a computer system in communication with the pressure sensor of the catheter, the computer system being adapted to generate a pressuregram of the relationship between urethral pressure and vesicle pressure in response to changes in pelvic pressure during the pelvic pressure pulse.
Claim 2
Independent Claim
98 words
A system for evaluating female urinary incontinence, comprising: a catheter having at least one pressure sensor positioned thereon; means for supporting the catheter to allow movement of the catheter in response to a pelvic pressure pulse, wherein the movement of the catheter tracks movement of the urethra of a patient during the pelvic pressure pulse; and a computer system in communication with the pressure sensor of the catheter, the computer system being adapted to generate a pressuregram of the relationship between urethral pressure and vesicle pressure in response to changes in pelvic pressure during the pelvic pressure pulse.
Claim 3
Dependent Claim
35 words
The system of claim 1 , wherein the pressure sensing catheter comprises: a catheter positioning surface positioned to engage soft tissues of the urethra so as to inhibit movement of the catheter within the urethra.
Claim 4
Dependent Claim
24 words
The system of claim 2 , wherein the catheter positioning surface comprises: a high friction surface of the catheter for engaging the surrounding urethra.
Claim 5
Dependent Claim
20 words
The system of claim 3 , further comprising: a removable sheath positioned over the high friction surface of the catheter.
Claim 6
Dependent Claim
38 words
The system of claim 1 , wherein the pressure sensing catheter comprises: a balloon positioned to engage soft tissues of the urethra so as to inhibit movement of the catheter within the urethra when the balloon is inflated.
Claim 7
Independent Claim
108 words
A system for evaluating female urinary incontinence, comprising: a catheter having at least one pressure sensor positioned thereon; means for supporting the catheter to allow movement of the catheter in response to a pelvic pressure pulse, wherein the movement of the catheter tracks movement of the urethra of a patient during the pelvic pressure pulse; and a computer system in communication with the pressure sensor of the catheter, the computer system being adapted to generate a pressuregram of the relationship between urethral pressure and vesicle pressure in response to changes in pelvic pressure as the pressure sensor on the catheter is moved through the urethra of a patient.
Claim 8
Independent Claim
108 words
A system for evaluating female urinary incontinence, comprising: a catheter having at least one pressure sensor positioned thereon; means for supporting the catheter to allow movement of the catheter in response to a pelvic pressure pulse, wherein the movement of the catheter tracks movement of the urethra of a patient during the pelvic pressure pulse; and a computer system in communication with the pressure sensor of the catheter, the computer system being adapted to generate a pressuregram of the relationship between urethral pressure and vesicle pressure in response to changes in pelvic pressure as the pressure sensor on the catheter is moved through the urethra of a patient.
Claim 9
Dependent Claim
38 words
The system of claim 1 or 6 , further comprising: a catheter retraction device for withdrawing the catheter to selectively position a pressure sensor on the catheter at each of proximal, mid and distal positions along the urethra.
Claim 10
Dependent Claim
16 words
The system of claim 6 , further comprising: a display terminal adapted to display the pressuregram.
Claim 11
Independent Claim
188 words
A system for evaluating female urinary incontinence, comprising: a catheter having a proximal end and a distal end, the distal end of the catheter insertable distally into a urethra of a patient so that the urethra surrounds the catheter; a urethra engaging surface disposed on the catheter, the urethra engaging surface exposed to engage the surrounding urethra, engagement between the urethra engaging surface of the catheter and the urethra sufficient to effect movement of the catheter in response to movement of the urethra of a patient during a pelvic pressure pulse; a urethral pressure sensor generating signals indicating a pressure at a urethral pressure location along the urethra, the urethral pressure sensor coupled to the catheter so that the pressure location tracks the movement of the urethra during the pressure pulse; a vesicle pressure sensor coupled to the catheter distally of the urethral pressure sensor; and a computer system in communication with the urethral and vesicle pressure sensors of the catheter, the computer system generating a pressuregram of the relationship between urethral pressure and vesicle pressure in response to changes in pelvic pressure during the pelvic pressure pulse.
Claim 12
Independent Claim
188 words
A system for evaluating female urinary incontinence, comprising: a catheter having a proximal end and a distal end, the distal end of the catheter insertable distally into a urethra of a patient so that the urethra surrounds the catheter; a urethra engaging surface disposed on the catheter, the urethra engaging surface exposed to engage the surrounding urethra, engagement between the urethra engaging surface of the catheter and the urethra sufficient to effect movement of the catheter in response to movement of the urethra of a patient during a pelvic pressure pulse; a urethral pressure sensor generating signals indicating a pressure at a urethral pressure location along the urethra, the urethral pressure sensor coupled to the catheter so that the pressure location tracks the movement of the urethra during the pressure pulse; a vesicle pressure sensor coupled to the catheter distally of the urethral pressure sensor; and a computer system in communication with the urethral and vesicle pressure sensors of the catheter, the computer system generating a pressuregram of the relationship between urethral pressure and vesicle pressure in response to changes in pelvic pressure during the pelvic pressure pulse.
Claim 13
Dependent Claim
24 words
The system of claim 9 , wherein the urethral engaging surface comprises a high friction surface of the catheter for engaging the surrounding urethra.
Claim 14
Dependent Claim
35 words
The system of claim 10 , further comprising a removable sheath removably positioned over the high friction surface of the catheter so as to allow automatic insertion and removal of the catheter from the urethra.
