FIELD

The present disclosure relates to methods and systems for performing medical procedures on anatomical structures of a body. Such medical procedures may include, for example, attenuating transient pressure waves in the anatomy of the body, for example, by implanting a pressure attenuating device in the anatomy of the body subject to such pressure waves.

Description of the related Art

Pressure waves are known to propagate through incompressible fluids in various anatomical structures of the body. These pressure waves may be caused by events that normally occur in the body, such as the beating of the heart, breathing in the lungs, peristaltic action in the gastrointestinal tract, and movement of body muscles. Alternatively, these pressure waves may be caused by sudden events, such as coughing, laughing, external trauma to the body, and movement of the body relative to gravity. The propagation of these pressure waves increases as the elasticity (sometimes called compliance) of the surrounding tissues and organs decreases. These pressure waves have many undesirable effects, from discomfort of pressure on organs and tissues, to fluid leakage, to renal failure, to stroke, to heart attack, to blindness.

Urinary tract disorders, such as urinary frequency, urgency, incontinence and cystitis, are a common problem in the united states and even worldwide, affecting people of all ages both physiologically and psychologically. Urine is composed primarily of water and is an incompressible fluid in nature in the typical pressure ranges found in the human bladder. The maximum urethral pressure for normal bladder urination is clearly related to the intravesical pressure. During normal urination, urethral relaxation occurs before detrusor contraction causes intravesical pressure to exceed urethral pressure.

The peak intravesical pressure is typically caused by volumetric tissue displacement in response to gravity, muscle activity, or rapid acceleration. The lack of compliance of the bladder and the urine contained therein with respect to high frequency, high intensity and short wavelength events results in minimal fluid pressure attenuation of the high frequency pressure waves and results in high intravesical pressures being transmitted directly to the bladder neck and urethra, which may or may not cause detrusor contraction. In these cases, the urethra may act as a volume pressure relief mechanism, allowing a proportional volume of fluid to escape (escape) the bladder, thereby reducing the intravesical pressure to a tolerable level. The urethra has a maximum urethral pressure value and when the intravesical pressure exceeds the maximum urethral pressure, fluid will overflow the bladder. In these cases, neuroreceptors in the bladder and/or bladder neck and/or trigone trigger detrusor contractions, which can result in voiding (urinary frequency) or can resolve without voiding (urgency) or can result in intravesical pressure exceeding the maximum urethral pressure, resulting in fluid overflow of the bladder (stress incontinence).

For most patients with problems with urinary tract disorders (e.g., frequency, urgency, stress and urge incontinence and cystitis), the cause and/or contributor to bladder dysfunction is a decrease in overall dynamic bladder compliance as opposed to a decrease in steady-state bladder compliance. These patients may typically have a bladder that is compliant under steady state conditions, but becomes non-dynamically compliant when subjected to an external pressure event having a short duration, e.g., less than 5 seconds, or in some cases less than 0.5 seconds. The decrease in dynamic compliance of the bladder is often caused by aging, use, distension, childbirth, and trauma. In addition, the anatomy of the bladder relative to the diaphragm, stomach, and uterus (for women) causes external pressure to be exerted on the bladder during athletic activities such as speaking, walking, laughing, sitting, moving, rolling, and rolling. For patients with stress incontinence due to lack of dynamic compliance in the bladder, leakage occurs when intravesical pressure exceeds the maximum urethral pressure.

In view of the above, many attempts have been made to combat urinary tract disorders. One such attempt has been to implant a compressible pressure attenuating device in the bladder to reduce the intravesical pressure. This method is disclosed, for example, in the following documents, all of which are incorporated herein by reference: U.S. patent No. 6,682,473, Matsuura et al, published 2004, 1/27; U.S. patent No. 7,074,178, Connors et al, published 2006, 7/11; and U.S. patent application publication No. 2010/0222802; gillespie, jr. et al, published 9/2/2010. In accordance with one aspect of the foregoing method, a compressible device is inserted in a compressed state through a patient's urethra into a patient's bladder, and then, once in the bladder, the compressible device is expanded, for example, by inflating with atmospheric air. The delivery system may be used to deliver the compressible device through the urethra and into the bladder, and may also be used to expand the compressible device from its compressed state to its expanded state and deploy the compressible device from the delivery system once expanded. If removal or replacement of the compressible device is desired, the compressible device can be removed from the bladder through the urethra using a removal system.
