Urinary Bladder TRIZ Cases

Steerable tubular members and an atraumatic distal end enable precise prostatic urethral implant placement through tortuous anatomy.

Steerable segmented delivery enables accurate prostatic urethral implant placement through tortuous anatomy while limiting tissue trauma.

A multi-tube implant delivery approach improves placement accuracy in the prostatic urethra while navigating tortuous anatomy with less tissue trauma.

Multiple tubular members and proximal control improve implant placement in the prostatic urethra while minimizing tissue trauma.

Independent tubular segments and proximal control improve implant placement in tortuous prostatic urethras while limiting tissue trauma.

A multi-tube delivery system enables steerable, accurate implant release in the prostatic urethra while limiting tissue trauma.

Nested tubular delivery components navigate tortuous prostatic urethral anatomy for precise implant deployment with low tissue trauma and retrieval.

A tubular implant supports the bladder-urethra junction and extends effective urethral length to reduce post-prostatectomy incontinence.

A foil-sealed hydrating sleeve keeps the catheter coating wet and sterile, reducing contamination risk when water is unavailable.

A subcutaneous pump and internal urine container restore urethral urination timing while reducing complications of intestinal neobladder surgery.

Manual chamber expansion and compression create pressure-driven fluid transfer from the abdominal cavity to the bladder.

An abdominal collection container, subcutaneous pump, valves, and cleaning port support controlled urination and stone prevention.

This case uses side-entry vascular servovalves to divert blood without interrupting circulation, reducing ischemia during graft transfer.

Biodegradable scaffolds seeded with autologous smooth muscle cells regenerate urinary-like tissue layers.

An access sheath with a tubular frame and embedded wire reinforcement prevents kinking while preserving working channel area for ureteral procedures.

Seeding scaffolds with non-autologous smooth muscle cells eliminates immunosuppressive therapy requirements while enabling luminal organ regeneration.

A perfluorocarbon-filled bladder implant absorbs transient intravesical pressure spikes, preventing urine leakage and discomfort.

Hydrodynamic valve opens at 750 mm H2O to allow urine flow while remaining closed during spike pressures, improving patient quality of life.

A percutaneous urinary catheter deploys a retention portion in the renal pelvis to establish an outer protective surface area.

A PGA patch with a star-shaped copolymer frame prevents urine leakage and collapse during tissue regeneration.

Acellular extracellular matrix cardiovascular prostheses reduce thrombosis and intimal hyperplasia while promoting site-specific tissue regeneration.

A segmented ureteral stent uses a rigid proximal portion for insertion and a flexible distal portion with capillary wicking to move fluid.

Neuroprosthetic system decodes electrophysiological signals from the unaffected brain hemisphere to control ipsilateral body parts.

Nonwoven biomaterial scaffolds eliminate metabolic complications and lengthy cell culture processes while restoring bladder capacity.

A predictive control system dynamically adjusts urethral compression based on patient activity to prevent urinary leakage.

Replacing non-resorbable materials with resorbable PGA and PLA polymers eliminates bacterial reservoirs while maintaining structural stability during healing.
