Balloon Catheter TRIZ Cases

Segmented revascularization strategy uses venous arterialization to treat diffuse coronary disease where conventional forward-flow techniques fail.

Segmented catheter modules merge into a unified assembly via a mechanical locking interface, reducing procedural time while maintaining treatment versatility.

Inflatable balloon cuffs on a fistula device form a fluid seal against bowel walls, preventing enteric leakage and reducing nutritional losses.

Balloon catheters visualize the internal thoracic vein to position electrodes closer to the heart, reducing defibrillation energy and pulse generator size.

Segmenting the anchoring platform and valve support reduces delivery diameter while maintaining structural strength at the implant site.

Elongate member coated with hemostatic material and covered by a removable barrier deploys through percutaneous sheaths to promote clot formation.

Embedding a spring in viscoelastic polymer expands both materials to apply uniform force on the plunger, resolving bulkiness in conventional mechanical pumps.

Segmented compartments prevent vessel wall trauma and dissections during angioplasty.

A deployable balloon occludes puncture sites to prevent hematoma formation during sealing compound injection.

Cobalt chromium frame and nitinol paddles overcome calcific tissue resistance to prevent embolization in mitral stenosis.

A catheter impeller with a toroidal balloon funnels blood flow to create a Venturi effect at the lymphatic outlet.

Dual balloons form a sealed chamber to isolate blood flow, allowing precise chemical delivery that reduces nerve damage risks.

Rotating a barrel inside a cup-shaped port body selects fluid paths for bladder irrigation and drainage while maintaining a closed sterile system.

Segmented shaft flexibility improves lesion access in bent vessels while maintaining torque transmissibility.

A support structure frictionally engages native leaflets to anchor a prosthetic valve, preventing annulus dilation during implantation.

An enterostomy tube anchors via an internal balloon to drain liquid stool, preventing leakage and peristomal skin damage.

A swallowable capsule deploys needles to inject therapeutic agents directly into intestinal submucosal tissue.

Segmented fixation within mesh wire spaces reduces stress concentration and prevents breakage during radial expansion.

Segmented shaft with varying stiffness and dual balloons prevents slippage while navigating tortuous coronary anatomy.

A variable extrusion die forms alternating inflation lumen sections in continuous inner tubes.

Dual-side rotation prevents twisting during coating, maintaining position stability for controlled drug morphological form and release.

Fluid-driven balloons bend a catheter segment to engage lumen walls, eliminating pull-wire hysteresis and improving articulation reliability.

A volume adaptor modulates intracranial pressure by expanding and shrinking in sync with the cardiac cycle to enhance cerebral blood flow.

Balloon actuation transitions prosthetic member configurations to eliminate pushing wire resistance and coupling asymmetry in valve repair instruments.

Gripping system integrates illuminating guidewire and seeker portions to position balloon catheters within sinus cavities.

Nested balloon catheters occlude venous flow to reduce preload and stimulate the vagus nerve, improving cardiac remodeling.

An evacuated flexible receiver laminates medical balloons without fixed dies, ensuring uniform layer contact.

A beveled aspiration catheter with a blocking element prevents device inversion during clot fragmentation.

A urinary catheter uses a separate connection tube to link the inflation opening with the balloon interior.

A pivoting mechanical linkage connects an actuator to a syringe plunger for single-handed insufflation.
