Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If current medical devices are used for vascular interventions, then the procedures can be performed with existing technology, but the devices lack capability for minimally invasive, reliable, and widely applicable excisional and interventional procedures

Engineering Contradiction:

Improvecapability for minimally invasive, reliable, and widely applicable excisional and interventional proceduresVSAvoidreliability in addressing acute and chronic total vessel occlusions

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The excisional device is designed with multiple functional components including a work element for tissue removal, imaging capabilities for visualization, and delivery mechanisms for therapeutic agents. This multi-functional design allows a single device to perform excision, imaging, and therapeutic delivery, resolving the contradiction by providing both versatility in procedure types and reliability through integrated functional components that work together systematically

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device employs a nested structure where the work element is positioned within a delivery catheter, which itself is nested within larger vascular access components. This nested architecture enables minimally invasive insertion through small access points while maintaining the reliability of robust excisional and therapeutic capabilities once deployed at the target site

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If traditional vascular intervention devices are used, then the device structure can be simple, but they lack integrated imaging capabilities and excisional functionality

Engineering Contradiction:

Improveintegrated imaging and excisional capabilitiesVSAvoiddevice structure with multiple integrated components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges previously separate functions (imaging, excision, and therapeutic delivery) into a single integrated device. The imaging component, work element for excision, and delivery mechanisms are combined in one apparatus, allowing simultaneous or coordinated performance of multiple functions. This resolves the contradiction by achieving high adaptability through integration while managing complexity through unified design rather than multiple separate devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device is segmented into distinct functional modules including an imaging module, a work element module for excision, and a delivery module for therapeutic agents. Each module can be independently optimized and controlled, allowing the complex integrated device to maintain versatility while managing structural complexity through modular architecture that enables independent functionality of each component

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If minimally invasive procedures are performed, then patient trauma is reduced, but the capability to reliably remove occlusions and restore vascular channels is limited

Engineering Contradiction:

Improveminimally invasive procedure capabilityVSAvoidefficiency in removal of occlusions and restoration of vascular channels

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The device replaces traditional large-scale mechanical open surgery with a minimally invasive approach using a catheter-based excisional device that can be inserted through small access points. The work element performs excision of occlusions through the catheter, and imaging capabilities guide the procedure, maintaining high productivity in clearing occlusions while achieving minimally invasive benefits of reduced patient trauma and faster recovery

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A platform device for material excision or removal from vascular structures for either handheld or stereotactic table or robotics platform use may comprise a work element or elements configured to selectively open and close at least one articulable beak or scoopula configured to penetrate and remove intra-vascular materials or obstructions, or follow a central lumen of another device or over a wire in a longitudinal direction. A telescoping set of inner and outer tube axially actuated together and to actuate a beak set, axially actuated differentially, whether controlled mechanically or electronically may be combined with an outer tubular sheath, which may be full circumference or partial circumference along its length, to form a system for rotational non-sharp dissection, coring, severing off, transporting or in the reverse, depositing various fluids and solids for a variety of clinical uses.
