Caliper Handle (IP in review)
Previous Prototype
Redesigned Prototype
Project/Role:
Took the lead on a new product development project with the goal to create a device to aid physician control during a particularly difficult procedure. A previous employee created an initial prototype of a caliper handle design concept which needed to be pushed forward past the first iteration.
Action:
Determined problem areas within the design that required improvement:
-
The lever was driving a small OD stranded wire in an arc (1). This made for inconsistent, and often ineffective actuation.
-
The lever itself was not made ergonomically (2).
-
Initial design made assembly of the full system difficult, and making modifications impossible.
Redesigned handle addressing problem areas:
-
Designed sliding mechanism to keep actuation of the wire linear(2).
-
Redesigned the lever to resemble bike brake caliper to more effectively fit hand contours. (1)
-
Introduced new parts/subassemblies increasing device modularity, and making assembly/disassembly process seamless.
Result:
Designed and 3D printed multiple iterations of 5 different handle concepts that all serve different purposes and needs. Conducted 2 successful ex-vivo lab studies that demonstrated the functionality of the product. The handle will now be demoed by physicians in the forthcoming year to determine the effectiveness of the design.
Consisent Wall Thickness/Coring
Annular Snap Fit
Ribbing Concepts
Basic Draft Angle Concept
Design for Injection Molding 101
Project/Role:
Boston Scientific's Design for Manufacturability conference needed a reference that encompasses basic design for injection molding principles.
Action:
Consulted expert coworkers, as well as literature and online sources in order to get a strong understanding of the general concepts that go into injection molding. Then compiled all gathered information into a presentation covering injection molding design challenges such as wall thickness and coring, draft angles, ribs, holes and grooves, snap fits, etc.
Result:
Resulting slides were presented at the conference by supervisor, and will be a reference and teaching aide for many BSC employees in the future.
Test Fixture Design
Full Fixture Assembly
Nest Fixture Drawing
Project/Role:
Needed to evaluate BSC hemostasis clipping device in comparison to a competitor’s, but there was no drawing containing the dimensions of the competitor's component that needs to be firmly contained in a 'nest' fixture.
Action:
Identified the critical features and dimensions of the competitor’s device, and designed a simple fixture that can be easily machined from readily available material. Also, designed a simple supplementary system in order for the 'nest' fixture to be attached to a tensile testing system.
Results:
Successfully created the fixturing to secure the competitor’s device, completed the testing, and the data is being used to support a physician drafted publication.
Project/Role:
Company wide 8th annual 'Innovation Challenge'. Problem statement: Come up with a novel solution to aid in the complications that arise with gastric bypass surgery. Specifically, leaking that forms in the new stapled/stitched stomach wall.
​
Action:
-
Work with a group of colleagues of various experience levels and backgrounds to identify possible solutions.
-
Submit all viable solutions as invention disclosures
-
Pick one solution to develop further, identify critical design elements, and create rough prototypes
-
Personally presented the groups solution to Boston Scientific R&D group and management
Results:
Selected as the winner of the innovation challenge among 10 competitors. Instructed to continue development of the product, and complete the patent application process. Awarded patent No. 10,568,754.
