Blood Testing Instrument

Heart Valve Clip

Pace Maker
Project: Blood Testing Instrument Manufacturer
Problem: Device re-design resulted in issues with the ability to manufacture the key part of the instrument. Existing vendor base would not attempt to manufacture.
Material: Tungsten
Critical Dimensions:

.0070Ø x .87” long in the middle of the part

Hold +.0000/-.0002” tolerance on diameter

Hold +/-.001” tolerance on length of .007”Ø

8 Ra surface finish max
Resolution: A manufacturing process was developed that not only resulted in the ability to make the part, but withstood two part revisions that tightened tolerances to give the device an even higher level of function and reliability.
Grinding discipline(s) that contributed to resolution:
Project: Heart Valve Clip Locking Pin
Problem: The extremely small size of the part, critical to affixing a clip to a defective heart valve, resulted in manufacturing difficulties, and unacceptable inconsistencies in holding the required part tolerances.
Material: Elgiloy
Critical Dimensions:

Center Diameter size - .0191/.0190

OAL: .056’’

8 Ra surface finish

.001” max inside corner radii
Resolution: a manufacturing process was created that yielded 95% success rate. Project was able to move forward into clinical trials and is currently seeking FDA approval.
Grinding discipline(s) that contributed to resolution:
Project: Pace Maker Project
Problem: In a patent race with competitors, this company needed a rapid prototype of a newly designed part. Parts needed to be manufactured complete and shipped in one week.
Material: 304 SST
Critical Dimensions:

Small, detailed relief in middle of part

OAL 5.0"
Resolution: Parts were manufactured in time, but when a shipping SNAFU occurred, and it was evident that the "drop dead" delivery date was going to be compromised, M&S re-acquired the package from the shipping company, put a representative on a plane and
personally flew it to the customer the same day!
