| APPLICATION |
Medical (Sutured Mediated Vascular Closure System)
|
|
|
This device permits a suture inside a sheath to be inserted into an artery and then deploys twin needles which pierce the artery wall and capture the suture thereby permitting a consistent subcutaneous knot to be tied.
|
OUR APPROACH |
Our customer needed to hold relative position within .002 between the tips of (2) two .020 diameter needles
| captured in plastic. This had been achieved with the use of a microscope during the prototyping phase, however, the challenge for MIE was to develop an effective method to reliably achieve this in high volume production. Once molded, the needle tips could not be allowed to come in contact with each other or any outside materials. MIE was able to develop a |
|
 |
solution to high volume manufacturing and a packaging solution which protected the needles after molding until ready for final assembly at our customer
MATERIALS |
- Needle: 304 Stainless
- Molding Material: RFL 4036 Nylon w / PTFE
|
| RESULTS |
- Achieved high volume solution which adequately maintained critical tip to tip position.
- Developed packaging solution to protect parts until use.
- Product reduced patient ambulation time from 8 to 10 hours to 2 hours.
- Eliminated need to apply excessive pressure on sore areas and thereby reduced patient discomfort while hemostatis occurs
