Crux Multiple Core Biopsy Device


To create a prototype device to enhance quality, yield, and speed of gastrointestinal biopsy collection

Anticipated Impact: 

Improved diagnosis of gastrointestinal disorders


There have been no substantive innovations in endoscopic biopsy devices in nearly 40 years. Notably, current gastrointestinal (GI) biopsy forceps are associated with issues such as damage to the collected specimens and sampling inefficiencies. Crux Medical Innovations seeks to develop the Multiple Core Biopsy device to enhance quality, yield, and speed of GI biopsy collection, with the goal of improving disease diagnosis. Target customers are hospitals and physicians in the GI endoscopy market. This grant will support prototype design, fabrication, and testing. Crux anticipates that having a functional prototype will help secure funding for further development.

Grant Update

Principal Investigator:
Bob Clements
Grantee Organization:
Crux Medical Innovations
Grant Title:
Crux Multiple Core Biopsy Device
Grant Cohort and Year:
2012 Proof of Concept (04)
Grant Period:
01/28/2013 - 01/27/2015 (Completed)
Grant Amount:
With the LSDF Proof of Concept Grant, Crux was able to cross the valley of death emerging with an improved functional design & engineered device. While the micro-manufacturing and blade assembly posed challenges a successful MCB prototype device was built and tested resulting in a positive Proof of Concept. The MCB's distal cutting mechanism performed as designed enabling Crux Medical to move into Phase 2 intended to include full length prototype ans live animal studies.
