MiniMed 770G Insulin Pump Battery Cap May Deteriorate, Causing Power Loss

Medtronic is recalling MiniMed 770G insulin pumps because battery cap deterioration may cause power loss and insulin delivery failure. Approximately 123,585 units are affected.

The agency’s classification

FDA (Devices): Class II

Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.

This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work

What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: FDA Class II device recall with no reported hospitalizations or injuries. Battery deterioration in a critical insulin delivery pump creates risk of power loss and harm to users dependent on continuous insulin delivery. Meets rubric criterion: 'risk-of-harm products where injury has not yet been reported.'

Plain-English summary

Medtronic MiniMed is recalling the MiniMed 770G insulin pump (U.S. and overseas versions) due to potential battery cap deterioration. Approximately 123,585 units are affected, involving product models MMT-1880, MMT-1881, MMT-1882, MMT-1890, MMT-1891, and MMT-1892.

Battery cap deterioration may result in an incomplete battery circuit, similar to a detached battery cap, causing loss of power and loss of insulin infusion pump functionality. This compromises the pump's ability to deliver insulin.

The affected pumps were distributed throughout the United States (all 50 states, Washington D.C., Puerto Rico, and the U.S. Virgin Islands) and to overseas locations. Specific affected serial numbers have been identified for recall purposes.
