The SAM IO utilizes a multi-use and manually powered driver for efficient and controlled IO access. The driver is cleanable and tested to hundreds of actuations, while the manual operation eliminates battery-related failure and reduces the weight of the driver.
The driver functions through a passive ratcheting mechanism which causes the needle to only rotate clockwise when resistance is encountered. Through actuation of the driver handle, the user provides controlled insertion of the IO needle with a tactile feel of cortical penetration.
