DIRECT DEPLOYMENT SYSTEM AND METHOD Russian patent published in 2017 - IPC A61B5/215 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment, namely to system and method for direct deployment and implantation of a device to monitor physiological conditions e.g., of the body including, for example, the pressures inside the portal and hepatic veins. Deployment system for deploying an implantable device, comprising a cannula a pushrod, a controlled deployment mechanism, and said implantable device. Implantable device is attached to the controlled deployment mechanism with a possibility of detachment. Pushrod, the controlled deployment mechanism and said implantable device are contained within the cannula Controlled deployment mechanism has a negative force limit and is located at the distal end of the pushrod, and it is made with a possibility of controllable detachment of implantable device when the negative force limit is achieved - during the backdriving of pushrod. Method of deployment the implantable device into the target location using the above system of deployment includes the steps according to which the system is advanced to the target location apply an adjustable amount of force release of the implantable device from a controlled deployment mechanism, thus securing the implantable device in the target location and removing the pushrod and a cannula. In the second option method of deployment the implantable device into the target location using the above system of deployment includes the steps according to which the system is advanced to the target location apply amount of force to secure the implantable device at the target location, apply amount of force to provide reliable fixation of the implantable device, detach the implantable device out of the controlled deployment mechanism and remove the pushrod and a cannula.

EFFECT: use of the invention allows to provide safer access thanks to a smaller diameter of punctures, additional spaces for implantation, reduced procedure time and increased availability of implantation spaces.
