A needle deployment device is provided. The needle deployment device comprises a body, a plurality of medical needles displaceably mounted on the body and an actuator on the body. The actuator is actuatable in response to pressurizing a fluid so as to cause the needles to displace relative to the body. It has been found that the device can be used advantageously as a suture placement device for placing suture elements through walls of vessels, and the like, during, for example, coronary artery bypass graft (CABG)surgery, or the like. Furthermore, a medical system comprising at least two bodies, a plurality of needles displaceably mounted on each body and an actuator on each body is provided. Each actuator is selectively actuatable in response to pressurizing a fluid so as to cause the needles to be displaced relative to their associated bodies. A method of performing a medical procedure is also provided. The method comprises pressurizing a fluid, actuating an actuator of a needle deployment device in response to pressurizing the fluid and causing a plurality of needles to displace in response to actuating the actuator.
