A safety syringe has an inner barrel, an outer barrel and a locking hub. The inner barrel is mounted removably in the outer barrel and has a front opening. The outer barrel has an inner surface and an annular detent formed in the inner surface. The locking hub is mounted on front opening and has a proximal end, a distal end, a needle mounted on the distal end and a flange formed around and protruding from the proximal end. After an injection, the inner barrel is pulled out of the outer barrel and the flange engages the annular detent. When the inner barrel separates from the outer barrel separate, the locking hub with the needle stays inside the outer barrel. The safety syringe has fewer parts so the design is simple. Less medication is wasted because the locking hub is the only component between the inner barrel and the needle.

Disclosed herein is a delivery system for delivering a leadless pacemaker. The delivery system may include a catheter, which may be a guide catheter. The catheter includes a distal end, a proximal end opposite the distal end, a lumen extending between the distal end and the proximal end, and a locking hub operably coupled to the proximal end. The locking hub includes a lumen segment of the lumen. In one implementation, self-biasing of the lumen segment places the lumen segment out of alignment with a rest of the lumen. Deflecting the lumen segment against the self-biasing of the lumen segment places the lumen segment in coaxial alignment with the rest of the lumen. In another implementation, self-biasing of the lumen segment reduces an inner diameter of the lumen segment and actuation of the locking hub expands the inner diameter.
