Abstract: 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.

Abstract: A device for temporarily securing a rolling assembly such as a shopping cart or children's stroller is disclosed. A support base is affixed to a surface such as automobile trunk interior or passenger compartment. A stabilizing arm is adjustably connected to the support base and includes attachment means on a distal end. A user extends the stabilizing arm such that attachment means is proximal the rolling assembly and temporarily connects the attachment means to the rolling assembly. In this manner, the rolling assembly is temporarily stabilized during loading or unloading to prevent unwanted movement.
