A delivery device for an implantable medical device may include an inner shaft configured to retain the implantable medical device at its distal end, an outer shaft slidably disposed about the inner shaft, and a locking hub affixed to the outer shaft. The locking hub may include a housing, a piston element in the housing, an actuator operatively coupled to the piston element, and a clamping gasket made of a compressible material and disposed in the housing. The actuator may be movable relative to the housing between unlocked and locked conditions. The clamping gasket may have a lumen defining a first diameter with the actuator in the unlocked condition and a second diameter with the actuator in the locked condition, the second diameter being less than the first diameter. The outer shaft and the locking hub may be fixed to the inner shaft with the actuator in the locked condition.

Locking guide catheter hubs

A delivery deviceincludes a catheter assemblyand an operating handle. The operating handlemay include a noseaffixed to the catheter assembly, an axial shaft, a basetranslationally fixed to a proximal end of the axial shaft, a screwhaving external threads and a non-circular lumen, the axial shaft extending through the non-circular lumen, a proximal endof a pull wirebeing affixed to the screw, a knobhaving internal threads engaged with the external threads of the screw, and a collarextending at least partially around the axial shaft. When the collaris in a proximal position, rotation of the knobmay deflect the distal endof the catheter assembly. When the collar is in a distal position, rotation of the knobmay rotate the catheter assembly

Operating handle for selective deflection or rotation of a catheter

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.

Catheter-based delivery system for delivering a leadless pacemaker and employing a locking hub

Catheter-based delivery systems for delivery and retrieval of a leadless pacemaker include features to facilitate improved manipulation of the catheter and improved capture and docking functionality of leadless pacemakers. Such functionality includes mechanisms directed to deflecting and locking a deflectable catheter, maintaining tension on a retrieval feature, protection from anti-rotation, and improved docking cap and drive gear assemblies.
