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 biostimulator transport system, such as a biostimulator delivery system, is described. The biostimulator transport system includes a flexible tether extending through a tether support to a tether bight. The tether bight loops through an attachment feature of a biostimulator to connect the biostimulator to the biostimulator transport system. Tether legs extend from the tether bight to a handle of the biostimulator transport system. The handle includes a housing and a knob, and the tether legs attach to the housing and the knob. A tether leg can be disconnected from the housing and the knob can be removed to pull the tether out of the attachment feature and release the biostimulator from the biostimulator transport system. Other embodiments are also described and claimed.

Abstract: A biostimulator delivery system having a tether cable, is described. A connector can be mounted on the tether cable to connect to a biostimulator. The connector can be a protuberance that lodges within the biostimulator, or a threaded connector that screws into the biostimulator. The tether cable has a stranded cable configuration, including several strands extending about a core strand in a helical direction. The stranded cable structure resists breaking under bending stresses typically seen during a tether mode used during delivery of the biostimulator. The tether cable reliably secures the biostimulator to the delivery system in the tether mode. Other embodiments are also described and claimed.

Abstract: A delivery device 100 includes a catheter assembly 120 and an operating handle 130. The operating handle 130 may include a nose 131 affixed to the catheter assembly 120, an axial shaft 180, a base 132 translationally fixed to a proximal end of the axial shaft, a screw 160 having external threads and a non-circular lumen 161, the axial shaft extending through the non-circular lumen, a proximal end 171 of a pull wire 170 being affixed to the screw, a knob 150 having internal threads engaged with the external threads of the screw, and a collar 140 extending at least partially around the axial shaft. When the collar 140 is in a proximal position, rotation of the knob 150 may deflect the distal end 121 of the catheter assembly 120. When the collar is in a distal position, rotation of the knob 150 may rotate the catheter assembly 120.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods for providing a dock that extends the utility of an electronic device are provided. In some embodiments, responsive to detecting an electronic device, a dock may cause an establishment of a connection between the dock and the electronic device. The dock may obtain one or more interface requirements for the electronic device that enable the dock to interact with the electronic device. The dock may obtain, via the established connection, based on the interface requirements, a request from an application of the electronic device for content stored at a source external to the dock and the electronic device. The dock may cause the requested content to be presented via at least one of the output devices responsive to obtaining the requested content from the external source.
