An introducer hub assembly, such as an introducer hub assembly of a leadless cardiac pacemaker, including a hemostatic seal having a cross-slit configuration, is described. The hemostatic seal can be retained between a hub cap and an introducer hub. The hemostatic seal includes a first section having first slits intersecting along a longitudinal axis of the introducer hub, and a second section having second slits intersecting along the longitudinal axis. The first slits are angularly offset relative to the second slits to reduce a likelihood that fluid will leak directly through the seal. Other embodiments are also described and claimed.

A medical tool includes a rotation mechanism that further includes a warning feature. The warning feature provides an indication when the rotation mechanism has achieved a number of rotations.

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.

Catheter-based system for delivery and retrieval of a leadless pacemaker

A loading tool for loading a biostimulator onto a biostimulator delivery system is described. The loading tool includes a first body portion and a second body portion connected by a hinge. A latch is mounted on the first body portion, and the latch can be locked to fasten the first body portion to the second body portion. A biostimulator can be mounted in the loading tool, and a tether of a biostimulator delivery system can be inserted through a funnel in the loading tool to engage the biostimulator. An operator can use only one hand to unlock the latch, open the loading tool, and remove the loading tool from the biostimulator prior to delivering the biostimulator into a patient. Other embodiments are also described and claimed.

Loading tool for a biostimulator

A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.

Leadless pacemaker having attachment feature

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.

Leadless biostimulator attachment feature

A catheter assembly includes an inner liner made of flexible material and an outer layer having a steering mechanism. A catheter assembly is provided that includes an inner liner made of flexible material, and an outer layer having a steering mechanism that includes at least one wire and a corresponding lumen for each of the at least one wire through which the respective wire may travel. The outer layer includes a braided wire assembly that includes at least two wires braided into a wire mesh, and further includes a see-through portion positioned proximate a pull wire extraction location to facilitate extraction.
