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 valve bypass tool, and a biostimulator transport system having such a valve bypass tool, is described. The valve bypass tool includes an annular seal to seal against a protective sheath of the biostimulator transport system. The valve bypass tool is slidably mounted on the protective sheath and includes a bypass sheath to insert into an access introducer. The valve bypass tool can lock onto the access introducer by mating a locking tab of the valve bypass tool with a locking groove of the access introducer. The locking tab can have a detent that securely fastens the components to resist decoupling when the biostimulator transport system is advanced through the access introducer into a patient anatomy. Other embodiments are also described and claimed.

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.

The valve bypass tool includes an annular seal to seal against a protective sheath of the biostimulator transport system. The valve bypass tool is slidably mounted on the protective sheath and includes a bypass sheath to insert into an access introducer. The valve bypass tool can lock onto the access introducer by mating a locking tab of the valve bypass tool with a locking groove of the access introducer. The locking tab can have a decent that securely fastens the components to resist decoupling when the biostimulator transport system is advanced through the access introducer into a patient anatomy. Other embodiments are also described and claimed.

A vascular closure assembly includes a suture placement device and a sealant delivery device. The suture placement device is operable to position at least one suture across the puncture to form a primary seal of the puncture. The sealant delivery device includes a sealant delivery tube having a first lumen sized to receive the at least one suture, and a second lumen configured to deliver a volume of sealant to the puncture after forming the primary seal to create a secondary seal of the puncture. The sealant delivery device is slidable along the at least one suture to the puncture.
