Systems and methods for slitting a delivery device are described. A slitter assembly for slitting the delivery device in accordance with the present disclosure includes a housing, a lock mechanism coupled to the housing, and a clamshell mechanism coupled to the lock mechanism. The clamshell mechanism defines a channel having an adjustable diameter and sized to receive a device. The slitter assembly also includes a blade configured to slit a tubular shaft of the delivery device.

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.

A holder for a prosthetic heart valve includes a base having an annular portion defining an aperture, and a spool rotatably mated with the base. The spool has a platform and a head extending in a longitudinal direction from the platform. The holder further includes a button housing having an aperture sized and shaped to receive the head of the spool, and a button inserted in the button housing. The button housing is detachably coupled to the spool in an assembled condition. The button is movable relative to the button housing to move the button housing from a condition locked to the spool to a condition removable from the spool.

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.

A delivery device for a collapsible heart valve includes an operating handle and a catheter assembly. The operating handle includes a frame defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, and a coupler having locked and unlocked conditions, the coupler being operatively connected to the carriage assembly for movement therewith. The catheter assembly includes a shaft around which a valve-receiving compartment is defined, the shaft being operatively connected to one of the frame or the carriage assembly, and a distal sheath operatively connected to the carriage assembly for movement therewith between a closed condition adapted to maintain the valve in the compartment and an open condition adapted to fully deploy the valve.

Staged deployment devices and methods for transcatheter heart valve delivery

A delivery device for a collapsible prosthetic heart valve includes an operating handle and a catheter assembly. The operating handle may include a housing defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, a deployment actuator coupled to the housing and rotatable relative to the housing, and a coupling assembly rotationally fixed to the deployment actuator. The catheter assembly may include a first shaft around which a compartment is defined and a distal sheath operatively connected to the carriage assembly. Movement of the carriage assembly in the longitudinal direction in the movement space may move the distal sheath between the closed condition and the open condition. The coupling assembly may have an engaged position in which rotation of the deployment actuator moves the carriage assembly, and a disengaged position in which rotation of the deployment actuator does not move the carriage assembly.

Devices and methods for transcatheter heart valve delivery

In a catheter system and method for assembly thereof, one end of a catheter shaft is inserted into a connector for a handle, with the connector being generally tubular and having a channel extending longitudinally therethrough. At least a lengthwise segment of the channel is sized in transverse cross-section greater than an outer cross-section of the catheter shaft. The catheter shaft is inserted into the channel of the connector such that the catheter shaft is spaced from the connector within the lengthwise segment of the channel. Adhesive is directed through a port in the sidewall of the connector into the lengthwise segment of the channel to flow circumferentially about the catheter shaft within the channel. The adhesive is allowed to cure and the connector (with the catheter adhered thereto) is retained on the handle.

Catheter system

A catheter assembly comprising a catheter handle () with a collet () disposed at a distal end. The collet is coupled to a strain relief () comprising a nut () and a strain relief projection (). The collet comprises at least one leaflet () and at least one collet spur (), and the nut comprises at least one ratchet (). The collet is configured to couple to the nut, and the at least one ratchet is configured to interact with the at least one collet spur to securely fasten the strain relief to the catheter handle. The at least one leaflet is configured to couple to a catheter shaft.

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.
