Abstract: A catheter device for repositioning or explanting an implantable medical device comprises an outer catheter, and a steerable catheter extending through the outer catheter, wherein the outer catheter is axially movable with respect to the steerable catheter. A snare catheter extends through the steerable catheter, wherein the snare catheter is axially movable relative to the steerable catheter. A mandrel may extend through the snare catheter and comprising a distal end, wherein the mandrel is axially movable relative to the snare catheter. A snare may be arranged on the distal end of the mandrel for establishing a connection to the implantable medical device, wherein the snare, by moving the mandrel with respect to the snare catheter, is at least partially retractable into the snare catheter.

Abstract: A control handle for controlling functions of a delivery system for implanting a medical device is described. The delivery system comprises an elongate delivery catheter and a mandrel being displaceable longitudinally relative to the delivery catheter. The control handle comprises a slider mechanism and a handle housing. The slider mechanism is configured for being displaceable in a longitudinal direction relative to the handle housing between a fully undeployed position and a fully deployed position such as to thereby displacing the mandrel relative to the delivery catheter by a deployment distance.

Abstract: A control handle for controlling functions of a delivery system for implanting a medical device is described. The delivery system comprises an elongate delivery catheter and a mandrel being displaceable longitudinally relative to the delivery catheter. The control handle comprises a locking mechanism and a handle housing. The locking mechanism is configured for being switchable between a locked configuration and an unlocked configuration such that, in the locked configuration, the mandrel is fixed relative to the locking mechanism such that the mandrel is not displaceable relative to the locking mechanism beyond a predetermined abutment position due to a mechanical mandrel abutment blockage, whereas, in the unlocked configuration, the mandrel is movable in the longitudinal direction relative to the locking mechanism beyond the predetermined abutment position due to the mandrel abutment blockage being released.

Abstract: A delivery system for implanting a medical device comprises a delivery catheter having an inner lumen, a mandrel received in the inner lumen of the delivery catheter and movable with respect to the delivery catheter, and an adapter piece connected to the mandrel, wherein the adapter piece, by moving the mandrel with respect to the delivery catheter, is displaceable between a first position in which the adapter piece is received within the inner lumen of the delivery catheter and a second position in which the adapter piece is arranged outside of the inner lumen of the delivery catheter. A tethering member comprises a positive-locking member adjoining a tether portion, wherein the positive-locking member in a connection state is received on the adapter piece, but is releasable from the adapter piece by displacing the adapter piece from the first position towards the second position.

Abstract: A catheter device for implanting a medical device comprises a steerable catheter, and a delivery catheter extending through the steerable catheter and being configured to interact with the medical device for implanting the medical device at an implantation site within a patient, wherein the delivery catheter is axially movable with respect to the steerable catheter. The steerable catheter comprises a first steering articulation zone and a second steering articulation zone arranged distally with respect to the first steering articulation zone, wherein the steerable catheter is steerable by a deflection in the first steering articulation zone and the second steering articulation zone.

Abstract: An implantable medical device includes a housing having a proximal end and a distal end. The implantable medical device is placeable on cardiac tissue in the region of the distal end. An anchoring device is fixedly attached to the housing in the region of the distal end. The anchoring device includes at least one anchoring member. The at least one anchoring member includes a first end and a second end opposite the first end. The second end is disposed on the housing. The at least one anchoring member longitudinally extends between the first end and the second end along an axis of extension and is formed by a flat strip which is twisted by a twist angle about the axis of extension between the first end and the second end. A method for manufacturing an implantable medical device is also provided.

Abstract: A catheter system for explanting an intracardiac medical device, comprising: a catheter having a distal catheter tip configured to surround the intracardiac medical device and an encapsulation tissue that has grown around the intracardiac medical device, and a deployable cutting element at the distal catheter tip.
