Abstract: A delivery device, a cardiac pacing device and a fixation structure are disclosed. The fixation structure includes a casing, a driving member and an elastic member. The casing has a first internal cavity and a slot, and the driving member is partially received in the first internal cavity in such a manner that one end of the driving member protrudes out of the first internal cavity from a proximal end thereof and is detachably connected to the driving sheath. The elastic member is accommodated in the first internal cavity in such a manner that its one end is coupled to the driving member and the other end extends outwardly from the driving member and is inserted in the slot. The driving member is configured for fitted connection with the casing while being able to move in an axial direction of the casing to drive the elastic member to move in the slot, thereby causing the elastic member to protrude out of or move back into the slot.

Abstract: A leadless pacemaker (100, 200, 300) and trailing (1, 3, 5) and leading (2, 4, 6) components thereof are disclosed. The trailing component (1, 3, 5) includes a first connecting member (12, 32) and a second connecting member (13), and the leading component (2, 4, 6) includes a third connecting member (23, 42, 62) and a fourth connecting member (24, 63). The first connecting member (12, 32) is configured to be detachably connected to the third connecting member (23, 42, 62) and the second connecting member (13) is configured to be detachably or non-detachably connected to the fourth connecting member (24, 63), thereby achieving interlocking between the trailing component (1, 3, 5) and the leading component (2, 4, 6). Additionally, both the first connecting member (12, 32) and the third connecting member (23, 42, 62) are non-biodegradable.

Abstract: A leadless pacemaker, a leading component, a trailing component and a delivery device are disclosed. The leading component (10) includes a leading end body (100), a first connection member (101) and a second connection member (102). The trailing component (20) includes a trailing end body (200), a third connection member (203) and a fourth connection member (204).

Abstract: A cardiac pacing system and a pacemaker fixation device are disclosed. The pacemaker fixation device includes a ring-shaped stent and at least one contractible member. The ring-shaped stent is configured to load a leadless pacemaker and easily fix it at a target site in a patient's body reliably without dislodgement. A connecting element in the contractible member can be reliably connected to an external mechanism, thus facilitating retrieval and removal of the cardiac pacing system with an increased success rate. During implantation, the contractible member can be adapted by operating the external mechanism to adjust the pacing location for the leadless pacemaker, thus allowing the operator to easily determine the best pacing location that can result in enhanced pacing performance of the leadless pacemaker. Further, the leadless pacemaker may be fixed in the atrium in order to pace the atrium, thus reducing non-physiological pacing with atrioventricular desynchronization.

Abstract: An active cardiac electrical lead is disclosed, including a tip housing having a lumen, a soft tip plug and a marker band. The tip housing includes a body and an extension extending from a distal end of the body, and the body is of greater outer diameter than the extension. The soft tip plug fits over the extension and engaging the extension. The marker band is attached to an outer surface of the body or to an inner surface of the lumen.

Abstract: An implantable medical lead is disclosed herein. In one embodiment, the lead includes a body, at least one electrode and a lead connector end. The body includes a distal portion and a proximal portion. The at least one electrode is on the distal portion. The lead connector end is on the proximal portion and includes a pin contact and a retainer assembly. The pin contact is electrically coupled to the at least one electrode and proximally extends from the lead connector end. The retainer assembly retains the pin contact as part of the lead connector end and includes a collar and a cap. The cap is secured within the collar via an interference fit arrangement and includes a hole through which the pin contact extends.

Abstract: An implantable medical lead configured for improved MRI safety and heating reduction performance is disclosed herein. In one embodiment, the lead includes a tubular body having a proximal end and a distal end with a lead connector near the proximal end. In this embodiment the lead further includes a conductor extending longitudinally within the tubular body and having a proximal end that is electrically coupled to the connector and a distal end electrically coupled to a contact pin. The lead in this embodiment further includes a filter element electrically coupled to a distal end of the contact pin and a flange electrically coupled between a proximal end of the filter element and a proximal portion of an electrode. In this embodiment the flange and the proximal portion of the electrode form at least a first part of a hermetic chamber enclosing the filter element.

Abstract: A method of manufacturing a lead connector end of an implantable medical lead is disclosed herein. The method may include: provide a mold cavity including a feature and a longitudinal axis; place a ring contact in the mold cavity, engage the ring contact with the feature; fill the mold cavity with a mold material, the feature preventing displacement of the ring contact along the longitudinal axis; allow the mold material to cure; remove a resulting lead connector end from the mold cavity; and reduce an excessive diameter of the resulting lead connector end to a finished diameter.
