摘要： The present disclosure belongs to the technical field of artificial cardiac pacemakers, and particularly relates to a leadless left-bundle-branch pacemaker. The leadless left-bundle-branch pacemaker comprises a case and an implant core, wherein the implant core is coaxially arranged inside the case, and a head of the implant core can be rotated out from the inside of the case; the implant core has an implant end that can be rotated out from the inside of the case, and the length of the implant end rotated out from the inside of the case is greater than 10mm; and an end of the case corresponding to the implant end is provided with a fixing end for fixing the pacemaker. After the fixing end is fixed to the myocardial wall, the implant core is "screwed into" the interventricular septum and can be rotated out from the case with different lengths according to the thickness of the interventricular septum of each person, such that the head of the implant core is rotated into the subendocardial left-bundle-branch area of the left ventricle. In this way, the leadless left-bundle-branch pacemaker can synchronously pace the left ventricle, thus solving the problem of current leadless pacemakers being unable to achieve physiological pacing.

摘要： A medical lead system comprising: a first lead portion comprising a first elongate body extending along a longitudinal axis from a distal end to a proximal end and a coupling member; and a second lead portion comprising a second elongate body extending along the longitudinal axis from a distal end to a proximal end, wherein the distal end of the second lead portion comprises a connector defining a channel configured to receive the proximal end of the first lead portion, wherein the connector defines a coupling recess (688), and wherein the coupling member is configured to, when the first lead portion is inserted into the channel, mechanically engage the coupling recess to secure the first lead portion to the second lead portion at least in an axial direction relative to the longitudinal axis, and wherein one of the first lead portion or the second lead portion carries one or more electrodes.

摘要： High-density mapping catheters with an array of mapping electrodes are disclosed. These catheters can be used for diagnosing and treating cardiac arrhythmias, for example. The catheters are adapted to contact tissue and comprise a flexible framework including the electrode array. The array of electrodes may be formed from a plurality of columns of longitudinallyaligned and rows of laterally-aligned electrodes.

摘要： Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a single pass implantable lead configured to be coupled to the implantable medical device and arranged to sense and pace the chambers of a patient's heart. The lead may include a proximal region having a plurality of electrodes, a distal region having at least one electrode, and an intermediate region therebetween. The system can sense and pace the right atrium, the left atrium, the right ventricle, and the left ventricle.
