A device configured to deliver and deploy an implantable medical device (IMD) includes a handle assembly and a shaft extending distally therefrom. A device containment housing configured to accommodate the IMD is coupled to the distal region of the shaft. At least one of the shaft and device containment housing includes a compressible region that is configured to compress by an amount that is related to an applied force. The device may include a first position indicator and a second position indicator. An applied force causes the compressible region to compress by an amount that is related to the applied force, causing a change in distance between the first position indicator and the second position indicator and thus providing an indication of the applied force.

An implantable medical system includes an implantable catheter advanceable into a coronary sinus of a patient's heart. A guide element and an implantable lead receivable in the side lumen is advanceable through an angled opening of the catheter to be deflected laterally away from the catheter at the deflection angle to position the at least one testing electrode or at least one pacing electrode, respectively, in a myocardium of the patient's heart when the distal portion of the catheter is positioned in the coronary sinus.

A system and method of implanting pacing lead in a patient's heart. The system may include a catheter configured to by inserted through the coronary sinus ostium such that the distal end region of the catheter is positioned past the anterolateral vein and proximate at least one septal perforating vein. The catheter is configured to inject contrast proximate the septal perforating vein to identify an implant region for a pacing lead. Further, a controller is configured to deliver pacing therapy to the implant region.

Apparatus and methods for placement of electrodes into selected tissue, such as the septal wall separating the left and right ventricles, with, in some cases, access to the septal wall from the right ventricle. Torque sleeves may be used to provide for rotation as needed.

The present technology is generally directed to medical implants, such as stimulation assemblies for stimulating heart tissue. In some embodiments, a stimulation assembly includes a body, circuitry positioned at least partially within the body, an electrode coupled to the body, and a hook mechanism coupled to the body. The stimulation assembly can be implanted at cardiac tissue of a patient such that the electrode electrically contacts the tissue. The circuitry can be configured to receive acoustic energy and convert the acoustic energy to electrical energy, and the electrode can deliver the electrical energy to the tissue to stimulate the tissue. The hook mechanism can be configured to engage the tissue to pull the tissue and the electrode toward and into engagement with one another.

Embodiments include a medical implant including a fixing device with at least one fixing element to fix the implant at a site of implantation. The implant includes a belt drive that rotates an actuation device, wherein the actuation device is coupled to the fixing device and converts the rotary movement into a longitudinal movement of the fixing device. Embodiments include an insertion device to insert the medical implant.

A His bundle-detecting snare catheter according to the present invention detects a myocardial electrical signal and locates the position of a His bundle through the insertion of a snare and an EP catheter into a dual lumen catheter having two lumens, and captures a cerclage wire, which has passed through the His bundle, and safely guides same into a body. The His bundle-detecting snare catheter according to the present invention comprises: a dual lumen catheter having formed therein a first lumen and a second lumen; an electrical signal detection catheter which is inserted into the first lumen or the second lumen and detects a myocardial electrical signal; and a snare which is inserted into the first lumen or the second lumen and has one or more annular wires at a distal portion thereof, wherein the electrical signal detection catheter and the snare are inserted into different lumens.

An implantable extravascular electrode lead, having a proximal end and a distal end, comprises an electrode lead body that extends from the proximal end of the electrode lead to the distal end of the electrode lead, a connecting device arranged at the proximal end of the electrode lead body, and a fixing device arranged in the distal region of the electrode lead body or at the distal end of the electrode lead body. Once the electrode lead has been inserted into an extravascular region of a patient, the fixing device is actively actuatable from outside the body for fixing the electrode lead to patient body tissue.

The present disclosure relates to a device for valve regurgitation surgery and pacemaker lead fixation, and more particularly, to a device for valve regurgitation surgery and pacemaker lead fixation that allows mitral regurgitation surgery, tricuspid regurgitation surgery, and fixation of a pacemaker lead to an interventricular septum to be performed using a single device. The device for valve regurgitation surgery and pacemaker lead fixation according to the present disclosure includes a cerclage wire, a coronary sinus tube which has a lumen formed to insert the cerclage wire thereinto and which is inserted into a coronary sinus, a tricuspid valve tube which has a lumen formed to insert the cerclage wire thereinto and which crosses a tricuspid valve and protects tissues of the tricuspid valve and the interventricular septum, a lead insertion tube which is coupled to the tricuspid valve tube and has an end facing the interventricular septum, and a pacemaker lead which is inserted into the lead insertion tube and has an end inserted into the bundle of His.
