Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include an implantable lead. The lead may include a taper or tapered portion and a fixation helix both configured to embed within tissue. In addition, the apparatuses, systems, and methods may include a guide wire configured to obtain and record signals from the heart tissue and facilitate placement of the fixation helix.

Activation fixation lead for cardiac conductive system pacing

A leadless pacing device may include a housing having a proximal end and a distal end, and one or more electrodes supported by the housing. The housing may include a body portion and a header. A distal extension may extend distally from the header of the housing, the distal extension including one or more electrodes. The header may include a guide wire port and a guide wire lumen may extend from the guide wire port through the header of the housing and through the distal extension. A fixation member may extend from the header of the housing. The header may be formed from an over mold process.

Systems and methods for treating cardiac arrhythmias

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an implantable medical device. The implantable medical device may include an implantable pacing member having a housing and a lead input. A lead may be coupled to the lead input. The lead may be designed to extend along a pericardial space, epicardium, or both and engage a heart chamber. A passageway may be defined along a portion of the length of the lead.

Implantable medical devices and methods for making and delivering implantable medical devices

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include an implantable lead having a terminal pin, a conductor member configured to rotate in response to rotation of the terminal pin and a coupler arranged within configured to interface with the conductor member and having a rear bearing surface contacting the inner wall of a housing.

Extendable/retractable active fixation CRM lead tip design for turn count consistency

A catheter for delivering a medical electrical lead to a bundle of His from within a right atrium of a heart. The catheter includes a straight portion and a hook portion projecting from a distal end of the straight portion. The hook portion includes a first curved portion, a second curved portion, and a third curved portion. The straight portion and the first curved portion define a plane. The second curved portion extends from a distal end of the first curved portion. The second curved portion curves away from the plane. The third curved portion extends from a distal end of the second curved portion. The third curved portion curves toward the plane. The catheter forms a lumen extending from a proximal end of the straight portion to an opening at a distal end of the third curved portion.

Bundle of his lead delivery catheter, system and method

A terminal tool includes a main body, an electrical connector body, and an electrical connector. The main body includes a distal clamping section and a shaft. The shaft includes a window and a first lumen extending through the shaft for receiving a terminal end of an implantable lead. The electrical connector body includes a second lumen and is independently rotatable with respect to the main body. The shaft at least partially extends through the second lumen. The electrical connector is coupled to the electrical connector body and extends at least partially through the window of the shaft.

Terminal tool for continuous electrical monitoring during lead implant

A leadless pacing device may include a power supply providing a power supply voltage, a housing having a first end, a second end, and a side extending between the first end and the second end, and a set of electrodes supported by the housing and in communication with the power supply. The housing may be angled to follow a contour of a patient's heart when the housing is positioned within the coronary sinus of the patient's heart. In some cases, an angled portion of the housing may include a smooth-curve. In some cases, an angled portion of the housing may include a first portion of the housing and a second portion of the housing at an angle of less than one-hundred-eighty degrees with respect to the first portion of the housing. One or more of the electrodes may be exposed on a concave side of the angled housing.

A leadless pacing device may include a housing having a proximal end and a distal end, and a set of one or more electrodes supported by the housing. The housing may include a first a distal extension extending distally from the distal end thereof. The distal extension may include a retractable and/or rotatable distal electrode. The distal electrode may be configured to be delivered to and pace at the Bundle of His. The leadless pacing device may be releasably coupled to an expandable anchor mechanism.

Implantable medical device for vascular deployment

Implantable leads of a cardiac stimulus system are disclosed, as well as methods for implanting leads of a cardiac stimulus system. The lead may be comprised of a proximal portion having a coupler for coupling to an implantable pulse generator, an intermediate portion comprising a plurality of electrodes disposed thereon, and a distal portion. The intermediate portion may have a first diameter and the distal portion may have a second diameter. The distal portion may also have an attachment feature for attaching to a lead pulling tool for delivery to an ITV and an intercostal vein. Methods may include pulling a lead from a first position to a second position within the vasculature, exiting the vasculature at the second location, and attaching a portion of the lead that exits the vasculature to an electrode or implantable device for use with the lead.

Active medical device with attachment features

Implantation of a cardiac stimulus system using an illuminating catheter system, and devices for such implantation. Multiple catheter systems for allowing for selective visualization of the internal thoracic vasculature are discussed and disclosed. A multiple lumen catheter may be used to selectively direct a contrast agent to a desired portion of the thoracic vasculature which may include the internal thoracic vein(s) and/or one or more intercostal veins.

Implantation of an active medical device using the internal thoracic vasculature

A leadless pacing device may include a power supply for providing a power supply voltage, a housing having a first end and a second end with a side extending between the first end and the second end, and a set of electrodes supported by the housing and in communication with the power supply. When leadless pacing device is disposed within a coronary sinus of a patient's heart, the housing may facilitate blood flow across the housing. The housing may include fixing members extending radially outward from the side of the housing to engage a wall of the coronary sinus and expand the coronary sinus to allow blood to flow past the housing. In some cases, the housing may have a recess along a length thereof that allows blood to flow past the housing. The recess may include a groove, a flat feature, or other feature.
