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

An electrode assembly for the positioning of an electrode of an implantable medical lead includes a housing and an electrode subassembly. The housing includes a proximal end for connecting to the lead and a distal end. The housing defines a housing lumen extending between the proximal end and the distal end. The housing lumen includes internal screw threads extending along at least a portion of the housing lumen. The electrode subassembly is disposed at least partially within the housing lumen. The electrode subassembly includes a needle electrode and a coupler. The needle electrode is disposed coaxially with the longitudinal axis of the housing lumen. The coupler is disposed at a proximal end of the needle electrode. The coupler includes external screw threads engaged with the internal screw threads of the housing lumen such that rotation of the coupler moves the needle electrode along the longitudinal axis of the housing lumen.

Implantable lead with extensible electrode and repositioning features

A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, and rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen having a longitudinal axis extending between the proximal end and the distal end. The tine assembly is disposed within the housing lumen. The tine assembly includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The rotatable shaft extends through the housing lumen. The shaft is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.

Stimulation/sensing electrode fixation device and electrical lead

A device for the active fixation of an implantable medical lead includes a housing, a tine assembly, an electrode, and a rotatable shaft. The housing includes a proximal end for connecting to the lead and a distal end opposite the proximal end. The housing defines a housing lumen extending between the proximal end and a recess adjacent to the distal end. The tine assembly is disposed within the housing lumen and includes at least one tine configured to self-bias from a linear configuration within the housing to a curved configuration outside of the housing. The electrode assembly is disposed at the distal end of the housing and includes a plurality of electrodes. The rotatable shaft extends through the housing lumen and is configured to engage the tine assembly such that rotation of the shaft transitions the at least one tine between the linear configuration and the curved configuration.

Multipolar lead for His bundle pacing

An implantable medical electrical lead connectable to an electrical header of an implantable medical device includes a lead body extending from a proximal end to a distal end, a lead terminal disposed at the proximal end of the lead body and configured to couple the lead to the electrical header, and a lead boot disposed at the lead terminal. The lead boot includes a strain relief portion and a seal portion. The strain relief portion is formed of a first elastic polymer and the seal portion is formed of a second elastic polymer. The first elastic polymer is different from the second elastic polymer.

Medical electrical lead terminal boot and method of making

A system may include a leadless cardiac pacing device including a body, a proximal hub, and a helical fixation member opposite the proximal hub; and a first elongate shaft having a lumen extending from a distal end of the elongate shaft proximally into the elongate shaft and a transverse member extending transversely across the lumen. The proximal hub may include a transverse channel extending into the proximal hub, the transverse channel being configured to engage the transverse member.

Tools and systems for implanting and/or retrieving a leadless cardiac pacing device with helix fixation

His lead with extensible electrode and repositioning features

An implantation and/or retrieval device for a leadless cardiac pacing device may include a first elongate shaft including a lumen; a second elongate shaft slidably disposed within the lumen of the first elongate shaft; an end cap assembly fixedly attached to a distal end of the first elongate shaft; and a plurality of wires attached to the second elongate shaft and extending distally from the end cap assembly, the plurality of wires being movable relative to the end cap assembly. The plurality of wires is configured to engage a proximal hub of the leadless cardiac pacing device. The plurality of wires forms a plurality of wire loops extending distally from the end cap assembly.

An implantable medical device includes a device housing, a fixation device, a first prong projecting from a proximal end of the device housing and a second prong projecting from the proximal end of the device housing. The second prong is spaced apart from the first prong. The first prong includes a first flange projecting away from a longitudinal axis of the device housing. The second prong includes a second flange projecting away from the longitudinal axis. The first prong and the second prong are configured to extend to a first flange diameter in a relaxed configuration and to extend to a second flange diameter in an expanded configuration.

Implantable medical device and delivery catheter apparatus system and method

Various aspect of the present disclosure are directed toward apparatuses, systems, and methods that may include an introducer for facilitating placement of an implantable monitor. The introducer may include an indicator configured to indicate at least one of width, depth, and position for an arrangement of the implantable monitor relative to a patient.

Implantable monitor introducer
