Implant tools and techniques for implantation of a medical lead, catheter or other component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An implant tool for implanting a medical lead may include a handle and a shaft adjacent the handle. The shaft has a proximal end, a distal end, and an open channel that extends from near the proximal end to the distal end, the open channel having a width that is greater than or equal to an outer diameter of the implantable medical lead.

Systems and methods are provided for determining an estimated risk of arrhythmia during or after dialysis based on changes in serum potassium concentration of a patient and an amount of fluid removed from the patient during dialysis. The systems and methods allow for a determination of a risk that arrhythmia will occur due to the changes in potassium and fluid volume of a patient during dialysis, and for optimizing a dialysis prescription in order to minimize the risk of arrhythmia.

Dialysis prescription optimization for decreased arrhythmias

A system and method for controlling a monitoring mode or treatment mode of an implantable medical device based on the detection of an external signal. The system and related method allow for more frequent monitoring of medical parameters at times where more frequent monitoring is necessary, such as during or after a dialysis session, with less frequent monitoring at other times, allowing for a more efficient medical device. The invention also allows for the frequency or mode of treatment by the implantable medical device, or the transmission of data from the implantable medical device to be controlled based on the external signal.

Implant tools and techniques for implantation of a medical lead, catheter or other implantable component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An example implant tool for implanting a medical lead includes a rod having a handle and a shaft, and a sheath configured to be placed on the shaft of the rod. The sheath includes a body having proximal end and a distal, a channel formed by the body, the channel extending from the proximal end to the distal end of the body, and an opening that extends along the body of the sheath from the proximal end to the distal end, wherein the channel is accessible via the opening.

Implant tools and techniques for implantation of a medical lead, catheter or other implantable component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An example implant tool for implanting a medical lead includes a rod and a sheath configured to be placed on the rod. The rod includes a handle, a shaft having a proximal end adjacent to the handle and a distal end, and an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead. The sheath is configured to be placed in multiple positions along the rod including a first position in which the sheath does not interact with the attachment feature and second position in which the sheath does interact with the attachment feature.

Implant tools and techniques for implantation of a medical lead, catheter or other component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An implant tool for implanting a medical lead may include a shaft having a proximal end, a distal end, an open channel that extends from near the proximal end to the distal end, and an attachment feature configured to couple to the medical lead. Such an implant tool provides a user with the versatility to use the same implant tool to either pull the lead through a tunnel formed via the implant tool or push the lead through the tunnel via the open channel in the implant tool.
