Abstract: An implantable medical lead comprising a lead body defining a lumen. The lead body includes one or more tines substantially at a distal end of the lead body. An inner member extending within the lead body lumen is configured to rotate relative to the lead body and configured to cause a rotation of a dilator. The dilator is configured such that the rotation causes or enables a lateral translation of the dilator from a first position proximal to a lead body opening to a second position distal to the lead body opening. The implantable medical lead may include a probe wire configured to slidably translate through an inner lumen of the dilator.

Abstract: Devices, systems, and techniques for transitioning between different drug delivery sources or different drug concentrations may account for diffusion and mixing of drug within the fluid. In one example, a method may include determining a flow rate for a fluid to be delivered to a patient via a drug pump and a catheter in fluid communication with a reservoir of the drug pump. The fluid includes a drug. The method also includes determining a concentration profile of the drug delivered via the catheter, wherein the concentration profile identifies a volume of delivered fluid needed to achieve a target transition dose of the drug. The method further includes determining, by a processor and based on the flow rate and the concentration profile, an initial delivery period required to achieve the target transition dose by delivering the fluid at the flow rate.

Abstract: 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.

Abstract: A method for reducing small volume subcutaneous leaks of therapeutic fluids during procedures to refill an implantable medical device includes reducing pressure in a reservoir of the device. A refill needle can be percutaneously inserted into a fill port in communication with the reservoir and therapeutic fluid can be delivered through the needle into the reservoir. Reduced reservoir pressure upon withdrawal of the refill needle from the port can result in reduced subcutaneous leakage of the therapeutic fluid.
