Cardiac ablation catheters include an outer balloon positioned at a distal end of the catheter and configured to have an inner balloon disposed therein. The outer balloon is inflated with a first fluid that has a temperature less than 100 degrees Celsius, while the inner balloon is inflated with heated vapor. An area of contact between the two balloons, comprising a surface area less than the total surface area of either balloon, creates a hot zone for ablating cardiac tissue through the transfer of thermal energy from the contact area to the cardiac tissue.

An improved system for supporting (e.g., localization and/or positioning of) intravascular devices discussed herein provides for example a multi-element arrangement. A set of struts optionally projects from the intravascular device and contacts the vessel walls. The localization and positioning of the pump may be provided by the struts and/or by use of a tether opposing a propulsive force to ensure localization.

Support structures for intravascular blood pumps

A renal denervation feedback method is described that performs a baseline measurement of renal nerve plexus electrical activity at a renal vessel; denervates at least some tissue proximate the renal vessel after performing the baseline measurement; performs a post-denervation measurement of renal nerve plexus electrical activity at the renal vessel, after the denervating; and assesses denervation of the renal vessel based on a comparison of the baseline measurement and the post-denervation measurement of renal nerve plexus electrical activity at the renal vessel.

Devices, systems, and methods for communicating with an implantable medical device are disclosed. A communication device may include an input/output interface configured to communicate with a wireless communication device, a communication interface configured to communicate with a remote system, a detector configured to detect when the wireless communication device is within a range of the non-implantable communication device, wherein communication between the wireless interface and the wireless communication device is initiated upon detection by the detector that the wireless communication device is within the range of the non-implantable communication device, and a processor configured to perform an analysis of data received from the wireless communication device via the input/output interface and associated with the implantable medical device. The communication device may include a user interface configured to receive data input by a user. A communication system may include a wireless communication device and the aforementioned communication device.

A method and system are provided for removing, from an implant chamber of a heart, a leadless implantable medical device (LIMD) having a distal end and a proximal end. The distal end is configured to be actively secured to tissue in the implant chamber of the heart. The proximal end is configured to be coupled to a distal end of an indwelling retrieval mechanism (IRM). The IRM extends from the heart along a vessel, the IRM having a proximal end configured to be anchored at a temporary anchor site. The method comprises detaching the IRM from the anchor site, loading a retrieval tool over the proximal end of the IRM and along the body of the IRM. The retrieval tool has a lumen therein that receives the IRM as the retrieval tool re-enters the vessel, thereby allowing the retrieval tool to engage the LIMD.

A communication device for an implantable medical device may include: an input/output interface configured to communicate with a wireless communication device; a communication interface configured to communicate with a remote system; and a processor configured to perform an analysis of data received from the wireless communication device via the input/output interface and associated with the implantable medical device. The communication device may include a user interface configured to receive data input by a user. A communication system may include a wireless communication device and the aforementioned communication device. A communication method for an implantable medical device may include: providing a communication device that is configured to communicate with a wireless communication device, to communicate with a remote system and to perform an analysis of data; communicating data associated with an implantable medical device from a wireless device to the communication device; and analyzing the received data at the communication device.

A method for detecting potential failures by a lead of an implantable medical device is provided. The method includes sensing a first signal over a first channel between a first combination of electrodes on the lead and sensing a second signal from a second channel between a second combination of electrodes on the lead. The method determines whether at least one of the first and second signals is representative of a potential failure in the lead and identifies a failure and the electrode associated with the failure based on which of the first and second sensed signals is representative of the potential failure. Optionally, when the first and second sensed signals are both representative of the potential failure, the method further includes determining whether the first and second sensed signals are correlated with one another. When the first and second sensed signals are correlated, the method declares an electrode common to both of the first and second combinations to be associated with the failure.
