Abstract: Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.

Abstract: A percutaneous pumping system for providing hemodynamic support to a patient includes a pumping sleeve that defines a lumen extending along the length of the pumping sleeve. The pumping sleeve is configured and arranged for insertion into patient vasculature. At least one rotatable magnet is disposed in the pumping sleeve. The at least one first magnet is configured and arranged to be driven to rotate by a magnetic field generated external to the pumping sleeve. At least one impeller is coupled to the at least one magnet. Rotation of the at least one magnet causes a corresponding rotation of the at least one impeller. An anchoring arrangement is coupled to the pumping sleeve. The anchoring arrangement is configured and arranged to anchor the pumping sleeve at a target pumping location when the pumping sleeve is inserted into patient vasculature.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device includes a pressure sensing guidewire. The pressure sensing guidewire may include an elongate shaft including a core wire having a distal portion and a coil disposed over the distal portion. A pressure sensor may be disposed along the distal portion of the core wire and within the coil. One or more leads may be coupled to the pressure sensor. An opening may be formed in the coil that provides access to the pressure sensor.
