A medical apparatus is provided that includes an implantable element, in particular a heart pump, and a control unit for the implantable element, which control unit is connected to the implantable element by means of a first connection. The problem of arranging an antenna of a radio module on the control unit expediently and favourably is solved in that the control unit is configured for arrangement outside the patient's body and has a predetermined orientation relative to the patient's body and has a radio module, wherein an antenna of the radio module is arranged in such a way that the region in which the patient's body is intended to be positioned, as considered from the control unit, is shielded from the antenna at least in part by electromagnetically shielding, in particular electrically conductive parts of the control unit or housing thereof.

Devices, systems and methods for establishing a blood flow conduit between a chamber in a heart of a patient and a remote location. A blood inflow cannula having an outer surface and proximal and distal end portions. The distal end portion is configured for insertion into the chamber of the heart. First and second anchor elements have respective maximum width dimensions extending outwardly from the outer surface of the cannula. The first anchor element is positioned more distally than the second anchor element defining a tissue receiving space therebetween. The maximum width dimension of the first anchor element may be larger than the maximum width dimension of the second anchor element in use. The first anchor element is configured to be positioned inside the heart chamber and the second anchor element is configured to be positioned outside the heart chamber with heart tissue held in the tissue receiving space therebetween.

This document discusses, among other things, systems and methods to reduce ischemic or metabolic injury to a patient's heart. A system to reduce ischemic or metabolic injury to a patient's heart may include a pulse generator for generating electrical pulses or shock, a pacing lead with at least one pacing electrode configured to deliver electrical pulses received from the pulse generator to the patient's heart, a controller configured to control timing of electrical pulses to reduce wall stress of the heart, and a reservoir, fluidically coupled to a lumen and a pump, wherein the pump is configured, under control of the controller, to move contents from the reservoir through the lumen to an area of the heart with the reduced wall stress, wherein the contents include autologous respiration-competent mitochondria or other respiratory-promoting agents.

A method and kit for placing an implant in a patient. The method includes placing an implant consisting of at least one from the group consisting of an electronic device and an electromechanical device into a tissue cavity of the patient and evacuating fluid from the cavity and urging tissue surrounding the cavity to abut the implant.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that may include an inflow or outflow cannula apparatus.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that may include an inflow or outflow cannula apparatus.

A system and method of drawing blood from the heart of a patient. The system includes a blood pump, an outflow cannula, and a flexible cannula assembly. The flexible cannula assembly includes a cannula body, a tip, and first and second anchors. The cannula body includes a proximal end coupled to the inlet of the blood pump, a distal end including a first locking element coupled to the tip. The first anchor has a first plurality of arms and is coupled to the tip and adapted to engage the internal surface of the heart wall. The second anchor includes a second plurality of arms and a second locking element and is slidably positioned on the outer wall of the cannula body and adapted to engage the first locking element of the distal end of the cannula body to couple the second anchor to the external surface of the heart wall.

This document describes, among other things, a computer-implemented method that includes receiving, by a computing system, data that represents a plurality of measurements associated with a mechanical circulatory support device connected to a patient over a period of time. The method can include determining, based on the plurality of measurements, respective trends for one or more operating characteristics of the device over the period of time, and generating a respective representation for each of the trends that is formatted for presentation to a user for assessing whether the trends indicate a likelihood of an operational defect associated with the device. The method can include providing the respective representations to the user.

A connector is provided for fluid communication between two anatomical compartments through at least one anatomical wall, wherein the connector comprises a neck adapted and configured to be positioned across the anatomical wall(s); primary means for securing the neck across the anatomical wall(s); and secondary means for securing the neck across the anatomical wall(s). A method for coupling two anatomical walls using said connector is also provided.

Thermal management solutions for wireless power transfer systems are provided, which may include any number of features. In one embodiment, an implantable wireless power receiver includes at least one thermal layer disposed on an interior surface of the receiver configured to conduct heat from a central portion of the receiver towards edges of the receiver. The thermal layer can comprise, for example, a copper layer or a ceramic layer embedded in an acrylic polymer matrix. In some embodiments, a plurality of thermal channels can be formed within the receiver to transport heat from central regions of the receiver towards edges of the receiver via free convection. In yet another embodiment, a fluid pipe can be connected to the receiver and be configured to carry heat from the receiver to a location remote from the receiver. Methods of use are also provided.
