A movable gate on the suture crimp can be actuated to secure the sutures at an appropriate tension to maintain the leaflets in a coapted position.

Disclosed is a computer-implemented method for non-invasive estimation of Pulmonary Hypertension, PH, from heart sound signals. Consistent with the disclosure, the method includes the steps of: receiving a sound signal acquired from a beating heart of a subject over a predetermined time period; generating one or more 2D feature maps comprising a 2D feature map with the received sound signal where a first axis of the map is arranged over time and a second axis of the map is arranged over individual heartbeats; applying a pre-trained neural network to relate the generated one or more 2D feature maps with a training dataset of previously acquired and generated training 2D feature maps of a PH subject group and a non-PH subject group, thus to obtain an indicator of the presence of Pulmonary Hypertension. Also disclosed is a training method of said neural network and a system.

To provide a method for treating a heart condition by perfusing a drug to an unarrested beating heart of a patient.SOLUTION: A closed circuit may be formed by using a first drug delivery catheter 122 positioned in a patient's right coronary artery, a second drug delivery catheter 124 positioned in the patient's left main coronary artery, a drug collection catheter positioned in a coronary sinus, the coronary artery, the coronary venous system, and an external membrane oxygenator 120 interspersed between the venous and arterial branches. A drug for treating a heart condition may be perfused through the closed circuit.SELECTED DRAWING: Figure 1A

This invention relates to the design and function of a compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.
