Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

A catheter devices/systems and methods therefrom are described herein for treating acute kidney in-jury, especially the contrast-induced acute kidney injury wherein the devices prevent the contrast dyes from entering into kidney and/or facilitate blood flow of kidney by said catheter system.

An apparatus is disclosed including: an intracardiac pump device having a path for a guidewire extending through the pump device from a first opening to a second opening; and a lumen which extends from a first end located outside of the pump device, into the pump device through the first opening in the pump device, along the path for the guidewire, out of the pump device through the second opening, and to a second end located outside of the pump device. The lumen is configured to receive the guidewire such that when the guidewire passes through the lumen from the first end to the second end, the guidewire is positioned along the path.

A method and devices for mitigating the risk of limb ischemia includes inserting a femoral arterial cannula into a femoral artery of a limb, the femoral arterial cannula having a low-profile balloon to seal the femoral artery. Once in situ in the femoral artery, the femoral arterial cannula balloon is inflated to seal said femoral artery to deliver blood flow in a retrograde direction to said limb while simultaneously delivering systemic arterial blood flow. A femoral venous cannula is also inserted into a femoral vein of said limb, the femoral venous cannula having a broad-profile balloon to seal the femoral vein. Once in situ in said femoral vein, the femoral venous cannula balloon is inflated to seal the femoral vein to drain venous blood flow from the limb while simultaneously draining systemic venous blood flow.

Techniques and systems for using spectroscopy- and/or image-based sensing with an intravascular blood pump may be provided. The techniques generally include capturing a spectral response to light of a measured tissue and/or blood. Based on the specific needs, the method may include, e.g., determining a type of the measured tissue based on the spectral response, determining if the type of the measured tissue matches a target tissue type, determining a health of the measured tissue based on the spectral response, determining a treatment plan based on the health of the measured tissue, determining a type and/or quantity of components and/or characteristics in the blood, and/or determining a degree of heart recovery based on the type and/or quantity of the components and/or characteristics in the blood.

A pumping system (200) for controlling the flow of interatrial blood comprises, housed inside a container (201), a control element (30, 30′, 30″) of the interatrial blood flow. The control element comprises: at least one worm screw (31), the rotation of which creates a two-way flow of interatrial blood; or a pair of counter-rotating propellers (31′); or a pair of membranes (31″) whose deformation creates a two-way flow of interatrial blood; or a flexible structure (31″) whose change in volume within the container (201) creates a two-way flow of interatrial blood.

A connector for connecting an implant device to tissue of a person's body. The connector including a frame having first and second arms. The first and second arms define an opening, where at least a portion of the implant device is inserted through the opening. After insertion, an additional securing member is connected to the frame. The securing member is adapted to receive at least one suture to secure the frame to the tissue. The connector includes an adjuster that is movably connected to the first and second arms, where the adjuster is operable to cause the first and second arms to move toward each other and engage the implant device.
