A method and implantation tools for repairing a heart include a delivery catheter and implant. The method includes gaining access to the patient's heart and identifying implantation points for the implant. The method may include marking those locations and delivering implant, which may be a tension member. Anchors for the implant may also be delivered. The length of the tension member may be measured and the walls of the heart drawn together. Pads may be secured to the tension member and the tension member trimmed to length. The pads may be secured to the heart surface.

Transventricular implant tools and devices

An external heart wall stress reduction apparatus is provided to create a heart wall shape change. The device is generally disposed to the exterior of a heart chamber to reshape the chamber into a lower stress configuration.

External cardiac stress reduction method

A method and implantation tools for placing a transventricular splint including a tension member. The method includes gaining access to the patient's hearts and identifying entry or exit points for the tension member, marking those locations and delivering the tension member. Anchors for the tension member are also delivered. The length of the tensions member is measured and the walls of the heart drawn together. The pads are secured to the tension member and the tension member is trimmed to length. The pads are secured to the heart surface.

An angiographic injector system includes a manifold and valve which selectively connects either a syringe pump or a low pressure system to a catheter which is inserted into a patient. The valve is normally biased to a state which connects the low pressure system to the catheter for pressure monitoring, saline flushing, or aspirating functions. When an injection is to be made, the valve automatically switches so that the low pressure system is disconnected and not exposed to high pressure, while the syringe pump is connected through the manifold to the catheter.

Angiographic injector and injection method

A dual port syringe has an upper port for connection to a fluid reservoir and a lower port for delivery of the medical fluid under pressure to a patient. A first valve is connected between the fluid reservoir and the upper port, and second valve is connected between the lower port and the patient. During a fill operation, a piston is moved within the syringe to drawn fluid from the reservoir into the syringe through the upper port. During injection operation, the piston moves in an opposite direction to force fluid out of the syringe through the lower port.

System for detecting air

A splint assembly for placement transverse a heart chamber to reduce the heart chamber radius and improve cardiac function has a tension member formed of a braided cable with a covering. A fixed anchor assembly is attached to one end of the tension member and a leader for penetrating a heart wall and guiding the tension member through the heart is attached to the other end. An adjustable anchor assembly can be secured onto the tension member opposite to the side on which the fixed pad assembly is attached. The adjustable anchor assembly can be positioned along the tension member so as to adjust the length of the tension member extending between the fixed and adjustable anchor assemblies. The pad assemblies engage with the outside of the heart wall to hold the tension member in place transverse the heart chamber. A probe and marker delivery device is used to identify locations on the heart wall to place the splint assembly such that it will not interfere with internal heart structures. The device delivers a marker to these locations on the heart wall for both visual and tactile identification during implantation of the splint assembly in the heart.

External stress reduction device and method

An angiographic injector system includes a manifold and valve which selectively connects either a syringe pump or a low pressure system to a catheter which is inserted into a patient. The valve is normally biased to a state which connects the low pressure system to the catheter for pressure-monitoring, saline flushing, or aspirating functions. When an injection is to be made, the valve automatically switches so that the low pressure system is disconnected and not exposed to high pressure, while the syringe pump is connected through the manifold to the catheter.
