One embodiment discloses a computerized method of facilitating cardiac intervention, comprising inputting patient data, creating a computerized interactive model of a heart based on the patient data, wherein the model comprises features, simulating at least one proposed cardiac intervention treatment by adding or deleting features to the model, and determining the effects of the proposed cardiac simulation upon the entire model. Simulations may be repeated to allow the user to determine an optimal cardiac intervention. Additionally, a template may be created from the model to use as a guide during the cardiac intervention.

System and method for facilitating cardiac intervention

One embodiment discloses a computerized method of facilitating cardiac intervention. The method may include inputting patient data and creating a computerized interactive model of a heart based on the patient data. The model may include features. The model may simulate at least one proposed cardiac intervention by adding or deleting features to the model, and determining the effects of the proposed cardiac simulation upon the entire model. Simulations may be repeated to allow the user to determine an optimal cardiac intervention. A template and/or patient specific instrument may be created from the model to use as a guide during the cardiac intervention.

Method for image processing and contour assessment of the heart

One embodiment discloses a computerized method of facilitating cardiac intervention, comprising inputting patient data, creating a computerized interactive model of a diseased heart based on the patient data, wherein the model comprises structural elements, simulating at least one proposed cardiac intervention treatment by adding or deleting structural elements to the model, and determining the effects of the proposed cardiac simulation upon the entire model. Simulations may be repeated to allow the user to determine an optimal cardiac intervention. Additionally, a template may be created from the model to use as a guide during the cardiac intervention.

In one embodiment, there is disclosed a method for repairing a heart of a human, comprising introducing a collapsed shaping device through the skin into the vascular system of the human, delivering the shaping device into a left ventricle through the arteries, once inside the left ventricle, expanding the shaping device to an expanded shape, imbricating a wall of the ventricle over the shaping device, collapsing the shaping device, and removing the shaping device from the left ventricle such that the ventricle is restored to an appropriate size.

Method and device for percutaneous surgical ventricular repair

Apparatuses and methods are provided to reconstruct an enlarged left ventricle of a human heart, using a shaper, having a size and shape substantially equal to the size and shape of an appropriate left ventricle, wherein the shaper is adapted to be temporarily placed into the enlarged left ventricle during a surgical procedure. Another aspect of one embodiment comprises a ventricular patch adapted for placement into the left ventricle of a heart made from a sheet of biocompatible material, and having a plurality of markings coupled to the sheet, wherein the markings are configured in distinct patterns for post operatively evaluating movement of the patch. In another aspect of one embodiment, a device is presented, comprising of a handle and a sizing template adapted to be coupled to the handle. Such components are also presented as a kit for use during ventricular restoration surgery.

A catheter and method of use may include an aortic balloon catheter having an integral expandable/collapsible lumen. The catheter comprises a main catheter body having a either a single or a plurality of lumens extending therethrough, and further includes an expandable/collapsible lumen disposed thereabout and carried by the main catheter body. The expandable/collapsible lumen has a relatively large diameter when inflated with respect to the main catheter body, and is self-inflating by fluid pressure when the fluid flows therethrough. The large inflatable/collapsible lumen is attached at its distal end to the main catheter body and thus is carried therewith into a body vessel, and thus is also supported by the catheter body to avoid kinking. The present invention also achieves technical advantages as a catheter for insertion into any body vessel having a limited diameter and which is susceptible to trauma, such as a urethra.

Catheter having integral expandable/collapsible lumen

A catheter (,) having both a flexible (,) and a rigid reinforcement section (,). The catheter body (,) is comprised of an elastomeric material, such as silicone, having a resilient coil or spring member (,) within a fluid delivery lumen (,) along the proximal portion (,) thereof. The catheter is provided with a more rigid malleable reinforcement member (,) at the distal portion (,) thereof, also extending within the fluid delivery lumen (,) and positioned proximal the coil member (,) within the fluid delivery lumen (,). The rigid reinforced distal portion (,) of the catheter body helps the surgeon to hold the tip of the catheter more firmly, and makes insertion of the catheter tip into the body vessel easier. The more flexible support portion (,) at the proximal portion (,) of the elastomeric catheter body reinforces the catheter to prevent kinking, yet allows flexibility to facilitate the surgeon to move the proximal portion (,) of the catheter out of the surgical site. The catheter body may be provided with a balloon (,) and a hinge portion (,), such as defined by an annular detent (,), to allow the catheter tip to self-align within the body vessel when the balloon is inflated. Both the flexible (,) and rigid (,) reinforcement sections are tubular to facilitate fluid delivery therethrough within through the lumen (,) through which the reinforcement members (,and,) reside.

Catheter with flexible and rigid reinforcements

A catheter system and method of performing posterior epicardial revascularization and intracardiac surgery on a beating heart. Several catheter systems are provided to achieve a left ventricular isolation and a right ventricular isolation as required to facilitate surgery according to the methods of the present invention. Myocardial infusion is provided in either antegrade or retrograde flow to insure the myocardium meets its oxygen demand.

A catheter and method of use as an aortic balloon catheter having an integral expandable/collapsible lumen. The catheter comprises a main catheter body having a plurality of lumens extending therethrough, and further includes an expandable/collapsible lumen disposed thereabout and carried by the main catheter body. The expandable/collapsible lumen has a relatively large diameter when inflated with respect to the main catheter body, and is self-inflating by fluid pressure when the fluid flows therethrough. The large inflatable/collapsible lumen is attached at its distal end to the main catheter body and thus is carried therewith into a body vessel, and thus is also supported by the catheter body to avoid kinking. The catheter of the present invention is ideally suited for insertion into smaller access arteries for placement into larger arteries, such as an aortic balloon catheter which can be inserted into a smaller femoral artery and advanced into the ascending aorta to provide arterial return of oxygenated blood into the ascending aorta. The catheter further has an adjustable length. The present invention also achieves technical advantages as a catheter for insertion into any body vessel having a limited diameter and which is susceptible to trauma, such as a urethra.
