Assignee:

Chase Medical, Inc. - Richardson TX

International Classification:

A61B 1900

US Classification:

128898, 600 16, 600587, 623 31, 33512

Abstract:

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.

Gregory Murphy - Richardson TX, US
Albert Davis - Richardson TX, US
Mitta Suresh - Richardson TX, US

Assignee:

Chase Medical, L.P. - Richardson TX

International Classification:

G06K 9/00

US Classification:

382128, 128922, 378 4

Abstract:

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.

US Classification:

600 37, 623 31

Abstract:

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.
