Kit and method for use during ventricular restoration
View Patent ↗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.

4. The kit of claim 1 , wherein the expandable shaper is configured to be expanded with a fluid.
5. The kit of claim 1 , further comprising a pressure transducer, wherein the pressure transducer is configured to monitor a pressure inside the expandable shaper.
6. The kit of claim 1 , further comprising a patch holder, wherein the patch holder is configured to place the heart patch on the heart, and wherein the patch holder is configured to be removed after suturing of the heart patch has begun.
7. A pre-fabricated, sterile kit for use during left ventricle reconstructive surgery to provide tools and apparatus to interoperatively construct a heart patch, reconstruct a left ventricle, and close an incision using the heart patch, the kit comprising:
bio-compatible material having markings, wherein the markings are configured in distinct patterns for post operatively evaluating the movement of the heart patch;
a series of sizing templates differing in size in which a surgeon can selectively position one such sizing template at or in an opening in the left ventricle, wherein the one such sizing template is to be used as a guide in cutting the bio-compatible material to form the heart patch, wherein each sizing template has a slot on one surface of the sizing template, and wherein the slot is concentric to the shape of the sizing template for allowing tracing of a suture line on the bio-compatible material;
a handle, wherein each sizing template is adapted to be coupled to the handle;
an expandable shaper configured to be expanded to 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 in the left ventricle during the reconstructive surgery;
a source for inflating the expandable shaper; and
a suture hook.
8. The kit of claim 7 , wherein the source for inflating the expandable shaper is a syringe coupled to the shaper.
9. The kit of claim 7 , wherein the expandable shaper comprises elastomeric material.
10. The kit of claim 7 , wherein the expandable shaper is configured to be expanded with a fluid.
11. The kit of claim 7 , further comprising a pressure transducer, wherein the pressure transducer is configured to monitor a pressure inside the expandable shaper.
12. The kit of claim 7 , further comprising a patch holder, wherein the patch holder is configured to place the heart patch on the heart, and wherein the patch holder is configured to be removed after suturing of the heart patch has begun.
13. A pre-fabricated, sterile kit for use during left ventricle reconstructive surgery to provide tools and apparatus to interoperatively construct a heart patch, reconstruct a left ventricle, and close an incision using the heart patch, the kit comprising:
bio-compatible material having markings, wherein the markings are configured in distinct patterns for post operatively evaluating the movement of the heart patch;
a series of sizing templates differing in size in which a surgeon can selectively position one such sizing template at or in an opening in the left ventricle, wherein the one such sizing template is to be used as a guide in cutting the bio-compatible material to form the heart patch, wherein each sizing template has a protrusion on one surface of the sizing template, and wherein the protrusion is concentric to the shape of the sizing template to create a suture line on the bio-compatible material when the protrusion is pressed against the bio-compatible material;
a handle, wherein each sizing template is adapted to be coupled to the handle;
an expandable shaper configured to be expanded to 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 in the left ventricle during the reconstructive surgery;
a source for inflating the expandable shaper; and
a suture hook.
14. The kit of claim 13 , wherein the source for inflating the expandable shaper is a syringe coupled to the shaper.
15. The kit of claim 13 , wherein the expandable shaper comprises elastomeric material.
16. The kit of claim 13 , wherein the expandable shaper is configured to be expanded with a fluid.
17. The kit of claim 13 , further comprising a pressure transducer, wherein the pressure transducer is configured to monitor a pressure inside the expandable shaper.
