Abstract
A system has been developed for injecting a biodegradable pericardial constraint including: a biodegradable viscoelastic substance (BES); an external injection container for the BES; a cannula having a distal section adapted to be inserted into a pericardial sac of a mammalian heart and a proximal section connectable to the external injection container; wherein BES from the injection container is injected into the pericardial sac through the cannula.
Claims35
A system for injecting a biodegradable pericardial constraint comprising:
- a biodegradable viscoelastic substance (BES);
- an external injection container for the BES;
- a biocompatible sealant;
- an external injection container for the sealant;
- a cannula having a distal section adapted to be inserted into a pericardial sac of a mammalian heart and having a proximal section connectable to the external injection container, and
- wherein BES from the injection container is injected into the pericardial sac through the cannula in an amount sufficient to constrain the heart to achieve a therapeutic effect and the sealant is injected into the pericardial sac through the cannula in an amount sufficient to seal an aperture formed in the pericardial sac after injection of the BES.
A method comprising:
- inserting a cannula through a transpericardial incision and into a pericardial space of a heart of a mammalian patient,
- connecting a delivery system containing a biodegradable viscoelastic substance to the cannula;
- injecting the biodegradable viscoelastic substance injection into the pericardial space, and
- sealing the transpericardial incision after injection of the biodegradable viscoelastic substance.
A treatment system for a biodegradable pericardial constraint comprising:
- a cannula placed in a pericardial space of a heart of a mammalian patient;
- an external system connectable to the cannula for delivery of a hydraulic heart constrainer in a controlled manner,
- a biodegradable viscoelastic substance (BES) to be delivered by the external system through a transpericardial incision to the pericardial space, wherein the BES constrains the heart constrainer when in the pericardial space, and
- a sealer applied to the transpericardial incision in the pericardial space.
A method to constrain a mammalian heart of a patient comprising:
- positioning a cannula through a transpericardial incision and into a pericardial sac of the heart;
- introducing a biodegradable viscoelastic substance (BES) though the cannula into the pericardial sac;
- extracting the cannula from the pericardial sac after introducing the BES,
- sealing the transpericardial incision, and
- decomposing the BES into the patient.
