In at least one embodiment, an implantable restraining device of the present disclosure comprises a first engaging component and a second engaging component, the first and second engaging components configured for laparoscopic insertion into a body cavity, and at least one connector coupled to the first engaging component and the second engaging component, the at least one connector capable of comprising a first configuration relative to the first engaging component and the second engaging component whery the first engaging component and the second engaging component are positioned relative to one another to fit within a laparoscopic port, the at least one connector capable of comprising a second configuration relative to the first engaging component and the second engaging component whereby the first engaging component and the second engaging component are spaced apart from one another so that an interior space having a value is defined therebetween.
Abstract:
Devices, systems, and methods for accessing the internal and external tissues of the heart are disclosed. At least some of the embodiments disclosed herein provide access to the external surface of the heart through the pericardial space for localized delivery of leads to the heart tissue. In addition, various disclosed embodiments provide devices, systems, and methods for closing a hole in cardiac tissue.
Abstract:
Devices, systems, and methods for accessing tissue, including the internal and external tissues of the heart, are disclosed. At feast some of the embodiments disclosed herein provide access to the tissues surrounding the heart to facilitate myocardial infarct healing and border zone reinforcement. In at least one embodiment, a suction/infusion catheter is used to provide localized suction to an area of myocardial infarct. In another embodiment, a suction infusion catheter is used to deliver a glue-like substance and magnetic cells to a myocardial infarct border zone.
Abstract:
Systems and methods for remodeling the annulus of a valve are disclosed. At least some embodiments disclosed herein are useful for resizing the mitral valve annulus in a safe and effective way. Such remodeling can be used to treat mitral valve regurgitation. At least some of the disclosed embodiments adjust the size of a valve annulus using magnetic forces. Other embodiments may include mechanisms for the manual adjustment of the annulus.
Abstract:
The disclosure of the present application includes assemblies, systems, and methods for preventing endoleak and migration. In an embodiment of an assembly for delivering a magnetic glue-like substance, the assembly comprises a catheter defining a catheter, a needle positioned within the catheter, and a needle wire, whereby a magnetic glue-like substance may be injected through a needle wire to a target site.
Abstract:
A device for supporting a tissue, the device has a shaft having a longitudinal axis and at least two atraumatic clamps coupled to the shaft. Each atraumatic clamp may have at least two oppositely polarized magnets. An atraumatic clamp may also have a mounting structure for the magnets. In at least one embodiment, the atraumatic clamps are mounted along the shaft so that when the shaft is positioned relative to a tissue having a length, the clamps may clamp the tissue so that the length of tissue positioned between the clamps is maintained substantially constant.
Abstract:
Devices and methods are disclosed for repairing a heart chamber, particularly useful for those who have suffered damage from myocardial infarction. A balloon is disclosed aimed at changing the shape of the volume of blood flow through a chamber of the heart from a spherical shape to a natural elliptical shape. This balloon has a magnetic outer wall which communicates with magnets on the outside of the chamber to form supports.
Abstract:
The disclosure of the present application provides devices, systems, and methods for the prevention of stroke. In at least one embodiment of a device of the present application, the device comprises an extension portion sized and shaped to fit within an artery extending from an aortic arch, and a flange portion sized and shaped to prevent the device from advancing into the artery extending from the aortic arch in which the device may be positioned. In at least one embodiment of a system for preventing stroke of the present application, the system comprises a hypotube, a folder coupled to a distal end of the hypotube, a sleeve positioned circumferentially around the hypotube proximal to the folder, and a stent, wherein a first part of the stent may be positioned within the folder, and wherein a second part of the stent may be positioned within the sleeve.
Abstract:
Devices, systems and methods for performing a minimally invasive endoscopic surgery without the use of sutures or staples. A device and system are described that are capable of isolating at least one targeted tissue and forming an anastomosis between two internal body structures through a completely endoscopic procedure. Further, the device and system described generally comprise two tubular members that are capable of moving in a telescopic fashion relative to one another. Additionally, a method is described for using the device and/or system to bypass the duodenum from digestion.
