The present invention provides a system for improving diastolic function of the heart comprising elastic elements and attachment elements, wherein said elastic elements and said attachment elements are configured such that they are capable of being interconnected to form a chain formed of an alternating series of said elastic elements and said attachment elements, and wherein said attachment elements are adapted to be anchored in the wall of the heart and with option for drug delivery to the wall of the heart. The invention further provides devices, methods and kits, for mounting the ventricular function assisting device of the invention.

Method and system for improving diastolic function of the heart

This invention is a device () for sealing a hole () in a blood vessel (), comprising a blood vessel engager () having at least one spike (), for engaging a portion of a blood vessel () adjacent a hole in the blood vessel, and a body () coupled to the blood vessel engager (). The device () has at least two configurations, a first configuration in which the device does not seal the hole, and a second configuration to which the device can be changed so that the second configuration of the device seals the hole.

Vascular port device

An anastomotic connector for connecting a graft to a target vessel, comprising a thin collar section () adapted to engage a portion of the graft; and a separate spike section () adapted to mount on said collar section, and comprising a plurality of spikes () each of said spikes () adapted to transfix said graft. Preferably, the connector comprises at least one locking element for interlocking said spike section (), and said collar section (). Preferably the locking element provides a spring action between the two sections.

Vascular surgery

This invention is a device () for sealing a hole in a blood vessel, comprising a ring (); a plurality of spikes () extending from said ring towards a center of said ring, and to first direction along an axis of said ring, said spikes being adapted for engaging a blood vessel; a plurality of tabs () extending substantially radially from said ring, wherein rotating said tabs around said ring distorts said ring such that said spikes are rotated in a same direction as said tabs.

Vascular closure device

An anastomotic connector () for attaching two blood vessels, comprising a cylinder-like portion having a lumen, two ends, and an array of cells elements, and a tissue engaging portion () comprising at least one set of spikes () wherein at least one spike arranged adjacent one of the two ends of said cylinder-like portion. The connector () may comprise at least a second set of spikes () adjacent the other of the two ends.

Methods and devices for vascular surgery

An anastomosis connector comprises a plurality of ring segments (), together defining a radially expandable ring-like shape () having a lumen; at least one pivot bar () coupled to at least one of said ring segments (); at least one spike () mounted on said pivot bar () and rotatable around said pivot bar (), wherein radial deformation of said ring-like shape () does not substantially directly affect said spike () rotational position.

Low profile anastomosis connector

This invention is a hole closure device ( ) having at least two blood vessel engaging structures ( ), preferably spikes, each comprising a base ( ), at least one second, deformable structure ( ) coupled to said at least two blood vessel engaging structures ( ), having a first deformation state, and a second deformation state; wherein said at least one second deformable structures ( ) urges said two blood vessel engaging structures ( ) towards each other when going from said deformation state to said second deformation state; wherein said change in deformation state is at least partially mechanically decoupled from each of said blood vessel engaging structures ( ).
