Abstract: The present disclosure relates to hydrogels and their use for repairing or supplementing body tissue. The hydrogels are capable of safe injection into patients through fine gauge needles and are suitable for repairing, supplementing, or replacing the nucleus pulposus of an intervertebral disc. Methods of manufacturing and methods of using the hydrogels of the present disclosure to repair or replace tissues are also disclosed.

Abstract: The present invention is directed to a bioadhesive thermogelling hydrogel composition for repairing and/or augmenting an intervertebral disc. The bioadhesive thermogelling hydrogel composition can be cross linked with the surrounding tissue so as to potentially serve as a nucleus pulposus replacement or augmentation along with serving to repair annular tears or fissure. The bioadhesive thermogelling hydrogel composition may include three main components: a thermal responsive polymer, an amine-containing polymer and a crosslinking component. All three components can be modified and combined in numerous ways to serve the need of the system as long as the amine-containing component is kept separate from the crosslinking component until the components are injected. The incorporation of a two-part crosslinking thermal responsive hydrogel permits smaller amounts of the crosslinking component to be used and enables the crosslinking dialdehyde to be delivered locally into the tissue that will react with the hydrogel.

Abstract: A blood circulation assistance device (1), for location around a blood conduit (20). The device comprises: an inflatable bladder (10) moveable between a contracted form and an expanded form, for compressing the blood conduit (20) to provide counterpulsation. Pump means (30) in fluid communication with the bladder (10) move the bladder (10) from the contracted form to the expanded form. The pump means (30) comprises a centrifugal impeller (62) rotatable about an axis (61) to effect pumping. The impeller (62) is moveable axially between first and second positions to effect a reversal of the direction of pumping. Control means (50), in communication with the pump means, is capable of monitoring the cardiac cycle of an individual and triggering the pump means (30) to move the bladder (10) to the expanded form at diastole. An outer cuff, surrounds at least a portion of the bladder (10), providing an outer limiting extent to the movement of the bladder (10).
