    Abstract: P6072914NL 11 Abstract A heart support device for circulatory assistance is disclosed. The device comprises a chamber body (10) defining a chamber having an internal volume configured to be filled with blood. The chamber 5 body (10) has a first opening (12) and the chamber is dimensioned such that the first opening (12) and the chamber are fully disposed within a chamber of the human heart. A dynamic volume body (14) is provided and configured to be inflated or deflated to alternately increase or decrease the interior volume ofthe chamber. A catheter (16) comprising at least one lumen in fluid communication with the dynamic volume body is configured to deliver fluid to the dynamic volume body to inflate the dynamic volume 10 body. A directional fiow structure is configured to direct a flow of blood out of the chamber in a direction substantially aligned with a direction in which the catheter (16) extends.

    Abstract: The invention relates to a process for making an oligo(alkylene glycol) functionalized co-polyisocyanopeptide, wherein the process comprises the steps of: i) copolymerizing - a first comonomer of an oligo(alkylene glycol) functionalized isocyanopeptide grafted with a linking group and - a second comonomer of a non-grafted oligo(alkylene glycol) functionalized isocyanopeptide, wherein the molar ratio between the first comonomer and the second comonomer is :500 and 1:30 and ii) adding a reactant of a spacer unit and a cell adhesion factor to the copolymer obtained by step i), wherein the spacer unit is represented by general formula A-L-B, wherein the linking group and group A are chosen to react and form a first coupling and the cell adhesion factor and group B are chosen to react and form a second coupling, wherein the first coupling and the second coupling are independently selected from the group consisting of alkyne-azide coupling, dibenzocyclooctyne-azide coupling, oxanorbornadiene-based-azide couplings, vinylsulphone-thiol coupling, maleimide-thiol coupling, methyl methacrylate-thiol coupling, ether coupling, thioether coupling, biotin- strepavidin coupling, amine-carboxylic acid resulting in amides linkages, alcohol- carboxylic acid coupling resulting in esters linkages and NHS-Ester (N- Hydroxysuccinimide ester)-amine coupling and wherein group L is a linear chain segment having 10-60 bonds between atoms selected from C, N, O and S in the main chain.
