Abstract
A therapeutic delivery device comprises a layer of biodegradable material wound into a plurality of windings, the plurality of windings comprising an outermost winding defining an internal volume and winding pairs including a first winding pair and a second winding pair. A first therapeutic mass is incorporated in or on the layer the first winding pair and a second therapeutic mass is incorporated in or on the layer along the second winding pair. In one implementation, at least one volume of gas is captured within the internal volume and occupies at least 50% of the internal volume. In one implementation, the windings include perforations.
Claims19
A therapeutic delivery device taken orally or via implant comprising:
- a layer of biodegradable material wound into a plurality of windings, the plurality of windings comprising an outermost winding defining an internal volume and winding pairs including a first winding pair and a second winding pair, wherein the layer comprises a folded layer, the folded layer being wound into the plurality of windings;
- a first therapeutic mass incorporated in or on the layer along the first winding pair;
- a second therapeutic mass incorporated in or on the layer along the second winding pair;
- and
- at least one volume of gas captured within the internal volume and occupying at least 50% of the internal volume.
A therapeutic delivery device taken orally or via implant comprising:
- a layer of biodegradable material wound into a plurality of windings, the plurality of windings comprising an outermost winding defining an internal volume and winding pairs including a first winding pair and a second winding pair;
- a first therapeutic mass incorporated in or on the layer along the first winding pair;
- a second therapeutic mass incorporated in or on the layer along the second winding pair;
- at least one volume of gas captured within the internal volume and occupying at least 50% of the internal volume;
- and
- a spacer between the windings to form pockets containing the at least one volume of gas.
A therapeutic delivery device taken orally or via implant comprising:
- a layer of biodegradable material wound into a plurality of windings, the plurality of windings comprising an outermost winding defining an internal volume and winding pairs including a first winding pair and a second winding pair, wherein the layer comprises a first side having concave depressions containing the at least one volume of gas;
- a first therapeutic mass incorporated in or on the layer along the first winding pair;
- a second therapeutic mass incorporated in or on the layer along the second winding pair;
- at least one volume of gas captured within the internal volume and occupying at least 50% of the internal volume, wherein the layer comprises a second side opposite the first side, the second side having convex bumps corresponding to and opposite the concave depressions, wherein the concave depressions and the convex bumps of adjacent winding pairs are offset.
A therapeutic delivery device taken orally or via implant comprising:
- a layer of biodegradable material wound into a plurality of windings, the plurality of windings comprising an outermost winding defining an internal volume and winding pairs including a first winding pair and a second winding pair;
- a first therapeutic mass incorporated in or on the layer along the first winding pair;
