Abstract
A wound spacer device comprising multiple beads connected by non-absorbable suture material is disclosed. The device can be applied, for example, by a first responder to an injured individual, or can be applied by a trauma treatment facility, such as a Level 2 medical unit. In typical embodiments the device allows for site-specific controlled elution of an antimicrobial agent, such as Tobramycin, including defined elution over a period of time, such as 48 or 72 hours.

A removable wound spacer packing device, said wound spacer packing device comprising:
- a plurality of beads arranged along a flexible polyamide connector material, each of said beads comprising:
- a polyamide core;
- a first layer outside said core, said first layer containing a bioactive agent and a polymeric material derived from poly[vinylpyrrolidone];
- a second layer outside said first layer, said second layer comprising poly(butylmethacrylate) and poly(ethylene-co-vinyl acetate);
- a third layer outside said first layer, said third layer comprising poly(butylmethacrylate).
A removable wound spacer packing device, said wound spacer packing device comprising:
- a plurality of beads arranged along a flexible polyamide connector material, each of said polyamide beads comprising:
- a polyamide core containing barium sulfate;
- a first layer outside said core, said first layer containing a bioactive agent and a polymeric material derived from poly[vinylpyrrolidone];
- a second layer outside said first layer, said second layer comprising a material derived from poly(butylmethacrylate), poly(ethylene-co-vinyl acetate), poly(vinyl pyrrolidone), and tetrakis(4-benzophenylmethoxymethyl)methane;
- and
- a third layer outside said first layer, said third layer comprising poly(butylmethacrylate).
A kit for treating a wound, the kit comprising:
- at least two removable wound spacer packing devices, each of said wound spacer packing devices comprising a plurality of beads arranged along a flexible polyamide connector material, each of said polyamide beads comprising:
- a polyamide core containing barium sulfate;
- a first layer outside said core, said first layer containing a bioactive agent and a polymeric material derived from poly[vinylpyrrolidone];
- a second layer outside said first layer, said second layer comprising a material derived from poly(butylmethacrylate), poly(ethylene-co-vinyl acetate), poly(vinyl pyrrolidone), and tetrakis(4-benzophenylmethoxymethyl)methane;
- and
- a third layer outside said first layer, said third layer comprising poly(butylmethacrylate);
- and
- a retaining device for holding the at least two removable wound spacer packing devices during storage and prior to application to a wound.
