DemeDiox Barbed

Polydioxanone Barbed Suture



Polydioxanone Barbed suture is indicated for use in soft tissue approximation where use of absorbable sutures is appropriate.




Two important characteristics describe the in vivo performance of absorbable sutures: first, tensile strength retention, and second, the absorption rate (loss of mass). POLYDIOXANONE Barbed synthetic absorbable suture has been formulated to minimize the variability of these characteristics and to provide wound support through an extended healing period. Data obtained from implantation studies in rats show that the absorption of these sutures is minimal until about the 90th post-implantation day. Absorption is essentially complete within seven to eight months.

Suture Material


POLYDIOXANONE monofilament synthetic absorbable suture is prepared from the polyester, poly (p-dioxanone). The empirical molecular formula of the polymer is

H  [  O   CH2CH2OCH2   C  ]n  OH



Polydioxanone polymer has been found to be non-antigenic and elicits only a slight tissue reaction during absorption. DemeTECH Polydioxanone Barbed USP designations for diameter are used to describe suture prior to barbing. After barbing, the suture is identified as one size smaller than non-barbed suture. SBS-PDO can be compared to USP knot strength of non-barbed sutures
