Abstract:
1. An intravaginal contraceptive device, comprising: a biocompatible polymeric support structure configured to be inserted into a woman's vagina, the support structure constructed, configured and formed of materials such that the structure is capable of biocompatibly remaining in a woman's vagina for three days without dissolving completely; the support structure impregnated with a non-hormonal composition comprising ascorbic acid in an effective amount to increase the viscosity of cervical mucus and a contraceptively effective amount of ferrous gluconate or ferrous-sulfate, the device configured and formed with biodegradable materials so that when inserted into the vagina the ascorbic acid and ferrous gluconate or ferrous sulfate are released via degradation of the biodegradable materials of the device, to contraceptively reduces sperm mobility and contraceptively increases cervical mucus to impeded sperm mobility and the device includes a releasable pH limiting component to maintain a pH in the vaginal cavity at a spermiostatic level; the support structure with the composition disposed therein constructed and formed with materials effective to break down when present within the vagina and provide sustained release of a contraceptively effective amount of the composition for three days.
