Description

contraceptive medical device Cross-reference regarding related applications This application claims the benefit under Section 119(e) of the United States Act of U.S. Provisional Application No. 62/934,090 (filed November 12, 2019) and U.S. Provisional Application No. 63/019,884 (filed May 4, 2020), each application incorporated herein in its entirety for all purposes. Technology field The present invention relates to a contraceptive medical device, and in particular discloses an intravaginal medical device comprising a ring, an injection-molded guide, and a barrier. Effective contraceptive medical devices or medicines are in demand globally for people of childbearing age. The success rate of contraceptive medical devices depends not only on the efficacy of the contraceptive method but also on user preference, the reversibility of the medical device or medicine, user convenience, and user compliance. The need for effective contraceptive methods, including medicines or medical devices, remains a significant requirement. It is estimated that 50% of pregnancies are unintended, and globally, a woman dies every two minutes due to pregnancy and childbirth-related complications. Hormone-based contraceptives have been widely used, but they are currently known to have systemic effects on the user and are contraindicated in individuals with various cardiovascular diseases. Therefore, it is desirable to provide a new and improved contraceptive medical device that provides local administration of an activator and is easier to use than existing devices and methods. Accordingly, there is a need to prevent pregnancy by providing a contraceptive medical device that allows for the local administration of one or more activators, is biocompatible, non-invasive, cost-effective, reversible, and convenient. The present disclosure provides a contraceptive medical device and related devices and methods to meet these needs. The exemplary features, nature, and various advantages of the present disclosure will become apparent from the following detailed description of various embodiments and the accompanying drawings. Non-limiting and incomplete embodiments are described with reference to the accompanying drawings, wherein similar labels or reference numbers refer to similar parts throughout the various drawings unless otherwise specified. The size and relative position of elements in the drawings are not necessarily drawn to scale. For example, the shape of various elements is selected, enlarged, and positioned to improve readability. The specific shape of the drawn elements is selected so that they are easily recognizable in the drawings. One or more embodiments are described below with reference to the accompanying drawings, where: FIG. 1 illustrates a plan view of an exemplary contraceptive medical device disclosed herein, illustrating an injection molding guide (1), a porous barrier (2), and a ring structure (3). FIG. 2 illustrates a schematic side view of a part of an exemplary contraceptive medical device disclosed herein, more specifically the part identified as “A” in FIG. 1, where FIG. 1 illustrates an injection molding guide (1), a porous barrier (2), and a ring structure (3). FIGS. 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, and 3i each illustrate cross-sectional views of a schematic portion of an exemplary injection molding guide (1) provided on a porous barrier (2) of a structure disclosed herein. FIG. 4 illustrates a schematic diagram of an exemplary injection molding guide (1) provided on a porous barrier (2) of an exemplary contraceptive medical device disclosed in this specification. FIGS. 5a and 5b each illustrate schematic diagrams of an exemplary injection molding guide (1) provided on a porous barrier (2) of an exemplary contraceptive medical device disclosed herein. FIGS. 6a, 6b, and 6c illustrate schematic diagrams of an exemplary structure, wherein FIG. 6a provides a plan view of the structure, FIG. 6b shows a full cross-sectional view of the structure of FIG. 6a as seen through line B shown in FIG. 6a, and FIG. 6c shows a partial cross-sectional view of the structure of FIG. 6a, specifically showing a part of the cross-sectional view enclosed within the area marked C in FIG. 6b. The present specification discloses a contraceptive medical device, also known as a contraceptive device, methods for manufacturing and using a contraceptive device, and structures useful for manufacturing a contraceptive device.
