Description

BACKGROUND

Technical Field

The present disclosure generally relates to a male contraceptive device, and more particularly, to internal urethral condoms and methods of using the same.

Description of the Related Art

A condom is a physical barrier that conforms to the shape of a penis that acts as a barrier during sexual intercourse to reduce the probability of pregnancy and/or a sexually transmitted disease (STD). In additional to dramatically reducing the probability of pregnancy, it also can substantially reduce various diseases such as HIV/AIDS, Chlamydia, gonorrhea, hepatitis B, trichomoniasis, etc. Known condoms are generally in the shape of an external sheath around an erect penis, referred to herein as a traditional condom. Although generally effective in purpose, known condoms are often rejected because partners may not experience sufficient physical association during sexual intercourse due to the physical membrane in between. Further, traditional condoms may slip during a moment of loss of erection, thereby leading to the very dangers it is intended to avoid. While more modern solutions exist, they typically do not include an adequate combination of effectiveness against pregnancy, physical sensation between partners, protection against STDs, and spermicidal protection. It is within these considerations and others that this application has been written.

SUMMARY

According to one embodiment, an intraurethral contraceptive device includes an insertion tool and a urethral sleeve inside the insertion tool. The urethral sleeve includes a balloon on an outer surface and a distal proximal end of the urethral sleeve, having an air lumen that extends to a distal end of the urethral sleeve. There is an inside reservoir at a distal end of the sleeve, configured to capture any fluid traveling from the proximal end to the distal end of the urethral sleeve. An insertion plunger is coupled to a plunger head. The insertion plunger is configured to be placed inside a distal end of the insertion tool.

In one embodiment, insertion tool is constructed of a rigid polyurethane and is substantially cylindrically shaped.

In one embodiment, the insertion tool includes a circumferential protruding member on an outer surface of the insertion tool configured to stop an insertion of the insertion tool into a urethra beyond a predetermined distance.

In one embodiment, the balloon of the urethral sleeve is replaced by soft cups. The urethral sleeve includes soft cups that retain the urethral sleeve in the urethra. In an additional embodiment the urethral sleeve includes both a balloon and soft cups that retain the urethral sleeve in the urethra.

In one embodiment, the insertion tool is configured to compress the balloon. The balloon may be pre-inflated.

In one embodiment, the insertion tool is configured to compress the soft cups. In another embodiment, the urethral sleeve is sufficiently allowing its insertion without an insertion tool.

In one embodiment, the proximal end of the urethral sleeve is more rigid than its distal end. A rigidity of the proximal end is sufficient to prevent the balloon from narrowing a diameter of an opening (e.g., tract) of the urethral sleeve below a predetermined threshold.

In one embodiment, the balloon is pre-inflated in the insertion tool.

In one embodiment, the air lumen is sealed at the distal end of the urethral sleeve. The seal of the air lumen may be by way of adhesion to an outer wall of the urethral sleeve.

In one embodiment, the air lumen is configured to inflate the balloon to a predetermined pressure and to deflate the balloon upon a trigger. The trigger to deflate the balloon through the air lumen may be by way of a pullable tab at a distal end of the urethral sleeve.

In one embodiment, the insertion plunger includes a spring configured to push the insertion plunger back to an original position after a deployment of the urethral sleeve in the urethra.

In one embodiment, the proximal end of the insertion plunger abuts the distal end of the urethral sleeve inside the insertion tool.

In one embodiment, the insertion plunger is configured to slidingly release a proximal portion of the urethral sleeve including the balloon from a proximal end of the insertion tool into the urethra by a predetermined distance.

In one embodiment, there is a vasodilator inside the insertion tool.

According to one embodiment, a method of administering an intraurethral contraceptive device having an insertion tool, a urethral sleeve inside the insertion tool, and an insertion plunger at a distal end of the insertion tool is provided. The method includes slidingly inserting the insertion tool into a urethra. A proximal portion of the urethral sleeve including a balloon is released from a proximal end of the insertion tool into the urethra. The insertion tool together with the insertion plunger is slidingly removed from the urethra. Any fluid traveling from the proximal end to the distal end of the urethral sleeve is caught by a reservoir coupled to a distal end of the urethral sleeve. The balloon is deflated, and the urethral sleeve removed from the urethra.

In one embodiment, a predetermined distance that the insertion tool can be inserted into the urethra is controlled by a circumferential protruding member on an outer surface of the insertion tool.

In one embodiment, the balloon expands upon releasing the proximal portion of the urethral sleeve into the urethra.

In one embodiment, the balloon is pre-inflated in the insertion tool.

In one embodiment, releasing of the proximal portion of the urethral sleeve includes slidingly reducing a distance between a plunger head of the insertion plunger and the distal end of the insertion tool, by a predetermined distance.

In one embodiment, deflating the balloon comprises pulling a tab at a distal end of the urethral sleeve, operative to open a seal of an air lumen leading to the balloon.

By virtue of the devices and methods discussed herein, in addition to preventing pregnancy, the spread of sexually transmitted diseases (STDs) can be substantially suppressed by preventing the escape of bodily fluids that may include, without limitation, human papilloma virus (HPV), Herpes simplex virus (HSV), Human immunodeficiency virus (HIV), Monkey pox, poliovirus, etc. These benefits are provided while maintaining full sensation between sexual partners.

The techniques described herein may be implemented in a number of ways. Example implementations are provided below with reference to the following figures.

Example Components of a Urethral Condom

FIG. 1 illustrates an example male intraurethral contraceptive system (ICS) 150, consistent with an illustrative embodiment. The ICS 150 includes a urethral sleeve 100, sometimes referred to herein as a catheter, having a first (e.g., proximal) end 116 and a second (e.g., distal) end 118 that are configured to prevent any fluids from being released from the second end 118. In various embodiments, the urethral sleeve 100 may comprise rubber, latex, silicone, TPE, and/or any other suitable material that provides sufficient flexibility and durability to be inserted and kept in a urethra for a prolonged period of time. In one embodiment, the urethral sleeve 100 also comprises a distal urethral stop configured to prevent the distal end of the urethral sleeve from passing beyond the fossa navicularis when inserted. For example, the cavernous portion of the urethra may be narrow, and of uniform size in the body of the penis (e.g., measuring about 6 mm in diameter and can stretch to 8 to 9 mm in diameter.) It is dilated anteriorly within the glans penis, where it forms the fossa navicularis urethrae which may be 10-11 mm diameter.

In one embodiment, the first end 116 is made more rigid than the second end 118. For example, the rigidity of the proximal end of the urethral sleeve 100 is sufficient to prevent the balloon from narrowing a diameter of an opening (e.g., tract) of the urethral sleeve below a predetermined threshold.

There is a balloon 104, sometimes referred to herein as a bladder, on an outer surface of the urethral sleeve 100. In one embodiment, the balloon 104 circumferentially covers the outer surface of at least a portion of the first end 116. The balloon 104 includes an air lumen 106 that extends from the first end 116 to the distal end of the urethral sleeve. In one embodiment, the balloon 104 is pre-inflated with a fluid, such as air, nitrogen, etc., through the air lumen 106 to a predetermined pressure. The air lumen 106 is sealed 108 at the distal end of the sleeve, for example, by way of adhesion to the outer wall (e.g., surface) at the distal end of the urethral sleeve. The air lumen 106 can later also be used to deflate the balloon 104, as will be discussed in more detail below.

In an additional embodiment of the present invention, the balloon 104 may be inflated via a reaction between materials in the air lumen 106 that cause gas in the air lumen 106 to expand and fill the balloon 104. In this embodiment, the air lumen 106 houses a capsule 104a containing nitrogen gas. The remainder of the air lumen 106 is filled with a gas 106a that expands when it contacts nitrogen gas. Prior to insertion of the urethral sleeve 100 into the penis, the one breaks the capsule releasing the nitrogen gas into the air lumen 106 causing the nitrogen to activate the expandable gas 106a in the air lumen 106 to begin to inflate the balloon 104. The capsule 104a can be broken by bending the proximal end of the urethral sleeve 100. The urethral sleeve 100 can then be inserted into the penis prior to the balloon 104 fully inflating. One will wait a predetermined time prior to intercourse before the balloon 104 is fully inflated. Following intercourse, the seal 108 of the air lumen 106 is released, and the urethral sleeve 100 can be removed. The seal 108 may be form by a tab 306 or no tab may be required. One of skill in the art would understand the invention includes the use of other gases and materials that when combined will cause the gases in the air lumen 106 to expand and fill the balloon 104.

The air lumen 106 and the balloon 104 may be filled with a colored material 108a to indicate when the balloon 104 has been deflated. In this embodiment, once the seal 108 is broken, the fluid 108a exits the air lumen 106 indicating that the balloon 104 has deflated and it is safe to remove the ICS 150.

In one embodiment, the balloon 104 of the urethral sleeve is omitted and a sleeve retainer 105 is included on the outer wall of the urethral sleeve. In one example the sleeve retainer is a series of soft cups. The soft cups retain the urethral sleeve in the urethra. In another embodiment, the urethral sleeve includes both a balloon 104 and sleeve retainer 105 that retains the urethral sleeve in the urethra. The sleeve retainer 105 may act alone or in combination with other features that retain the urethral sleeve within the urethra. Examples of sleeve retainers include for example bumps, ridges, rings, seals. The sleeve retainer may be a balloon. The sleeve retainer 105 may hold the urethral sleeve in place while a separate seal prevents fluid from exiting the urethra while the urethral sleeve is inserted. In an embodiment, the insertion tool is configured to compress the sleeve retainer.

There is an inside reservoir 110 configured to capture any fluid traveling from the proximal end to the distal end of the urethral sleeve 100. For example, the inside reservoir 110 may capture the fluid by turning inside-out and expanding sufficiently to capture this fluid at the distal end of the urethral sleeve 100. In an embodiment of the invention, the reservoir 110 is permanently bonded to the urethral sleeve 100.

In an embodiment of the invention, a one-way valve 110a may be inserted into the proximal end of the urethral sleeve 100. The one-way valve 110a allows any fluid, traveling through the urethral sleeve 100 to enter the reservoir 110 while blocking any fluid from exiting the urethral sleeve 100.

In an embodiment shown in FIG. 9, the reservoir 110 is affixed to the distal end of the urethral sleeve 100. The reservoir 110 may be affixed to the urethral sleeve 100 by an adhesive. The air lumen 106 has an opening 109 into the urethral sleeve 100 inward from the distal end of the sleeve 100. When the reservoir 110 is in its initial position prior to ejaculation, the reservoir forms a seal over the opening 109 to allow the balloon 104 to be inflated. The reservoir may be bonded over the opening 109 to form the seal. Following ejaculation, the reservoir fills and exits the urethral sleeve 100. When the reservoir 110 is pulled, the seal over the opening 109 is broken, the balloon 104 and air lumen 106 vent through the opening 109 deflating the balloon 104. The ICS 150 can then be safely removed.

By way of example only and not by way of limitation, the urethral sleeve 100 can have a length ranging from 3.5″ to 6.5″ and have a diameter at the first end 116 ranging from 2 mm to 6 mm (uninflated) to 10 mm when it is fully inflated. The second end 118 can remain constant in diameter ranging from 4 to 6 mm.

The urethral sleeve 100 is provided inside of an insertion tool 120 of the ICS 150. The insertion tool 120 can be cylindrically shaped, although other shapes, such as oval, are contemplated as well. The insertion tool 120 provides the structural integrity that is salient to be inserted into a urethra. The insertion tool 120 also provides the requisite compression of the pre-inflated balloon 104 of the urethral sleeve 100, such that the balloon 104 does not impede the sliding entry into a urethra. In various embodiments, the insertion tool 120 may comprise polyurethane or any other suitable material. In one embodiment, between the insertion tool and the urethral sleeve 100 there is a vasodilator, spermicidal, bactericidal, and/or virucidal lubricant.

The insertion tool 120 has a first (e.g., proximal) end and a second (e.g., distal) end, and configured to securely house the urethral sleeve 100 such that the balloon 104 is housed at the proximal end of the insertion tool 120. In one embodiment, the insertion tool 120 has a first protruding member 124, referred to herein as an insertion stop 124, at the distal end of the insertion tool 120. The insertion stop 124 can act as a physical barrier (i.e., stop) for the insertion of the insertion tool 120 into a urethra. In this regard, reference is made to FIG. 2, which provides cross section views 200 and 250 of an insertion tool 150 placed inside a urethra of a penis 204, consistent with an illustrative embodiment. Accordingly, the insertion tool 120 can be slidingly inserted into the urethra until the tip of the penis 204 abuts this insertion stop 124, thereby providing a physical barrier from further insertion into the urethra.

The proximal end of the insertion tool 120 may be coated with a lubricant 120a. In one embodiment, the lubricant 120a is initially solid to allow for easier insertion of the tool 120 into the urethra. After insertion of the tool 120, the lubricant 120a melts into a fluid lubricant to aid in the insertion of the ICS 150. In another embodiment, the tool 120 is lubricated with a natural or synthetic lubricant prior to insertion into the penis.

In one embodiment, the insertion tool 120 has a second protruding member 128, sometimes referred to herein as a plunger stop. The plunger stop 128 includes the function of a physical barrier from the insertion plunger 130 to be inserted more than a predetermined distance A.

The insertion plunger 130 is placed inside the insertion tool 120 from the distal end of the insertion tool 120. For example, after the insertion tool 120 is slidingly placed inside a urethra, the plunger head 132 can be pressed towards the plunger stop 128 of the insertion tool 120, such that the urethral sleeve is ejected inside a urethra (e.g., erect penis) by a predetermined distance A. The insertion plunger 130 has a first (e.g., proximal) end and a second (distal) end having a handle (i.e., plunger head 132). As shown in configuration 150 of FIG. 1, the proximal end of the insertion plunger 130 abuts the distal end of the urethral sleeve 100 inside the insertion tool 120.

As illustrated in cross section view 250 of FIG. 2B, by pressing the plunger head 132 of the insertion plunger 130 towards the plunger stop 128, a portion of the urethral sleeve 100 is slidingly pushed outside the proximal end of the insertion tool 120 by a predetermined distance A such that the balloon can expand inside the urethra of the individual wearing the contraceptive device, thereby providing an occlusion between passage of any fluid from the urethral sleeve. Such expansion of the balloon also anchors the urethral sleeve within the urethra so that the urethral sleeve remains anchored internally as the insertion device is withdrawn and/or once it is completely removed. In one embodiment, instead of pushing the plunger head 132 towards the plunger stop 128, the plunger stop 128 can be pulled towards the plunger head 132 by the distance A. Referring back to FIG. 1, in one embodiment, the insertion plunger 130 has a spring 136, which pushes the insertion plunger 130 back to its original position after the deployment of the urethral sleeve 100 in the urethra.

Thus, the insertion plunger 130 allows the urethral sleeve 100 to be inserted into a (e.g., erect) penis. The insertion plunger 130 can then be slidingly removed from the urethra of the erect penis, together with the insertion tool 120, by pulling the handle of the plunger stop 128 away from the urethra. In this regard, FIG. 3A provides a cross-section view 300 of a urethral sleeve 100 that is inside a urethra after the insertion tool is removed, consistent with an illustrative embodiment. The balloon 104 anchors and prevents the urethral sleeve 100 from sliding out during the removal of the insertion tool 120 together with the insertion plunger 130, thereby leaving the urethral sleeve 100 securely inside the urethra. In one embodiment, a stop at the distal end of the urethral sleeve can be configured to stop at the head of the glans penis and/or within the fossa navicularis (e.g., the expanded portion of the distal end of the male urethra) within the glans penis so that the stop is completely internalized and not visible externally.

FIG. 3B is a cross section view 350 of a urethral sleeve 100 after the reservoir 110 catching any fluids in the tract of the urethral sleeve 100, consistent with an illustrative embodiment. As illustrated in FIG. 3B, the reservoir 110 is external from the distal end of the urethral sleeve 100. In one embodiment, there is a tab 306 at the distal end of the urethral sleeve 100 that is configured to open the seal 108 of the air lumen 106, thereby deflating the balloon 104. In this regard, FIG. 4 illustrates a urethral sleeve 100 having a deflated balloon, consistent with an illustrative embodiment. In one embodiment, the tab 306 is operative to also remove the urethral sleeve from the urethra. Stated differently, the pulling force applied to the tab 306 is operative to not only deflate the balloon 104 but also remove the urethral sleeve 100 from the urethra. In yet another embodiment, a tab is not required; rather by virtue of pulling the reservoir 110 with sufficient force allows to open the seal of the air lumen 106 and deflate the balloon. In this way, the entire urethral sleeve can be efficiently and quickly removed from the urethra.

For a more detailed understanding of the concepts discussed herein, FIG. 5A provides a top 500, FIG. 5B a cross-section 520, and FIG. 5C a side view 530 of an example male intraurethral contraceptive system (ICS) discussed in the context of FIGS. 1 to 4 drawn at a scale of 3, consistent with an illustrative embodiment. FIGS. 6A and B provide perspective views from a proximal end 600A and a distal end 600B of the ICS of FIGS. 5, consistent with an illustrative embodiment. FIGS. 7A and B provide an exploded view of an example intraurethral contraceptive system, consistent with an illustrative embodiment. It will be understood that the FIGS. 5 to 7 are provided as a conceptual overview of an ICS, and that many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. In one aspect, the intraurethral contraceptive devices discussed herein can be used with an external and/or internal lubricant that is bactericidal, virucidal, and/or spermicidal. The lubricant can also be associated with a vasodilator to help maintain an erection.

Example Process

With the foregoing overview of the architecture of an ICS, it may be helpful now to consider a high-level discussion of an example process related thereto. To that end, FIGS. 8A-E presents a conceptual process 800 of administering an intraurethral contraceptive device, consistent with an illustrative embodiment. For discussion purposes, the process 800 is described in FIGS. 8A-E using components described in the context of the discussion of FIGS. 1 to 6.

In FIG. 8A, an intraurethral contraceptive device is shown having an insertion tool 120, a urethral sleeve inside the insertion tool 100, and an insertion plunger 130 at a distal end of the insertion tool. The insertion tool 120 is slidingly inserted into a urethra. In one embodiment, the insertion of the intraurethral device 100 into the urethra is stopped by an insertion stop 124 of the insertion tool 120.

In FIG. 8B, a proximal portion of the urethral sleeve 100 including a balloon 104 is released from a proximal end of the insertion tool 120 into the urethra. In one embodiment, the balloon is pre-inflated and expands upon release in the urethra, thereby anchoring the urethral sleeve 100 in the urethra. In various embodiments, the releasing of the proximal portion of the urethral sleeve 100 is by bringing a plunger head 132 of the insertion plunger 130 towards the plunger stop 128 of the insertion tool 120, by a predetermined distance, by either bringing the plunger head 132 to the plunger stop 128 and/or the plunger stop 128 towards the plunger head 132.

In FIG. 8C, the insertion tool 120 is slidingly removed from the urethra, together with the insertion plunger 132.

In FIG. 8D, any fluid traveling from the proximal end to the distal end of the urethral sleeve 100 is caught by a reservoir 110 coupled to a distal end of the urethral sleeve. In one embodiment, the reservoir 110 is initially within (i.e., inside) the urethral sleeve 100 and turns inside-out, thereby creating an external reservoir 110.

In FIG. 8E, the balloon is deflated. In one embodiment, the deflation of the balloon is by way of pulling a tab 306 at a distal end of the urethral sleeve, operative to open a seal of an air lumen leading to the balloon 104. In another embodiment, a separate tab is not necessary; rather, the deflation of the balloon 104 is facilitated by pulling the reservoir 110, which is operative to, in addition to catching fluids, to open a seal of an air lumen leading to the balloon 104 when pulled with sufficient force.

In one embodiment of the invention shown in FIG. 11, the ICS 150 may be used to collect a sample from humans and non-human animals. Referring to FIG. 11, an ICS 150 with a one-way valve 110a in the urethral sleeve 100 is first inserted into the penis prior to ejaculation. The balloon 104 may be either pre-inflated prior to insertion of the ICS 150 or may be inflated after insertion. The reservoir 110 of the ICS 150 is permanently bonded to the urethral sleeve 100 such that fluid entering the urethral sleeve 100 cannot escape. When one ejaculates, fluid travels into the urethral sleeve 100 through the one-way valve 110a and enters the reservoir 110. The fluid is thus trapped in the urethral sleeve 100 and reservoir 110. The seal 108 of the air lumen 104 is broken either by removal of a tab or other means. The ICS 150 is then removed, and it can then be placed in a container and shipped to a laboratory for testing.

In another embodiment of the invention, the ICS 150 can be used to ejaculate synthetic sperm using the pressure of sperm entering the reservoir 110. Synthetic sperm can be any material intended to represent an ejaculation. In an example, the reservoir 110 is orientated such that it is bonded to the interior wall of the urethral sleeve 100 at its midpoint and the closed end of the reservoir 110 is at the proximal end of the sleeve 100. The void in the sleeve 100 created by this orientation of the reservoir 110 can be filled with synthetic sperm and held in place by a cover tab 165. As sperm enters the reservoir 110 after ejaculation, the reservoir inverts in the urethral sleeve 100 and forces the synthetic sperm through the cover tab 165 and out of the ICS 150. In an alternative, the cover tab 165 is removed before intercourse and sperm forces the synthetic sperm out of the ICS 150.

In another example, the reservoir 110 is bonded to the interior wall of the urethral sleeve 100 at its distal end and the outer cavity of the reservoir 110 can be filled with synthetic sperm and held in place by a cover tab 165. As sperm enters the urethral sleeve 100 after ejaculation, the reservoir 110 collapses and forces the synthetic sperm through the cover tab 165 and out of the ICS 150. In an alternative, the cover tab 165 is removed before intercourse and sperm forces the synthetic sperm out of the ICS 150.

In another example, the reservoir 110 is bonded to the interior wall of the urethral sleeve 100 at its distal end and the outer cavity of the reservoir 110 can be filled with synthetic sperm and held in place by a cover tab 165. The reservoir 110 is formed from concentric segments 166 that can collapse upon each other in layers. As sperm enters the urethral sleeve 100 after ejaculation, the reservoir 110 collapses along the concentric segments 166 and forces the synthetic sperm through the cover tab 165 and out of the ICS 150. In an alternative, the cover tab 165 is removed before intercourse and sperm forces the synthetic sperm out of the ICS 150.
