The invention is drawn to silane copolymers prepared from the reaction of one or more polyisocyanates with one or more lubricious polymers having at least two functional groups, which may be the same or different, that are reactive with an isocyanate functional group and with one or more organo-functional silanes having at least two functional groups, which may be the same or different, that are reactive with an isocyanate functional group and at least one functional group reactive with a silicone rubber substrate. The silane copolymer coatings of the invention are elastic, lubricious, and resist wet abrasion. They are useful as coatings for polysiloxane (rubber) and other difficult to coat substrates, especially for medical devices, such catheters.

The invention described is directed to an intracorporeal occluding device having elements with non-traumatic ends and devices, systems and methods for occluding the lumens of anatomical passageways and / or for delivering drugs or other substances to the bodies of human or animal subjects.

A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory responses or to deliver a drug.

Male, hermaphroditic, and female condoms that exert lateral pressure on the penis and the vagina of a man and a woman respectively are disclosed. The lateral pressure is exerted by the geometry of the condoms themselves upon application or is exerted by means for exerting such lateral pressure located or applied on the condoms which means are normally activated by the user after the condoms are applied. User activated lateral pressure is controllable by the user within safe limits or, once activated by the user, is designed to be within safe limits. The lateral pressure retains the condoms securely in position to act as contraceptive and prophylactic barriers between the male and female genital areas, while increasing stimulation during intercourse.
