    Abstract: 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 pins are adapted to be received by the passages defined by the ends of the first rigid member and of the second rigid member so as to secure the first rigid member in a spaced and generally parallel relationship to the second rigid member. The penis is positioned between the first and second members so that the underside of the penis is in contact with the second member and the top surface of the penis is in contact with the first member, thereby stopping involuntary voiding of urine. A clamp kit includes a plurality of pins of different width to vary the force applied to the penis.

  • Publication number: 20040094162
    Abstract: Certain embodiments include a method of improvising radiological outcomes by introducing a filler to between a first tissue location and a second tissue location to increase a distance between the first tissue location and the second tissue location, and administering a dose of radioactivity to at least the first tissue location or the second tissue location. Collagen and hyaluronic acid are examples of fillers. Certain embodiments include a medical device having a biocompatible, biodegradable filler material, wherein the device comprises at least a portion that has a shape that substantially conforms to Denovillier's space between the rectum and prostate. Certain embodiments include a kit, the kit comprising a filler and instructions for placing the filler between a first tissue location and a second tissue location to increase a distance between the first tissue location and the second tissue location.

  • Publication number: 20040045554
    Abstract: A vaso-occlusive device includes a microcoil formed into a minimum energy state secondary configuration comprising a plurality of curved segments, each defining a discrete axis, whereby the device, in its minimum energy state configuration, defines multiple axes. In a preferred embodiment, the minimum energy state secondary configuration comprises a plurality of tangentially-interconnected, substantially circular loops defining a plurality of discrete axes. In an alternative embodiment, the minimum energy state secondary configuration defines a wave-form like structure comprising a longitudinal array of laterally-alternating open loops defining a plurality of separate axes. In either embodiment, the device, in its minimum energy state secondary configuration, has a dimension that is substantially larger than the largest dimension of the vascular site in which the device is to be deployed.

  • Patent number: 6550480
    Abstract: Disclosed are occluders and methods of their use. The occluders comprise shape-memory polymeric materials which, when heated above their crystalline melting temperatures, may be deformed from a first configuration into a second configuration. The occluder is then held in the deformed shape until it cools to a temperature below its crystalline melting temperature (Tm) whereby it holds the deformed shape of the second configuration by virtue of the recrystallization of the polymeric occluder material. Upon reheating the occluder above its Tm, the occluder will resume its original shape. In this manner, an occluder which has been deformed to reduce its diameter may be inserted into and positioned within a target lumen in the body and then allowed to warm to body temperature whereby it resumes its original diameter and results in the occlusion of the lumen. The occluders, according to preferred embodiments, may be used for reversible sterilization of mammals, among other surgical and non-surgical uses.

  • Publication number: 20030029457
    Abstract: 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.

  • Publication number: 20030015203
    Abstract: A method of introducing continuous lengths of filament into the body in surgical procedures in which it is desirable to place a significant amount of material into the body through a small portal. The material so introduced may serve to bulk a tissue or cavity of the body or to occlude a vas, as well as to introduce diagnostic or therapeutic agents into a site in the body. A device for implementing the method has a mechanism for feeding the filament through a conduit in such a manner that sufficient force is applied to the filament that it is forced into the desired site. In one embodiment, a system of reciprocating cannulae and synchronized grippers is used to supply the requisite force to the filament.

  • Patent number: 6035854
    Abstract: Securement of a condom to the glans penis is facilitated by a molded, contoured, or thickened wedge portion which fits snugly within the cleft of the glans such that a continuous circumferential seal may be obtained about the glans penis. An expansible seminal reservoir is provided and the shaft of the penis, as well as the rear portion of the glans penis opposed to the cleft, may be left unsheathed in order to allow greater sensitivity. A greater wall thickness than that typically utilized in a full length condom may be used without significant loss of sensitivity and a stronger condom more resistant to tearing during use than a conventional full length latex condom is obtained. An adhesive backing with a tab allows location of the device prior removal of the backing to ensure correct positioning and an effective circumferential seal with the adhesive.

  • Patent number: 5976162
    Abstract: This is a micro-vaso-occlusive device intended generally for occlusion of small arteries located distally in the vasculature. The device is made up of a binder, often radio-opaque, which may be short in length by comparison to the length of the included thrombogenic fibers. The fibers form the other portion of the device. At least one end of the device includes a solid but comparatively soft end typically made of a molten mass of the fibers. The micro device may have multiple binder sections. The fibers may be straight, looped, or tufted.
