Abstract:
Methods for removing a biomaterial implant and reversing occlusive effects of the biomaterial implant are described. In particular, methods for performing removal of biomaterial implants without damage to a body lumen where the biomaterial was previously implanted are presented. More specifically, methods of reversing an implant within a vas deferens using an ablation device are described.
Abstract:
Disclosed herein are exemplary medical devices for controlled delivery of material compositions, particularly occlusive, therapeutic, or diagnostic compositions.
Abstract:
Formulations, kits and methods for effecting contraception are disclosed. These formulations, kits and methods involve the delivery of progestins and estrogens in amounts personalized to the body weight and or the BMI of the women receiving the treatment.
Abstract:
A medical applicator for use in female sterilization of a fallopian tube using an occlusive plug comprises: an elongate probe for insertion into the womb of said female; means for delivery of fluid to a distil end of said probe; means for illuminating a region in front of said distil end of said probe; and viewing means for viewing in front of said distil end of said probe. The probe has a small outside dimension in the range 7mm or less, and a camera on integrated circuit chip at the distal end of the probe.
Abstract:
An intrauterine device for applying pressure to the walls of the uterine cavity includes a resilient body having an elongated member which includes a first end and a second end which are resiliently biased away from each other. The first end of the elongated member includes a first leg having a first end and a second end. The second end of the elongated member includes a second leg having a first end and a second end. A first plug member is secured at the second end of the first leg and a second plug member is secured at the first end of the second leg. The first and second plug members are shaped and dimensioned for bearing against the walls of the uterine cavity as the elongated member spreads outwardly with the first end and the second end moving apart. A method for preventing conception within the uterine cavity is also disclosed.
Abstract:
Transcervical pathway systems and methods are described. The system may include a delivery sheath having a first longitudinal opening and a second longitudinal opening. A visualization system, such as a hysteroscope, is deliverable through the first longitudinal opening of the delivery sheath. An implant delivery system is deliverable through the second longitudinal opening of the sheath. The implant delivery system may include a guide and an implant delivery system moveably (e.g. slideably) engaged with the guide.
Abstract:
Embodiments of the present invention provide systems and methods for delivering a contraceptive device to an ovarian pathway. The contraceptive device is within an enclosure in a first position. In a second position, the contraceptive device is positioned at the ovarian pathway, by actuating a first actuator. The contraceptive device is then expanded and released from the delivery system by actuating a second actuator.
Abstract:
A system and method of occluding a reproductive body lumen (34) to prevent the passage of reproductive cells through body lumen is disclosed. The system can include a catheter delivery system (10) having a handle device (18), a catheter (10) operatively coupled with the handle device (20), and an occluding device adapted for deployment within the body lumen. The handle device can include a damper device adapted to reduce the vibration on the handle device from deployment of the occluding device from the catheter. Further, the handle device can include an indexing member operatively coupled with the catheter to provide indexing of the catheter.
Abstract:
A device for occluding a target body lumen, comprises a wire structure (108) defining a wire structure lumen (116) extending therethrough and movable between a reduced diameter insertion configuration and an expanded diameter deployed configuration and a basket structure (104) extending across the wire structure lumen and including therein a cell growth promoting agent (106) to promote cell growth across the wire structure lumen to occlude the target body lumen.
Abstract:
The present invention is directed to a medical device for occluding a fallopian tube for contraception and sterilization. The medical device includes an outer member (12), an inner member (14) and a tissue growth member (16). The outer member includes an outer surface (20) and an inner surface (22), wherein the inner surface defines a bore (24) in the outer member. The inner member is configured to be positioned within the bore of the outer member. The tissue growth member is attached to the outer surface of the outer member and is configured to induce tissue growth thereto. With this arrangement, the medical device can be implanted within the fallopian tube and serve as an occluding device therein. If desired, the medical device can be partially removed from the fallopian tube to restore the ability for conception.
