Abstract: An intrauterine device includes an elongate member; and a flexible arm having a first end and a second end, wherein the first end is operatively coupled to the elongate member at a first location, and wherein the second end is operatively coupled to the elongate member at a second location, and wherein the flexible arm is adjustable between a closed configuration, in which the flexible arm is closely apposed to the elongate member, and an open configuration, in which the flexible arm extends away from the elongate member, and wherein the flexible arm is biased to be in the closed configuration.

Abstract: Implants for placement in the fallopian tube are provided that comprise radiopaque material. Implants include an inner core of silicone, a radiopaque material, an outer porous portion surrounding the inner core, and, optionally, a sound-reflecting air pocket. The implant may be detected in a fluoroscopic image and/or via ultrasound after placement of the implant in the fallopian tube.

Abstract: Devices and methods are disclosed for the delivery of a compressible implant into a bodily lumen. The delivery device includes an enlarged section that is configured to house the implant during delivery thereof into a patient. In certain embodiments, the implant is kept within the delivery device in a substantially uncompressed configuration prior to the delivery thereof.

Abstract: Medical devices and related methods are disclosed for delivering an implant into the body of a patient. The devices include a damping assembly having an internal chamber with a varying inner diameter, and a piston slideably disposed therein. The piston is operably connected with a catheter portion such that movement of the piston is associated with concurrent movement of the catheter for implant delivery. The varying inner diameter of the damping assembly results in a decrease in damping force during implant delivery, thus providing a substantially constant velocity of implant delivery.

Abstract: An implant configured for insertion and placement within a fallopian tube of a female during a sterilization procedure. The implant includes an implant body having proximal and distal ends and a tether. The tether is attached to the implant body and extends a distance away from the implant body. The tether may be bioabsorbable and/or detachably coupled to the implant body so that the tether can be separated from the implant body without dislodging the implant body from the fallopian tube.

Abstract: Sterilization devices and methods for deploying porous implants within the fallopian tubes are disclosed. The devices include a catheter component including an external electrode sheath containing at least two deployable implants and a positioning member. Sliding the external sheath proximally disposes the implants within the fallopian tubes, while sliding both the positioning member and external electrode sheath distally reloads a second implant into the external electrode sheath. The devices further includes a handle component, which houses a chassis, external electrode sheath carrier, reciprocating shaft, positioning member carrier and first and second engaging members. The reciprocating shaft may be operated by a motor to slide distally and proximally along a long axis. The reciprocating shaft, external electrode sheath and its carrier, upon selective actuation, move together proportionally to deploy and reload the implants to facilitate occlusion of the fallopian tubes and complete sterilization.

Abstract: Devices and methods are disclosed for the delivery of an implant into small bodily spaces. The delivery devices include an expandable portion configured for placement within such bodily spaces and subsequent expansion to facilitate the delivery of the implant.

Abstract: A load sensor includes a housing and a magnet carrier axially movable within the housing. A first and a second magnet are coupled to the magnet carrier in an axially spaced apart arrangement and oriented to provide repelling magnetic fields. The magnet carrier and the first and second magnets are axially movable relative to the magnetic field sensor, and the magnetic field sensor is configured to provide an output that is indicative of the position of the magnetic filed sensor relative to the first and second magnets.

Abstract: A rotary magnetic position sensor including a housing, a sensor coupled to the housing, a rotor rotatably mounted to the housing, and a magnet coupled to the rotor and positioned adjacent the sensor. The sensor may be configured to provide a sensor output in response to a rotational position of the rotor relative to the housing.
