摘要:
An attachment mechanism for a surgically implantable medical device includes one or more fasteners which may be simultaneously moved from an undeployed position to a deployed position by operation of an integral actuator. The attachment mechanism may be configured to be deactuated, and the fasteners simultaneously moved from a deployed position to an undeployed position, allowing removal or repositioning of the medical device. An applier includes a locator for detachably holding the implantable medical device, locating it at the desired position, and actuating the attachment mechanism. The applier is configured to undeploy the attachment mechanism the implantable medical device can be detached from the body tissue.

A method of repositioning an injection port comprises positioning the injection port at a first location in a patient's body and extending fasteners of the injection port to substantially secure the injection port at the first location. The fasteners are then retracted to substantially unsecure the injection port from the first location in the patient's body. The injection port is then moved to a second location in the patient's body. The fasteners are then re-extended to substantially secure the injection port at the second location in the patient's body. The injection port includes a port body. The fasteners are integral with the port body. The fasteners may be selectively extended and retracted relative to the port body. For instance, the fasteners may be pivoted relative to the port body to transition between extended and retracted positions. The extension and retraction of fasteners may be provided through a port applier.

An injection port comprises a body, a fluid reservoir, a septum, and a plurality of fasteners. The fluid reservoir is defined in part by the body and the septum. A needle may be inserted through the septum to reach the reservoir. The fasteners are integral with the body. The fasteners are simultaneously rotatable from a non-deployed position to a deployed position. The fasteners are retracted relative to the body when the fasteners are in the non-deployed position. The fasteners are extended relative to the body when the fasteners are in the deployed position. The fasteners are also simultaneously rotatable from the deployed position to the non-deployed position. The injection port may be coupled with a gastric band via a conduit. The conduit may provide fluid communication between an inflatable member of the gastric band and the reservoir of the injection port as part of a closed fluid circuit.

A self attaching injection port has integral moveable fasteners which are moveable from a undeployed state to a deployed state engaging tissue. The fasteners may be disposed radially or tangentially, and rotated to pierce the fascia. The fasteners may be rigid or elastically deformable.

A rotational locking mechanism for securing a catheter to a surgical implant is disclosed. The locking mechanism includes a deflectable extension extending from the surgical implant about the catheter attached to the surgical implant. The shape of the deflectable extension defines a slot therein. A connector having at least one tab extending therefrom is placed about the catheter at the point of attachment to the surgical implant. Rotation of the tubular connector brings at least one tab of the connector into contact with the slot in the deflectable extension and deflects and releases at least a portion of the slot as the connector rotates from an unlocked position to a locked position within the slot. The rotation motion secures the catheter to the surgical implant, and produces a feedback detectable by a surgeon rotating the tubular connector.

An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. The elongated member has a compressible ventral surface and a substantially rigid dorsal periphery, wherein the elongated member includes a fluid bladder positioned along the ventral surface. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. Alternate embodiments are also disclosed.

An injection port applier is configured to engage an injection port that has integral fasteners that are movable from a non-deployed position to a deployed position. The applier comprises a shaft, a port engagement portion, and a handle. The port engagement portion is includes a fastener deployment member that is operable to move the fasteners to the deployed position. The handle comprises a first handle portion and a second handle portion. The second handle portion is movable distally relative to the first handle portion in order to actuate the fastener deployment member, to thereby move the fasteners to the deployed position. An elongate actuating member couples the second handle portion with the fastener deployment member. One part of the elongate actuating member translates longitudinally in response to the second handle being moved distally; while another part of the elongate actuating member rotates in response to the first portion translating.
摘要:
An apparatus for regulating the functioning of a patient's organ or duct. The apparatus includes an elongated member having first end and second ends. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a ring around the organ or duct. A tension element is slidably disposed within the elongated member. A drive element is associated with and engaging the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. An antenna/controller pod is releasably coupled to the elongated member for control of the drive element.
