  • Patent number: 10213304
    Abstract: An apparatus for treating regurgitation of blood through a diseased heart valve having at least two leaflets includes a lollipop-shaped body member having a proximal end portion, a distal end portion, and an intermediate portion extending between the end portions. The intermediate portion includes an expandable occluding member having an adjustable diameter so that, during at least a portion of the cardiac cycle, at least one of the heart leaflet coapts with a portion of the occluding member to mitigate or prevent regurgitation of blood through the diseased heart valve. The proximal end portion is physically connected to the occluding member and includes a connecting mechanism for operably mating with an adjustment member for adjusting the position and diameter of the occluding member within the diseased heart valve. The distal end portion includes an anchoring member for securing the apparatus in a heart chamber containing the diseased heart valve.

    Abstract: A totally implantable method for occluding the urethra or bladder neck utilizing an occlusive cuff connected to a control mechanism via a conduit tube. The occlusive cuff is reversibly changed from an activated (occlusive condition) to a de-activated (non-occlusive) condition by depressing a deactivation button contained within a resilient, elastomeric sheath surrounding the control mechanism. The occlusive condition is once again obtained by depressing an activation button also situated within the resilient sheath. In the occlusive condition, a preset tension is applied to a flexible diaphragm through a tensioning suture by a constant force spring contained within the control mechanism. This tension is translated into an occlusive pressure applied to the urethra or bladder neck sufficient to prevent urinary leakage.

  • Patent number: 8801683
    Abstract: A bowel management system includes a waste collection catheter having at least two distinct sections. The first section is patient proximal when disposed in the patient's rectum and has durometer hardness in the range of about 50A to about 90A. The second catheter section is connected to the first section and has durometer hardness in the range of about 5A to about 49A. A selectively collapsible, substantially spherical retention balloon is attached coaxially and exterior of the first catheter section such that the proximal-most end of the retention balloon is coincident to the proximal-most end of the first section of the waste collection catheter, the substantially spherical retention balloon having an inflated size so as to be sufficiently large enough to retain the patient proximal end of the catheter in the patient's rectum without being so large as to trigger a defecatory response in the patient.

  • Publication number: 20140128666
    Abstract: An apparatus (60) for use within a woman's urethra (9) for inhibiting urine outflow when her intra-abdominal pressure rises. The apparatus (60) includes a generally tubular device (50) having a proximal end and a distal end and defining a longitudinal axis. Device (50) comprises structure (5) that is constructed and arranged to define a longitudinal passageway (14) that extends entirely through the device (50) from the proximal end to the distal end. Structure (5) is further constructed and arranged to be altered via an increase in intra-abdominal pressure, from a first state in which the passageway (14) is open along its length and able to conduct urine to a second state in which the passageway (14a) is more restricted or is closed off, to inhibit the passage of urine.

  • Patent number: 8690861
    Abstract: A device for the in situ clearing of blockages in a tube includes a controller and a clearing member. The controller can have a housing and an actuator for generating repetitive motion. The clearing member can be releasably coupled to the controller and suitable for insertion in the tube. The tube can be at least partially disposed within a living being. The controller can be located external to the living being. The clearing member can have a first end releasably coupled to the actuator, at least one flexible section which permits axial displacement of the clearing member, and a second end suitable for repetitively engaging and disrupting the blockage. The flexible section permits the clearing member to repetitively engage and disrupt the blockage within one of a straight and a curved portion of the artificial tube.

  • Publication number: 20140081075
    Abstract: A urinary control device for sealing off at a neck and along the inside wall of a bladder to prevent leaking and dislodging of the device from within the bladder is disclosed. The device includes an inner tubular member. The device also includes an expandable sealing member. A deployable stiffening member is positioned within the expandable sealing member. The stiffening member expands within the expandable sealing member to erect and shape the expandable sealing member. The deployable stiffening member strengthens the expandable sealing member, retaining the device within the bladder and sealing off the bladder against leaking.

  • Publication number: 20140073844
    Abstract: An incontinence treatment device includes a support, a pump, and anchors each attached to a connection line. The support includes an inflatable bladder and the pump is body-implantable and attachable to the inflatable bladder. The pump is configured to selectively inflate the inflatable bladder to compress the tissue of the urethra. The connection lines are attached to the support. A first anchor is fixed to the first connection line and a second anchor is coupled to the second connection line, where the second anchor is an adjustable anchor. The adjustable anchor is configured to be movable and position-adjustable relative to the second connection line.
