  • Patent number: 10258343
    Abstract: A left atrial appendage occluder comprises an elastic closure disc, and a supporting structure connecting with the closure disc and being located on one side of the closure disc, with the supporting structure comprising a central end connecting with the closure disc and a plurality of interconnected and bent struts, wherein at least one anchoring thorn is set near the end of at least one strut with the anchoring thorn toward the closure disc. The left atrial appendage occluder has a stable structure, a good positioning and sealing effect on the cavity wall in the left atrial appendage, and it is easy to position repeatedly; it can also be recycled before separating from a conveyor. When in surgical operation, the left atrial appendage occluder can select the position area based on the actual shape and size of the patient's left atrial appendage, so the surgical risk is lowered.

  • Patent number: 8979821
    Abstract: A biomaterial mass is inserted through a punctum into a canaliculus in the lacrimal outflow system with a syringe. The mass has an outer cross section that is less than the inner cross section of the canaliculus. The mass absorbs liquid to swell to form a lacrimal filler or sealing mechanism. The lacrimal filler has an external cross section that conforms to the internal cross section of the canaliculus and a soft outer surface relative to the surrounding tissues to prevent erosion of the canaliculus lining. The lacrimal filler forms an occlusion that prevents the outflow of liquid through the lacrimal outflow system to retain tears within the eye to maintain eye lubrication and wetness. The mass and syringe are provided in kit with a rubber stopper and, optionally, a punctal dilator, an injecting catheter, and an enzyme for dissolving or degrading the lacrimal filler at a later time.

    Abstract: The HemZem Anal Pile Driver Medical Device is a nonabsorbable medical minipad made from 16 ply layered facial tissue paper. The minipad is novel in that it is employed as an anal pessary using the body's own distinct anatomy, physiology, and chemistry to remain in place, and prevent the prolapse of anatomical hemorrhoids. When inserted into the anal canal, the HemZem Anal Pile Driver prevents medical complications such as itching, burning, or pain associated with, or secondary to prolapsing hemorrhoids. The HemZem Anal Pile Driver also serves as an absorbent minipad for anal mucus, and prevents soiling of clothing from such mucus, or topical ointments, creams, and gels commonly used to treat hemorrhoids. The US Food and Drug Administration classified the HemZem Anal Pile Driver as a Class I medical device on Aug. 23, 2012.

The body portion is defined by an open distal end, an open proximal end and a wall portion. The wall portion further includes at least one window extending therethrough. The retaining flange is configured to have an outer periphery that is larger than the outer periphery of the body portion. A method of delivering a therapeutic agent to a patient using a punctal plug is also disclosed.

  • Patent number: 8235048
    Abstract: A device for occluding the fallopian tube having a wire composed of a shape memory material and an outer material encapsulating at least a portion of the wire. The device has a first elongated configuration for delivery and a second configuration for placement. In the second configuration, the wire moves toward its shape memory position and has a U-shape defined by a curved portion and first and second leg portions extending from the curved portion, the first and second leg portions extending downwardly from the curved portion and laterally outwardly.

  • Patent number: 8201562
    Abstract: A multi-piece punctal plug has one or more superficial plugs connected to an anchor plug deeper in the naso-lacrimal canaliculus. The anchor is fixed to the wall of the lacrimal duct while the superficial plugs are axially and detachably secured to the anchor plug so that the multi-plug complex may be inserted or removed together as one, or the superficial plugs may be detached separately and replaced securely without disturbing the anchor. Removal and insertion is accomplished by a specific tool having an end for engaging the plugs.

  • Patent number: 8192389
    Abstract: Monocanaliculonasal and/or monocanalicular intubation assembly mainly intended for nasolachrymal imperforation, comprising a mandrel (2) made of a first substantially rigid material, such as a metal, and a tube (1) made of a second material that is less rigid than the first material and essentially flexible, such as silicone, a blocking plug (6) for locking the tube in position in the lachrymal duct and protruding laterally from the tube, characterized in that the length of the tube (1) is smaller than the length of the mandrel (2) and the mandrel (2) has a greater thickness, measured in a direction perpendicular to the longitudinal direction, relative to that of the tube (1), such that said mandrel can be inserted inside the tube and withdrawn therefrom.

  • Publication number: 20120055491
    Abstract: The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization s effected by passing a current through there resilisent structure to the tubal walls.
