  • Patent number: 7875042
    Abstract: A suture anchor loader comprises a housing with a port. A channel extends into the housing from the port, the channel being dimensioned to receive a surgical needle. A suture anchor is preloaded in the channel with a length of suture connected to the suture anchor and stored in the housing. A push rod is slideably positioned in the channel such that the suture anchor is intermediate the push rod and the port. An actuator is operatively connected to push rod to selectively deploy the anchor into the needle.

  • Patent number: 7753936
    Abstract: A fastening device for clamping and fastening tissue together with fasteners formed from an adhesive is disclosed. An embodiment of the adhesive fastening device can clamp a first and a second portion of tissue together between a first and a second jaw, and can place a fluid polymer adhesive into tissue and form it into a polymerized surgical fastener within the tissue. The adhesive fastener can be formed as a polymerized shank or shaft extending through the tissue, and can have one or more heads formed on the shank. The shank can be formed solely from the polymerizable adhesive, or can be formed from another material such as nitinol, titanium, stainless steel, suture, or a plastic. Shanks of other material can be combined with the adhesive. Alternately, an adhesive fastener can be formed extending distally from a distal end of the surgical device. And, an adhesive fastener can be formed around a luminal tissue or within luminal tissue.

  • Patent number: 7740646
    Abstract: A design for a suture for use in suture appositioning techniques, and a method for use are disclosed. In one embodiment the suture may comprise a hollow length having a wall forming a lumen, which may serve as a conduit through which fluid may be pumped and discharged through a plurality of perforations in the wall. In another embodiment the suture may comprise a plurality of suture members connected by a connecting member. In one embodiment of a method disclosed, a suture having a hollow length having a wall forming a lumen, with a plurality of perforations in the wall, may be placed in a stitching procedure to apposition tissues, and a fluid such as an adhesive, adhesive activating agent or drug may be pumped through the lumen and discharged out the perforations for various beneficial effects.

  • Publication number: 20100130941
    Abstract: 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.

  • Patent number: 7708180
    Abstract: A material comprising a matrix or a buttress is impregnated with an adhesive initiator and is used with a surgical stapling device and an adhesive. The tissue and material are stapled together, and a knife in the surgical stapling device cuts the tissue and the material. The adhesive is applied across the cut and sets up or polymerizes to seals the cut when the adhesive contacts the adhesive initiator. The surgical stapling device can place the staples in a linear, arcuate, or circular array, and can anastomose luminal tissue. The methods of use can include stapling luminal tissue end to end, stapling two portions of material onto ether side of tissue, and stapling two portions of tissue onto a portion of material. Additionally, a portion of adhesive filed material can be stapled onto one side of portion of tissue and the adhesive initiator impregnated material can be stapled onto the other.

  • Patent number: 7561916
    Abstract: 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.

  • Publication number: 20080114315
    Abstract: A multiple use fluid dispenser dispenses a flowable material in a precise pattern and quantity with leaking and clogging between dispensing avoided by employing a trigger fired syringe plunger to expel a fixed volume through a band. Between strokes, an advancement knob rotates the band over a distal dispensing tip to a nondispensing location that wipes excess flowable material and seals a dispensing orifice in a fluid conduit. The advancement knob further may rotate the band to a dispensing position wherein a combination of one or more dispensing holes produce a desired pattern and rate of flow with material over the dispensing hole(s) serving to initiate the flowable material, to control placement, serve as a detachable bandage or buttress material, etc.

  • Publication number: 20080109034
    Abstract: A surgical implant for adhering two portions of tissue together with a polymer adhesive is disclosed. The surgical implant has a matrix structure with one or more layers and a plurality of holes for tissue growth therethrough. The matrix structure controls placement of the adhesive to minimize adhesive area and maximize tissue regrowth areas. In addition, the surgical implant can include drugs and adhesive initiators, and can include multiple layers of structure with any combination of holes, drugs, adhesives and adhesive initiators within. Additionally, the surgical implant can be surrounded by a rapidly dissolving pouch to prevent unwanted polymerization of the adhesive prior to placement in the body.

  • Patent number: 6139489
    Abstract: A surgical device for use with a video display and for retracting, viewing, and accessing tissue is described. The surgical device comprises an elongated platform and a concave head connected to a distal end of the platform. The concave head defines a cavity that provides a working space for an end-effector of an instrument. The surgical device further comprises an image sensor attached to the inside of the concave head so that tissue within the working space may be imaged by the image sensor to provide an electrical signal for a video display. The surgical device further comprises an illumination means for illuminating tissue within and adjacent to the cavity of the concave head. A power source is provided for powering the image sensor and the illumination means. A handle is attached to the proximal end of the platform.
