  • Publication number: 20080114381
    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.

  • Publication number: 20080112751
    Abstract: A multiple use adhesive dispenser facilitates precise, extended dispensing for a surgical procedure by sequentially positioning an ampoule containing a flowable material, such as a polymerizable monomer compound such as a cyanoacrylate adhesive. In one version particularly suited to an open surgical procedure, the ampoules are affixed to a tape substrate that is unreeled from an internal storage reel and transported proximate to an ampoule gripping mechanism with an underlying tape substrate peeled away and internally stored as each ampoule is positioned for dispensing. Actuating an ampoule advancement handle positions the next ampoule and squeezing a movable handle toward a fixed handle effects dispensing. Another version has an elongate shaft that internally augers each ampoule in succession into a pair of spaced jaws that are pinched together by actuating rods to dispense adhesive.

  • Publication number: 20030133075
    Abstract: A method for optimizing a prescription for laser-ablation corneal treatment or ophthalmic implant includes the steps of receiving a measured correction prescription for a current patient having a classification element associated therewith, the prescription having been measured using wavefront determination. A database of treatment outcomes on a plurality of previously treated patients is accessed, each treated patient outcome having associated therewith at least one classification element and comprising a preoperative wavefront-determined correction prescription and a postoperative visual profile. From the treatment outcomes in the database is calculated an average difference between the preoperative prescription and the postoperative profile for at least some of the previously treated patients having a classification element in common with the current patient.

  • Patent number: 4969498
    Abstract: A portable tire bead breaker utilizes a common jacking apparatus to lever a curved foot member against the bead portion of a tire/rim combination. A top stabilizer keeps the curved foot member in the proper orientation and a bead engaging foot member permits the breaking of difficult to break bead on tires having soft and limber sidewalls.
