| 20080269715 | Use of an Adhesive as an Intestinal Barrier for Bariatrics - An apparatus for achieving weight loss in a patient is disclosed. The apparatus has a barrier material and an applicator for dispensing the barrier material about the intestine. An injector is used to place the barrier material to block nutrient transfer from the intestine into the blood stream. The barrier material is a polymerizable adhesive that can be injected interstitially between layers of the intestine, or injected into vascular structures to partially block the flow of blood to the nutrient absorbing layers. | 10-30-2008 |
| 20090120994 | Surgical Fastening Device With Initiator Impregnation of a Matrix or Buttress to Improve Adhesive Application - 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. Cutting the material and tissue provides a path for the adhesive across the cut, and catalyzes the adhesive from contact with the adhesive initiator. | 05-14-2009 |
| 20090143818 | Use of an Adhesive to Treat Intraluminal Bleeding - A surgical device to stanch the flow of blood is disclosed. The surgical device can place an implantable adhesive over or around varices or other bleeders. The surgical device has a vacuum system for capturing tissue and an adhesive system to apply adhesive to the captured tissue. A vacuum chamber is used to contact tissue and contains a chamber therein for the reception of tissue. An adhesive applicator is provided within the vacuum chamber and moves longitudinally therein to apply adhesive to tissue. The surgical device can apply an adhesive patch to tissue or inject adhesive into tissue. Alternately, an adhesive actuator and a chemical agent can be dispensed to tissue within the vacuum chamber. | 06-04-2009 |
| 20090182195 | ENDOSCOPIC GUIDE SYSTEM - Various devices for use in endoscopic surgery and methods for manufacturing the same are provided. In one embodiment, an endoscopic guide device is provided and includes an injection molded rail and a c-shaped channel defining a track extending through the rail. The channel includes a plurality of slots formed in the c-shaped channel during the injection molding process. A plurality of wings can extend from opposed sides of the c-shaped channel. | 07-16-2009 |
| 20100023044 | ULTRASONIC SURGICAL SHEARS AND TISSUE PAD FOR SAME - An ultrasonic-surgical-shears tissue pad has a tissue-pad body including a base material and at least one filler material. An alternate ultrasonic-surgical-shears tissue pad has a tissue-pad body having adjoining first and second regions, wherein the first region includes a first material and wherein the second region includes a second material. An ultrasonic surgical shears includes an ultrasonic surgical blade and a clamping arm which is operable to open and close toward the blade and which has a transversely and resiliently flexible distal tip. An alternate ultrasonic surgical shears includes an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a tissue pad attached to the clamping arm and having a clamping surface, wherein at least a portion of the tissue pad is resiliently flexible in a direction substantially perpendicular to the clamping surface. | 01-28-2010 |
| 20100222713 | TISSUE PAD FOR USE WITH AN ULTRASONIC SURGICAL INSTRUMENT - An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. An elongated portion of the instrument can be configured for endoscopic applications and has an outside diameter of less than 6 mm. The construction includes a clamping mechanism, including a clamp arm pivotally mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces, exceeding 4 pounds when the trigger is fully closed. The clamping mechanism includes a two-piece pad design and pad material that enables the higher tissue clamping forces and a force-limiting mechanism that effectively smooths out abusive tissue forces. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural swing of the surgeon's thumb, whether gripping the surgical instrument right-handed or left handed. | 09-02-2010 |
| 20110251612 | ELECTROSURGICAL CUTTING AND SEALING INSTRUMENTS WITH CAM-ACTUATED JAWS - Various embodiments are directed to a surgical instrument comprising, a shaft, and an end effector. The shaft may be coupled to the handle and may extend distally along a longitudinal axis. The end effector may be positioned at a distal end of the shaft and may comprise first and second jaw members and a reciprocating member. The first and second jaw members may define first and second longitudinal slots. One or both of the jaw members may be pivotable relative to the other about a pivot point. The reciprocating member may be translatable distally and proximally parallel to the longitudinal axis and through the first and second longitudinal slots. A distal portion of the reciprocating member may define a blade. The instrument may comprise an overtube translatable distally to exert a force on a portions of the first and second jaw members tending to close the first and second jaw members. | 10-13-2011 |
| 20110282339 | SURGICAL INSTRUMENTS AND END EFFECTORS THEREFOR - Various forms of surgical instruments are disclosed. In various embodiments, an end effector having operable and closable jaws is attached to a distal end of an elongate shaft such that portions of the jaws are axially offset from the elongate shaft. Other jaw embodiments are coupled to an actuation arrangement that permits portions of the jaws to be moved out of axial alignment with the elongate shaft. Other jaw embodiments are configured to facilitate tissue dissection. Electrosurgical instruments are also disclosed. One embodiment employs a flexible electrode that is conformable to tissue. | 11-17-2011 |
