20090118748 | Impermanent biocompatible fastener - A biocompatible fastener particularly well-suited for use in fundoplication procedures. In a preferred embodiment, the fastener is designed to break within the span of approximately three to six months after implantation and comprises a male portion and a female portion. The male portion includes a first base member, the first base member being generally flat and oval. A pair of male members are mounted on the bottom surface of the first base member, each male member comprising a cylindrical post extending downwardly from the bottom surface of the first base member and a conical head disposed at the bottom end of the post. The female portion includes a second base member, the second base member being generally flat and oval. A pair of sleeves are mounted on the top surface of the second base member and extend upwardly therefrom. Each sleeve defines a bore adapted to receive a head from a corresponding male member and has an inner flange formed thereon. The flange extends radially into the bore and is engageable with the head once the head has been inserted therepast so as to inhibit withdrawal of the head from the bore. Except for an outer coating on each of the two heads, the fastener is made entirely of a non-bioabsorbable material or a bioabsorbable material having a relatively slow degradation rate. By contrast, the outer coating is made of a bioabsorbable material having a relatively fast degradation rate. The thickness of the outer coating is appropriately selected so that degradation of the outer coating permits each head to be withdrawn past its flange after a desired period of time. | 05-07-2009 |
20090177192 | METHOD FOR ABLATING TISSUE TO FACILITATE IMPLANTATION AND APPARATUS AND KIT FOR USE THEREWITH - A method for treating a mammalian body having tissue comprising creating a cavity in the tissue formed by an internal surface of the tissue. The internal surface is ablated. An implant-forming material is introduced into the cavity to create an implant in the tissue. The ablation of the internal surface inhibits migration of the implant. An apparatus and kit for use with the method are provided. | 07-09-2009 |
20100022985 | Vial adaptor - A vial adapter suitable for use in transferring fluid from a vial to a needleless syringe, the vial having a top end sealed with a septum. According to one embodiment, the vial adapter comprises (a) a body, the body having a top end, a bottom end and an inner cavity, the inner cavity being dimensioned to receive the vial, with the bottom end of the body extending below the bottom end of the vial; (b) a needle-bearing member mounted within the body, the needle-bearing member comprising a hollow needle extending downwardly into the inner cavity of the body for puncturing the septum of a vial disposed in the inner cavity; (c) a luer-lock-bearing member mounted on the top end of the body, the luer-lock-bearing member comprising a top portion and a bottom portion separated by a radial wall, the top portion being a female luer-lock, the bottom portion including a tubular structure in fluid communication with the hollow needle; and (d) a valve disposed within the luer-lock-bearing member for controlling fluid flow from the bottom portion to the top portion, the valve being opened by attachment of the needleless syringe to the vial adapter. | 01-28-2010 |
20110189240 | MICROENCAPSULATED COMPOSITIONS FOR ENDOLUMINAL TISSUE ENGINEERING - A tissue engineering composition adapted for application to an interior surface of a body lumen of a patient. The composition comprises (a) a carrier medium that is adapted to flow and to stably adhere the composition to the body lumen and (b) microcapsules, which are dispersed within the carrier medium and which contain one or more living cells encapsulated within a coating that includes a biodegradable polymer. The composition promotes growth of the cells on the lumen surface subsequent to application of the composition to the lumen. | 08-04-2011 |
20120150070 | OVERTUBES FOR EUS FNA DRAINAGE - A device for performing multiple medical procedures comprises a needle extending from a proximal end which remains external to a body during use to a sharpened distal end configured for insertion to a target site within a body via a body lumen. A sheath is slidably receivable over the needle, the sheath extending from a proximal end which remains external to the body during use to a distal end. A stent is slidably received over the sheath, the stent including an anchoring mechanism configured for anchoring in a desired position within the body lumen. | 06-14-2012 |
20120310154 | APPARATUS AND METHOD FOR TREATING TISSUE - An apparatus for treating tissue of a mammalian body. In one embodiment, a spring mechanism is carried by first and second tubular members and actuatable for moving a needle from a first position disposed within the distal extremity of the first tubular member to a second position extending distally of the first tubular member. In another embodiment, a nozzle is coupled to the distal extremity of an elongate tubular member for delivering a material into tissue of the mammalian body. In a further embodiment, a flexible elongate member provided with a recess is introduced into a cavity of the body to capture tissue in the recess and electrical energy is applied to such tissue in the recess so as to change the compliance of the tissue. | 12-06-2012 |
20130090653 | Method for Ablating Tissue to Facilitate Implantation and Apparatus and Kit for Use Therewith - A method for treating a mammalian body having tissue comprising creating a cavity in the tissue formed by an internal surface of the tissue. The internal surface is ablated. An implant-forming material is introduced into the cavity to create an implant in the tissue. The ablation of the internal surface inhibits migration of the implant. An apparatus and kit for use with the method are provided. | 04-11-2013 |
