  • Patent number: 10076330
    Abstract: Tissue anchors comprise a woven filament braid body having an elongated tubular configuration and a foreshortened configuration where proximal and distal ends of the body expand radially into double-walled flange structures while leaving a cylindrical saddle region therebetween. The tissue anchors are deployed through penetrations between adjacent tissue layers, where the flanges engage the outer surfaces of the tissue layers and the saddle region resides within the tissue penetrations.

  • Patent number: 10052106
    Abstract: Devices and methods for deploying an anastomotic stent between portions of the gastrointestinal (GI) tract are disclosed. The anastomotic stents are configured to atraumatically engage the tissue walls and to permit the flow of fluid, partially digested food, and food. The stents can be deployed using endoscopic catheter devices, laparoscopic tools, and combinations of both endoscopic tools and laparoscopic tools. Examples of anastomoses include anastomoses between the stomach and a portion of the intestines such as the jejunum. Anastomoses can also be formed between two closed ends of the intestines, such as two closed ends of the colon formed during a colon resection procedure. Anastomoses can also be formed between a fundal pouch formed during a gastric bypass procedure and the jejunum. Laparoscopic tools are disclosed to deploy a stent by selectively removing a radial restraint on a self expanding stent with the restraint removed through the laparoscopic access points.

  • Patent number: 9364259
    Abstract: A trocar has an elongate body and a tissue-penetrating tip. One or more radially extending blade(s) are provided near the tissue-penetrating tip of the trocar body so that they automatically open as the trocar is advanced through tissue. The blades will enlarge the penetration which was formed by the tip of the trocar.

  • Patent number: 8784437
    Abstract: The present invention relates to a tissue securement system, device and method for endoscopy or endosonography-guided transluminal interventions whereby a ligation or anchor is placed and secured into soft tissue. An objective of this invention is to provide a method to reduce gastroesophageal reflux by endosonography-guided intervention. Specifically, endosonography is used to insert a ligation element through the esophageal wall, through the diaphragmatic crus and into the fundus of the stomach. This ligation element placed from the esophagus and around the Angle of His to create a barrier to gastroesophageal reflux.

  • Patent number: 8777967
    Abstract: The present invention relates to a tissue securement system, device and method for endoscopy or endosonography-guided transluminal interventions through which a ligation is placed and secured into tissue. An objective of this invention is to provide a stable securement platform for the coupling of secondary anchors to the gastrointestinal tract. Specifically, endoscopy is used to insert an anchoring element through the walls of adjacent body cavities. The ends of the anchoring element are coupled together to form a loop. This anchoring element can be used to secure other anchors or devices to the gastrointestinal tract.

  • Patent number: 8425539
    Abstract: A device is provided for endoscopy or endosonography- guided transluminal interventions whereby two luminal structures in the body may be drawn toward each other and a fluid conduit formed in between. The device may have a penetrating member and a hollow central member to which is coupled a distal retention member and in one embodiment a proximal retention member. The retention members may each be positioned inside one of the luminal structures and expanded from a first condition to an expanded second condition having an increased radius. The length of the central member may be shortened and its diameter expanded to approximate the two retention members and thereby the luminal structures.

  • Patent number: 8357193
    Abstract: Transluminal access system includes a stent delivery catheter having a handle control mechanism. The catheter comprises a number of components for establishing an initial penetration between adjacent body lumens and subsequently implanting a stent or other luminal anchor therebetween. Manipulation of the stent components is achieved using control mechanisms on the handle while the handle is attached to an endoscope which provides access to a first body lumen.

  • Publication number: 20120071904
    Abstract: The present invention relates generally to medical methods and systems used to restore the angle of His and treat hiatal hernias and other conditions of the lower esophagus. More particularly, the present invention relates to a method and system that allows fixation of the distal esophagus and fundus of the stomach directly to the diaphragmatic crus muscle. The present invention provides a method where the diaphragmatic crus muscle is identified and precisely located from within and through the gastrointestinal lumen followed by the placement of a translumenal anchor which connects and secures the esophagus and stomach to the diaphragmatic crus muscle. This procedure reduces the hiatal hernia, restores the normal anatomy and treats conditions associated with the lower esophagus.

  • Publication number: 20100268029
    Abstract: A guidewire has a guidewire body with a distal end and a proximal end. A balloon or other tissue anchor is disposed at or near the distal end of the guidewire, and the guidewire may be used to draw two layers of tissue into apposition by placing the guidewire through a tissue penetration, deploying the tissue anchor, and drawing proximally on the guidewire body. Optionally, the guidewire may include deployable blades for enlarging a tissue penetration as the guidewire is advanced therethrough.

  • Publication number: 20090281379
    Abstract: A translumenal access system includes a translumenal access catheter, a trocar, and one or more guidewires. The trocar may be introduced through adjacent tissue layers, typically from an endoscope, and the translumenal access catheter introduced through the resulting penetration over the trocar. A balloon on the catheter may be used to dilate the penetration, and an enlarged distal portion of the balloon may be used to draw the tissue layers into apposition. The first stent may be exchanged for the trocar and a second stent may be introduced through a side port on the access catheter. The stents may be then used to introduced catheters or other interventional tools, optionally for delivering one or more stents to the enlarged tissue penetration.
