Publication number: 20210275177Abstract: Devices and methods for deploying an anastomotic stent between portions of the gastro-intestinal (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.Type: ApplicationFiled: May 24, 2021Publication date: September 9, 2021Inventors: Kenneth F.

Publication number: 20120130417Abstract: A catheter for penetrating and dilating a passage from a first body lumen to a second body lumen comprises a catheter body, a tapered dilating tip at a distal end of the catheter body, a reciprocatable needle carried in a central passage of the catheter body, a deployable anchor carried near a distal end of the needle, and an advanceable blade carried in a slot at the distal end of the catheter body and advanceable in a track formed axially along the needle. The catheter can be used to penetrate adjacent luminal walls by first advancing the needle, and advancing the dilator over the needle followed by deploying the anchor, applying proximal tension to hold the adjacent tissue layers together, and then advancing the dilator with the exposed blade to fully dilate the passage.Type: ApplicationFiled: January 31, 2012Publication date: May 24, 2012Inventors: Keke Lepulu, Hoang Phan

Patent number: 7578828Abstract: Methods and devices for placing a conduit in fluid communication with a target vessel and a source of blood, such as the aorta or a heart chamber. The device may be actuated using one hand to place the conduit. The invention allows air in the conduit to be removed prior to placement of the conduit. The invention deploys the conduit in the target vessel by moving a sheath in a distal direction and then in a proximal direction. A conduit is provided with a reinforcing member to prevent kinking of the conduit, and a structure for preventing blockage of the conduit by tissue. A vessel coupling may be used to secure a conduit to a target vessel so as to preserve native blood flow through the vessel, and the conduit may be placed in fluid communication with a target vessel via a laparoscopic or endoscopic procedure.Type: GrantFiled: May 19, 2003Date of Patent: August 25, 2009Assignee: Medtronic, Inc.Inventors: Darin C.
