Patent number: 11185321Abstract: Suture clip deployment devices for applying suture clips to sutures are described. Some embodiments can include a generally tubular main body and a vacuum port located at the distal end, a hollow inner body longitudinally slidable within the main body and extending from the main body at its distal end, and a suture recess located in the generally tubular main body. At least one suture clip configured to frictionally fit on an outer surface of the inner body is deployed during use. Clip deployment can occur after a vacuum source is applied to the device so as to draw the suture into the device. The suture lines can be retrieved through the suture recess, and the device can be actuated so as to deliver the suture clip off the delivery device and onto the suture, locking the suture in place.Type: GrantFiled: June 10, 2019Date of Patent: November 30, 2021Assignee: Edwards Lifesciences CorporationInventors: Travis Zenyo Oba, Michael C. Murad, Manouchehr A. Miraki, Anthony P. Carcia, Fabian Daniel Schroeder, Raffaele Mazzei, Tyler Douglas Smith

Patent number: 11178861Abstract: A tool for feeding a fishing line through the eyelets of a fishing rod has a loop of filament attached to an elongated guide and twisted across itself at a distal overlap to form a figure-eight with proximal and distal portions wider and narrower, respectively, than the eyelets. The wider portion facilitates insertion of a free end of the line into the loop. The loop is resiliently flexible so that the overlap separates and then recovers as the inserted line is passed transversely through the gap into the narrower portion of the figure-eight. The passed line is then transversely wedged in the narrower portion of the figure-eight. The loop is also resiliently flexible so that, as the guide leads the loop and the line through each eyelet, the wider portion of the loop compresses and then expands, inhibiting inadvertent withdrawal of the tool from an eyelet.Type: GrantFiled: June 6, 2017Date of Patent: November 23, 2021Inventors: John L. Wilcoxon, Brandon K. Lattimer

Patent number: 11160547Abstract: Suturing techniques and sutures capable of reducing the incidence of incisional herniae, including but not limited to subcutaneous surgical sutures performed after laparotomy. Such a suture includes a circular suture having at least first portions that are within a first region of tissue of a suture area that further contains rows of puncture sites aligned approximately parallel to an incision on opposite sides of the incision. The first region of tissue is located between the rows of puncture sites and surrounds the incision, and the first portions of the circular suture extend along the rows of puncture sites. The suture further includes a continuous suture in the suture area that penetrates the puncture sites and traverses the incision. The circular suture disperses stresses induced by tension in the continuous suture to inhibit tearing of tissue at the puncture sites.Type: GrantFiled: March 29, 2018Date of Patent: November 2, 2021Inventor: Resit Demir

Patent number: 11129609Abstract: A suture passer includes a handle assembly, a shaft extending distally from the handle assembly, an end effector assembly coupled to a distal end portion of the shaft, and an overstroke assembly. The overstroke assembly effects an opening and a closing of the end effector assembly while also preventing an overstroke of the handle assembly from damaging components of the suture passer.Type: GrantFiled: January 30, 2019Date of Patent: September 28, 2021Assignee: Covidien LPInventors: Matthew A. Dinino, Jacob C. Baril, Kevin Desjardin, Eric Brown

Patent number: 11116497Abstract: A suture-securing device includes a first tubular element, shaped to define a first lumen therethrough, and having first and second ends; and a second tubular element, shaped to define a second lumen therethrough, and having first and second ends. The suture-securing device is configured to have (a) an unlocked configuration in which the first end of the second tubular element is disposed closer to the first end of first tubular element than is the second end of the second tubular element, and the sutures are disposable within and slidable through the first and second lumens, and (b) a locking configuration in which the second end of the second tubular element is disposed closer to the first end of first tubular element than is the first end of the second tubular element, and the sutures are inhibited from sliding through the first and second lumens. Other embodiments are also described.Type: GrantFiled: January 8, 2019Date of Patent: September 14, 2021Assignee: 4Tech Inc.Inventors: Francesco Maisano, Hugo Vanermen, Ottavio Alfieri, Idan Tobis, Andrea Guidotti, Paolo Denti

Patent number: 11096731Abstract: A reduction and fixation tool has two principle component parts—an intra-articular spoon with a blade, and a handle that docks with the spoon. The spoon has a proximal hub onto which the handle docks. In one example of the tool as it would be used with a fractured scaphoid, the spoon has a distal blade, curved and narrow to slip beneath the undersurface of the scaphoid and to lift the distal fragment of the bone back into proper alignment (fracture reduction). The handle, docked to the spoon, serves as a lever to easily accomplish the reduction, and as a guide for the central insertion of a guide wire into the scaphoid across the fracture site.Type: GrantFiled: October 3, 2018Date of Patent: August 24, 2021Inventors: Jaiyoung Ryu, Terry L. Whipple

Patent number: 11083460Abstract: A method of percutaneously creating a fistula includes inserting percutaneously a medical instrument to a target location having a first blood vessel and a second blood vessel. A fastener is then deployed via the medical instrument to the target location. The fastener is in a first configuration before the deploying and a second configuration after the deploying. The fastener limits relative movement between the first blood vessel and the second blood vessel when in the second configuration. An anastomosis between the first blood vessel and the second blood vessel is percutaneously produced.Type: GrantFiled: August 2, 2019Date of Patent: August 10, 2021Assignee: Avenu Medical, Inc.Inventors: Mark A.
