Publication number: 20210361305Abstract: Embodiments disclosed herein relate to an aspiration catheter comprising a catheter body that can have a first end and a second end and an aspiration lumen extending through the catheter body. The aspiration lumen can have an aspiration opening located in a distal portion of the aspiration catheter. The catheter can have an assistive jet element extending through a wall of the aspiration lumen. The assistive jet element can have an assistive jet channel. The assistive jet element can be adaptable to draw blood through the assistive jet element from a location outside of the catheter body adjacent to the assistive jet element and into the aspiration lumen when suction is applied to the aspiration lumen and can be configured to break apart a thrombus or obstruction in the aspiration lumen.Type: ApplicationFiled: August 3, 2021Publication date: November 25, 2021Applicant: ASAHI INTECC CO., LTD.Inventors: Takeshi MOGI, Michael K. LUK, Satoshi NAMIMA

Patent number: 9757118Abstract: A method of placing a suture through tissue includes placing a band on a finger of a user, where the band is attached to a head of a suturing device, and employing the finger and the device in identifying an intracorporeal tissue landmark and placing the head of the suturing device at the intracorporeal tissue landmark. The method additionally includes engaging a throat of the head of the suturing device with the intracorporeal tissue landmark, and ejecting a needle out of a needle exit port and through the tissue. The needle exit port is located on a proximal portion of the head of the suturing device.Type: GrantFiled: September 30, 2014Date of Patent: September 12, 2017Assignee: Coloplast A/SInventors: Allen Gaynor, Michael K.

Patent number: 8915928Abstract: A suture fixation system includes a suture assembly having an anchor, an introducer, and a delivery device. The introducer is attachable to a finger of a person and includes a platform attached to an exterior of the introducer and a zip line attached to the platform. The delivery device is movable along the zip line and configured to removably retain the anchor. The introducer allows the finger to identify a target landmark within a patient and the delivery device is movable along the zip line and attachable to the platform to position the anchor for insertion to the target landmark.Type: GrantFiled: October 15, 2010Date of Patent: December 23, 2014Assignee: Coloplast A/SInventors: Allen Gaynor, Michael K.

Patent number: 8852212Abstract: A suturing assembly is provided that is configured to pull a capsule attached to a suture through tissue. The suturing assembly includes a shaft aligned on a longitudinal axis of the suturing assembly, and a head coupled to the shaft. The head includes a proximal portion and a distal end spaced apart from the proximal portion by a throat. The proximal portion houses a needle that is movable through a needle exit port. The proximal portion of the head and the needle exit port are both aligned on the longitudinal axis. A proximal side of the distal end of the head defines a cavity adapted to receive the capsule and a distal side of the distal end of the head defines a slot adapted to allow the suture to pass through the distal end of the head and into the cavity.Type: GrantFiled: June 24, 2013Date of Patent: October 7, 2014Assignee: Coloplast A/SInventors: Steven McClurg, Christopher Anthony Thierfelder, Allen Gaynor, Pornpimon Ongmorakot, Timothy Andrew Bachman, Christian Richard Trifilio, Matthew Vail Leyden, Nicholas Ellering, Michael K.
