Patent number: 11197952Abstract: A vascular access port can include a base that can be attached to a vessel and a body extending away from the base in at least a vertical direction. A height of the body in the vertical direction can be sufficiently small such that the entire port can be implanted subcutaneously in a patient. The port can include a guidance passageway that is at least partially defined by the body and can direct an access device into a vessel of a patient when the port is attached to the vessel. In some arrangements, the guidance passageway includes a funnel region that decreases in size from a proximal end of the guidance passageway toward a distal end of the guidance passageway that defines an opening through the bottom surface of the port.Type: GrantFiled: April 19, 2019Date of Patent: December 14, 2021Assignee: Advent Access Pte. Ltd.Inventors: Nathaniel P. Young, Mark A. Crawford

Patent number: 11134950Abstract: A method of attaching an implant to a vessel can include clamping a portion of a wall of a vessel within a patient. The method can also include positioning an implant adjacent to an outer surface of the wall of the vessel, and the implant can include an access port. The method can also include cutting the wall of the vessel about the portion of the wall that has been clamped, passing the portion of the wall that has been clamped and that has been cut about through the implant to remove the portion of the wall from the patient and to provide an opening in the vessel, and securing the implant to the vessel such that the access port is in direct fluid communication with an interior of the vessel via the opening in the vessel.Type: GrantFiled: March 13, 2019Date of Patent: October 5, 2021Assignee: Advent Access Pte. Ltd.Inventors: Duane D. Blatter, Trent J. Perry, Nathaniel P. Young, Jeffrey E. Ransden

Patent number: 10894120Abstract: In certain systems disclosed herein, one or more of a first vascular access port and a second vascular access port can be selected by a customer. Each of the first and second vascular access ports can be implanted subcutaneously within a patient, and each can include a base configured to be attached to a vessel, a body that extends away from the base, and a guidance passageway that extends through the body and the base and includes a funnel region. A maximum height defined by the base and body of the second vascular access port can be greater than a maximum height defined by the base and body of the first vascular access port.Type: GrantFiled: March 11, 2019Date of Patent: January 19, 2021Assignee: Advent Access Pte. Ltd.Inventors: Nathaniel P. Young, G. Doug Smith, Mark A. Crawford

Patent number: 10773010Abstract: Ports for accessing a vessels within a patient include passageways that can guide needles or other access devices directly into the vessels. The ports can be implanted subcutaneously within a patient. Some ports may be used in the creation and use of vascular access buttonholes.Type: GrantFiled: March 16, 2018Date of Patent: September 15, 2020Assignee: Advent Access Pte. Ltd.Inventors: Christopher M. Phillips, Nathaniel P. Young, Trent J. Perry, Duane D. Blatter, Mark A. Crawford, G. Doug Smith, Steven Johnson

Publication number: 20190167917Abstract: Systems, apparatuses and methods for stabilizing an implant used in a medical procedure, for example, an implant used to facilitate repeated needling in kidney dialysis. The apparatus may include an implant holder including at least one implant-engaging surface configured to cause compression of skin adjacent the implant. The apparatus may also include a holding mechanism coupled to the implant holder and configured to engage patient anatomy in order to secure the implant holder in place above the implant. In certain implementations, the implant holder may be coupled to an adhesive patch or may be flexible and configured to at least partially conform to the patient anatomy when a strap assembly is tightened around patient anatomy.Type: ApplicationFiled: November 28, 2018Publication date: June 6, 2019Applicant: Advent Access Pte.
