Publication number: 20230414916Abstract: An introducer for insertion of a medical device into a patient's vasculature includes an elongate introducer body, a hub, and a hemostatic valve. The elongate introducer body includes a longitudinal axis, a proximal region, a distal region, and an inner lumen. The hub is coupled to the proximal region of the introducer body. The hemostatic valve is disposed within the hub and forms a liquid-tight seal across the inner lumen. The introducer includes a guide configured to guide an object towards the center of the valve during insertion of the object.Type: ApplicationFiled: June 26, 2023Publication date: December 28, 2023Applicant: ABIOMED, Inc.Inventors: Glen R.

Publication number: 20220126080Abstract: A system for providing vascular access in a patient's body may comprise at least one hemostatic valve and at least one clamp to be used with a vascular graft. The vascular graft comprises a tubular body having a proximal end and a distal end, the proximal end being configured to be attached to a vessel in a patient's body. The at least one valve is configured to be attached to the distal end of the graft's tubular body and comprises a housing including a flexible membrane that allows a medical device to be inserted through the membrane into said vascular graft. The valve further comprises an introducer sheath configured to be inserted into the distal end of the graft's tubular body.Type: ApplicationFiled: October 21, 2021Publication date: April 28, 2022Applicant: ABIOMED EUROPE GMBHInventors: Glen Fantuzzi, Dion Mraz, Daniel Raess, David Brousseau, Susanna Mayo

Patent number: 11179556Abstract: A system for providing vascular access in a patient's body may comprise at least one hemostatic valve (610) and at least one clamp (210) to be used with a vascular graft (110). The vascular graft (110) comprises a tubular body having a proximal end (110A) and a distal end (110B), the proximal end (110A) being configured to be attached to a vessel in a patient's body. The at least one valve (610) is configured to be attached to the distal end (110B) of the graft's tubular body and comprises a housing (616) including a flexible membrane (611) that allows a medical device (810) to be inserted through the membrane (611) into said vascular graft (110). The valve (610) further comprises an introducer sheath (615) configured to be inserted into the distal end (110B) of the graft's tubular body.Type: GrantFiled: October 2, 2015Date of Patent: November 23, 2021Assignee: ABIOMED EUROPE GMBHInventors: Glen Fantuzzi, Dion Mraz, Daniel A.

Publication number: 20210145475Abstract: A cannula supporting a percutaneous pump can include a proximal section with a first flexural modulus. The cannula can include one or more distal sections with a flexural modulus that is different than the first flexural modulus. The material and its arrangement along the length of the cannula can be selected so as to influence bending properties. This can, for example, allow efficient positioning of the cannula in a desired location without displacing the guidewire.Type: ApplicationFiled: October 26, 2020Publication date: May 20, 2021Inventors: Zhenghong Tao, Christopher Zarins, Dion Mraz, Stephen Vaughan, Julius Steven Becker
