Patent number: 11833314Abstract: A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.Type: GrantFiled: June 18, 2021Date of Patent: December 5, 2023Assignee: ABIOMED, INC.Inventors: Scott C. Corbett, Glen R. Fantuzzi, John Murphy, Frank Kirchhoff, David Brousseau, Thorsten Siess

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.
