Patent number: 11523830Abstract: Embolic coil implant systems and methods whereby coils are mechanically detachable are disclosed. The coils include a retention element that may be releasably retained within the distal end of an implant tool. The implant tool may include a fulcrum configured to engage a first filament and prevent the release of the coil when the first filament is engaged. Alternatively, an urging means and aperture may be disposed within the sidewall of the implant tool, and a first filament may, in conjunction with the aperture and sidewall, releasably retain the coil until the first filament is withdrawn. The implant tool may also include an alignment member for aligning the first filament.Type: GrantFiled: August 6, 2019Date of Patent: December 13, 2022Assignee: Penumbra, Inc.Inventors: Ben Tompkins, Arani Bose, Delilah Hui, David Barry, Stephen Pons, Aleksander Leynov

Patent number: 11399845Abstract: A vascular cage comprises a self-expandable frame including a plurality of elongated flexible bands. The frame is configured to transition between a compressed configuration and an expanded configuration. The expanded frame may form a three-dimensional cage configured to surround an interior volume as the frame is deployed. At least some of the plurality of bands may have a substantially rectangular cross-section.Type: GrantFiled: December 10, 2018Date of Patent: August 2, 2022Assignee: Penumbra, Inc.Inventors: Delilah Hui, Edsel San Diego, Ben Tompkins

Publication number: 20220087687Abstract: Soft embolic implants exhibiting secondary shapes are disclosed. Some of the embolic implants exhibit progressively increasing softness from the distal end to the proximal end of the coil. The embolic implants have a primary coil, an optional second coil, a shape wire, and a stretch resistant fiber disposed in the lumen of the primary coil. An optional distal support wire is also disclosed. The embolic implants include a proximal constraint assembly configured to be releaseably retained by a delivery device. Disposed near each end of some of the implants are elliptical hole washers through which the shape wire and the stretch resistant fiber are threaded. The embolic implants have a primary, linear configuration for delivery through an implant tool, and a secondary configuration after deployment from the implant tool. The secondary shape can be J-shaped, helical, spherical, complex, or a combination of shapes.Type: ApplicationFiled: December 6, 2021Publication date: March 24, 2022Inventors: Alexander Plagge Rabkin, Stephen Pons, Delilah Hui

Patent number: 10548606Abstract: Vessel occlusion coils disclosed that have a primary configuration for delivery and a secondary configuration for deployment that is conferred upon the devices by a stretch resistant member. In the secondary configuration, the stretch resistant member forms a stiffer coil and may have a greater diameter, and a more complex shape having some interior space, at one end than at the other end, for improved anchoring of the device in the vessel. The methods include intravascular delivery and deployment for implanting one or more vessel occlusion devices.Type: GrantFiled: January 14, 2014Date of Patent: February 4, 2020Assignee: Penumbra, Inc.Inventors: Delilah Hui, Ben Tompkins

Publication number: 20170172581Abstract: An aneurysm occlusion system includes a device positionable within a cerebral blood vessel covering a neck of an aneurysm on the blood vessel. The device includes an expandable tubular element having a lumen surrounded by a sidewall including a plurality of gaps. When expanded, the tubular element includes longitudinal standards arrayed helically in a proximal to distal direction. The standards support struts and the gaps are defined between adjacent struts and are sufficiently large to permit delivery of embolic coils or other embolic materials therethrough.Type: ApplicationFiled: March 6, 2017Publication date: June 22, 2017Applicant: Penumbra, Inc.Inventors: Arani Bose, Vikas Gupta, Dave Barry, Delilah Hui, Stephen Pons, Aleksandr Leynov
