Publication number: 20230380820Abstract: Apparatus for sealing a vascular wall penetration disposed at the end of the tissue tract comprises a shaft, an occlusion element, a hemostatic implant, and a protective sleeve. The apparatus is deployed through the tissue tract with the occlusion element temporarily occluding the vascular wall penetration and inhibiting backbleeding therethrough. The hemostatic implant, which will typically be a biodegradable polymer such as collagen carrying an anti-proliferative agent or coagulation promoter, will then be deployed from the sealing apparatus and left in place to enhance closure of the vascular wall penetration with minimum scarring. The implant may be radiopaque to allow observation before release.Type: ApplicationFiled: August 3, 2023Publication date: November 30, 2023Applicant: Cardiva Medical, Inc.Inventors: Zia Yassinzadeh, Delfin Pelayo

Patent number: 7993366Abstract: The present invention advantageously provides self-tensioning occlusion devices, systems, and methods for percutaneous access and closure of vascular puncture sites. One device includes a catheter body, an occlusion member, and a tensioning member. The occlusion member, such an expansible member, is disposed on a distal end of the body. The tensioning member, such as a spring or coil, is slidably disposed over the body and proximal the expansion member. Generally, during application, the tensioning member will be deployed against subcutaneous tissue so as to apply tension to the expansible member against the puncture site. The substantial hold once the tension is applied is then provided by an external element, such as an anchoring clip.Type: GrantFiled: October 25, 2004Date of Patent: August 9, 2011Assignee: Cardiva Medical, Inc.Inventors: Zia Yassinzadeh, Delfin Pelayo
