Patent number: 10500044Abstract: A delivery system and method for delivering a prosthetic heart valve to the aortic valve. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic valve through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.Type: GrantFiled: July 27, 2017Date of Patent: December 10, 2019Assignee: Edwards Lifesciences CorporationInventors: Teodoro S.

Patent number: 10449346Abstract: An improved tattooing needle assembly and support assembly for the needle assembly are provided. The needle assembly includes a needle component extending through a main case into an aperture assembly. The needle component is configured to reciprocate between a stowed configuration, in which a tip of the needle component is positioned within the aperture assembly, and a deployed configuration, in which the tip extends beyond the aperture assembly. A tattooing machine causes the needle component to move to the deployed configuration while opposed magnets bias the needle component back towards the stowed configuration. Using a needle protection sleeve, the needle assembly can be removed from and/or installed onto a tattooing machine without requiring a user to come into direct contact with the needle assembly. By securing the needle protection sleeve to a support assembly, the removal and/or installation of the needle assembly becomes a one-hand operation.Type: GrantFiled: October 26, 2015Date of Patent: October 22, 2019Assignee: Painful Pleasures, Inc.Inventor: Zhao Juan

Patent number: 10448968Abstract: A follicle container for transporting an extracted hair follicle from a follicle extractor and containing the hair follicle for future use includes a receptacle, a conduit coupleable with the follicle extractor, to convey the extracted hair follicle toward the receptacle; and an injector to aerosolize and inject an irrigant into the conduit while the extracted hair follicle travels toward the receptacle. The irrigant lubricates the interior wall of the conduit and thus reduces friction as the follicle travels in the conduit. The irrigant also washes the conduit and keeps the extracted follicle moist and thus viable and more flexible. Flexibility allows the follicle to more easily suffer without damage bumps with the wall of the conduit and/or other extracted follicles as the follicle travels in the conduit.Type: GrantFiled: February 26, 2015Date of Patent: October 22, 2019Assignee: Infuez, LLCInventor: Scott Lewallen

Patent number: 10376255Abstract: A system for sealing a large penetration in the wall of a femoral artery comprises an occlusion catheter and an applicator. An access catheter may further be provided in order to facilitate introduction of the occlusion catheter. The occlusion catheter is introduced through a contralateral penetration, advanced over the aortic bifurcation, and an occlusion element on the occlusion catheter is positioned at the large diameter penetration. The occlusion element is then inflated to temporarily seal the large penetration while blood perfusion past the occlusion element is provided by the catheter. A sealing material, such as a tissue adhesive or other hemostatic agent is then introduced into a tissue tract above the large diameter penetration in order to seal the penetration. The occlusion element may be left in place while the sealing material has time to set, cure or otherwise form a permanent seal of the large penetration. The occlusion catheter and all access sheaths may then be removed from the patient.Type: GrantFiled: May 16, 2016Date of Patent: August 13, 2019Assignee: Cardiva Medical, Inc.Inventor: Zia Yassinzadeh
