Patent number: 10350061Abstract: Accordingly, embodiments of the present invention provide an IOL insertion device that facilitates the injection of the IOL in a controlled manner. The insertion device includes a front modular portion and an injector. The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal which has a longitudinal bore at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution (“BSS”) and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.Type: GrantFiled: November 11, 2016Date of Patent: July 16, 2019Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: Kevin R.

Patent number: 10349949Abstract: A closed loop-type hemostatic device having built-in inner pincers which integrates holding type pincers with a device for fitting a hemostatic clip, so as to: primarily, find and temporarily perform hemostasis on a bleeding portion by using holding type pincers after confirming that the bleeding portion exists; secondarily, move a clip pressing part and a clip pressing part and enclose the bleeding portion; and then move only the clip pressing part and clip a closed loop-type hemostatic clip onto the bleeding portion so as to perform hemostasis. The amount of bleeding can be reduced by temporary hemostasis on a bleeding portion, and a hemostatic clip can be precisely clipped on the bleeding portion, thereby improving hemostatic performance. Also, because hemostasis can be selectively performed only around a damaged blood vessel wall, therefore, the physiological benefit of being able to maintain partial blood flow may be provided.Type: GrantFiled: December 2, 2014Date of Patent: July 16, 2019Assignee: NATIONAL CANCER CENTERInventors: Sang Jae Park, Kwang Gi Kim, Seong Yeon Cho

Patent number: 10238487Abstract: Embodiments of the present disclosure provide a prosthetic heart valve and a heart valve delivery apparatus for delivery of the prosthetic heart valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. In one embodiment, a self-expanding valve comprises an expandable stent that is shaped to maintain the valve in the aortic annulus against axial without anchors or retaining devices that engage the surrounding tissue. A delivery apparatus for delivering s self-expanding prosthetic valve can be configured to allow controlled and precise deployment of the valve from a valve sheath so as to minimize or prevent jumping of the valve from the valve sheath.Type: GrantFiled: June 13, 2016Date of Patent: March 26, 2019Assignee: Edwards Lifesciences CorporationInventors: David Alon, Netanel Benichou, Oded Meiri
