  • Patent number: 8202314
    Abstract: A holder for a flexible leaflet prosthetic aortic heart valve that is less bulky than earlier holders and minimizes obstructions to vision and working space around the valve to facilitate implantation thereof. The holder may have a central hub and three outwardly extending legs that connect directly and exclusively to tips of the commissures of the aortic heart valve for better tactile feedback when parachuting and seating the valve in the annulus. The legs are sized so that they do not overlap the commissure tips and therefore afford a better view of the sewing ring adjacent the commissures. The legs may be narrow in the midsection or split into two rails to increase visibility of the valve leaflets. The hub may be vaulted axially upward relative to the outer ends of the legs to further increase visibility of the valve.

  • Patent number: 8150499
    Abstract: An automatic atherectomy system uses a rotary burr at the tip of a catheter as a sensing device, in order to measure both electrical conductivity and permittivity of surrounding tissue at multiple frequencies. From these parameters it is determined which tissue lies in different directions around the tip. A servo system steers the catheter tip in the direction of the tissue to be removed. In non-atherectomy applications the rotary burr can be replaced with any desired tool and the system can be used to automatically steer the catheter to the desired position. The steering may be done hydraulically, by pressurizing miniature bellows located near the catheter tip.
