  • Publication number: 20240285331
    Abstract: Provided is an endoscopic vessel harvesting system comprising a direct current (DC) power control system connected to a therapeutic tool comprising a heating element. The DC power control system may include an input connection to receive power from a power supply. A first power control circuit may supply constant output power during a first time interval to heat the heating element to a target temperature. A second power control circuit may supply pulsed output power during a second time interval to maintain a temperature of the heating element within a target temperature range. An output connection may receive the output power and may supply controlled power to the heating element by supplying the constant output power during the first time interval, the pulsed output power during the second time interval, followed by a third time interval during which no power is supplied. Methods and systems are also disclosed.

  • Publication number: 20240173066
    Abstract: A surgical instrument for harvesting an organ includes a surgical tool and a handle. The handle includes an actuator rotatable about an actuator pivot pin and a cam connected to the actuator and rotatable in tandem with the actuator. The surgical instrument further includes an actuator rod having a distal end connected to the surgical tool and a proximal end connected to the cam. The cam defines a slot which captures a portion of the actuator rod. The portion of the actuator rod captured in the slot is slidable within the slot as the cam rotates. Sliding of the portion of the actuator rod in the slot actuates the surgical tool.

  • Patent number: 10143458
    Abstract: A method of preventing ingress of material into the left atrium of a heart includes providing a delivery sheath, advancing the sheath distal end through an opening between the right atrium and the left atrium of the heart, providing an expandable cage, delivering the expandable cage to the left atrium, and expanding the expandable cage within the left atrium. The expandable cage includes a proximal end, a distal end, and a plurality of supports extending therebetween. The expandable cage also includes a first membrane provided at its proximal end and a second membrane provided at its distal end. The expandable cage has a collapsed configuration so that it can be received within the lumen of the delivery sheath, and an expanded configuration for deployment within the heart. When expanded, the first membrane is positioned at an opening between the left and right atria of the heart, and the second membrane is positioned at the ostium of the left atrial appendage.

  • Publication number: 20180000617
    Abstract: A stent design reduces the likelihood of contact among structural members when the stent diameter is reduced before insertion into the body. In one approach, an undulating link has a J-shaped profile or has an angled portion on one side at the peak of the link, in order to reduce contact during crimping. The stent may also include structural features that improve such aspects as flexibility, the coatibility of a drug coating onto the stent, flare reduction, stent retention within the body and/or reduction of the minimum diameter of the stent during crimping.
