  • Patent number: 9179929
    Abstract: A laparoscopic scissor instrument can include a scissor assembly pivotally coupled to an elongate shaft. The scissor assembly can be formed of scissor blades having pivot posts thereon. The pivot posts can engage apertures on the elongate shaft, thus eliminating the need for a through-pinned pivot connection of the scissor blades. The scissor blades can also include actuation posts thereon. An actuation mechanism can include a slot to engage the actuation posts and open or close the blades of the scissor assembly. The scissor assemblies described herein can have a relatively low operational height such that they do not extend beyond a diameter of the elongate shaft during opening and closing of the scissor assembly.

  • Patent number: 9173675
    Abstract: A dermatome assembly is operable to harvest a skin graft and includes an ultrasonic dermatome and a power supply. The ultrasonic dermatome includes a body and an ultrasonic blade assembly mounted in the body. The blade assembly includes a frequency generator and a cutting horn powered by the frequency generator. The cutting horn is spaced apart from the body so that the body is restricted from damping vibrational movement of the cutting horn. The dermatome assembly is operable to precisely control the thickness of the cut skin graft and also restrict the cutting horn from overheating.

  • Patent number: 9173712
    Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue in a minimally invasive manner, often for treatment of congestive heart failure. In one embodiment, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface of the heart. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a delivery catheter. Delivering the anchor over the guidewire may provide improved control in the delivery and placement of the anchor within the right ventricle.

  • Patent number: 9161770
    Abstract: A surgical instrument can comprise an elongate tube including a camming rod and an actuation mechanism operably connected to the camming rod; a first jaw spine having a first cam slot; and a second jaw spine having a second cam slot, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin connected to the elongate tube. A camming pin rides along first and second interior camming surfaces and closes the jaw spines when the camming rod moves proximally. When the camming rod moves distally, a camming projection rides on first and second exterior camming surfaces on proximal sides of the first and second jaw spines and opens the jaw spines. One camming surface on each jaw spine facilitates closing the jaw spines while the other camming surface on each jaw spine facilitates opening the jaw spines. These two camming surfaces can be widely separated.
