Patent number: 9901364Abstract: Featured is a surgical instrument including a rotating cutting implement and a heat transfer mechanism configured to absorb heat energy during the use of such a rotating cutting implement. The heat transfer mechanism is configured so the absorbed heat energy is communicated to an external heat sink. Such a heat transfer mechanism includes a heat pipe, e.g., a scintered or wick type heat pipe. The heat energy is absorbed at one end of the heat pipe to minimize the potential for damage to the tissue and the like at and/or about the surgical site. Also featured are a surgical apparatus embodying such a surgical instrument and surgical or medical methods or procedures for manipulating, rotatably cutting, grinding, abrading or debriding tissue, bone or other structures or components of a mammalian body using such surgical instruments or surgical apparatus.Type: GrantFiled: February 17, 2015Date of Patent: February 27, 2018Assignee: Gyrus ACMI, Inc.Inventors: Kester J.

Patent number: 9877855Abstract: A method is provided for loading and delivering a self-expanding stent. The stent is compressed from its expanded diameter to a smaller delivery diameter. While compressed, the stent is pushed from the proximal end through the proximal end opening of a restraining sheath. The restraining sheath retains the stent in the delivery diameter. In order to deliver the stent, the proximal end of the stent is pushed and the restraining sheath is withdrawn proximally from the stent. As a result, the stent is released from the distal end opening of the restraining sheath.Type: GrantFiled: July 22, 2015Date of Patent: January 30, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: James Butler, Sean Cummins, Donagh O'Sullivan, Shane Holland

Patent number: 9877733Abstract: An anti-necrosis tourniquet device utilizes an air compressor, programmable through a microprocessor, to enable a user to set periodic cycles of increased and decreased pressure in a pressure cuff as a temporary measure to address a severely hemorrhaging wound on an extremity. When a situation arises to employ a tourniquet, the cuff is applied to a proximal region of the wound. The device is activated to increase pressure in the cuff to occlude the flow of blood to the wound for a programmed period of time after which the program decreases pressure in the cuff to supply blood to the wounded extremity for another selected time period to obviate necrosis of the tissue. This modulated cycle is repeated until a patient receives full medical treatment.Type: GrantFiled: July 7, 2015Date of Patent: January 30, 2018Inventor: Mohammad R. Jafary

Patent number: 9763651Abstract: A tendon stripper includes a stripping device and a rod. The stripping device includes a stripping member and at least one coupling member coupling to the stripping member. The stripping member has a blade portion and a separating portion separating the stripping member into several parts. The rod has a handle end and a coupling end opposite to the handle end. The coupling end couples to the coupling member of the stripping device. The separating portion allows the stripping member to be divided into first and second parts, and the first and second parts can be combined to each other to jointly receive the tendon. This avoids the generation of the incisions during the tendon transplantation. In addition, since the tendon stripper does not require any instrument for retaining the free end of the tendon, a convenient surgical procedure is provided.Type: GrantFiled: April 15, 2015Date of Patent: September 19, 2017Assignee: E-Da HospitalInventors: Chih-Kun Hsiao, Yuan-Kun Tu, Teng-Yao Yang, Feng-Chen Kao, Yi-Jung Tsai, Hao-Yuan Hsiao

Patent number: 9730626Abstract: A one-time/single use safety lancet system includes a body; a spring coupled to the body; a keeper having a deformable member; and a core for supporting a lancet and having an end coupled to the spring. The core further has a first latch for engaging the deformable member when the lancet system is in an armed state. The deformable member of the keeper is fractured after one use of the lancet system which prevents any subsequent arming of the lancet system. The keeper may be made part of the lancet body. The core may include a second latch, wherein the second latch permanently deforms or fractures the deformable member of the keeper after the single, one-time arming of the safety lancet system.Type: GrantFiled: January 28, 2015Date of Patent: August 15, 2017Assignee: INTRINSYK, LLCInventors: Paul Robert Fuller, James Keith Booker, Thomas Ralph Gannon
