  • Publication number: 20150133907
    Abstract: A system and method for inhibiting bleeding during surgical wound closure is provided. As the surgical wound created as part of surgery is closed by a suture and needle, energy is applied to the needle causing bleeding tissue to cauterize thus inhibiting at least some of the bleeding that invariably accompanies surgery. The surgical needle is held by a needle holder or other device and that device holding the needle is connected to an energy source that can be controlled by the surgeon. As energy from the energy source is applied to the needle holder through a conductive line, it is conveyed to the surgical needle through the needle holder and the energy emanating from the needle cauterizes tissue and controls bleeding as the wound is sutured closed. Bleeding from the needle tract created by the puncture of the tissue by the sharp point of the needle and passage of the needle body into the tissue that would otherwise occur as a necessary part of suture is in particular inhibited.

    Abstract: Ablation catheters and systems include multiple inline chambers for containing and heating an ablative agent. The heating chamber includes one or more channels to increase the contact surface area of the ablative agent with the walls of the heating chamber to provide more efficient heating. Induction heating is used to heat a chamber and vaporize a fluid within by wrapping a coil about a ferromagnetic chamber and providing an alternating current to the coil. A magnetic field is created in the area surrounding the chamber which induces electric current flow in the chamber, heating the chamber and vaporizing the fluid inside. Positioning elements help maintain the device in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.

    Abstract: A medical heating device is based on an electrical heater formed out of a self-limiting conductive material, such as a conductive polymer or ceramic. An electrical resistance that gradually changes with temperature characterizes the material such that heat production from electrical current through the material varies with temperature. A thermally insulating jacket contains the self-limiting heater element, which can be coupled to an electrical power supply. A probe thermally coupled to the heater extends outward from the jacket. The self-limiting medical heating device can be used by touching the end of the probe to target tissue, such as skin, adipose tissue, nerves, glands, vascular tissue, or abnormal growths or tumors to effect the desired treatment, typically by thermally ablating, cutting, or shrinking the target tissue where touched by the probe or in the vicinity therein.

    Abstract: An electrical conductor, such as a wire or catheter, which is coated circumferentially with a ferromagnetic material in a selected region, is fed from a high frequency alternating current source. The ferromagnetic material has a quick response in heating and cooling to the controllable power delivery. The ferromagnetic material can be used for separating tissue, coagulation, tissue destruction or achieving other desired tissue effects in numerous surgical procedures.

  • Patent number: 7789876
    Abstract: An electrode catheter is introduced into a vein or other hollow anatomical structure, and is positioned at a treatment site within the structure. The end of the catheter is positioned near a junction formed in the structure. This junction can be the sapheno-femoral junction. The position of the catheter near the junction is determined based on a signal from a device associated with the catheter within the structure. A fiber optic filament which emits light is used with the catheter or a guide wire over which the catheter is advanced. The light is visible externally from the patient. The light dims and may no longer externally visible at the sapheno-femoral junction where the catheter moves past the deep fascia and toward the deep venous system. The position of the catheter can be determined based on this external observation.

  • Publication number: 20100030205
    Abstract: A portable, thermal cauterizing forceps device for use in surgery. The device incorporates a pair of ceramic heater elements mounted within the tips of the tines of a forceps. The forceps is used to grasp tissue or blood vessels and apply heat to effect cauterization. In the case of the first embodiment of the invention, the forceps instrument incorporates a battery and control electronics. The thermal-forceps is of a self-contained wireless, handheld disposable design. In a second embodiment of the invention, the forceps handpiece is connected to an external power source. Both embodiments of the forceps incorporate set of rapidly heating ceramic heater elements that may be composed of silicon nitride. An LED provides the operator feedback as to the operating level of the heaters and/or battery reserve. Enhancements to the second embodiment include a rechargeable power supply, variable control of the heater temperature, as well as a, digital display of the tip temperature.

  • Publication number: 20090234347
    Abstract: An instrument and method are provided for sealing and joining or hemostatically dividing tissue, which is particularly suitable for laparoscopic and endoscopic surgery. The instrument makes use of the controlled application of a combination of heat and pressure to seal adjacent tissues, to join adjacent tissues, or to anastomose tissues, whereby tissue is heated for an optimal time and at an optimal temperature under optimal pressure to maximize tissue seal strength while minimizing collateral tissue damage. The instrument of the present invention is lightweight and therefore portable, and is particularly useful in field conditions where a source of external power may not be readily available.

  • Patent number: 7128741
    Abstract: Systems, methods, and instruments associated with controlling the operating modes of an electrosurgical instrument using control signals delivered in a wireless manner from the electrosurgical instrument to an electrosurgical generator. The electrosurgical instrument transmits wireless control signals to the electrosurgical generator to initiate delivery of electrosurgical energy. The control signals are delivered to the electrosurgical generator without the need for a conductive cord extending between the electrosurgical generator and the electrosurgical instrument. The energy is delivered to the electrosurgical instrument, in response to the wireless control signals, along a path through an electrode and the physician utilizing the electrosurgical instrument and/or a conductive path external to the physician. The electrode upon which the physician rests provides a path for the electrosurgical energy and optionally prevents burning of the physician during an electrosurgical procedure.

  • Patent number: 7048746
    Abstract: Novel suture removal instrument and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and/or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.
