20090008076 | Systems and Methods For Base Station Enclosures - A technique for climate control of, for example, base station circuitry within an enclosure involves placing base station circuitry within the enclosure and controlling the climate therein. A system according to this technique includes an enclosure suitable for use outside in a wide range of extreme weather conditions. A controller may, for example, control a fan tray with a heater to pull ambient air through a filtration unit, through the fan tray where the air is heated, and through cold start recirculation dampers. | 01-08-2009 |

20110012489 | RACK SYSTEM - A rack system for housing electronic and/or electrical equipment is provided comprising a rectangular base frame, a rectangular top frame, and four elongated vertical support members each extending along a longitudinal axis between and joined to two associated corners of the rectangular base frame and the rectangular top frame. The rectangular base frame, rectangular top frame, and the four elongated vertical support members may be constructed from members having the same substantially A-frame cross-section. Each support member may be constructed from an elongated sheet material extending along a longitudinal axis by bending the sheet material about an axis parallel to the longitudinal axis of the sheet material to form at least three elongated sections, where a first section and a second section are adjacent and substantially perpendicular to each other and a third section extends between approximately mid-point of the first section and approximately mid-point of the second section. | 01-20-2011 |

20080287944 | TISSUE ABLATION APPARATUS AND METHOD - A method and apparatus for carrying our thermal ablation of target tissue is disclosed. The apparatus includes an RF ablation device having a multi-electrode electrode assembly designed to be deployed in target tissue, defining a selected-volume tissue region to be ablated, and having infusion channels for infusing a liquid into the target tissue during the ablation process. A control unit in the apparatus is operably connected to an RF energy source, for controlling the RF power level supplied to the electrodes, and to an infusion device, for controlling the rate of infusion of a liquid through the device into the tissue. During both electrode deployment and tissue ablation, impedance and or temperature measurements made within the tissue are used to control the RF source and infusion device, for optimizing the time and extent of tissue ablation. | 11-20-2008 |
20090275978 | SELF-TENSIONING VASCULAR OCCLUSION DEVICE AND METHOD FOR ITS USE - The present invention advantageously provides self-tensioning occlusion devices, systems, and methods for percutaneous access and closure of vascular puncture sites. One device comprises a catheter body having a proximal end and a distal end, an occlusion member, and a tensioning member. The occlusion member, such an expansible member, is disposed on a distal end of the body. The tensioning member, such as a spring or coil, is slidably disposed over the body and proximal the expansion member. Generally, during application, the tensioning member will be positionable against subcutaneous tissue so as to lodge and anchor the expansible member against the puncture site. In particular, the expansible member allows for sealing of the puncture site while the tensioning member applies and maintains tension to the expansible occluder so that it is seated against the puncture site at a vascular surface. | 11-05-2009 |
20100145383 | DRUG ELUTING VASCULAR CLOSURE DEVICES AND METHODS - Drug eluting vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. The devices and methods rely on a combination of the body's own natural mechanism to achieve hemostasis with bio-chemical agents to accelerate the hemostatic process. One method includes the steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A bio-chemical sealing member disposed proximal the expansible member is then displaced so as to expose a bio-chemical region or release region of the device. At least one bio-chemical agent is thereafter released from the device and into the tissue tract to accelerate the occlusion process in the tract. | 06-10-2010 |
20100168767 | APPARATUS AND METHODS FOR DELIVERING HEMOSTATIC MATERIALS FOR BLOOD VESSEL CLOSURE - Apparatus for sealing a vascular wall penetration disposed at the end of the tissue tract comprises a shaft, an occlusion element, a hemostatic implant, and a protective sleeve. The apparatus is deployed through the tissue tract with the occlusion element temporarily occluding the vascular wall penetration and inhibiting backbleeding therethrough. The hemostatic implant, which will typically be a biodegradable polymer such as collagen carrying an anti-proliferative agent or coagulation promoter, will then be deployed from the sealing apparatus and left in place to enhance closure of the vascular wall penetration with minimum scarring. The implant may be radiopaque to allow observation before release. | 07-01-2010 |
20110022081 | HEMOSTASIS-ENHANCING DEVICE AND METHOD FOR ITS USE - The present invention advantageously provides devices, systems, and methods for percutaneous access and closure of vascular puncture sites. In an embodiment, the device for enhancing the hemostasis of a puncture site in a body lumen or tract comprises a catheter having one tubular member having a proximal end and a distal end with one inner lumen extending between at least a longitudinal portion of the catheter tubular member. The one tubular member includes external and internal tubular bodies each having proximal and distal ends. At least one of the external and the internal tubular bodies is longitudinally movable with respect to the other. An expansible member with proximal and distal ends is disposed on the distal end of the one tubular member. The distal end of the expansible member is connected to the distal end of internal tubular body and with its proximal end connected to the distal end of external tubular body. | 01-27-2011 |
20120029436 | BILATERAL VESSEL CLOSURE - A system for sealing a large penetration in the wall of a femoral artery comprises an occlusion catheter and an applicator. An access catheter may further be provided in order to facilitate introduction of the occlusion catheter. The occlusion catheter is introduced through a contralateral penetration, advanced over the aortic bifurcation, and an occlusion element on the occlusion catheter is positioned at the large diameter penetration. The occlusion element is then inflated to temporarily seal the large penetration while blood perfusion past the occlusion element is provided by the catheter. A sealing material, such as a tissue adhesive or other hemostatic agent is then introduced into a tissue tract above the large diameter penetration in order to seal the penetration. The occlusion element may be left in place while the sealing material has time to set, cure or otherwise form a permanent seal of the large penetration. The occlusion catheter and all access sheaths may then be removed from the patient. | 02-02-2012 |
