| 20090069786 | Medical apparatus and method for facilitating the management of long term tunneled conduits - A method and apparatus for facilitating the management of indwelling conduits to avoid and/or treat infections associated with long term implantation. A sleeve carrying a layer of porous material on its outer surface is percutaneous implanted to place the layer of porous material just under the patient's outer skin in contact with the patient's dermis where it functions to promote soft tissue ingrowth. A catheter passes through the sleeve passageway and along an interior body path to an interior destination site, e.g., an opening into a vein, i.e., venotomy site. Within about 3-6 weeks after implantation, the patient's dermal tissue integrates sufficiently with the sleeve porous material to physically anchor the sleeve and create an infection resistant barrier. Further, a tunnel, characterized by an epithelialized capsule, typically forms around the catheter along the interior body path extending to the interior destination site. After sufficient integration of the patient's soft tissue into the porous layer, the sleeve passageway can be used to pass various procedural tools to the tunnel and interior destination site without disturbing the tissue integrating barrier. | 03-12-2009 |
| 20090105545 | Apparatus and method for facilitating the implantation of a medical device - An apparatus and method for facilitating the implantation of a medical device through an incision so as to promote soft tissue ingrowth into a biocompatible porous layer, e. g, titanium, carried on the periphery of the medical device. The method utilizes an incision (either percutaneous or subcutaneous) which is intentionally undersized by 10-20% relative to the width dimension of the porous layer. Accordingly, a physician must stretch the surrounding tissue to maximize the size of the opening to insert the device. Because the opening is undersized relative to the porous layer, the surrounding tissue remains physically stressed, i.e., radially and/or circumferentially, and acts to enhance cell proliferation and healing. A surgical cutting tool is preferably provided to assist the physician to form a properly dimensioned opening. | 04-23-2009 |
| 20090171295 | Enhanced apparatus for percutaneous catheter implantation and replacement - A medical apparatus and method of use for implanting a percutaneous catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve having a tapered forward portion to facilitate its insertion through an undersized incision. The sleeve provides an interior elongate passageway which extends from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway is dimensioned to snugly accommodate the outer surface of catheter while permitting the catheter to slide relative to the sleeve. A sealing device is mounted around the catheter adjacent to the sleeve proximal end to prevent deleterious material from migrating into the patient's body along the catheter outer surface. A locking member secured to the sleeve can be pivoted to an unlocked portion for permitting axial and rotational movement of said catheter relative to said sleeve and or to a locked position for preventing such relative movement. | 07-02-2009 |
| 20100036238 | DEVICE AND METHOD FOR ASSESSING EXTENSION OF A DEPLOYABLE OBJECT - A medical instrument assembly is disclosed. The medical instrument has proximal and distal ends. A receiver coil being mounted proximate to a distal end of the medical instrument, the receiver coil being electrically connectable at a proximal end of the medical instrument. A deployable object being disposed and movable within the medical instrument. The deployable object bearing a high magnetic permeability material located proximate to the receiver coil. The high magnetic permeability material and the receiver coil combining to form an inductive element having an inductance that varies in a predetermined manner with the position of the deployable device relative to the receiver coil. A determination of the inductance being performed at the proximal end of the delivery catheter indicates the extension of the deployable device through the medical instrument. | 02-11-2010 |
| 20100114137 | SURGICAL INSTRUMENT HAVING AN ARTICULATED JAW STRUCTURE AND A DETACHABLE KNIFE - A surgical instrument with articulated jaw structure includes a frame and two jaws. The jaws have proximal portions that are mounted to each other for movement in a substantially parallel relation between a fully open position wherein the jaws are separated for receiving tissue therebetween and an approximated position wherein the jaws are closer together. Preferably, the jaws are in the fully open position when the distal portion of at least of the jaws is located in an extended position and are in the approximated position when the distal portion of the extended jaw or jaws is located in a retracted position. The surgical instrument may further include a detachable knife assembly and knife actuating mechanism. | 05-06-2010 |
| 20100150391 | Planar Flexible Voice Coil Suspension - A voice coil suspension system comprising a spider formed of flexible dielectric material defining a flexure portion configured to suspend a voice coil for axial displacement and an elongate connector portion for carrying flat electrical conductors for electrically connecting terminals of said voice coil to stationary electric contacts. | 06-17-2010 |
| 20100234814 | Method and Subcutaneous Apparatus for Facilitating the Replacement of an Implanted Catheter - A medical apparatus and method of use for implanting a catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve intended to be subcutaneously implanted. The sleeve comprises a wall surrounding an interior elongate passageway which extends from a sleeve proximal end to a sleeve distal end. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway includes a sealing nib dimensioned to engage the outer surface of the catheter while permitting the catheter to slide relative to the sleeve. The sealing nib prevents deleterious material from migrating into the patient's body along the catheter outer surface. | 09-16-2010 |
| 20110004287 | Bifurcated Stent and Delivery System - Systems for delivering a bifurcated stent to a bifurcation site comprise catheters and/or bifurcated stents delivered therefrom. | 01-06-2011 |
