摘要: A catheter delivered device to close a septal defect, the device comprising a cylindrical shaft of metal or polymeric material with concentric parallel cuts through the wall of the device which create flattened support struts. The center of the support struts move radially away from the axis in a hinge like fashion in response to the movement of the device's proximal and distal ends toward the center of the device. This movement is reversibly effected through mechanical means. The device can be coated with growth factors, mitogenic factors or other determinants which can improve tissue growth such that tissue ingrowth can occur over a period of time. The catheter itself may be an ultrasonic imaging catheter.

摘要: A method of bonding a bioglass layer to a metal substrate comprising heating the metal substrate having a roughened, oxidized surface to about a temperature at which the expansion of the metal is substantially equal to that of the bioglass at the temperature above which the thermal expansion of the bioglass is non-linear, immersing the heated metal surface in molten bioglass, the time of immersion being of such duration that the temperature of the metal does not rise substantially above the temperature to which it is heated, allowing the coated substrate to cool whereby the bioglass layer is bonded to the metal substrate by ion diffusion and thermo-mechanical stresses in the bioglass and metal layer are relieved at a substantially equal rate and the product produced by said process.

摘要: A method of maintaining airway patency in an airway of a patient. The method includes the steps of implanting a device into airway-forming tissue without affixing the device to the tissue and permitting a bioerodable portion of the device to bioerode to apply a force to the airway-forming tissue to maintain airway patency. The invention also provides devices for practicing the method.

摘要: A patient's obstructive sleep apnea is treated by identifying a patient with sleep apnea attributable at least in part to movement of a base of a tongue of the patient toward a pharyngeal wall of the patient. The tongue is stiffened by an implant sized to be placed within the tongue. A distal portion of the implant is sized to extend within the tongue from a first end near a mandibular-geniohyoid interface to a second end near a base of the tongue. A proximal portion is attached to the first end and adapted to be secured to a jaw bone of the patient following a period of healing after placement of the implant in the tongue.

摘要: A method and system for the creation or modification of the wear surface of orthopedic joints, involving the preparation and use of one or more partially or fully preformed and procured components, adapted for insertion and placement into the body and at the joint site. In a preferred embodiment, component(s) can be partially cured and generally formed ex vivo and further and further formed in vivo at the joint site to enhance conformance and improve long term performance. In another embodiment, a preformed balloon or composite material can be inserted into the joint site and filled with a flowable biomaterial in situ to conform to the joint site. In yet another embodiment, the preformed component(s) can be fully cured and formed ex vivo and optionally further fitted and secured at the joint site. Preformed components can be sufficiently pliant to permit insertion through a minimally invasive portal, yet resilient enough to substantially assume, or tend towards, the desired form in vivo with additional forming there as needed.

摘要: The invention disclosed herein relates to an implantable medical device for detection and treatment of syncope comprising an algorithm for determining the presence of syncope based on physiological activity associated with the onset of a syncopal episode, and a means for infusion a drug. Drug infusion therapy may be used along or in combination with pacing. The physiological activities detected and used by the device are selected from the group including changes in heart rate, heart rate variability, QT interval, PR interval, pressure, blood flow, vagal nerve activity, temperature, pH, and AV conduction times, respiration rate, position, motion, and combinations thereof. Drugs which may be used with the invention include pharmaceutical compositions which are capable of both endocardial administration and treatment of syncope, such as compositions comprising beta-blockers.
