  • Patent number: 8133184
    Abstract: A method for performing an in-vivo calibration of a blood pressure sensor that is associated with a balloon of an in-vivo balloon system, the sensor and balloon being associated such that the sensor is in-vivo when the balloon is in-vivo. The balloon is inflated so that a gas pressure in the balloon system is indicative of a patient's blood pressure. The patient's blood pressure is monitored through two channels, the gas pressure and the sensor. The blood pressure measurements obtained by monitoring the gas pressure are used as reference, or “true,” blood pressure measurements to determine a mathematical relationship between blood pressure measurements obtained through the sensor and the reference blood pressure measurements. In this manner, future blood pressure measurements obtained through the sensor can be modified according to the mathematical relationship to generate calibrated blood pressure measurements.

  • Patent number: 8038623
    Abstract: A method for performing an in-vivo calibration of a blood pressure sensor that is associated with an in-vivo balloon system. The method involves monitoring a patient's blood pressure by observing the system gas pressure while at the same time monitoring the patient's blood pressure through the sensor. The blood pressure measurements obtained by monitoring the system gas pressure are used as reference, or “true,” blood pressure measurements, and an “offset” is determined between the reference blood pressure measurements and the blood pressure measurements obtained through the sensor. The offset can be stored in a memory, which may also store sensor sensitivity data. The offset and/or sensitivity data may be used to adjust future measurements obtained from the sensor, thereby generating calibrated sensor measurements.

  • Patent number: 8034009
    Abstract: A dressing for applying compression to a wound in a patient includes a bladder having a non-deformable end wall and a deformable membrane. The dressing may include a flexible web having an adhesive layer on one side thereof for securing the dressing to the patient so as to hold the bladder against the patient's skin. Upon inflation, the deformable membrane projects towards the patient's skin and exerts pressure on the wound to reduce the flow of blood from the wound.

  • Publication number: 20090060743
    Abstract: An impeller includes a hub, and a plurality of blades supported by the hub, the blades being arranged in at least two blade rows. The impeller has a deployed configuration in which the blades extend away from the hub, and a stored configuration in which at least one of the blades is radially compressed, for example by folding the blade towards the hub. The impeller may also have an operational configuration in which at least some of the blades are deformed from the deployed configuration upon rotation of the impeller when in the deployed configuration. The outer edge of one or more blades may have a winglet, and the base of the blades may have an associated indentation to facilitate folding of the blades.

  • Publication number: 20080243182
    Abstract: A hemostasis device for percutaneously sealing a puncture in the wall of a blood vessel includes a rigid post, and a foot, a seal and a retaining member mounted on the rigid post. The hemostasis device may be deployed in the puncture so that the foot is positioned within the blood vessel. Tension is applied to the rigid post to hold the foot against the inside surface of the blood vessel. The retaining member is then pushed along the length of the rigid post, advancing the seal to a deployed state against the outside surface of the blood vessel. The puncture in the blood vessel is sandwiched between the foot and the seal in the deployed state. The rigid post, foot, seal and retaining member may all be formed from a resorbable polymeric material.

  • Publication number: 20080114339
    Abstract: An impeller includes a hub and at least one blade supported by the hub. The impeller has a stored configuration in which the blade is compressed so that its distal end moves towards the hub, and a deployed configuration in which the blade extends away from the hub. The impeller may be part of a pump for pumping fluids, such as pumping blood within a patient. A blood pump may include a cannula having a proximal portion with a fixed diameter, and a distal portion with an expandable diameter. The impeller may reside in the expandable portion of the cannula. The cannula may have a compressed diameter which allows it to be inserted percutaneously into a patient. Once at a desired location, the expandable portion of the cannula may be expanded and the impeller expanded to the deployed configuration. A flexible drive shaft may extend through the cannula for rotationally driving the impeller within the patient's body.

  • Publication number: 20080077178
    Abstract: A device is proposed for inserting hemostatic material through a tissue channel and against the wall of a blood vessel of a patient, wherein the blood vessel wall has a puncture therein adjacent the tissue channel. The device includes a charge of hemostatic material and a hollow sheath adapted to pass through the tissue channel, the sheath having a cross sectional profile larger than the puncture. The device places the hemostatic material in the hollow sheath and advances the hemostatic material through the sheath to the vessel wall around the puncture.

  • Patent number: 7250025
    Abstract: In order to fully automate the inflation timing and deflation timing of an intra-aortic balloon pump, certain delays intrinsic in the system must be taken into account. A process for calculating these delays includes determining a nominal inflate command time, adding a dither time interval to the nominal inflate command time to obtain an actual inflate time, and determining a deflate command time. An inflation/deflation cycle is then processed in which the intra-aortic balloon pump is inflated at the actual inflate command time and deflated at the deflate command time. Blood pressure data is acquired from the patient during the inflation/deflation cycle, and is then analyzed to determine a realization time at which the effects of inflating the intra-aortic balloon are realized on the blood pressure waveform. From this the total delay time between the actual inflate command time and the realization time can be determined.

  • Patent number: 7229403
    Abstract: A balloon catheter has a balloon membrane, a tip connected to the distal end of the balloon membrane and an outer tube connected to the proximal end of the balloon membrane for supplying a medium for inflating and deflating the balloon membrane. A pressure sensor, such as a fiber optic sensor, may be mounted in a pocket in the tip. The pocket may be filled with a flexible substance which both communicates pressure to and protects the pressure sensor. A membrane may overlie the pocket to prevent leakage of the flexible substance therefrom.
