  • Publication number: 20190167122
    Abstract: A system for monitoring the flow of blood within an endoluminal passage is provided comprising a medical device and a sensor. The medical device is implantable within the endoluminal passage and includes a shaft and an expandable segment coupled to the shaft. The expandable segment is movable between a first state and a second state. Movement of the expandable segment is responsive to a change in the fluid pressure external to the expandable segment. The sensor is positioned on the medical device and is adapted to collect information associated with the state of the expandable segment.

  • Patent number: 10035084
    Abstract: The invention relates generally to a de-aeration apparatus and system, and more particularly, to an apparatus and system suitable for de-aerating highly viscous fluids comprising a vacuum chamber, an annular disk for rotating within the chamber, and a fixed baffle covering a portion of the surface of the annular disk and thereby defining a predetermined path by which the fluid to be de-aerated is spread more quickly into a thinner layer on the disk, exposing a greater amount of air/gas bubbles from the fluid in a shorter amount of time and resulting in a higher quality product than conventional de-aeration systems allow.

  • Publication number: 20140277351
    Abstract: A multistage balloon catheter that uses a single lumen to inflate a balloon in stages is disclosed. A fluid port provides fluid communication from an inflation lumen in the balloon catheter to the inner volume of a distal balloon. The distal balloon expands as fluid in delivered to the inner volume of the distal balloon. Once inflated, the pressure continues to rise until a threshold pressure is exceeded. A pressure sensitive inflation valve provides fluid communication into an inner volume of a second balloon disposed at least partially proximal to the distal balloon. The pressure sensitive valve allows fluid communication into the second balloon once the threshold pressure is reached in the first balloon thereby inflating the second balloon.

  • Patent number: 8308692
    Abstract: In at least one embodiment of the present invention, an introducer for use in inserting a medical device into a body vessel of a patient is provided. The introducer comprises a housing having a proximal opening, a distal opening and a chamber extending therebetween. A seal in diaphragm form is disposed in the chamber. The seal is formed of polymeric material having a first phase transition temperature higher than about body temperature and a second phase transition temperature that is less than the first phase transition temperature but is greater than about room temperature. The seal is in a first configuration and has an opening formed therethrough when at about room temperature for advancing the medical device through the seal. The seal self-configures to a second configuration when at a temperature of at least the second phase transition temperature for obstructing the body fluid from flowing through the opening of the seal.

  • Publication number: 20120180787
    Abstract: A device for dilating an opening through the tracheal wall of a patient includes a loading dilator. A balloon catheter is received in the lumen of the dilator such that the balloon extends distal to the loading dilator distal end. The balloon is configured to radially dilate a portion of the tracheal wall upon inflation. The balloon includes retention structure along its outer surface such that upon inflation, the retention structure inhibits dislodgement of the balloon when the balloon is positioned across the tracheal wall. The retention structure may comprise a pair of spaced elements radially projecting from the outer surface of the balloon, and spaced along the outer surface such that each of the elements is disposed at an opposite side of the tracheal wall when the balloon is positioned along the tracheal wall opening.

  • Publication number: 20120165915
    Abstract: A deployment device for repair of a transected body vessel is described herein. Device can have a handle and one or more shafts coupled thereto. A prosthesis being retained by a sheath can be coupled to the delivery device. The sheath can have end portions coupled to one or more shafts. Rotation of a shaft can retract a sheath portion away from either end of the prosthesis for expansion thereof prior to the middle of the prosthesis. Continued rotation of a shaft can completely remove the sheath from the prosthesis, so that the prosthesis is fully expanded and couples the first and second vessel portions of the transected vessel together. Prosthesis may be retained by overlapping a tubular sheath and lacing a threading member therethrough. Prosthesis may be retained by a splittable sheath.

  • Publication number: 20120157854
    Abstract: Systems and methods for gaining percutaneous access to a body lumen, preferably without a guidewire, are provided herein. The system can include a tubular medical device and a needle with a distal tip. A side port is provided through a wall of the tubular medical device, to be in communication with a distal end opening of the device via a passageway. The needle can be positioned within the side port to extend the distal tip beyond the distal end opening. In this position, the distal tip can form an entry opening in the body lumen, and a distal portion of the device can be advanced over the indwelling needle into the entry opening. The needle can then be withdrawn from the tubular medical device, while maintaining a portion of the tubular medical device in place within the body lumen.

  • Publication number: 20120158035
    Abstract: Coaxial balloon catheters are described herein. The balloon catheter can include outer and inner tubes in a coaxial relationship, with a balloon attached to an end thereof. A support sleeve can be disposed around the inner tubular member proximate the proximal end of the balloon. The support sleeve can have a channel formed therein to communicate with an inflation lumen and a balloon interior. The channel may be formed by separation of two longitudinal edges extending through the support sleeve. The support sleeve can include an outward extending portion that is sized to engage the distal end of the outer tube in order to limit relative movement between the inner and outer tubes.
