  • Patent number: 9907684
    Abstract: This invention gives physicians in situ control to create differences in wall porosity between different areas of a stent wall. This enables a physician to customize the stent within a blood vessel to selectively block blood flow to an aneurysm with a low-porosity area of the stent wall, but allow blood flow to nearby branching vessels through one or more high-porosity areas of the stent wall. The method comprises inserting a stent into a blood vessel and, in situ, expanding the stent in a non-uniform manner, thereby causing one or more areas of the stent wall to have a lower post-expansion porosity than the rest of the stent wall. With this invention, physicians can selectively block blood flow into an aneurysm while maintaining blood flow into nearby branching vessels, even in tortuous and complex vessel configurations.

    Abstract: Harvesting of Bilateral internal thoracic arteries under direct vision, through a 2 inch left minithoracotomy, without robotic/thoracoscopic assistance and then using these arteries as a composite Y conduit for coronary artery bypass grafting has never been done or described before. The aim was to develop a technique, where bilateral internal thoracic arteries are harvested directly under vision via a 2 inch left minithoracotomy, without robotic/thoracoscopic assistance and complete off pump revascularization of the myocardium done using the internal thoracic arteries as a composite Y conduit. The “Nambiar Technique” which has never been done or described before, encompasses using a 2 inch left minithoracotomy through which the bilateral internal thoracic arteries are harvested directly under vision and multivessel total arterial coronary artery bypass grafting done using these conduits.

    Abstract: Adipose tissue has proven to serve as an abundant, accessible, and rich source of endothelial or vascular endothelial cells suitable for tissue engineering. We describe a detailed method for the isolation and purification of endothelial cells using purified enzymes and antibody-based selection. The cells can be obtained from liposuction procedures and used in vascular grafts.

  • Patent number: 8888834
    Abstract: A deployment assembly (10) for an introducer used for introducing into a patient a stent or other device, the deployment assembly including a housing 30 carrying a sprung loaded (90) actuator (44,50). The actuator includes a toothed wheel (50) carrying a spool (48) around which a retraction strap (44) can be wound. The strap (44) is coupled to a body member (26) of the introducer and through this to the outer sheath (14) thereof. A trigger (16) is provided for operating the actuator (44, 50). When the trigger (16) is pressed, the actuator winds, under the force produced by the spring (90), the strap (44) to thereby retract the outer sheath (14) so as to expose and then deploy the device carried on the introducer. The mechanism is such that a surgeon need not expend his own energy to retract the outer sheath (14) since this force is provided by the spring (90).

  • Patent number: 8882828
    Abstract: A stent-graft has a closed web end configuration in which endmost stent crowns do not extend beyond an end or edge of a tubular graft. In order to couple the stent-graft to tip capture fingers or prongs of a delivery system, the stent-graft includes a ring woven between the endmost crowns of an end stent. When end stent is in a compressed delivery configuration, sections of the ring between adjacent endmost crowns form attachment loops that longitudinally extend beyond the end of the tubular graft for engaging the tip capture fingers of a delivery system. When the end stent is in an expanded fully deployed configuration, the attachment loops retract back to the stent so that the ring is a circular band having a diameter substantially equal to the expanded diameter of the stent.

  • Patent number: 8852258
    Abstract: A catheter assembly includes a catheter, including an inner member and a sheath, extending from a handle. The handle includes a housing, a braking assembly, a carriage and a carriage driver. The braking assembly comprises a braking element within the housing interior and a braking element rotator. The carriage comprises at least one carriage braking surface engaging the braking element. The carriage driver, such as a spring, biases the carriage towards the proximal end of the handle. The inner member has a proximal end secured to the housing. The sheath has a proximal end secured to the carriage. Rotating the braking element causes the carriage to move proximally as the carriage braking surface slides along the braking element. This causes the sheath to move proximally relative to the inner member.

    Abstract: An endovascular perfusion stent graft is provided that can include a graft device, a balloon, and a perfusion port. The graft device can be configured to be inserted into a vessel. The balloon can be configured to temporarily restrict passage of air or fluid through the vessel when the balloon is temporary inserted into the graft device. The perfusion port can be configured to selectively allow passage of the fluid or the gas through the balloon and to the vessel. The perfusion port can be connected to another perfusion port or to a collection device, such as a heart lung machine. The vessel can be one of an ascending aorta, a descending aorta, or an arch of an aorta.

  • Patent number: 8821529
    Abstract: A device for occluding a septal defect is provided. In general, the occluding device has a contracted state that allows the occluding device to be received within a delivery device for deployment to the site of the defect and an expanded state that is achieved when the occluding device is deployed from the delivery device. The occluding device has a proximal portion, which may be substantially circular, a distal portion, which may be substantially ovaloid, and a connecting portion extending between the two. The distal portion may define first and second outer parts at opposite ends of the major axis, which may be bent or curved. The configuration of the proximal and distal portions allow the occluding device to securely engage the septal wall and be kept in position at the septal defect without causing substantial interference with the functioning of adjacent heart structures.

  • Patent number: 8808219
    Abstract: Implants and methods for treating ocular disorders are described. One method involves providing an elongated delivery device and an implant mounted at a distal end of the delivery device. An incision is formed in eye tissue and the implant is inserted the through the incision using the delivery device. The implant is implanted at a location communicating with a physiologic outflow pathway of an eye such that a distal end portion of the implant and a proximal end portion of the delivery device are relatively disposed in a non-linear orientation during implantation. In one method, the implant is non-linear after insertion.
