  • Patent number: 10595899
    Abstract: Automatic dilator devices for generating minimally invasive access apertures for surgical procedures or endoscopic surveillance. The automatic dilators comprise a number of spreader tubes nested one inside the other. The devices deploy automatically by means of coupled mechanical mechanisms which insert one spreader after the other distally into the patient's tissue. Each spreader moves distally into the tissue by means of a screwing action, by which rotation is converted into linear motion of the neighboring spreader, immediately external to it, by means of interaction between a helical thread form on a surface of a spreader being engaged by a section of thread, or by one or more protrusions on the opposing face of the next spreader external to the rotating spreader. Such a combination of helical thread and follower enables a rotatory mechanism to be used to deploy one nested spreader tube after the other, by continuous rotary motion.

  • Patent number: 10307240
    Abstract: Methods and apparatus for use in capturing embolic debris during a surgical procedure in a patient are provided. The methods include utilizing an embolic capture device that is configured for delivery into a patient via a transapical delivery approach and via an arterial delivery approach, and determining which of a transapical delivery approach and an arterial delivery approach should be used with the patient. The methods also include inserting the embolic capture device within a delivery system, and deploying the embolic capture device at a desired location within the patient's blood vessel that is downstream from the location of the surgical procedure. The same embolic capture device is configured for use with a transapical delivery approach and an arterial, such as a transfermoral, delivery approach.

  • Patent number: 10278719
    Abstract: Catheter-delivered endovascular medical devices are described. The devices may include a pull wire attached to a distal body, which may be formed of a basket or other framework that has a plurality of cells. The pull wire may be extra long to allow a secondary device, such as an aspiration catheter, balloon or stent, to be delivered over the pull wire while the pull wire is in an intracranial artery. Methods of using and making the devices are also described.

  • Patent number: 10258492
    Abstract: A prosthesis delivery system and method of use thereof are described. The system includes a handle, an inner cannula extending proximally from the handle, an outer sheath extending proximally from the handle, and a pull member. The outer sheath including an axially collapsible segment and a non-collapsible body. The pull member is coupled between the handle and the axially collapsible segment or the non-collapsible body of the outer sheath. The handle is operable to retract the pull member such that the axially collapsible segment is shortened. The handle may include a spool and an actuator coupled to the pull member in a manner for winding the pull member around the spool. The handle may be shorter than the retraction length of the axially collapsible segment sized for deployment of the prosthesis.

  • Patent number: 10238339
    Abstract: This invention relates to an implantable device for a physiologic sensor, comprising an implantable expandable anchor, a bridge on which the sensor is secured, as well as an optional adapting ring. The invention also relates to a method of monitoring bodily functions using the anchor and sensor. The anchor is compressed and the bridge assumes an elongated shape during delivery to a target lumen. Upon deployment at the target site, the anchor expands and the bridge bows into the interior lumen of the expanded anchor, distancing the sensor from the vessel wall. This invention also relates to a method of manufacturing said device and a method of implanting a sensor.

  • Patent number: 10201446
    Abstract: An apparatus comprises a sleeve, a seal, and an anchor assembly. The sleeve is flexible and non-permeable and is configured to fit in a duodenum. The seal is positioned at the proximal end of the sleeve and is configured to seal the proximal end of the sleeve against the stomach mucosa, the pylorus, or the duodenum mucosa. The anchor assembly comprises a pair of atraumatic anchor ends and a resilient member positioned between the anchor ends. At least a portion of the resilient member extends along at least a portion of the length of the sleeve. The resilient member is configured to bias the anchor ends generally toward each other, to thereby substantially anchor the sleeve in the duodenum. The sleeve is configured to prevent chyme from contacting the mucosa of the duodenum; and to prevent enzymes excreted in the duodenum from mixing with chyme in the duodenum.

  • Patent number: 10201336
    Abstract: A device and method for delivering a vascular device to a target site is provided that allows an orientation of the vascular device at the target site to be adjusted by a user. In general, the delivery device includes an outer tubular member, an intermediate tubular member within the outer tubular member, and an inner member that can move axially within the intermediate tubular member. Each of the members defines a proximal end and a distal end. The intermediate and outer tubular members are fixed at their respective proximal ends, but are not fixed at their distal ends. Thus, a torque applied to the proximal end of the intermediate tubular member is at least partially transmitted to the distal end of the intermediate tubular member, allowing the user to rotate an attached vascular device by rotating the proximal end of the intermediate tubular member.
