  • Patent number: 10265046
    Abstract: An apparatus, system and methods that comprise adding a removable or detachable carrier containing a camera and illumination to a TEE probe, thereby allowing the user to view the placement of the probe and minimize or reduce the risk of esophageal and pharyngeal complications during the positioning of the TEE probe into the patient's esophagus. The reduction or minimization of complications occurs by allowing the cardiologist direct visualization of pharyngeal and esophageal structures during intubation. This device and procedure eliminate any “blind procedure”, whereby direct visualization of the pharyngeal structures and esophagus present a possible solution to these mechanical complications. Once the TEE probe has been properly positioned in the esophagus, the carrier is removed from the esophagus. The removable or detachable camera of the present disclosure can be used in other industries.

The capture tool 22 and the tissue support member 30 may each be independently moveable between a retracted position and an extended position. Partially retracting the capture tool 22 with the tissue support member 30 in the extended position gathers tissue 15 of the heart valve leaflet 2 between the capture tool and the tissue support member. A clip 55 may then be applied from the catheter assembly 12 to the gathered tissue 15 to hold the tissue substantially in a gathered configuration.

  • Patent number: 10058442
    Abstract: The present disclosure relates to catheters for delivering medical devices to a human patient's vasculature. A catheter comprises a sock which covers the medical device at the end of the catheter, and an introducer sheath which is reduced in diameter. This reduced diameter introducer sheath minimizes the crossing of the catheter.

  • Patent number: 10052128
    Abstract: A catheter extraction tool has a head that can be placed in position to significantly surround a diameter of a catheter. The head is shaped to have a low enough profile above the catheter to allow the head to be slid down the catheter and into a subdermal region in which the catheter is subdermal with respect to a patient. The head of the catheter extraction tool is expanded sufficiently to slide the head over a catheter cuff located in the subdermal region. After the head of the catheter extraction tool slides over the catheter cuff, the head is contracted to engage the catheter so that a user can pull the catheter out of the patient using the catheter extraction tool.

  • Patent number: 10045758
    Abstract: In some embodiments, a method includes releasably attaching an image capture assembly to a distal portion of a TEE device. Next, the TEE device coupled to the image capture assembly is inserted into an oral cavity of the patient. With the image capture assembly releasably attached to the distal portion of the TEE device, image data of an esophagus of the patient captured by the image capture assembly is displayed. While viewing the display of image data, the TEE device coupled to the image capture assembly can be moved within the esophagus. With both the TEE device and the image capture assembly disposed within the esophagus, the image capture assembly is detached from the TEE device. With the image capture assembly detached from the TEE device, and with the TEE device disposed at least in part within the esophagus, the image capture assembly is removed from the patient.

  • Patent number: 10034670
    Abstract: A detachment mechanism for an introducer assembly is designed to hold a coupling element of an implantable medical device until its desired release within a patient's vessel. The detachment mechanism includes a body portion having first and second gripper arm elements which grip onto the coupling element of the medical device. The gripper arms are naturally biased into a closed position by means of resiliency of the body element. For this purpose, an actuating device or opening element is provided which includes an enlarged head which can be pulled against tapering internal surface of the body portion of the detachment mechanism in order to force the gripper arms open, thereby to release the medical device from the introducer assembly. The detachment mechanism, being naturally in the closed configuration, reliably holds a medical device to the introducer assembly until it is desired to release the latter into the patient's vessel.

  • Patent number: 10028748
    Abstract: A catheter system for treating lesions is provided. The system is suitable for treatment of bifurcation lesions, has a low profile and provides substantially predictable translational and rotational positioning. In one embodiment, the system includes a fixed wire balloon catheter and a partially attached guidewire lumen, wherein the guidewire lumen is attached to the catheter at a crotch point. The location of the crotch point is predetermined so as to provide substantially predictable positioning. Several embodiments of the system are described for various types of lesions and vessel configurations.

  • Patent number: 10022255
    Abstract: A stent delivery system and methods are described. The stent delivery system can include an elongate outer member defining an outer member lumen through which a self-expanding stent is deliverable. The elongate outer member can include an anisotropic portion and a rigid portion proximal to the anisotropic portion. The anisotropic portion can be radially elastic and longitudinally inelastic. The rigid portion can be radially inelastic and longitudinally inelastic.

  • Patent number: 10016195
    Abstract: Methods and devices are provided for securing tissue to bone. In general, a suture leader can have leading and trailing ends, and an inner passageway configured to receive a strand of suture therein. More specifically, the trailing end of the leader can be configured to receive the strand of suture therein to form an overlapping region of suture leader and suture. When the suture is positioned in the leader, an outer diameter of the leading end of the leader can be less than an outer diameter of the over lapping region. The leader can have a lower bending stiffness than the suture so that the leader can be more easily folded into a bend. In certain aspects, the suture leader can be formed from a substantially flexible, braided material so that the leader can be configured to contract when a pulling force is applied to the leader. In another embodiment, the suture leader can have a pre-formed crease configured to mate with a threading tool.

  • Patent number: 10004513
    Abstract: An occlusion system can include an expandable implant that can be delivered to a bodily lumen. The implant can be carried on an engagement section of a catheter used in the system. The implant can be assembled onto the catheter by coupling a cover member of the implant with a support member of the implant. When assembled, the system can be advantageously configured to have a low delivery profile to facilitate delivery through catheters having a size of less than 7 Fr, and in some cases, less than 6 Fr.

  • Patent number: 10004623
    Abstract: A method of moving a stent device into an outer sheath of a stent device delivery system is disclosed. The stent device is crimped into a collapsed configuration onto the loading mandrel. The loading mandrel is pushed toward the outer sheath as the engaging surfaces resist relative longitudinal movement between the stent device and the loading mandrel to move the stent device into the outer sheath. Upon entering the outer sheath, the stent device expands radially until radially constrained by the outer sheath.
