  • Patent number: 10307248
    Abstract: A medical device includes an expandable conduit, a prosthetic heart valve and a delivery device, including a balloon catheter. The expandable conduit may include one or more inner or outer sleeves supported by a frame or stent. The sleeve(s) may be a bioprosthetic tissue wrapped, molded or sewn about the frame or stent. Coupled to an end of the expandable conduit is the prosthetic heart valve. The conduit and heart valve may be crimped on the balloon catheter for percutaneous deployment. The frame may be constructed of a balloon-expandable material for the conduit portion and a self-expandable material for the prosthetic heart valve portion. The prosthetic heart valve is anchored at the native heart valve and then the conduit to be expanded into place to protect the aorta. The self-expanding prosthetic heart valve avoids the need for balloon mounting. This provides for a smaller diameter and easier delivery.

  • Patent number: 9931121
    Abstract: A nerve repair conduit configured to be secured on first and second portions of a selected nerve. The nerve repair conduit includes a polymeric body having a proximal end, a distal end, an exterior surface and an interior surface defining an interior lumen. In addition, the nerve conduit includes at least one drug reservoir to hold agent(s) that may, for example, facilitate nerve regeneration. The drugs diffuse from the drug reservoir(s) into the nerve repair conduit through an outlet (e.g., a semipermeable membrane) in proximity to the first and second portions of a selected nerve. The nerve repair conduit may be configured to deliver the agent(s) at a rate having substantially zero-order kinetics and/or at a constant rate over a selected period of time (e.g., at least 1 week).

  • Patent number: 9924948
    Abstract: Methods, devices and systems facilitate gastric retention of a variety of therapeutic devices. devices generally include a support portion for preventing the device from passing through the pyloric valve or esophagus wherein a retaining member may optionally be included on the distal end of the positioning member for further maintaining a position of the device in the stomach. Some embodiments are deliverable into the stomach through the esophagus, either by swallowing or through a delivery tube or catheter. Some embodiments are fully reversible. Some embodiments self-expand within the stomach, while others are inflated or otherwise expanded.

  • Patent number: 9919128
    Abstract: A catheter can efficiently transmit an operator's pushing force to a distal end of the catheter with a reduced risk of getting caught at a curved region of a lumen (e.g., a blood vessel, bile duct, pancreatic duct or the like). The catheter includes a first core wire and a second core wire disposed between an inner tube and an outer tube. The second core wire can move to an optimal position depending on external forces exerted at a curved region of the lumen when the catheter is inserted into the curved region. Therefore, there is a reduced risk that the first core wire and the second core wire will interfere with each other, which would prevent the catheter from bending along the lumen and potentially break one or both of the first core wire and the second core wire.

  • Patent number: 9889044
    Abstract: A steerable laser probe may include a handle, an actuation lever, an optic fiber, and a housing tube. The housing tube may have a first housing tube portion having a first stiffness and a second housing tube portion having a second stiffness. The second stiffness may be greater than the first stiffness. The optic fiber may be disposed within the housing tube and within an inner bore of the handle. An actuation of the actuation lever about a pivot pin of the handle may gradually curve the optic fiber. An actuation of the actuation lever about the pivot pin of the handle may gradually straighten the optic fiber.

  • Patent number: 9889273
    Abstract: Apparatus and methods for an endovascular catheter that can be inserted within tortuous body anatomies and then selectively stiffened and fixed in place. In a particular embodiment, this stiffness is reversible. The stiffness or a comparable mechanical characteristic of the catheter assembly may be adjusted to a relatively low value during insertion (so that it easily navigates a guide wire or the like), and then subsequently adjusted to a relatively high value in situ to keep the catheter assembly substantially fixed in place (i.e., during delivery of an interventional device).

  • Patent number: 9878134
    Abstract: A device having multiple chambers may be configured to expand to contact a substantial section of an interior wall of a body structure or lumen in order to simultaneously exclude blood or other liquid from a target structure while providing for delivery of a therapeutic agent directly to the interior wall. The expandable device may be manufactured from a plurality of flat sheets of material heat sealed to one another to form an inflation chamber and one, two or more delivery chambers. The sheets may also be bonded to an elongate catheter body having inflation and delivery lumens. The excluding of blood flow and delivery of therapeutic agents are completed by the same device.

  • Patent number: 9855048
    Abstract: Systems and methods are provided for reversibly controlling a size and/or restricting the movement of a body orifice, such as a pyloric opening, using an implantable device configured to allow a distance between opposed ends thereof to be adjusted. A device is provided having attachment members and a connector portion extending therebetween and configured such that a size of the pyloric opening is decreased upon the implantation of the device. The connector can be adjustable to allow a size of the pyloric opening to be adjusted after it has been restricted. The connector can include two or more bridge portions having different lengths such that cutting a first bridge portion can increase the distance between the attachment members so as to increase the size of the pyloric opening. To revert to a natural size of the body orifice, the entire connector can be cut or otherwise broken and/or removed.

  • Patent number: 9802025
    Abstract: The present disclosure is directed to an over-the-needle (OTN) catheter assembly having an expandable catheter. More specifically, the OTN catheter assembly includes a catheter having an expandable body with a proximal end and a distal end coaxially mounted onto a needle. The body defines a lumen extending from the proximal end to the distal end. Further, the body is expandable between a compressed length and an expanded length. The needle is configured within the lumen of the catheter and has a first length. The first length is longer than the compressed length of the catheter and shorter than the expanded length of the catheter. In addition, the body of the catheter is configured to expand from the compressed length to the expanded length when heat is applied to the catheter such that the distal end of the catheter extends past a distal end of the needle.
