    Abstract: A medical device includes a mesh member capable of radially expanding and contracting, and a cylindrical member located at one end of the mesh member. The mesh member is woven from a first wire and a second wire. The cylindrical member includes a wrapping portion and a lining portion that are fixed to each other at fixation portions positioned within spaces defined by the first wire and the second wire. Neither the wrapping portion nor the lining portion is fixed to either of the first wire or the second wire. Upon expansion or radial contraction of the mesh member, movement of the first wire or the second wire is not interfered with by the cylindrical member. This reduces the concentration of stress at the end of the mesh member and thus the likelihood that either the first wire or the second wire will break.

  • Patent number: 10856977
    Abstract: A delivery apparatus for a prosthetic heart valve includes a shaft, an inner balloon, and an outer balloon. The shaft has a lumen extending from a proximal end portion to a distal end portion and a plurality of openings formed in the distal end portion. The shaft is configured such that a fluid can flow through the lumen and the openings. The inner balloon has end portions and a center portion disposed between the end portions. The inner balloon is mounted on the distal end portion of the shaft and is in fluid communication with the openings of the shaft. When the inner balloon is inflated with the fluid, the end portions expand farther radially outwardly than the center portion. The outer balloon is mounted to the shaft and disposed over the inner balloon. The outer balloon is configured to fully expand after the inner balloon at least partially expands.

  • Patent number: 10857014
    Abstract: A bifurcated catheter and methods of use are disclosed herein. The bifurcated catheter can include a fixed flat wire that is configurable as a stabilization wire. The bifurcated catheter can be configured to improve the initial access and directability by application of a pull force to the stabilization wire, in addition to a push force from the proximal end of the bifurcated catheter. The stabilization wire is anchored once the bifurcated catheter is positioned. The anchored, bifurcated catheter provides stability and pushability to assist the procedural catheter in traversing the tortuous peripheral vasculature.

  • Patent number: 10851466
    Abstract: The invention relates to a method for grafting an organic film onto an electically conductive or semiconductive surface by electro-reduction of a solution, wherein the solution comprises one diazonium salt and one monomer bearing at least one chain polymerizable functional group. During the electrolyzing process, at least one protocole consisting of an electrical polarization of the surface by applying a variable potential over at least a range of values which are more cathodic that the reduction or peak potential of all diazonium salts in said solution is applied. The invention also relates to an electrically conducting or semiconducting surface obtained by implementing this method. The invention further relates to electrolytic compositions.

  • Patent number: 10835259
    Abstract: An occlusive medical device system may include an elongate shaft having a distal strain relief portion and a lumen extending longitudinally through the elongate shaft, the elongate shaft including a plurality of retaining arms extending distally from the distal strain relief portion; an occlusive medical device including a proximal mounting portion fixed to an expandable occlusive element; and a release wire disposed within the lumen of the elongate shaft. The plurality of retaining arms may extend into the proximal mounting portion. The release wire may be configured to engage the plurality of retaining arms in a distal engagement position, thereby urging the plurality of retaining arms radially outward into releasable engagement with the proximal mounting portion. When the release wire is in a proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal mounting portion.

  • Patent number: 10821271
    Abstract: A balloon catheter for treating a condition of a vessel near a bifurcation comprises a shaft including a proximal and distal end, and a side surface, at least one guide wire lumen extending longitudinally, a distal port extending from the guide wire lumen through the distal end, a side port extending transversely from the guide wire lumen through the side surface, and a balloon mounted on the shaft. The balloon comprises a first end sealed to the shaft proximally of the side port, a second end sealed to the shaft distally of the side port and an aperture aligned with the side port. A portion of the balloon surrounding the aperture is sealed to the shaft around the side port. The balloon may be guided to the bifurcation on a first and a second guide wires pre-positioned in main and in side branch vessel, respectively.

  • Patent number: 10821263
    Abstract: A urinary catheter may include a catheter shaft and a connector coupled with the proximal end of the catheter shaft. The connector may have a first arm ending in a fluid outlet configured to allow urine to flow out of the urinary catheter and a second arm with an aperture and ending in an inflation inlet used for introducing inflation fluid into the urinary catheter. The catheter may further include a primary lumen, an inflation lumen, a retention balloon mounted to the catheter shaft proximal to a fluid inlet and over a distal filling hole, and a pilot balloon mounted on the second arm of the connector over the aperture. The pilot balloon inflates at an inflation pressure that is higher than the inflation pressure of the retention balloon and lower than a predetermined pressure threshold.

  • Patent number: 10799375
    Abstract: An aortic bare stent and an aortic dissection stent are disclosed. The aortic bare stent is in a tubular net structure, with multiple support stents in circles and arranged along an axial direction. Two adjacent support stents are connected by a connector stent. The connector stent is made of a hyper-elastic material. A flexural rigidity of the connector stent is less than that of the support stent. The support stent is made of a single-strand hyper-elastic nickel titanium wire or formed by cutting a nickel titanium tubing. The connector stent is made of a multi-strand composite wire. The multi-strand composite wire is formed by twisting or weaving multiple strands of filaments, and each strand of filament is independently of a nickel titanium material.

  • Patent number: 10779971
    Abstract: A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

    Abstract: Systems and methods and devices are provided for arresting or reversing the effects of myocardial remodeling and degeneration after cardiac injury, without the potential drawbacks associated with previously existing systems and methods, by at least partially occluding flow through the superior vena cava over multiple cardiac cycles, and more preferably, by adjusting the interval or degree of occlusion responsive to a sensed level of patient activity. In some embodiments, a controller is provided that actuates a drive mechanism responsive to a sensed level of patient activity to provide at least partial occlusion of the patient's superior vena cava, while a data transfer circuit of the controller provides bi-directional transfer of physiologic data to the patient's smartphone or tablet to permit display and review of such data.
