  • Publication number: 20200113687
    Abstract: An apparatus for partially supporting a leaflet of a regurgitant heart valve comprises at least one subvalvular device including a subvalvular supporting portion including a leaflet-contacting upper supporter surface longitudinally spaced from an oppositely facing lower supporter surface. A supporter perimeter wall extends longitudinally between the upper and lower supporter surfaces, with at least a portion contacting a subvalvular cardiac wall adjacent to the heart valve. An anchor portion is adjacent to, and longitudinally spaced from, the upper supporter surface. The anchor portion includes a leaflet-contacting lower anchor surface longitudinally spaced from an oppositely facing upper anchor surface. A connector neck is interposed longitudinally between, and is directly attached to both of, the upper supporter surface and the lower anchor surface. The connector neck penetrates longitudinally through at least one of a base of the leaflet and an annulus of the heart valve at a manufactured puncture site.

  • Publication number: 20190142495
    Abstract: A cryo-fixation lead extraction device includes a lead extraction catheter having longitudinally spaced proximal and distal catheter ends and an elongate catheter lumen. A liner has longitudinally spaced proximal and distal liner ends and an elongate liner lumen. The liner lumen is configured to selectively accept at least part of a lead being extracted longitudinally therethrough. At least a portion of the liner is located circumferentially within and/or circumferentially surrounding the catheter lumen. At least one cryogen supply line extends longitudinally through at least a portion of the liner lumen. The cryogen supply line is configured to place a cryogen fluid source into fluid communication with the distal liner end. The cryogen supply line is configured to selectively generate a patient tissue cooled zone adjacent the distal catheter end. A method of cryo-fixation lead extraction is also provided.

  • Patent number: 10098724
    Abstract: Catheters, assemblies, and methods for delivering and recovering embolic protection devices. Catheters are provided that can be advanced over single length guide wires and which can be retracted over single length wire shafts of distal embolic protection devices. One catheter is a two-port catheter having two sidewall ports, a distal end port, and a proximal end port. The two-port catheter can be advanced over a guide wire threaded between the distal end port and the distal sidewall port. An embolic protection device wire shaft can be back loaded into the distal end port and out the proximal sidewall port. A three-port catheter includes a distal end port, and distal, intermediate, and proximal sidewall ports. The distal sidewall port can be dimensioned to accept passage of a filter body through the port. The distal end port can be dimensioned to accept only a guide wire to provide a smooth transition from the guide wire to the small profile distal end.

  • Publication number: 20180221128
    Abstract: Systems, methods, and apparatuses for collecting emboli include an embolic dual-filtration device are disclosed. The embolic dual-filtration device has a first filter and a second filter. The first and second filters have pores. The second filter is positioned adjacent to the first filter. The first and second filters are capable of being selectively rotated with respect to one another. The first and second filter pores of the rotated first and second filters collectively form a moiré lattice structure. The moiré lattice structure has pores smaller than the pores of each of the separate first and second filters.

  • Patent number: 9770256
    Abstract: A medical device for safely and effectively removing a clip or a suture from a heart valve is operable in association with a guidewire for positioning the device in proximity to the heart valve. The apparatus may include a blade for cutting a tissue bridge including the clip and an arrangement for removing the tissue bridge from the heart valve. The apparatus may include two arms that secure the clip. The blade may be deployed to core out a central portion of a tissue bridge, including the clip or the suture, from the heart valve. The blade may be activated by an actuator. A retrieval member may be configured to capture the tissue bridge and the clip or suture after excision by the blade.

  • Patent number: 9498585
    Abstract: An apparatus for targeting a desired target site on a body tissue comprising a wall of a first body cavity of a patient includes a target catheter. The framing member, when deployed into an expanded condition, has a framing member body which includes a three-dimensionally bulbous portion defining a maximum body footprint in a lateral dimension and has longitudinally spaced proximal and distal body ends which are both longitudinally spaced from the maximum body footprint. The proximal body end is attached to the target catheter. A protrusion has a diameter which is smaller than the maximum body footprint diameter. At least one target point is carried by the framing member and is adapted for placement adjacent the desired target site. At least one target pathway is attached to at least one target point. At least a portion of the target pathway is substantially spaced apart from the framing member body.

  • Patent number: 9492623
    Abstract: An apparatus for targeting a desired target site on a body tissue comprising a wall of a first body cavity of a patient includes a target catheter. A framing member has a collapsed condition and an expanded condition. The framing member has a framing member body which includes a bulbous portion defining a maximum body footprint having proximal and distal body ends which are both longitudinally spaced from the maximum body footprint. The framing member is comprised of a plurality of framing member beams. At least three framing member beam arrays of framing member beams are arranged in non-overlapping longitudinal sequence to form at least a portion of the framing member. The framing member beams that make up the framing member substantially each have a width-to-thickness fractional ratio in the range of 0.6-3.0.

  • Patent number: 9468514
    Abstract: Everting filter devices and methods for using the devices, including using the devices as intra-vascular filters to filter thrombus, emboli, and plaque fragments from blood vessels. The filter devices include a filter body nominally tubular in shape and having a large proximal opening. The filter body can extend from a proximal first end region distally over the non-everted exterior surface of the filter, further extending distally to a distal-most region, then converging inwardly and extending proximally toward the filter second end region, forming a distal everted cavity. The degree of eversion of the filter can be controlled by varying the distance between the filter first end region near the proximal opening and the closed second end region. Bringing the filter first and second end regions closer together can bring filter material previously on the non-everted filter exterior to occupy the distal-most region.
