  • Patent number: 11974755
    Abstract: An occlusive implant with a backbone support structure can be delivered into a body vessel using a delivery assembly that can engage with at least a portion of the implant. The assembly can utilize an engagement member and an engagement socket or a catheter or sheath to removably couple the engagement member with the implant. When the implant is advanced to a target location in the body vessel, the implant can be released to restrict flow of a fluid through the vessel and/or promote occlusion of the vessel.

  • Patent number: 11224438
    Abstract: A method of implanting an occlusive device in a perforator vessel may include introducing a needle through skin of a patient, and advancing the needle into a perforator vessel, the perforator vessel extending between a superficial vein and a deep vein. The method may further include distally advancing a delivery component from within the needle until a distal end of the delivery component extends into the deep vein and releasing a distal portion of the occlusive device into the deep vein. The needle may then be proximally withdrawn from the perforator vessel such that the device is exposed within the vessel, and the proximal portion of the device may be released into the superficial vein such that the device blocks flow through the vessel.

  • Patent number: 10441290
    Abstract: An implant may include a frame and a cover to facilitate endoluminal vessel occlusion, selective release of embolic material toward a target region, and/or endoluminal stenting. The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel.

  • Patent number: 10363043
    Abstract: An implant device can include a frame and a cover member for delivery to and occlusion of a target body vessel. The frame can include proximal and distal members, coupled by a link member structure, and can expand from a collapsed configuration to an expanded configuration. In the collapsed configuration, a first plane passes through the proximal member and a second plane passes through the distal member, and the link member extends substantially parallel relative to a longitudinal axis of the device. In moving to the expanded configuration, the first and second planes each move angularly, relative to the longitudinal axis, from the collapsed configuration by between about 10 degrees and about 170 degrees, and the link member foreshortens along the longitudinal axis to bias the proximal member toward the distal member.

  • Patent number: 10149968
    Abstract: A method for treating a subject diagnosed with a cancer or other disorder comprising a hyperproliferative tissue is described herein. The method includes localized delivery of a material which contains a therapeutically effective agent and/or moiety. The localized delivery of the agent is achieved using a catheter-based delivery system and an implant. An implant can include a support component, a cover component, and a valve component. The valve component can be operable to permit flow through the implant. The implant can be delivered on a catheter, with one of the ends of the implant being selectively expanded to permit temporary occlusion of a vessel while delivering a material through the valve component to a downstream target region. The other end of the implant can thereafter be released such that the implant occludes the vessel, or the implant can be removed from the vessel entirely.

  • 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: 9737307
    Abstract: An occlusion device delivery system can deliver an implant using a catheter. A distal section of the catheter has proximal and distal apertures extending through a wall of the catheter. The implant can be wound about the distal section and secured to the catheter via an engagement mechanism. The implant has a proximal segment that curves inwardly across the proximal aperture and a distal segment that curves inwardly across the distal aperture. The engagement mechanism engages the proximal and distal segments within their respective apertures to secure the implant to the catheter.

  • Patent number: 9451965
    Abstract: A method for reducing or stopping flow through a tubular structure of a patient can include positioning an elongate member within a lumen of the tubular structure. The elongate member can be arranged to form a frame having a distal opening and a proximal opening. The elongate member can substantially reduce or totally obstruct, with a flow reducing member coupled to the frame, flow of at least one of emboli and fluid flowing through the lumen. The flow reducing member can comprise a one-way valve that moves in response to fluid flow to substantially prevent distal flow through the distal opening and to allow proximal flow through the distal opening.

  • Patent number: 9247942
    Abstract: Described are apparatus and methods for preventing sperm passage through a reproductive structure of a patient, and also for subsequently reversing the preventative measure in order to restore fertility to the patient. In some embodiments, the apparatus includes an elongate member arranged to form a frame having a distal and proximal opening and configured to be positioned within a lumen of the reproductive structure. The apparatus may also have a flow reducing member coupled to the frame such that when the frame is positioned within the lumen, the flow reducing member substantially impedes, reduces, or totally obstructs passage of sperm through the lumen.

  • Patent number: 9149277
    Abstract: A device for delivering an expandable member to a luminal structure in a patient is described. In some embodiments, the device has a carrier member, with a carrier lumen extending at least partially therethrough. The device can have an elongate member that extends through the carrier lumen across a first notch in the carrier member. The device can have an expandable member that expands within and engages the luminal structure, can be carried by the carrier member, and has a first portion that fits within the first notch. When the elongate member extends through the carrier lumen and across the first notch, the elongate member secures the first portion to the carrier member. The elongate member is configured to move axially through the carrier lumen such that the elongate member permits release of the first portion from the carrier member and expansion of at least part of the expandable member.

  • Patent number: 9017351
    Abstract: In some embodiments, an apparatus, for reducing or stopping flow through a tubular structure of a patient, includes an elongate member arranged to form a frame having a distal and proximal opening and configured to be positioned within a lumen of the tubular structure. The frame includes a proximal, distal, and middle portion. The distal portion is tapered such that an outer cross sectional dimension (OCSD) of the distal opening is less than an OCSD of the middle portion. The frame is configured to be inverted such that the distal portion moves within and toward the middle portion for removing the frame from within the lumen. The apparatus also comprises a flow reducing member coupled to the frame such that when the frame is positioned within the lumen, the flow reducing member substantially reduces or totally obstructs flow of at least one of emboli and fluid flowing through the lumen.
