  • Patent number: 11357484
    Abstract: An improved assembly for securing an implantable medical device for retrieval from an implant site includes a plurality of snares, wherein distal openings of a first snare carrier lumen and a second snare carrier lumen have a pre-set offset established therebetween. First and second snare shafts, to which first and second snare loops are coupled, respectively, extend within the corresponding snare carrier lumens such that each loop is located in proximity to the corresponding distal opening of the lumen. The pre-set offset allows an operator to simultaneously position the snare loops around the device; and, when the operator retracts the snare shafts to collapse the snare loops until the loops fit snuggly around the device, the pre-set offset can help to align the device for retrieval.

  • Patent number: 11357540
    Abstract: A port fixation device is disclosed and includes a body portion and a plug. The body portion includes a circular portion, a first tab, and a second tab. The circular portion defines an aperture which is configured to allow a surgical access port to extend therethrough. The first tab and the second tab are disposed in mechanical cooperation with the circular portion. Movement of the first tab with respect to the second tab from a first position to a second position causes a diameter of the aperture to change from a first size to a second size. The first size is smaller than the second size, and the first position of the first tab is its rest position. The plug is disposed in mechanical engagement with the body portion, and has sufficient elasticity to remain engaged with the body portion when the first tab is in the first position and in the second position.

A delivery system can include an implant with a proximal portion that defines a port. A pusher device can include arms extending distally from a junction of the pusher device and through the port, with distal sections of the arms disposed within the implant. The arms can, at a certain temperature, transition from engagement with the implant to a shape that facilitates release of the implant. Additionally or alternatively, a coil can engage an outer surface of the implant at the proximal portion and transition to a shape that facilitates release of the implant.

  • Patent number: 11039735
    Abstract: A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery is made of a braid material. The sheath may be manufactured by placing a length of braided tube material over a mandrel. The braid material is conformed to the shape of the mandrel and is then heat set. An atraumatic end may be made by folding or rolling one or both ends of the sheath. A coating may also optionally be applied to the braid material. The sheath reduces collateral trauma to the tissues in the surgical pathway.

  • Patent number: 10993807
    Abstract: A catheter-based system for percutaneously supporting and articulating a septal wall of a heart includes a catheter and a flanged device. The flanged device includes a distal anchor and a proximal anchor, and has a radially collapsed configuration and a radially expanded configuration. When the flanged device is in the radially expanded configuration and disposed through a transseptal puncture in the septal wall, the flanged device is configured to anchor to the septal wall to permit manipulation thereof whereby an angle between an axis through the transseptal puncture and an axis through a native valve is reduced. The proximal anchor and the distal anchor may each be self-expanding or balloon expandable. The flanged device may further include a flanged device shaft. The flanged device shaft may be releasably coupled to the catheter.

  • Patent number: 10973667
    Abstract: Apparatus and method for delivering and deploying an intravascular device into the vessel including an outer and inner tube that are axially linked by a housing structure at the proximal end of the catheter, and a retractable sleeve structure having a middle tube and sleeve tip. The sleeve tip is sealed to the inner tube at the distal end, and continuously extends into the middle tube. At the proximal end of the sleeve structure, the middle tube is sealed to either a housing structure or slideable proximal ring, forming a sealed chamber between the inner tube and the sleeve structure. A radial space is formed between the sleeve tip and the inner tube optimized for intravascular device placement. During retraction of the sleeve structure, the fold of the sleeve tip peels away from the device, which expands to its deployed state while minimizing axial forces and friction.

  • Patent number: 10973663
    Abstract: Distal tips for use with delivery catheters are disclosed that are configured to maintain complete engagement between the distal tip and a distal opening of a sheath component of the delivery catheter so as to prevent separation therebetween and/or to prevent fish-mouthing of a distal leading edge of the sheath component during in vivo use. Distal tips so configured realize one or more of the objectives of safer tracking of the delivery catheter through the vasculature, safe crossing of the delivery catheter through structural components of the vasculature and heart, such as through native valves, and safe removal of the delivery catheter post deployment.
