Abstract: A medical device is operable to extend and/or retract elements suitable for a particular purpose. The elements are extended and/or retracted in response to a stress applied by way of stretching and/or retracting the device, among other methods. The elements may remain extended and/or retracted or may recoil back to an initial position upon the removal of the force. In various embodiments, the elements are used to treat or deliver treatment to a target site within a body.

Abstract: A medical device comprises a substrate (10) defining a major surface (9) defining a plane, including a plurality of first struts (14) along a first direction interconnected with a plurality of second struts (12) extending along a second direction not parallel with the first direction, wherein widths (11) of the second struts as measured along the major surface are larger than thicknesses of the second struts as measured perpendicular to the major surface such that when the substrate is stretched in the first direction, intermediate sections (15) of the second struts (12) rotate relative to the first struts (14) and the intermediate sections of the second struts bend out of the plane of the major surface. The medical device is operable to extend and/or retract elements suitable for a particular purpose. The elements are extended and/or retracted in response to a stress applied by way of stretching and/or retracting the device, among other methods.

Abstract: Deployment systems and methods are provided herein for percutaneous transcatheter deployment of medical devices. A medical device deployment system includes a body member and a body locking member that is configured to cooperatively engage along a portion of the body member such that the body member is releasably coupleable to a medical device.

Abstract: A thrombus treatment device includes a support wire, a body frame portion that is disposed about an axis defined by the support wire, one or more tethers that each have a first end and a second end, and a filter element extending from the body frame portion. Each of the one or more tethers is attached at its first end to the body frame portion, and at its second end to a collar that couples the second end of each of the multiple tethers to the support wire. When the collar is positioned substantially within a region interior of the body frame portion, a rotational actuation of the support wire causes a swiveling motion of the one or more tethers.

Abstract: A filter cartridge includes a first end component, a second end component, and filter media positioned between the first end component and the second end component is provided. The filter media maintains separation between the first end component and the second end component to allow for air flow through the filter media. The first end component includes at least two receptors and the second end component includes at least one protrusion configured to interface with the at least two receptors to hold the first end component and the second end component in the same relative position with respect to each other when a torque is applied to the filter cartridge. The cartridge is assembled together by adhesive binding the filter media to the first end component and the second end component.

Abstract: Vascular filtering devices and methods for their use are disclosed. In some embodiments, the vascular filtering devices include an elongate member having an unsupported membrane bag portion attached thereto. The membrane may be porous in some examples. Multiple elongate extensions may also extend from the membrane, and may extend along the elongate member, such as to a proximal region of the elongate member. The unsupported membrane bag portion may be configured to inflate or otherwise radially expand away from the elongate member as a result of blood flowing through the vessel within which the vascular filtering device is positioned.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include an access sheath including an elongate body with an internal lumen to facilitate delivery of a device to a target location within a patient. The elongate body may include a distal portion having a distal opening and a plurality of curved segments configured to orient the distal opening relative to the target location.

Abstract: A thrombus treatment device includes a support wire, a body frame portion that is disposed about an axis defined by the support wire, one or more tethers that each have a first end and a second end. Each of the one or more tethers is attached at its first end to the body frame portion, and at its second end to a collar that couples the second end of each of the multiple tethers to the support wire. When the collar is advanced to a position substantially within a region interior of the body frame portion, a rotational actuation of the support wire causes a swiveling motion of the one or more tethers. The swiveling motion of the tethers operates to macerate a thrombus.

Abstract: The instant invention provides for a pivoting ring that can be used as a seal for an inflatable member. The pivoting ring seal offers a mechanical action which acts to tighten with increasing inflation and/or expansion of an inflatable member. As the inflatable member increases in pressure and/or size, one side of the ring is lifted and pivots around a fulcrum in the middle of the ring seal causing the opposite side of the ring seal to decrease in diameter. The pivot ring causes the opposite part of the seal to tighten about an inner member allowing for a higher-pressure seal. In addition to a higher pressure seal, the working length of the inflatable member can be adjusted by moving the ring along the length of the inflatable member.
