International Classification:

A61B 500

US Classification:

600567

Abstract:

A device for encapsulating tissue specimens includes a wand assembly, a sheath, and a guide assembly. The guide assembly pulls, draws, or otherwise moves the sheath about the tissue specimen. The wand assembly is disposed proximate to the tissue specimen, typically either adjacent or through the specimen. In an aspect of the encapsulating device, the guide assembly has sheath deployment members that are disposed about the tissue specimen. The sheath, which is attached to ends of the sheath deployment members and the wand assembly, is drawn over the tissue specimen as the sheath deployment members are pushed or pulled. In another aspect of the device, the guide assembly is an arm or a housing that rotates about the tissue specimen. The sheath, which is secured at one end to the guide assembly and at another end to the wand assembly, is drawn over the tissue specimen as the guide assembly rotates. The sheath may be made up of porous material, non-porous material, selectively permeable material, woven material, braided material, knit material, web material, mesh material, a film material, a flexible laminate material, or of an elastic material.

International Classification:

A61B 17/221

Abstract:

Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. In one embodiment, a funnel catheter assembly includes an outer shaft and an inner shaft extending through and coaxial with the outer shaft. An expandable funnel can be coupled to a distal portion of the inner shaft. The funnel catheter assembly further includes a control assembly operably coupled to the proximal portion of the outer shaft and configured to move the outer shaft between a first position and a second position. In the first position, the outer shaft is positioned at least partially over the funnel to constrain the funnel in a compressed state. In the second position, the outer shaft is retracted proximally relative to the funnel such that the funnel can expand to an expanded state.

Abstract:

Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include: providing a thrombus extraction device including a proximal self-expanding member formed of a fenestrated structure, a substantially cylindrical portion formed of a net-like filament mesh structure having a proximal end coupled to a distal end of the fenestrated structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction device by stacking a portion of the net-like filament mesh structure outside of the catheter by distally advancing the self-expanding member until the self-expanding member is beyond a distal end of the catheter; retracting the self-expanding member to unstack the portion of the net-like filament mesh structure and to capture the portion of the thrombus; and withdrawing the thrombus extraction device from the body.

Abstract:

Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include: providing a thrombus extraction device including a proximal self-expanding member formed of a unitary fenestrated structure, a distal substantially cylindrical portion formed of a net-like filament mesh structure, and an inner shaft member connected to a distal end of the net-like filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction; retracting the thrombus extraction device to separate a portion of the thrombus from the vessel wall and to capture the portion of the thrombus within the net-like filament mesh structure; and withdrawing the thrombus extraction device from the body to remove thrombus from the patient.
