International Classification:

A61B 1710

US Classification:

606144, 606139, 606148

Abstract:

The present invention provides devices and methods for suturing a tissue layer having two sides with a suture by releasably retaining at least a portion of the suture in a stationary position on one side of the tissue layer. The portion of the suture is retrieved through the tissue layer from the opposite side whereby the suture is drawn from one side to the opposite side. Devices and methods for suturing the wall of a tubular graft having two sides is also provided using a suture by releasably retaining at least a portion of the suture on one side of the wall. The portion of the length of suture is retrieved through the wall of the graft to the opposite side of the wall. A graft anastomosis assembly provided herein sutures a tubular graft about an aperture in a tissue wall using a suture, a tissue suturing and graft suturing devices. Fastener types other than sutures are useful with the present invention whereby a first fastener portion is releasably retained in a stationary position on one side of a tissue layer while a second fastener portion is driven through the tissue layer from the opposite side and securely engages the two portions together.

International Classification:

A61B017/12

US Classification:

606144, 606139, 606148

Abstract:

Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.

Abstract:

A flow control device includes a sealing component that can be positioned within a bronchial lumen. The sealing component can comprise two or more overlapping segments that are movable relative to one another such that the segments collectively form a seal that can expand and contract in size to fit within and seal bronchial lumens of various sizes.

US Classification:

12820714, 12820227

Abstract:

Disclosed is an anesthesia adapter that is suitable for the simultaneous insertion of multiple devices or instruments into the lungs during ventilation of the patient, while minimizing or eliminating gas leaks. The anesthesia adapter comprises in one embodiment a first port sized to receive a first elongate instrument; a second port sized to receive a second elongate instrument; an endotrachial tube fitting configured to be coupled to an endotrachial tube, the endotrachial tube fitting fluidly coupled to the first and second ports; and a hose fitting configured to be coupled to a ventilator hose, the hose fitting fluidly coupled to the first and second ports. The first port seals around the first elongated instrument and the second port seals around the second elongate instrument.

Abstract:

Comparative genomic hybridization assays and compositions for use in practicing the same are provided. In the subject methods, at least first and second genomic templates are prepared from first and second genomic sources using an amplification reaction that employs a highly processive polymerase, where the amplification reaction produces amplification products having an average molecular size of at least about 10 kb with substantially no amplification bias. The resultant templates are then employed to produce at least first and second probe nucleic acid populations. The resultant probe nucleic acid populations are then contacted with a plurality of oligonucleotide target elements immobilized on a solid support surface and the binding of at least first and second populations is then evaluated. Also provided are kits for use in practicing the subject methods.
