Patent number: 9636101Abstract: The present disclosure includes a knotless suture anchoring system for anchoring a suture with respect to a body cavity, including a bone anchor body with at least one rigid anchoring structure to secure the anchor body within the body cavity. The anchor body has a longitudinal bore and cross-pin extending across the bore. A retention member is coupled to the anchor body with a break notch therebetween, which may selectively fracture to separate the body from the retention member. Additionally there is a suture cutout on the retention member and a relief feature positioned along the break notch and approximately diametrically opposed from the suture cutout, the relief feature acting to alter the force dissipation along the break notch during the separation of the retention member from the anchor body.Type: GrantFiled: September 4, 2012Date of Patent: May 2, 2017Assignee: ArthroCare CorporationInventors: Steven Wolf, Vincent Tangherlini, Norman S.

Patent number: 9622740Abstract: A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (Tload) to the tensioning suture limb.Type: GrantFiled: March 5, 2015Date of Patent: April 18, 2017Assignee: Cayenne Medical, Inc.Inventors: Kevin S.

Patent number: 9585666Abstract: A nerve guidance conduit includes a spiral structured porous sheet decorated with channels on its surface and electrospun nanofibers in a parallel alignment with the channels and an outer tubular structure including randomly-oriented nanofibers. Such a structure provides augmented surface areas for providing directional guidance and augmented surfaces for enhancing and peripheral nerve regeneration. The structure also has the mechanical and nutrient transport requirements required over long regeneration periods. To prepare a nerve guidance conduit, porous polymer sheet is prepared by a solvent casting method while using a template of thin rods to form parallel channels on a surface of the sheet. Aligned nanofibers are deposited on the sheet parallel to the channels. The polymer sheet is then wound to form a spiral structure. A dense layer of randomly-oriented nanofibers may be deposited on the outside of the spiral.Type: GrantFiled: June 24, 2014Date of Patent: March 7, 2017Assignee: THE STEVENS INSTITUTE OF TECHNOLOGYInventors: Xiaojun Yu, Wei Chang

Patent number: 9498202Abstract: Disclosed herein are exemplary embodiments of suture securement devices that replace the need to tie knots in sutures. Some embodiments comprise an annular outer body and one or more suture engagement tabs extending inwardly from the outer body. The devices can comprise a superelastic and/or shape-memory material and have a generally in-plane initial configuration. The suture engagement portions are deformable out-of-plane to an active configuration with the outer body compressed and the tabs interlocked with each other. The device can be heat-set in the deformed configuration. The interlocked tabs exert a pinching force on sutures passing between them that restricts the sutures from sliding through the opening in one longitudinal direction.Type: GrantFiled: July 9, 2013Date of Patent: November 22, 2016Assignee: Edwards Lifesciences CorporationInventors: Mohammad Jafari, Ming H. Wu, Hengchu Cao, Ralph Schneider, Manouchehr A. Miraki

Patent number: 9486126Abstract: An endoscopic tissue grasper device includes a flexible tubular member, a flexible shaft extending through the tubular member, a proximal handle for moving the shaft and tubular member relative to each other, and a distal helical coil having a sharpened end for engaging tissue. The helical coil has a proximal close wound portion, a distal open wound portion, and an intermediate transition portion between the proximal and distal portions. The flexible shaft extends into the proximal and intermediate portions and is secured thereto, which prevents tissue engaged by the helical coil from becoming wedged in the transition portion and thereby facilitates release of the coil from engaged tissue. In addition, a bearing sheath is provided between the shaft and tubular member to prevent the shaft from binding during operation.Type: GrantFiled: July 2, 2012Date of Patent: November 8, 2016Assignee: Apollo Endosurgery, Inc.Inventors: Stephen West, David Miller, Vladimir Mitelberg, Donald K.

Patent number: 9393153Abstract: Intraocular pressure can be reduced by insertion of an intraocular shunt in the eye such that it forms a drainage pathway between the anterior chamber and a region of lower pressure. A hollow shaft can be advanced through the anterior chamber with the hollow shaft (a) having a beveled tip at a distal end of the hollow shaft and (b) holding an intraocular shunt with a proximal end of the shunt within the hollow shaft. The sclera can be penetrated with the hollow shaft. A beveled surface of the beveled tip can be oriented such that the beveled surface faces toward the Tenon's capsule when the beveled tip passes out of the sclera. After the beveled tip passes out of the sclera, at least a portion of the shunt can be advanced from the hollow shaft.Type: GrantFiled: September 3, 2014Date of Patent: July 19, 2016Assignee: AqueSys, Inc.Inventors: Christopher Horvath, Laszlo O.
