Patent application numberDescriptionPublished
20080262472Catheter With Reinforcing Layer Having Variable Strand Construction - A catheter includes an elongate member having a braided reinforcing layer encased within a polymeric bonding layer. The reinforcing layer comprises a plurality of continuous filaments that transform from a full complement braid configuration to a partial complement braid configuration in a least one location along the catheter. Also disclosed is a method of manufacturing a braided elongate member including providing a core, forming at least one full complement braid portion with a plurality of filaments and forming at least one partial complement braid portion with a portion of the same plurality of filaments.10-23-2008
20090240206Rapid Exchange Catheter With Tear Resistant Guidewire Shaft - A rapid exchange-type catheter for aspiration of embolic debris from a blood vessel includes an elongate aspiration tube and a relatively short guidewire tube mounted beside a distalmost portion of the aspiration tube. A proximal portion of the guidewire tube defines a strain relief segment. In one embodiment, the strain relief segment is formed detached from the aspiration tube. In another embodiment, the strain relief segment is minimally attached to the aspiration tube and becomes detached from the aspiration tube when a sufficient transverse force is applied to urge the guidewire tube away from the aspiration tube.09-24-2009
20090270839Braided Catheter Reinforcement Layer Having Short Axial Filament Segments - A catheter includes an elongate member having a braided reinforcing layer. The reinforcing layer comprises a plurality of continuous filaments that transform from a braided configuration to short axially oriented segments in a least one location along the catheter. Also disclosed is a method of manufacturing a braided elongate member including providing a core, forming at least one braided portion with a plurality of filaments and forming at least one short axially oriented segment with at least a portion of the same plurality of filaments.10-29-2009

20090112270Anchor Assembly - The present disclosure relates to an anchor assembly. The anchor assembly includes an anchor defining a cavity and an opening to the cavity and an insertion member configured for arrangement within the anchor cavity. The insertion member includes a body having a proximal end portion and a flat distal end portion, and a head coupled to the proximal end portion of the body. A method of tissue repair and other anchor assemblies are also disclosed.04-30-2009
20100016869Surgical Devices - The present disclosure relates to a surgical device including a shaft having an outer member and an inner member slidably received within the outer member, a handle coupled to the shaft, and a means for providing movement to the inner member coupled to the inner member. A method of tissue repair is also disclosed.01-21-2010
20100152773Composite Anchor - The present disclosure relates to a composite anchor. The anchor includes a cannulated proximal portion having a threaded outer surface and a distal portion coupled to the proximal portion, the distal portion including a top portion, a bottom portion, and a through hole, wherein the top portion is configured to be disposed within the cannulation of the proximal portion.06-17-2010

20080294123Seal Assembly For A Cannula - The present disclosure relates to a seal assembly for a cannula. The cannula includes a housing having a proximal portion and a distal portion. The seal assembly is located in the proximal portion of the housing and includes a first seal including a first tri-slit, a second seal disposed co-axially and proximal to the first seal and including a second tri-slit, and a third seal disposed co-axially to the first seal and the second seal and including a central opening. A cap is coupled to the proximal portion of the housing and adjacent the third seal and includes a plurality of suture retaining features, such as tabs, for management of sutures during surgery. Fluid leakage out of the cannula, during surgery, is substantially reduced due to the leakage being limited to a channel defined by the first tri-slit, the second tri-slit, and the central opening.11-27-2008
20100016902Anchor - The present disclosure relates to an anchor. The anchor includes an outer member including a body having an inner cavity, wherein the inner cavity includes a proximal portion configured for receipt of a delivery device and a distal portion having area of increased diameter. The anchor also includes an inner member coupled to the outer member, wherein the inner member includes a proximal portion having a projection configured for receipt in the area of increased diameter and a distal portion having a transverse through hole. A delivery device and method for tissue repair are also disclosed.01-21-2010
20100069958Tenodesis Implant - The present disclosure relates to a two-piece implant. The implant includes a first piece having at least two prongs and a protrusion located between the prongs and a second piece coupled to the first piece, wherein the second piece is configured to rotate relative to the first piece. A method of tissue repair is also disclosed.03-18-2010
