International Classification:

A61B 17/28

US Classification:

606206

Abstract:

An articulating laparoscopic instrument including a handle body, a shaft, an end effector, an operation mechanism, and an articulation mechanism. The end effector is connected to a shaft end. The operation mechanism includes a rod and an actuator. The rod is coupled to the end effector. Movement of the actuator relative to the handle body transfers a force onto the rod in a longitudinal direction to operate the end effector. The articulation mechanism includes a deflection assembly, first and second collar assemblies, first and second cables, a linkage, and an articulation actuator. The first and second collar assemblies are slidably disposed over the rod. The cables extend between the collar assemblies and the deflection assembly. Movement of the articulation actuator drives the first and second collar assemblies in opposite directions to cause a longitudinal deflection in the deflection assembly.

Abstract:

A suture passer device includes a shaft, a handle, an end effector, and a suture capturing member. The shaft has a shaft proximal end and a shaft distal end. The handle assembly is coupled to the shaft proximal end. The end effector is coupled to the shaft distal end. The suture capturing member is coaxial with and slideably coupled to the end effector, is coupled to the handle assembly, and is configured to capture a suture within the end effector. A suture needle includes a suture needle body and a suture needle tip, the suture needle body having a first portion and a second portion. The first portion is thicker than the second portion, and the first portion is configured to mate with a needle spacer that enables actuation of a suture needle passer device.

US Classification:

604506, 604221, 53440

Abstract:

A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands.

International Classification:

B43K 8/04

US Classification:

401143, 401206

Abstract:

A micro motion poppet valve for a writing instrument provides delivery of ink with large pigment particles to a porous writing nib with minimal nib movement and relatively light actuation forces. The micro motion poppet valve includes a nib connected to a valve stem, the valve stem being connected to a valve plug. A valve body is integrally formed with a biasing element, which biases the valve stem towards a closed position. When a user presses the nib against a writing surface the valve plug moves away from a raised valve seat located on the biasing element to allow ink to flow from an ink reservoir to the nib.

International Classification:

A47G 9/10

Abstract:

A plurality of inflatable pillows. Each pillow has at least one chamber. The chamber defines first and second edges oppositely disposed. Each pillow also has a valve providing fluid communication with the chamber for inflating and deflating the chamber. The first edge of one pillow is connect to a second edge of another pillow to form a continuous web. The pillows may form a continuous web and be dispensed from a device. Separation of the pillows one from another is enabled by perforations between edges of the pillows forming the web or tearing or cutting between edges of the pillows forming the web.
