A staple cartridge is disclosed. The staple cartridge can include a cartridge body, a plurality of staples, and an implantable layer. The implantable layer can include a piece of lyophilized foam and a plurality of fibers at least partially embedded in the piece of lyophilized foam. The implantable layer can further include a plurality of pores defined in piece of lyophilized foam, and a plurality of pockets, wherein a pocket at least partially surrounds a fiber. A method of forming an implantable layer for use with a surgical staple is also disclosed. The method can comprise obtaining a mold comprising a cavity, placing a plurality of fibers in the cavity of the mold, dispensing a solution into the cavity around the fibers, and lyophilizing the solution in the cavity.

An incrementally adjustable wound retractor (500), having a first ring (504) with a diameter greater than the desired diameter of the wound incision, a flexible second ring (502), having a lumen and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve (506), disposed in a generally cylindrical form between the first and second rings (502, 504), where the second ring may be rolled over itself to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.

A device for treating the lumen of a living body includes a shaft insertable into a blood vessel, and a balloon provided on the shaft and shiftable between a deflated state and an expanded state. In the expanded state, the balloon has a recessed portion configured to form a coating chamber which is substantially blocked between an inner surface of the blood vessels and the device for treating the lumen of a living body, a discharge port provided on the recessed portion to discharge a coating substance toward the coating chamber; and a suction port provided on the recessed portion to apply a negative pressure to the coating chamber.

A tissue thickness compensator can comprise a compensator body and at least one vessel contained in the compensator body. The vessel can define an inner cavity which can comprise an inner atmosphere having a pressure which is lower than the atmospheric pressure of the atmosphere surrounding the tissue thickness compensator. In at least one embodiment, the vessel and the compensator body can be maintained in a collapsed state until staples are fired through the vessel. At such point, the vessel can re-expand and apply a biasing force to tissue captured within the staples.

An incrementally adjustable wound retractor (100), having a first ring (102) with a diameter greater than the desired diameter of the wound incision. A second ring (104), having an annular axis and a diameter greater than the desired diameter of the wound incision. A flexible sleeve (106), disposed in a generally cylindrical form between the first and second rings (102, 104), the second ring may be rolled over itself and around the annular axis to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.
摘要:
The devices and methods shown provide for the minimization of extravasation during arthroscopic surgery. The extravasation minimization device allows a surgeon to drain excess fluids from the soft tissue surrounding the surgical field while also providing a stable surgical portal for arthroscopic surgical instruments.
摘要:
A self-expanding medical occlusion device treats a heart defect in a patient and is erted into the body in minimally invasive fashion using a catheter system, and includes raiding of thin threads which exhibits a first preliminarily definable shape as the clusion device is being inserted into the patient's body and a second preliminarily finable shape in the implanted state, whereby the occlusion device is in a collapsed te in the first shape of the braiding and in an expanded state in the second shape of braiding. The threads of braiding are composed of a shape memory polymer mposite such that braiding deforms from a temporary shape to a permanent shape in nsequence of an external stimulus, whereby the temporary shape is given in a first ofile form of the braiding and the permanent shape is given in a second profile form of braiding.
