Percutaneous access systems, including trocars, for accessing desired locations within a subject's body through the subject's skin or other tissues that are configured to minimize incision sizes are disclosed. Such a percutaneous access system includes a cannula and an obturator. The cannula includes a passageway with a tapered section and an expandable section at its distal end. The expandable section may include leaves that are configured to extend radially outward as an elongated instrument that has an outer diameter that exceeds a minimum relaxed inner diameter of the tapered section of the passageway is forced through the tapered section. Methods for using such a percutaneous access system, including medical procedures, are also disclosed.

The present invention includes a surgical stapler having a staple cartridge, an anvil, and a cutting member having a cutting surface, wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In at least one embodiment, the anvil is movable between an open position and a partially-closed position. When the anvil is in its partially-closed position, the anvil and the staple cartridge can be configured to capture tissue therebetween without fully compressing the tissue. In at least one embodiment, the anvil includes a proximal portion, a distal portion, and a middle portion intermediate the proximal portion and the distal portion. In these embodiments, the tissue can be captured between the proximal and distal portions of the anvil before the middle portion of the anvil is brought into contact with the tissue.

A system for implanting a penile prosthetic (21) into a penis includes a penile implant, a tow suture (24), a delivery cap (25), and an insertion tool (20). The implant has a proximal end (22) insertable into a crus penis and a distal end (23) insertable into a glans penis. The tow suture is removably secured to the distal end of the penile implant. The delivery cap is coupled to the tow suture. The insertion tool has a distal tool end insertable into a corpora cavernosum of the penis and includes a needle (30) configured for delivery through the glans penis. The delivery cap has an aperture (112), with a portion of the tow suture located in the aperture.

The present invention includes a surgical stapler having a curved end-effector which is configured to deploy staples in at least one curved staple line. In various embodiments, the surgical stapler includes a staple cartridge, an anvil, and a cutting member having a cutting surface wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In one embodiment, the staple cartridge can be configured to deploy staples along different, non-parallel axes. As a result, the staples can be deployed in a significantly curved staple line. In various embodiments, the surgical stapler includes a flexible driver operably engaged with the cutting member to move the cutting member relative to the anvil and the staple cartridge. In these embodiments, the driver can include an elongate cross-section defined by a width and a height wherein its width is greater, and in some cases, substantially greater, than its height.
