A trocar assembly includes a trocar housing that defines a working chamber, and a cannula having a proximal end and a distal end, wherein the cannula is coupled to the trocar housing at the proximal end to facilitate communication between the cannula and the working chamber. A plurality of radial support members are arranged at or near the distal end and comprise a plurality of keystones arranged side by side to form a ring within the cannula. Each radial support member extends radially inward toward a centerline of the cannula to center a surgical tool within the cannula and thereby minimize unintended oscillation and vibration of the surgical tool.

A surgical port includes a shell and a seal assembly. The shell has a housing and a cannula that extends from the housing. The housing has a sidewall defining a window therethrough. The seal assembly includes one or more seals. The seal assembly is selectively receivable into the housing through the window of the housing of the shell.

A suture cleating system for arthroscopic or endoscopic cannula to facilitate suture management while preserving seal functionality. The suture cleating system includes an end cap with an aperture extending therethrough and one or more cleats extending therefrom. A cannula body extends distally from the end cap. A seal is connected between the cannula body and the end cap. The seal has a seal slit extending therethrough and the seal slit is substantially aligned with the aperture of the end cap. In use, a suture extends through the cannula, the seal slit, and the aperture in the end cap. The suture can be tensioned from the aperture in the end cap and secured in a suture slot between two cleats.

A wound retractor includes a sleeve with proximal and distal ends, an inner ring inside the sleeve between the proximal and distal ends, and an outer ring outside the sleeve between the proximal and distal ends. The inner ring includes a tapered outer surface that increases in diameter from a proximal end of the inner ring toward a distal end of the inner ring. The outer ring includes a tapered inner surface that increases in diameter from a proximal end of the outer ring toward a distal end of the outer ring. A portion of the sleeve is captured between the tapered outer surface and the tapered inner surface.

A medical device includes a medical instrument guide. The medical instrument guide includes a guide body, The guide body includes a foam and a bore through the foam. The foam includes a plurality of open cells that hold a biocompatible lubricant. And, the bore is sized to receive a medical instrument shaft and is defined at least in part by a surface exposing the plurality of open cells holding the biocompatible lubricant to the medical instrument shaft.

A method of removing embolic material from a vessel with mechanical and aspiration assistance. The method comprises the steps of providing an aspiration catheter having a central lumen and a distal end, advancing the distal end of the aspiration catheter to obstructive material in a vessel, applying vacuum to the central lumen to draw clot into the central lumen, introducing a thrombus engagement tool into the central lumen, and manually manipulating the tip to engage clot between the tip and an inside wall of the central lumen.

An invention for transfixing a plurality of cannulas 14 through a tissue 25 for providing a plurality of entry-ports 33 to a surgical site 26, comprising: a base 10; and a plurality of cannulas 14 connected to said base 10; wherein each said cannula 14 includes an access-port 3, is provided. Also, the invention for transfixing a plurality of cannulas 14 through a tissue 25 for providing a plurality of entry-ports 33 to a surgical site 26, comprising: a sleeve 9 including a base 10; said sleeve 9 including a plurality of cannulas 14 connected to said base 10; a mandrel 1 including a handle 7; and said mandrel 1 including a plurality of piercing tips 2 connected to said handle 7; wherein said mandrel 1 detachably engage said sleeve 9 forming a single punch assembly; wherein said cannula 14 includes an access-port 3 to a surgical site 26, is provided.

Access assemblies includes an instrument valve housing and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a guard assembly, a seal assembly disposed adjacent to the guard assembly, and a centering mechanism for maintaining the seal assembly and guard assembly centered within a cavity of the instrument valve. In embodiments, the seal assembly includes a plurality of seal sections that are movable from an unfolded configuration to folded configuration in which the seal assembly forms a hexagonal member defining an opening to facilitate sealed passage of a surgical instrument. The seal sections may include a tapered inner edge for engaging a surgical instrument inserted through the instrument valve housing.

Disclosed herein are sealing devices configured for improving sealing functionality with an engaged extension member of an apparatus. More specifically, disclosed herein are trocar sealing devices configured for improving insufflation gas containment in relation to trocars (and/or other related type of devices) that are used for enabling a surgical instrument such, for example, a laparoscope, to gain access to an abdominal cavity (or other body cavity). By providing for such improved insufflation gas containment, sealing devices as disclosed herein are particularly advantageous, desirable and useful in view of long-standing reasons for limiting insufflation gas leakage and in view of newly recognized reasons stemming from outbreak of COVID-19 disease for limiting insufflation gas leakage.

A thrombus engagement tool having a flexible shaft, a clot engagement tip, and a handle. The engagement tip may include one or more radially outwardly extending structures such as a helical thread. The helical thread can be advanced through a catheter to engage a clot. The handle may be configured to be rotated by hand. When the handle is rotated, the helical thread of the engagement tip can rotate in the same direction thereby allowing the helical threat to engage the clot. The helical thread can wrap around the flexible shaft at least about one, two, or four or more full revolutions, but in some cases no more than about ten or no more than about six revolutions.
