Abstract: A trocar system for endoscopic surgery, cap assembly, and related methods are provided. The cap assembly includes a valve housing with an opening formed in line with an axis of the valve housing and also includes a valve positioned adjacent the opening of the valve housing. The valve body includes a proximal valve section including a valve ring positioned within the valve housing, and a distal valve section extending axially from the proximal valve section. The distal valve section includes a valve extension having a proximal and distal end portions, and a substantially conically shaped medial portion connected to and extending therebetween, wherein a plurality of friction-reduction features, preferably tear-drop shaped knobs, are disposed proximate the distal end portion and extending a distance in the medial portion of the valve.

Abstract: A trocar system is provided which preferably includes a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A trocar having an elongate trocar body also extends through the cannula. The elongate trocar body has a sharpened distal end portion, a medial portion thereof having a first diameter, and a proximal portion having a second diameter. The second diameter is preferably larger or greater than the first diameter.

Abstract: A trocar system for endoscopic surgery, cap assembly, and related methods are provided. The cap assembly includes a valve housing with an opening formed in line with an axis of the valve housing. The cap assembly also includes a valve positioned adjacent the opening of the valve housing. The valve includes a valve body with an annular-shaped valve opening for receiving elongate tools with differing diameters so that a seal is maintained between the valve opening and any of the plurality of elongate tools. The valve body includes a proximal valve section including a valve ring and positioned within the valve housing and includes a distal valve section extending axially from the proximal valve section. The distal valve section includes a valve extension having a proximal end portion, a distal end portion, and a substantially conically shaped medial portion connected to and extending therebetween.

Abstract: A cap assembly of a trocar system for endoscopic surgery includes a valve housing with an opening formed in line with an axis of the valve housing. The opening being defined by axially extending sidewalls. The cap also includes a valve positioned adjacent the opening of the valve housing. The valve includes a valve body with an annular-shaped valve opening for receiving elongate tools with differing diameters, so that a seal is maintained between the valve opening and any of the plurality of elongate tools. The valve body has a layer of a fabric material, a layer of elastomeric material, and a periphery valve section connected to and extending radially outwardly from peripheries of the valve body. The periphery valve section has rib members that extend radially a distance between an outer perimeter of the valve body and an outer perimeter of the periphery valve section.

Abstract: A septum valve having peripheries thereof adapted to be fixedly positioned in a valve housing of a trocar system is provided. The septum valve includes a valve body having an opening positioned in a medial portion of the valve body and adapted to individually and separately receive a plurality of different elongate tools each having a different diameter therethrough so that when any one of the plurality of elongate tools is positioned through the valve opening a septum seal is maintained between peripheries of the valve body surrounding the valve opening and abuttingly contacting outer peripheries of the any one of the plurality of elongate tools extending therethrough. The valve body has first and second layers of a fabric material and a layer of elastomeric material positioned between and contacting each of the first and second layers of the fabric material.

Abstract: A trocar system is provide which preferably has a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A pair of finger grips are each connected to and extending outwardly from the proximal portion of the cannula body for gripping the cannula with the fingers of a hand of a user. A trocar having an elongate trocar body is positioned to extend through the cannula body. The trocar also having a handle connected to the trocar body for gripping of and handling of the trocar by a hand of a user.
