The present disclosure is directed to a reversibly removable self-adjusting, perforating and/or guiding port configured to automatically retract a perforating blade or guiding rod upon entering a body cavity, while providing a substantially hermetic seal across the body cavity's wall.

A surgical access system comprises a first access device and a second access device. The first access device comprises expansile chambers which define inflation spaces. A region of overlap between the chambers of a first layer is offset from a region of overlap between the chambers of a second layer. The walls of the inflated chambers are movable for passage of an object such as a surgeon's arm/hand whilst maintaining a seal. The second access device comprises a housing, at least one valve mounted to the housing and a flexible film to which the housing is mounted.

A surgical rib cutter is disclosed. The surgical rib cutter includes a housing defining one or more guide slots. The surgical rib cutter also includes an anterior arm unit comprising an anterior effector configured to interact with an anterior side of a rib. The surgical rib cutter further includes a posterior arm unit comprising a posterior effector configured to interact with a posterior side of said rib. The surgical rib cutter also has an actuator movable relative to the housing and operationally coupled to at least one of the anterior and posterior arm units to move said at least one of the anterior and posterior arm units within at least one of the one or more guide slots to create a relative movement between the anterior and posterior arm units, said relative movement causing one of the anterior effector or the posterior effector to create a green stick break in said rib.

A delivery device for installing a medical device in a patient comprising a body portion having a proximal end and a distal end, the distal end having a chisel shaped tip, a receptacle disposed in the distal end of the body portion for receiving a medical device for implanting in the patient, a handle disposed at the proximal end of the body portion for facilitating advancement of the proximal end of the body portion into the patient.

A method of accessing a thoracic cavity; inserting, in an insertion direction, a thin elongated body, from outside the body, through a space between adjacent ribs, to within the thoracic cavity; expanding the elongated body in a direction including a component perpendicular to the insertion direction to generate an elongated body lumen therein.

A lead receptacle having a lumen configured to traverse from an outer side of an outermost intercostal muscle to an inner side of an innermost intercostal muscle of an intercostal space of a patient and to support a lead traversing through the lumen. The lumen being configured to support one or more cardiac leads traversing through the intercostal space.

A surgical assembly is disclosed. The assembly has a cannula. The cannula has an oblong opening on a proximal end, one or more textured features on an outside, and a stabilizer at the proximal end. The assembly also has an obturator sized to fit within the cannula from the proximal end of the cannula. The obturator has a tapered end configured to extend from the distal end of the cannula and a protrusion on a proximal end of the obturator configured to engage a portion of the cannula.

Systems, devices, and methods for providing access to the heart. The system includes an intracardiac access device comprising an elongate member having a channel extending between a distal end and a proximal end thereof. The intracardiac access device is configured to be advanced through an extrapericardial penetration in the left atrial wall without penetrating the pericardium of the heart. An optional procedural device is configured to be advanced through the channel of the intracardiac access device into an internal chamber of the heart and configured to perform a surgical procedure in the internal chamber of the heart. A working channel of an optional suprasternal access device is configured to facilitate access of the intracardiac access device into the body of the patient by providing a path from a suprasternal opening to a position adjacent the roof of the left atrium.

A cannula incorporating a blood wicking/diversion mechanism to absorb and/or obstruct blood from running down the cannula onto an endoscope inserted therein, and/or the procedure site, thereby obfuscating the field-of-view during a thoracic procedure. In an embodiment the device comprises an elongate woven fabric wick contained within an open-faced lumen molded into the bottom wall of the cannula tubular body and running along its length to absorb blood or fluid running down its length. In another embodiment the wick is formed in a sleeve-like configuration slightly larger in diameter than tubular body (configured for slidable insertion thereon) woven back into a string at the distal end. Alternatively the device comprises an expandable dome-shaped hood attached to the cannula.

The present invention provides a chest tube introducer which can be inserted without a need of surgical procedures. The chest tube introducer comprises a series of compartmentalized leakproof sealing devices, which is configured for safe introduction of the chest tube introducer minimizing a risk of pneumothorax.
