Systems, devices, and methods for endoscopically retracting a target tissue. The device includes a first shaft and a second shaft slidably coupled thereto. An internal member extends in a transverse direction from the first shaft and is configured for advancement through a penetration in the target tissue to atraumatically engage a distal surface of the target tissue after being advanced therethrough. A pair of external members extend from the second shaft generally parallel to the transverse direction. The external members are spaced apart and are configured to atraumatically engage a proximal surface of the target tissue when the internal member is moved longitudinally relative to the external members. The internal member applies traction to the target tissue when retracted past the pair of external members, which apply counter-traction to the target tissue on opposing lateral sides of the internal member, to re-shape the target tissue and enable subsequent suture placement.

Patient-mounted retractors with varying configurations and/or features are provided, along with additional components for use therewith in provided patient-mounted retractor assemblies. Blade type and tube type patient-mounted retractors that may be re-positioned during the course of a procedure are provided in varying configurations and/or geometries suitable for varying procedures and/or patient anatomies. Applications of re-positionable patient-mounted retractor assemblies are particularly suitable for use in minimally invasive procedures, eliminating the need for table-mounted retraction assemblies and/or cannulas that restrict the operating environment.

A device for creating an intercostal transcutaneous access to an, in particular endoscopic, operating field including a base body, which closely surrounds an incision all-side frame-shaped and with at least two webs mounted on the base body, which can be introduced into an intercostal space, by which two ribs arranged next to each other can be moved apart. To create a device for creating an intercostal transcutaneous access to an, in particular endoscopic, operating field which allows individual pressing apart of the ribs, it is proposed according to the invention that the at least two webs are mounted adjustable relative to each other on the base body.

A cannula seal assembly with a compatible flexible cannula. The cannula includes a rigid cannula body having proximal and distal body ends. The cannula body is composed of material having a first thickness. A flexible thread extends along at least a portion of the cannula body from the distal body end toward the proximal body end. The thread is composed of material having a second thickness, which is less than a first thickness. The cannula is attachable to a cannula seal assembly. The assembly includes a housing having a primary seal and a secondary seal therein. The assembly has a spacer connected between the primary seal and the secondary seal and a reservoir between the primary seal and the secondary seal.

A surgical access device including a housing having a nozzle assembly, a gas supply plenum, a gas return plenum, and a pressure sensing plenum, as well as an elongated tubular body that extends from the housing portion and defines a central lumen communicating with the nozzle assembly and the gas return plenum, a telescopic cannula assembly associated with the tubular body and including a proximal section arranged coaxially within the tubular body and a distal section coaxially supported within the proximal section and mounted for movement relative to the proximal section between retracted and extended positions, and an elastomeric sheath associated with the telescopic cannula assembly and having a distal anchor portion for securing the surgical access device during a laparoscopic surgical procedure.

The present invention discloses a self-sealing cannula and methods of its use. The self-sealing cannula can be minimally invasively placed into the heart for drawing and/or returning blood with a self-sealing function at the interface of the blood access site. The disclosed cannula can be implemented as a single lumen cannula or a double lumen cannula, which can be used with ventricular assist devices for heart support or pump-oxygenators for ECMO and respiratory support. Through a self-sealing mechanism fixed on the ventricular wall or atrial wall, a cannula body is attached to the self-sealing fixture and blood is drawn into the lumen via an external pump and returned to the circulation system through a separate cannula. In the case of the double lumen cannula embodiment, the blood will be drawn into the drainage lumen of the double lumen cannula and returned through an infusion lumen at the desired location. The present invention achieves minimally invasive insertion without surgical sutures to the heart, and allows for optimal drainage of the blood from the heart. With use of the double lumen cannula, it prevents need for multiple cannulation sites, and greatly reduces the blood recirculation. Removal of the cannula is simplified without need for suturing or insertion of a plugging member.

A single body port or body flange access device and method for performing laparoscopic surgery are disclosed. The device comprises a plurality of crisscrossing conduits through which surgical instruments may be inserted. The instruments are manipulated so that triangulation is obtained using one patient body flange while standard surgical procedures are performed on the patient.

The present disclosure describes a uterine contraction device which may be utilized to treat and/or prevent postpartum hemorrhaging. The uterine contraction device includes a catheter and a pressure seal adjustably coupled to the catheter. A distal section of the catheter is configured for insertion into the uterus, and a proximal end of the catheter is configured for attachment to a vacuum device. Negative pressure generated by the vacuum device is transmitted to the distal section, while the pressure seal forms a seal at the vaginal introitus to maintain the negative pressure within the uterus to assist in contracting the uterus.

A system and method for passing an end portion of a needle system from a body cavity to an outer environment through a laparoscopic port is provided. The system comprises a seal bridge which comprises an elongated body. The seal bridge is telescopically introducible at a first proximal end, through a first lumen in the port and bypassing a seal mechanism of the laparoscopic port. The seal bridge is adapted to be inserted through the proximal opening port to be deployed in the lumen of the port and thereby bridging across and/or deactivating the seal of the port. The method comprises positioning a distal portion of a needle shaft from within the body cavity into the port lumen and across the seal opened by the seal bridge.

A collar for a surgical access device includes an annular body laterally attachable to a cannula of the surgical access device. A spring is coupled to the annular body and movable between an uncompressed state and a compressed state. The spring is configured to manipulate the annular body between a first condition and a second condition to selectively fix the annular body at predetermined locations along the cannula or to laterally remove the annular body from the cannula while the cannula is supported within a patient's body.
