Described herein is combination sealing and stabilizing collar component designed to both prevent the leakage of vacuum through the interface between an endoscopic shaver device and a powered handpiece that provides rotational motion thereto and stabilize the endoscopic shaver device when it is mounted onto the powered handpiece. The collar may be further coupled with a conventional cannula to prevent the leakage of intra-articular fluid when performing an arthroscopic procedure.

Access devices including access ports and retractors, which enhance the working area and access to a surgical site. The access port includes a tubular body with at least one sidewall defining an interior path along the length of the tubular body. The sidewall includes a rigid portion and a flexible portion. The flexible portion is able to stretch or deform, for example, to accommodate an angled trajectory of a surgical implement. A surgical access device for retracting tissue includes a plurality of retractor blades. The outer surface of the retractor blades form a substantially circular cross-sectional configuration with a plurality of spiral ridges projecting therefrom such that advancement of the retractor into the surgical site may be improved.

An injection catheter system that includes (a) an actuator; (b) an outer needle comprising a sharp tip and a tubular body defining a lumen, and extending distally from the actuator; and (c) an inner needle at least partially disposed within the lumen and extending distally from the actuator, the inner needle having a distal tip configured such that at least a portion of the distal tip has a surface contour with an interstitial cavity adapted to receive a therapeutic gel. The system is configured such that (a) in a first position, the distal tip is fully disposed within the lumen to temporarily retain the therapeutic gel in the interstitial cavity and (b) in a second position, the outer needle is retracted proximally, exposing the interstitial cavity to deliver the therapeutic gel to a target area in a body.

A catheter device 10 with a cutting structure or means 16 on the distal portion 14 is disclosed, along with a medical procedure for using the device. The catheter 10 is configured in such a way as to create a permanent interatrial aperture in the heart, including creating a permanent interatrial hole and/or removing tissue.

An anatomic structure extractor allows a medical practitioner to retract, aspirate, ligate and amputate an anatomic structure within a patient through a minimally invasive incision. An anatomic structure extractor may include a transparent tubular member with a cap coupled to one end. The cap may have at least one view port with a magnifying lens. The cap may also have a needle port through which a needle is inserted to puncture the anatomic structure. A trap may be in fluid communication with the transparent tubular member. A suction post is in communication with the trap to pull the contents of an aspirated cyst into the trap. A light post containing a light source may be connected to the transparent tubular member to illuminate the interior of the extractor. A ligature deployer and a cutting wire may also be coupled to the tubular member.

Embodiments described herein provide devices, systems, and methods that reduce the distance between two locations in tissue, often for treatment of congestive heart failure. For example, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. The anchor may be deployed into the heart through a working lumen of a minimally invasive access tool. The minimally invasive access tool may have a plurality of grippers near a distal end of the working lumen. The grippers may engage epicardial tissue of the heart and may be moved radially inwardly relative so as to provide stabilization of the epicardial tissue and/or hemostasis near an access site where the anchor is inserted through the epicardium. The minimally invasive access tool may minimize blood loss from the access site and improve anchor implant processes.

A surgical instrument includes a cannula and a member coupled to the cannula. The member includes a first locking element. The surgical instrument further includes a patient attachable ring having a second locking element configured to engage the first locking element to fix the cannula relative to the patient attachable ring. Systems and methods are disclosed.

A surgical instrument includes a first member defining a passageway defining a first axis. A second member is positioned in the passageway and includes a lip extending at an angle relative to a second axis defined by the second member that engages a flange of the first member. A third member engages an outer surface of the first member. The third member includes an end surface. A fourth member defines a pathway having the first and second members disposed therein. The fourth member includes a first locking element. A fifth member includes a body including an inner surface that engages the third member. The fifth member includes a plurality of straps extending outwardly from the body. At least one of the straps includes a second locking element that engages the first locking element to fix the fourth member relative to the fifth member. Systems and methods are disclosed.
