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. | 2022-01-13 |
20220008059 | MINIMAL-ACCESS PERCUTANEOUS AND SELF-RETRACTING SURGICAL SYSTEM - Disclosed herein are embodiments of a minimally-invasive surgical system and methods of use which can mimic a mosquito proboscis to efficiently penetrate tissue. The delivery system can utilize a plurality of modular strut instruments to create a working tissue canopy and apply any number of surgical actions to a target tissue. | 2022-01-13 |
20220008060 | VASCULAR ANCHORING INTRODUCER SHEATH - Among other things, there is disclosed structure and methods for maintaining access to a location in the body while reducing or eliminating the potential for pulling an access device (e.g. a catheter) back through an opening. An introducer sheath includes a distal indented portion and a balloon, so that once placed in a desired location through tissue, the balloon can be inflated to anchor the sheath against retraction. In particular embodiments, structure and methods for accessing the pericardial cavity via the right atrial appendage are shown. | 2022-01-13 |
20220008061 | NON-SLIDING SOFT ANCHOR - A method for coupling tissue includes aligning a guide tool on an outer surface of a first tissue; forming a bore in the first tissue aligned with the guide tool; deploying a non-slip suture construct through the (wide tool and into the bore; adjusting a saddle along a flexible member to a position adjacent to a soft anchor, wherein the saddle prevents the flexible member from slideably moving relative to the soft anchor; and threading the flexible member through a second tissue to secure the second tissue to the first tissue. | 2022-01-13 |
