Abstract
Systems, devices, and methods capable of retracting organs are disclosed. In one embodiment, a retractor body comprises a deformable resilient frame defining a central opening and a deformable membrane extending across a portion of the central opening wherein the deformable resilient frame is arranged for complete disposal within the body of a patient and for varying the size of the central opening. In some exemplary embodiments, the retractor is arranged to form a helically coiled arrangement for insertion into the body of a patient. Delivery devices for delivering a deformable resilient retractor and methods of delivery are also disclosed.
Claims16
A biocompatible retractor, comprising:
- a retractor body comprising a deformable resilient frame that extends around and defines a central opening surrounded by the frame and a deformable membrane coupled to said deformable resilient frame and extending across a portion of said central opening;
- wherein said central opening has a circumferential length;
- wherein said deformable resilient frame is arranged to vary the circumferential length of the central opening, said deformable resilient frame having a first end slidably received within an opening defined by a second end of the deformable resilient frame and said deformable resilient frame being self-expandable from a contracted configuration to an expanded configuration;
- and
- wherein the retractor body is arranged for complete disposal within the body of a patient.
A biocompatible retractor for insertion beneath the skin of a patient, comprising:
- a retractor body comprising a deformable resilient frame that extends around and defines a central opening surrounded by the frame and a deformable membrane coupled to said deformable resilient frame and extending across a portion of said central opening;
- wherein said deformable resilient frame has a first end slidably received within an opening defined by a second end of the deformable resilient frame and said deformable resilient frame is telescopically configurable between a contracted configuration and an expanded configuration arranged to retract tissue;
- wherein said deformable resilient frame is self-expandable from a contracted configuration to an expanded configuration;
- wherein said contracted configuration is arranged for laparoscopic insertion through the skin of a patient;
- and
- wherein said deformable resilient frame in said expanded configuration and said deformable membrane are arranged for complete disposal within the body of a patient.
An assembly for delivering a retractor beneath the skin of a patient, comprising:
- an elongated body comprising a proximal end region, a distal end region, and a retractor coupling portion positioned in said distal end region;
- and
- a deformably resilient retractor comprising a deformable resilient frame and a deformable membrane coupled to the deformable resilient frame, said deformably resilient retractor helically wound around said elongated body;
- wherein said retractor coupling portion is coupled to a portion of said deformably resilient retractor;
- and
- wherein said retractor coupling portion is arranged to move said portion of said deformably resilient retractor between a first position outside of the body of the patient and a second position beneath the skin of the patient.
