Seal anchor with non-parallel lumens
A seal anchor member defines a housing defining a longitudinal axis, the housing having leading and trailing ends, and including a plurality of lumens extending between the leading and trailing ends, each lumen being adapted for substantially sealed reception of an object therein and defining a longitudinal axis, wherein at least two of the lumens define longitudinal axes that are intersecting. The seal anchor member may be formed from a compressible material.
1. A surgical device comprising:
a housing formed of a compressible foam material and having a longitudinal axis, the housing having a proximal end, a distal end, and an intermediate portion, the intermediate portion having a radial dimension that varies along the longitudinal axis of the housing to facilitate anchoring of the device in tissue;
the housing defining two or more lumens extending between the proximal and distal ends, the two or more lumens being non-parallel with respect to the longitudinal axis of the housing, the two or more lumens crossing one another without intersecting, and the two or more lumens being adapted to receive surgical instrumentation therethrough, the two or more lumens having diameters that contract in the absence of the surgical instrumentation and being adapted to expand to accommodate the surgical instrumentation in a sealed manner, wherein the distal end of the housing defines a groove in a half-cylindrical configuration, a depth of the groove varying along a length of the housing such that a center portion of the groove has a first depth and a lateral portion of the groove has a second depth less than the first depth.
2. The device according to claim 1 , wherein the two or more lumens of the housing includes three lumens.
3. The device according to claim 1 , wherein the housing includes an insertion feature insertion feature disposed in the proximal end of the housing.
4. The device according to claim 1 , wherein the proximal end of the housing and the distal end of the housing are arranged to engage walls defining a body cavity of a tissue tract.
5. The device according to claim 1 , wherein the compressible foam material is selected from the group consisting of polyisoprene, urethane, and silicone.
6. A surgical device comprising:
a housing formed of a compressible material and defining a longitudinal axis, the housing having a proximal end, a distal end, and an intermediate portion, the intermediate portion having a dimension that varies along the longitudinal axis of the housing;
the housing defining two or more lumens extending between the proximal and distal ends, each lumen of the two or more lumens defining an acute angle with respect to the longitudinal axis of the housing, the two or more lumens being adapted to receive surgical instrumentation in a sealed manner, wherein the distal end of the housing defines a groove in a half-cylindrical configuration such that a depth of the groove varies along the longitudinal axis of the housing such that a center portion of the groove defining concavity has a first depth and a lateral portion of the groove has a second depth less than the first depth.
7. The device according to claim 6 , wherein the proximal and distal ends of the housing are configured to engage an opening in tissue.
8. The device according to claim 6 , wherein the housing is formed of a foam material.
9. The device according to claim 8 , wherein the foam material of the housing is selected from the group consisting of polyisoprene, urethane, and silicone.
