Abstract
Abstract Replaceable cohesive-adhesive pads are provided for vessel occluding devices of both the tie-on and jaw-clamp types. When applied to an anatomical vessel the pads act collectively with the fibrous surface of the vessel to produce an adherence relationship therewith. The pads are shown secured in place through either sleeve-like connections, or button-headed connector which snap into secure engagement with undercut recesses.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
102 words
A vessel occluding instrument for facilitating the treatment of an anatomical vessel, said instrument comprising: an elongated generally rigid body member having top and bottom surfaces; resilient pad means secured to the bottom surface of said body member, said resilient pad means comprising a cohesive-adhesive covering sheet for releasably and atraumatically securing said pad means to said vessel, whereby said sheet and said vessel collectively produce an adherence relationship therebetween; and clamp means secured to said body member in apposition to the bottom surface thereof to selectively draw said vessel into adherence relationship to the covering sheet of said resilient pad means.
Claim 2
Dependent Claim
102 words
A vessel occluding instrument for facilitating the treatment of an anatomical vessel, said instrument comprising: an elongated generally rigid body member having top and bottom surfaces; resilient pad means secured to the bottom surface of said body member, said resilient pad means comprising a cohesive-adhesive covering sheet for releasably and atraumatically securing said pad means to said vessel, whereby said sheet and said vessel collectively produce an adherence relationship therebetween; and clamp means secured to said body member in apposition to the bottom surface thereof to selectively draw said vessel into adherence relationship to the covering sheet of said resilient pad means.
Claim 3
Dependent Claim
37 words
A vessel occluding instrument according to claim 1 wherein said rigid body member comprises a first jaw and the clamp means comprises a second jaw hingedly secured to said first jaw for movement towards and away therefrom.
Claim 4
Dependent Claim
61 words
A vessel occluding instrument according to claim 2 wherein said second jaw has a top surface in apposition to the first jaw, said instrument further comprising a cohesive-adhesive covering sheet on said top surface for releasably and adhesively engaging said vessel upon drawing of said vessel into adherence relationship to the covering sheet of said first jaw by said second jaw.
Claim 5
Dependent Claim
58 words
A vessel occluding instrument according to claim 2 wherein said second jaw has a top surface in apposition to the first jaw, said instrument further comprising a resilient cushion on said top surface for engagement with said vessel upon drawing of said vessel into adherence relationship to the covering sheet of said first jaw by said second jaw.
Claim 6
Dependent Claim
101 words
A vessel occluding instrument according to claim 1 wherein the resilient pad is releasably secured to the body member by a structure comprising: an elongate channel formed in the body member, said channel having an enlarged section within the body member and a convergent section opening through said bottom surface; an elongate bead carried by the resilient pad, said bead being received within said enlarged section and being of a cross-section greater than that of said convergent section; and an opening at one end of said channel to provide for passage of said bead into and out of said enlarged section.
Claim 7
Dependent Claim
34 words
A vessel occluding instrument according to claim 1 wherein said resilient pad is releasably secured to the body member by a sleeve attached thereto and proportioned for snug slidable receipt over the body member.
Claim 8
Dependent Claim
36 words
A vessel occluding instrument according to claim 6 wherein said sleeve includes an elastomeric cushion so disposed as to be positioned between said pad and bottom surface upon receipt of the sleeve over the body member.
Claim 9
Dependent Claim
17 words
A vessel occluding instrument according to claim 7 wherein said elastomeric cushion includes a gel filled chamber.
Claim 10
Dependent Claim
76 words
A vessel occluding instrument according to claim 1 wherein the resilient pad is releasably secured to the body member by structure comprising: a resilient backing strip affixed to the pad; at least one pair of button-head protrusions fixed to and extending from said backing strip; and a pair of sockets formed in the bottom surface of the body member, said sockets being proportioned for receipt of said protrusions and positioned and undercut for simultaneous engagement thereover.
Claim 11
Dependent Claim
20 words
A vessel occluding instrument according to claim 9 further comprising an elastomeric cushion interposed between said pad and backing strip.
Claim 12
Dependent Claim
76 words
A surgical clamp comprising a pair of opposed jaws operatively connected together for movement towards each other to clamp an anatomical vessel therebetween, at least one of said jaws having resilient pad means secured thereto for engagement with a vessel clamped between the jaws, said pad means having a cohesive-adhesive surface for releasably and atraumatically securing said pad means to a vessel clamped between said jaws whereby said surface and vessel produce an adherence relationship therebetween.
Claim 13
Dependent Claim
76 words
A surgical clamp comprising a pair of opposed jaws operatively connected together for movement towards each other to clamp an anatomical vessel therebetween, at least one of said jaws having resilient pad means secured thereto for engagement with a vessel clamped between the jaws, said pad means having a cohesive-adhesive surface for releasably and atraumatically securing said pad means to a vessel clamped between said jaws whereby said surface and vessel produce an adherence relationship therebetween.
Claim 14
Dependent Claim
28 words
A clamp according to claim 11 wherein the jaw opposite said one jaw is provided with resilient pad means for engagement with a vessel clamped between said jaws.
Claim 15
Dependent Claim
75 words
A surgical clamp comprising a pair of jaws connected together for movement towards and away from each other, said jaws having opposed clamping surfaces; and resilient pad means secured to said surfaces for engagement with the opposite sides of a anatomical vessel clamped therebetween, said resilient pad means having cohesive-adhesive surfaces for releasably and atraumatically engaging a vessel clamped between said jaws whereby said surfaces produce an adherence relationship with opposite sides of said vessel.
Claim 16
Dependent Claim
75 words
A surgical clamp comprising a pair of jaws connected together for movement towards and away from each other, said jaws having opposed clamping surfaces; and resilient pad means secured to said surfaces for engagement with the opposite sides of a anatomical vessel clamped therebetween, said resilient pad means having cohesive-adhesive surfaces for releasably and atraumatically engaging a vessel clamped between said jaws whereby said surfaces produce an adherence relationship with opposite sides of said vessel.
